1. Introduction
RME’s ADI-2 Pro, a true milestone, was released in 2016. Followed by the ADI-2 DAC, ADI-2 Pro
AE (Anniversary Edition), ADI-2 Pro FS, ADI-2 Pro FS R BE and lately the ADI-2/4 Pro SE, RME
has successfully combined usability with flexibility, and brought professional features into the
home and HiFi market.
7 years later RME once again shows what long-term relationship between RME developers and
RME customers means: The newly released ADI-2 Remote for macOS, Windows and iPadOS
not only comes for free, but also supports ALL devices of the ADI-2 series, back to the very first
ADI-2 Pro from 2016!*
The software ADI-2 Remote can be downloaded from RME’s website:
Windows: https://www.rme-audio.de/downloads/adi2remote_win.zip
macOS: https://www.rme-audio.de/downloads/adi2remote_mac.zip
iPadOS: available via Apple’s App Store as ADI-2 Remote.
Please note the below system requirements, for updated firmware, matching driver and computer
hardware.
* The original ADI-2 AD/DA converter does not have USB or DSP, and as such is not part of this series.
2. System Requirements
Firmware
For the software to communicate with the ADI-2 device, and to support all final features, make
sure you have these latest firmware versions in use:
ADI-2 DAC: USB 80, DSP 59
ADI-2 Pro: USB 266, DSP 122
ADI-2/4 Pro SE (Hw Rev 6): USB 71, DSP 36
ADI-2/4 Pro SE (Hw Rev.7): USB 206 or 208, DSP 36
The latest firmware version comes in a FUT (Firmware Update Tool), download here:
Windows: https://www.rme-audio.de/downloads/fut_madiface_win.zip
macOS: https://www.rme-audio.de/downloads/fut_madiface_mac.zip
Windows
The ADI-2 Remote uses the same graphics engine as DigiCheck NG, so the same system re-
quirements apply: Windows 10 or higher, and a graphics card that supports Direct3D 12. This
might exclude some older computers, even when running Windows 10, for example with Intel
integrated graphics HD4600 and HD4000.
More information on Direct3D and an overview of supported graphics cards is available here:
https://en.wikipedia.org/wiki/Feature_levels_in_Direct3D
For Windows the MADIface series driver 0.9827 or higher is required.
iPadOS
The iPad app requires iOS 12.4 or higher. It therefore can be used with the original iPad Air and
any later (newer) iPad or iPad Pro.

User’s Guide ADI-2 Remote - v 1.0
macOS
The ADI-2 Remote uses Metal for its graphics, therefore won’t work below macOS 10.11. With
10.11 it depends on the hardware as not all Macs running that OS are Metal compatible. See
here: https://support.apple.com/en-us/HT205073
No driver is required.
Connection
Under the hood the ADI-2 Remote uses a USB MIDI port to communicate with the hardware
device. The connection is the same as usual –via USB 2.0 to a Windows computer, a Mac com-
puter, or an iPad.
When everything is connected and up to date, but the app’s title still says Disconnected: check
that the MIDI Control option is set to ON (menu Device Mode for ADI-2 Pro and ADI-2/4 Pro,
Remap Keys/Diag for ADI-2 DAC).
3. Software Installation
There is not much to say –the apps come with installer, started by a double-click on the unzipped
archive.
4. After Installation: First Step –Perform a Backup!
This part is important as you don’t want to change or lose your current settings on the
device. Simply follow these instructions!
Install the app, connect the ADI-2 DAC, start the app. Stop there.
Now there is a fundamental rule on how the app works: it will only read out the ADI-2’s current
state and NOT CHANGE ANYTHING on the device –unless you fiddle with the knobs or settings
–don’t yet!
Next go to the File menu, select File - Save Setup as.... This stores the current state (Setup)
including all 20 PEQ Presets of the ADI-2 into a Setup file (*.adistp) that can be loaded later. Now
you are safe and covered! Whatever you change using the ADI-2 Remote app can be undone
easily by loading this setup file from the same menu, File - Open Setup file.
Additional steps
If you have saved several Setups in the unit you can store all these into separate files as described
above, after loading the respective Setup:
In the app go to the Device page, click Load, then click Setup 1. This is the same as loading Setup
1 from the unit's display menu. Now save the current state as file. Repeat the process with all
user-defined Setups.
There currently is no 'global state including all Setups' save functionality, so saving the Setups
has to be done sequentially for all user-stored Setups, one by one.
Now start using the ADI-2 Remote - Have fun!

5. Overview
The ADI-2 Remote is a true remote –it mostly only reads out the device state, and controls it like
when doing the same on the unit or the MRC. All the intelligence, rules and know how are still in
the unit, all reactions are controlled and performed by the unit –not by the software.
There is one exception, though:
Link
The device has a special Dual Volume mode to control two outputs simultaneously. The app offers
Link instead, which links (or gangs) any of the output volume settings controlled by the app.
It is possible to activate Dual Volume on the unit, but then the app will control not both but only
one channel per time –unless Link is activated on the same channels.
The Link state is remembered by the app on restart, but volume values are not. Once again the
current values are just read out of the device –which is enough to make it work correctly after a
shutdown or reboot.
The Pages
The app consists of several main pages:
Line Input (for 2 Pro and 2/4 Pro)
Line Out, Phones Out, IEM Out for the DAC, Phones Out 1/2 and Phones Out 3/4 for 2 Pro
and 2/4 Pro
A general Device page with all channel unrelated settings
A PEQ Editor that can be used to edit, save or load PEQs without changing the currently active
EQ (listen to music while you play with it…).
The app is interactive and fully synchronized. Change the volume on the unit or in the app –both
will stay in sync. When toggle mode is active and Toggle is clicked the current channel page will
change accordingly. Same when plugging/unplugging phones when Mute vs. xx is active. Etc.
If no device is found the app enters Demo mode with ADI-2/4 Pro SEshown, so anyone interested
can have a look.
In fact it is possible to create or edit PEQs even while offline, with the PEQ Editor, and load and
save these from/to disk.
The app itself has two Settings available directly from the app menu. One disables the automatic
change of shown output page. The other one enables to load up to 20 PEQs simultaneously into
the unit via a Setup file. This is a nice feature for copying device states quickly between units, but
usually users want to have full control what to load and then only load one or the other PEQ to
specific slots –that’s why this option is off by default.
Help
Although the app should be easy to use and self-explanatory - if something is unclear try the
included help from the menu (German and English).

6. Quick Guide (the shortest manual ever)
The ADI-2 DAC Remote software is simple and intuitive to use. The pages shown differ only
marginally between the devices. One thing of course that you don’t get with the ADI-2 DAC is the
hardware inputs of ADI-2 Pro and 2/4 Pro SE, complete with EQ for adjusting the signal on the
way in when you’re recording. In Demo mode these are also visible for ADI-2 DAC users.
The ADI-2/4 Pro SE also features a digital RIAA mode, removing the need to use an external
phono preamp in front of the ADI-2/4’s line inputs, and making it the ultimate choice if you’re
looking to archive your vinyl collection in the highest quality.
Page selection
Starting at the top there are tabs to access the configuration pages of input (not available on ADI-
2 DAC) and all outputs –click the tab for whichever output you wish to change the settings for,
for example the Phones 3/4 output.
Next up you have your Source
selection, which can be left set to
Auto, and the volume control.
You can also Lock the volume
from here, and apply Dim (tem-
porarily dropping the output level
–useful if you receive a phone
call etc), as well as control the
left/right balance and the Mute
switch.
Parametric Equalizer
Now we move into the EQ section. The ADI-2 series has long been popular for adjusting the EQ
curve to suit different pairs of headphone (check out RME’s latest video on that here), and now
you can do this straight from your Mac or PC itself!
After the EQ’s on/off switch, we have the eye-catching parametric equalizer, which features 5
adjustable bands, along with the bass and treble controls.
If you’re familiar with EQ then chances are you won’t need any explanation on how to use this
section, but here’s a quick run-through just in case:
Starting with a single Band (e.g.
Band 1), you’ll find three verti-
cally-stacked encoders. The top
is the gain control, which allows
us to increase or decrease the
level of the chosen band (with 0
being no boost or cut applied).
The middle encoder controls the
target frequency (20 Hz –20
kHz), whilst the third encoder ad-
justs the Q(Quality or Q Factor),
which alters the shape of the
curve for the EQ band.
Whilst there are no set rules
when it comes to EQing, a good
rule of thumb is that narrow Q settings are generally good for making cuts (-), whilst wider curves
are better for boosts (+), and tend to sound more natural.
Finally we also have the Bass and Treble controls. These two bands have fixed curve types (shelf
EQ), with the cut-off frequency for each band fully adjustable, along with the Q control.

User’s Guide ADI-2 Remote –v 1.0

Dual Button
To the right of the EQ we also have the Dual button. The ADI-2 DAC can famously apply EQ to
the left and right channels independently –great for those who are hard of hearing in one ear, or
if you want to make some slight room adjustments when connecting the DAC to speakers. Press-
ing this button allows us to create different EQ curves for the left and right channels.
Saving the EQ settings
The EQ section also allows you to save your settings as a preset. Click on the Store button and
give your preset a name, and choose whether you want to save it to your hard drive, or to one of
the ADI-2’s on-board memory slots.
Advanced Settings –Width, Crossfeed and Filtering
Next up we have the section labelled Advanced Settings. Here we can adjust the Width (from
stereo to mono to channels reversed), and try out the Crossfeed.
What is Crossfeed?
If you’ve not come across Crossfeed before, essentially it works by feeding a small amount of the
left channel into the right, and vice versa. Headphones provide a very isolated way of delivering
sound to our ears –in the real world, a sound source is received by both ears (albeit with a slight
delay between them, which helps us perceive what the direction a sound is coming from).
Crossfeed therefore emulates the experience of real-world listening –like when listening to a pair
of speakers, or watching a live band –by playing a small amount of sound from one channel into
the other. The effect of this tends to vary with different recordings, but can work very well on
certain types of music –well worth experimenting with!
The Advanced Settings is also home to the filter section, which allows you to change the type of
filtering the DAC uses, such as the SD Sharp or NOS filter. We can also swap the polarity here –
useful for checking that speakers aren’t aligned out of phase, or for checking phase issues in
music production –and activate the Mid/Side mode.
Loudness
We also have the very popular
Loudness section, which many
will remember from older HiFi
amplifiers. This clever feature
adjusts the treble and bass in re-
sponse to volume changes,
providing a more consistent lis-
tening experience regardless of
the volume level.
As with most things on the ADI-2’s, the treble and bass are user-adjustable, so you can fine-tune
them to find your perfect settings.
DC-Protection, De-emphasis and Loopback
Finally we have a switch for the DC-Protection filter, and the Deemphasis control (which allows
you to add or remove some of the highs on some digital material –more info can be found in the
ADI-2 unit’s manual), as well as the Loopback control which allows us to record the processed
playback signal, or use it with RME’s DIGICheck software.
That’s it for our quick run-through of the ADI-2 DAC Remote software. If you need more details
dive into the following chapters. And if that is not enough enter the most extensive and detailed
manual ever that came printed with your ADI-2!

7. App Menu
The menu and options are basically identical for macOS, Windows and iPadOS.
Options - Preferences
The app itself has two settings available directly from the app’s menu. One disables the automatic
change of shown output page, when toggling or plugging a headphone (Default: On). The other
one enables to load up to 20 PEQs simultaneously into the unit via a Setup file, as that file includes
all 20 PEQ Presets. This is a nice feature for copying device states quickly between units, but
usually users want to have full control what to load and then only load one or the other PEQ to
specific slots –that’s why this option is off by default.
Options - Enter Full Screen Mode
Author refused to explain this…
File - Load Factory –EQ Examples
This command will load 18 PEQ Presets into the PEQ Editor –page EQ Presets –NOT into the
device! But with the above global preference Store file-loaded EQ-Presets into Device all PEQs
in the device will be overwritten, so be careful! (No issue when you did the backup first –we told
you on page 4!).
These EQ Presets are examples on how to use the EQ and other interesting things. Here is some
background information on the examples:
1. Nomen est omen, but not for anyone
2. Sub-bass boost for in-ears. Intentionally with Peak filter to reduce boost
of the lowest, inaudible frequencies
3. Oratory1990 proposal for Sennheiser HD650
4. The author’s compensation for Audeze's LCD-X
5. The author’s compensation for Sennheiser HD800S
6. Oratory1990 proposal for HEDD Heddphone
7 to 10: compensation for DAC filters as published in RME’s forum
11: Turns an illegal digital square into a bandlimited, valid square that still
looks like a square
12: As the name says, different curves for left and right channel
13/14: Taken from the ADI-2 series manual. For details please read there.
15: Very effective rumble filter for turntables (Preset 22 in 2/4 Pro)
16/17: Using a subwoofer the sub could need some mid/treble reduction,
while the satellites need bass to be removed. These examples combined provide a proper cross-
over, but each one also works independently.
18: Hearing test. By changing the frequency of band 5 in real-time this hi-cut lets you find out at
what point you hear a difference in music playback. If you don't hear anything changed down to
12 kHz - don't worry, you are not alone...This one is called FM Tuner as FM radio (German UKW)
is typically limited to around 15 kHz audio bandwidth. Just for fun the famous MPX filter is added
as 19 kHz notch in Band 4.
19/20: Intentionally left empty. These two are useful to store modified PEQs, or when changing
the order (copy the slot to be overwritten to an empty slot first to not lose its content)

8. The Pages
8.1 Line Input (2 Pro and 2/4 Pro SE)
8.1.1 General
Conversion Type
PCM or DSD. Default: PCM. DSD
will not become active at sample
rates below 176.4 kHz. The DSD
rate changes with the chosen
sample rate (Device –Clock Set-
tings –Sample Rate).
Ref. Auto
ON or OFF. Default: OFF. In case of overload Auto Ref Level will switch the Ref Level to the next
higher setting. This process is repeated until +24 dBu is reached. In case Trim Gain was active it
will be set to 0 dB first. Not available in RIAA mode.
Ref Level
Sets the reference level for the analog inputs 1/2. Choices are +1 dBu, +7 dBu, +13 dBu, +19
dBu, +24 dBu, referenced to digital full scale level (0 dBFS).
8.1.2 Parametric EQ
On or Off. Default Off. See also
chapter 8.2.2 for further details on
PEQ settings.
Preset
Load or store up to 22 different EQ Presets. The first choice, Manual, holds the current, unsaved
EQ settings. The second choice, Temp, holds the settings of a loaded and then modified Preset.
This scheme lets the user easily change and compare three different EQ settings: the manual
one, the stored preset and the modified preset, without losing changes while listening to a different
set of EQ settings.
Preset 21, Clear, corresponds to the factory default with all bands at 0 dB. It is not available to
store a preset, but is used for resetting one by overwriting. A preset reset in this way, resulting in
an 'empty' preset, is marked with (lin).
The ADI-2/4 Pro SE has Rumble as Preset 22, a rumble filter for turntable usage.
The EQ Presets are independent from and not stored with Setups on the device. Using the app
Setup files do include all 20 PEQ Presets. On load the current EQ setting is written into the
memory slot Manual.

User’s Guide ADI-2 Remote - v 1.0
8.1.3 Advanced Settings
Digital Trim Gain
Digital amplification of the input
signal between 0 and +6 dB, in
steps of 0.5 dB. Main use is to
fine-tune the input sensitivity so
that it matches the reference out-
put level of external gear.
AD Filter
Short Delay Sharp, Short Delay Slow, Sharp, Slow. The analog to digital conversion can be done
using four different filters. Default is Sharp, offering the widest, most linear frequency response
at lowest phase distortion. Slow causes a small drop in the higher frequency range, but offers a
less aggressive (less steep) filter. SD Sharp and SD Slow are similar, but have lower latency and
are minimum phase filters.
DC Filter
RME (default), None. RME is a < 0.1 Hz filter in the FPGA with minimal phase error. In RIAA
mode this filter is always active. For DSD recording DC filters are not available.
Polarity
Inverts the phase (180°) on the corresponding channel.
M/S-Proc
Activates M/S processing. Monaural content is sent to the left, stereo to the right channel.
RIAA Mode
OFF, +14 dB, +20 dB, +26 dB, +32 dB, +38 dB. Default: Off. Activates an RIAA preamplifier and
equalizer with selectable gain for turntables with moving magnet cartridge (MM).
RIAA Mono Bass
OFF, Mono. Default: Off. Mono sums the bass below 150 Hz.
8.2 Line Output (all units)
8.2.1 General
Source
The source of the Line Output 1/2 signal is automatically selected based on the current mode:
Preamp: Analog inputs 1/2
USB: Playback channels 1/2
Dig Thru: current digital input signal
AD/DA: current digital input signal
DAC: current digital input signal and clock
The choice of AD/DA Source is
therefore usually not available.
Only in AD/DA and DAC mode
the input signal can be chosen
between Auto, SPDIF, AES and
Analog. This allows to choose be-
tween all currently attached digi-
tal input signals for conversion to
output 1/2.

User’s Guide ADI-2 Remote –v 1.0

Volume
Mirrors the direct volume control via Volume knob or encoder 1. The output level can be set be-
tween -96 dB and +6 dB, mostly in steps of 0.5 dB.
Lock Volume
Deactivates volume control via the big VOLUME knob.
Dim
Reduces the volume of the current output by 20 dB. Adjusting Volume to a higher value deac-
tivates Dim immediately, lowering Volume will set the Dim value as new Volume value.
Link
Links (or gangs) any of the output volume settings. This feature is similar but not identical to Dual
Volume on the device.
Ref. Auto
ON, Off. Default: ON.
Ref Level
Sets the reference level for the analog outputs 1/2. Choices are +1 dBu, +7 dBu, +13 dBu, +19
dBu, +24 dBu, referenced to digital full scale level (0 dBFS).
Balance
Mirrors the balance control in the VOL screen. Adjustable from L 100 (left) through <C> (center)
to R100 (right).
Mute
Mutes the output.
8.2.2 Parametric EQ
EQ Enable
ON, OFF. Default: OFF.
Preset
Load or store up to 22 different EQ Presets. The first choice, Man-
ual, holds the current, unsaved EQ settings. The second choice,
Temp, holds the settings of a loaded and then modified Preset. This
scheme lets the user easily change and compare three different EQ
settings: the manual one, the stored preset and the modified preset,
without losing changes while listening to a different set of EQ set-
tings.
Preset 21, Clear, corresponds to the factory default with all bands
at 0 dB. It is not available to store a preset, but is used for resetting
one by overwriting. A preset reset in this way, resulting in an 'empty'
preset, is marked with (lin).
The ADI-2/4 Pro SE has Rumble as Preset 22, a rumble filter for
turntable usage.
The EQ Presets are independent from and not stored with Setups
on the device. Using the app Setup files include all 20 PEQ Presets.
On load the current EQ setting is written into the memory slot Man-
ual.
Store
Opens a dialog to store the current PEQ settings as file or into the
device.

Adjustable from 20 Hz (200 Hz bands 4/5) to 20.0 kHz, in steps between 1 Hz and 100 Hz.
Band 1-5 Q
Quality factor is adjustable from 0.5 to 9.9 in bands 1 to 3, and 0.5 to 5.0 in bands 4 and 5, in
steps of 0.1 dB. This equals a bandwidth setting of 2.54 (0.5), 0.29 (5.0) and 0.146 (9.9).
Treble Gain
Current Treble amplification for the current channels as set by encoder 2 (T). Adjustable between
-12 dB and +12 dB in steps of 0.5 dB.
Treble Freq
Corner frequency of the shelf treble filter. Adjustable from 3 kHz to 10 kHz in steps of 100 Hz.
Default: 6.5 kHz.
Treble Q
The quality factor of the filter is adjustable from 0.5 to 1.5. Default 0.7.
Dual EQ
OFF or ON. Default: OFF. When set to ON, the 5-band parametric equalizer can be set individu-
ally for left and right channel.
B/T Enable
OFF, ON. Default: ON
B/T Load with EQ
The current B/T setting is always stored with the EQ Preset, but only loaded (automatically set
and activated) when this option has been set to ON. The Bode plot then shows the effect of the
B/T setting as well, and Bass and Treble controls are added as bands BB and BT for direct control
within the graphical EQ screen, turning the 5-band PEQ into a 7-band one.
Band 1 Type
Available settings are Peak, Shelf, High Cut and High Pass (Low Cut). All filters are adjustable
from 20 Hz to 20 kHz, at a Q of 0.5 to 9.9. Cut/Pass have a fixed 12 dB/oct filter steepness.
Band 5 Type
Available settings are Peak, Shelf or High Cut. High Cut is adjustable from 200 Hz to 20 kHz, at
a Q of 0.5 to 5.0 and a fixed 12 dB/oct.

8.2.3 Advanced Settings
Width
Defines the stereo width. 1.00 equals full stereo, 0.00 mono, -1.00 swapped channels.
Crossfeed
OFF, 1, 2, 3, 4, 5. The Bauer ste-
reo to Binaural crossfeed effect
emulates speaker playback by re-
ducing the stereo width in the tre-
ble range. Adjustable in 5 steps.
DA Filter
Short Delay Sharp, Short Delay Slow, Sharp, Slow, SD LD (Short Delay Low Dispersion), Brick-
wall, NOS. The Digital to Analog Converter chip offers several oversampling filters. Default is
Sharp, offering the widest, most linear frequency response at lowest phase distortion. Slow
causes a small drop in the higher frequency range, but has a less aggressive (less steep) filter.
SD Sharp and SD Slow are similar, but have a lower latency and are minimum phase filters. NOS
is the filter with the lowest steepness and therefore affecting treble more than the others, but
offers the best impulse response.
Mono
OFF, ON, to Left. Default: OFF. The option to Left sends the sum of left and right channel to the
left output only.
Polarity
Inverts the phase (180°) on the corresponding channel.
M/S-Proc
Activates M/S processing. Monaural content is sent to the left, stereo to the right channel.
Loudness
ON, OFF. Default: OFF.
Bass Gain
Maximum Bass amplification. Adjustable from +1 dB to +10 dB in steps of 0.5 dB. Default: +7 dB.
Treble Gain
Max Treble amplification. Adjustable from +1 dB to +10 dB in steps of 0.5 dB. Default: +7 dB.
Low Vol Ref
Reference level for highest Bass/Treble amplification, referenced to the Volume set in dB. Avail-
able range is -90 dB to -20 dB. Default: -30 dB. A volume setting below this point will have maxi-
mum Bass/Treble gain, all volume settings above this point will have lower Bass/Treble gain. 20
dB above the Low Vol Ref setting the Bass/Treble gain will be zero.
Digital DC Protection
ON, OFF, Filter. Default: Filter. ON detects DC in the source signal and mutes the corresponding
analog output if DC is found too high. DC detection stays active with OFF but only issues a dif-
ferent warning message. Filter adds a High Pass to remove DC and infrasound.
De-Emphasis
Auto, OFF, ON. Default: Auto. For manually de-/activating the DAC's de-emphasis filter.
Loopback
OFF, Pre FX to 1/2 –5/6, Post FX to 1/2 –5/6, Post 1/2 –5/6 -6 dB. Routes the current output
signal to the corresponding USB record channels.

8.3 Phones Output, 1/2, 3/4, IEM (all units)
These pages are mostly identical to Line Output. Here are explanations on the differences.
Source
Default: Auto. The source of the output Phones Out 3/4 can be chosen manually anytime. Avail-
able options are: Auto, AES, SPDIF, Analog, USB 1/2, USB 3/4. Auto here not only means current
or available signal, but also channels 1/2.
Rear TRS 3/4 (only Ph 34 on ADI-2/4 Pro SE)
Line 1/2, Phones 3/4. Default: Line 1/2.
The rear TRS outputs can be switched from Line Out 1/2 to Phones 3/4 as source. See block
diagram in the 2/4 Pro manual. The settings of Phones Out 3/4 are then also active for TRS,
including the Ref Level. The Line Ref Level +13 dBu is therefore not available.
The Ref Level of the phones outputs are independently switchable to IEM (+1 dBu), Low Power
(+7 dBu) and High Power (+19 dBu). IEM does not have a Ref Level option (fixed to -3 dBu)

OFF, 30min, 1h, 2h, 4h. The unit checks all outputs for signals
higher than -70 dBFS. With no signal and user action detected
within the set time the unit will enter standby mode.
DSD Detection
Default: ON. Option to deactivate the automatic DSD detection
on SPDIF, AES and USB.
Dig. Out Source
Default, Main Out. Copies the signal of signal path 1/2 (including EQ and volume) to the digital
outputs AES and SPDIF/ADAT. Useful when connecting active monitors with digital inputs.
Note on changing the CC-Mode
The modes Stereo and Multi-channel can only be changed directly at the unit!
The ADI-2 series supports two Class Compliant modes: 2 channel I/O, which allows to use sample
rates up to 768 kHz even with iOS devices, and 6/8 channel mode to give access to all I/Os
simultaneously. In multi-channel mode the sample rate is limited to 192 kHz. To be able to change
the mode USB must be disconnected.

8.4.2 Phones
Dual Phones
OFF, ON. Default: OFF. With Dual Phones ON the phones
output PH 1/2 will be active. Default state is Off, as PH 3/4
is the main phones output and should be used exclusively
unless two phones are to be connected.
If Dual Phones is on and two phones are plugged in, a push
on VOLUME toggles between 1/2, 3/4 and linked volume
control (with the marker over both). When VOLUME is
turned the Dual Volume screen is shown then.
Bal TRS Phones Mode
OFF, ON, Auto. Default: OFF. In Balanced Phones mode output PH 3/4 carries the left channel,
output PH 1/2 the right channel. When Auto is selected, the balanced phones mode is automati-
cally activated as soon as both Phones outputs detect a connector being plugged in. These set-
tings are not valid for the Pentaconn jack, which automatically activates Balanced mode.
Toggle Ph/Line
OFF, 1/2, 3/4, 1/2+3/4, All Plugged, Line/Digital. Default: OFF. Activates the ability to toggle mute
between Phones Out, rear Line Out and digital outputs. Pushing the VOLUME knob for half a
second will then switch between loudspeakers connected to the rear and phones plugged into the
front. All Plugged only incorporates the phones output where a plug is detected. Line/Digital
switches between analog Line Out and digital outputs, with Mute v. Ph active also between
Phones and digital outputs.
Mute v. Ph 1/2
ON, OFF. Default: ON, but grayed out. As soon as a plug is detected in PH 1/2 the rear outputs
1/2 are muted. Note: This function requires Dual Phones to be ON to become accessible. With
Mute v. Ph 1/2 ON the channels Phones 1/2 and Line Out 1/2 have separated settings. Although
both outputs alternately play back the same signal, all settings (Settings, EQ, BT) can be different,
and are separately stored in the background.
Mute v. Ph 3/4
ON, OFF. Default: ON. If set to ON a plug detected in PH 3/4 mutes the rear outputs 1/2.
8.4.3 Clock Settings
Clock Source
Choices are Auto, INT (Internal, Master), AES, SPDIF. Not available in DAC mode.
Sample Rate
This setting can only be changed
when not connected to USB. Oth-
erwise it only serves as info
panel. Choices are 44.1, 48, 88.2,
96, 176.4, 192, 352.8, 384, 705.6
and 768 kHz.

8.4.4 Hardware
SPDIF In
Available settings are: Auto, Coax, Optical. Default: Auto.
SRC (Sample Rate Converter)
Available settings are: Off, AESIn, SPDIF In. Default: SPDIF In. Note: In case a DoP signal (DSD)
is detected, SRC is automatically switched off.
SRC Gain
Available settings: 0 dB, -3 dB. Default: 0 dB. The SRC uses digital headroom to handle inter-
sample peaks up to +3 dBFS without distortion. With the -3 dB setting, an SRC signal with up to
+3 dBFS can be recorded via USB without distortion, or passed on at the AES/SPDIF output in
Dig Thru mode. A normal SRC input signal with 0 dBFS then has a level of -3 dBFS for these two
paths.
Optical Out
Available settings are: SPDIF, ADAT. While the input adapts to the received signal automatically,
the output needs to be switched manually. In Dig Thru mode with an ADAT signal received, the
output is switched to ADAT automatically with all 8 input channels passed through.
Remap Keys
OFF, ON, Remote. Default: Re-
mote. Allows to assign up to 64
different functions/actions to the
four function keys on the device
and seven programmable keys
on the remote, configurable via
the following seven entries:
VOL Key, I/O Key, EQ Key, SETUP Key, I(nfra-red) R(emote) Key 5-7.
Available functions/actions:
Setup 1 to 9, Mono 1/2, Mono 3/4, Mono 1/2 to L, Mono 3/4 to L, Mute 1/2, Mute 3/4, Mute all,
Loudness 1/2, Loudness 3/4, EQ In 1/2, EQ Out 1/2, EQ Out 3/4, B/T Out 1/2, B/T Out 3/4,
EQ+B/T+Ld 1/2, EQ+B/T+Ld 3/4, Toggle Ph/Line, EQ+B/T+Ld 1-4, Polarity, Crossfeed 1-5, DA
SD Sharp, DA SD Slow, DA Sharp, DA Slow, DA SD LD, DA Brickwall, DA NOS, Toggle View,
DIM, Mono all, Mono all to L, Loudness all, EQ Out all, BT all, AutoDark, EQ Preset 1-9, RIAA
Mode +, RIAA Mode -, RIAA Mono B.
Additionally Source AES, Source SPDIF c, Source Optical, Source Analog, Source USB 1/2 are
available. In Basic Mode DAC - and only there - these realize a switching of the input to be mon-
itored on the device and via the remote control.

8.4.5 Display
Lock UI
OFF, Remote, Keys, Keys+Remote. Locks the keys on the device (Keys), the remote control
(Remote) or both (Keys+Remote). Only VOLUME remains operable. To unlock, press and hold
encoder 1.
Mode
Available settings are: Default,
Dark. The dark scheme inverts
the white background and black
numbers/text on the display to
black background and light-grey
numbers/text.
Meter Color
Green, Cyan, Amber, Monochrome, Orange, Red. Default: Cyan. Color of the level meters for
PCM and DSD mode.
Horizontal Meter
The horizontal stereo level meter below the Analyzer can show the peak level before all DSP
processing (Pre, equals the current input level from USB playback and SPDIF In), after all pro-
cessing including volume control (Post), or both at the same time (Dual, default). The outer thin
line is the Pre level. In Dual mode the peak values to the right refer to Post level. Post FX dBu
shows numerical values referenced to dBu.
AutoDark
OFF, ON. Automatically turns off all LEDs and the display (exception: Standby button) after 10
seconds of user inactivity. A key press and turning an encoder will temporarily activate LEDs and
display again. Info and warning messages are shown for 3 seconds.
Volume Screen
ON, OFF. Default: ON. When turning the VOLUME knob at the device the Volume screen is
shown.
8.4.6 Setups
This section allows to save the whole state of the unit as Setup in 9 memory slots. The EQ Presets
are not included, but stored separately. The current state of the EQ is stored, and written to the
EQ memory slot Manual during load of a Setup.
It should be noted that Setup files (!) can have individual, different sets of 20 PEQ Presets. The
nine Setups in the unit however share the same 20 PEQs.
Load Volume with Setup
On, Off, default Off. Setups can
be loaded with or without loading
the volume setting stored in the
Setup. Selecting Off the current
volume will not be changed.
Load
To load one of the nine Setups, click the Load button, then the desired Setup. The circle left to
the Setup name will change from white to orange color to signal the currently active Setup. Any
parameter change will let the circle become grey. This serves as indicator that the current state
no longer equals the stored Setup.

18
User’s Guide ADI-2 Remote - v 1.0
Save
To save the current state click the Save button, then click the desired Setup button. The circle
left to the Setup name will change from white to orange color.
Factory
To load a factory Setup click Load, then Factory. This is an additional, internal and fixed Setup
(unlisted Setup number 10 if you will) that includes typical default settings. The Factory setup
changes all kinds of settings, but does not alter the current EQ or EQ Presets values. Only the
choice of currently active EQ might be changed.
8.5 EQ Presets (PEQ Editor)
8.5.1 EQ Preset Editor
Listen
The EQ Preset Editor gives access to the 20 EQs stored in the device, without overwriting them
immediately after applying changes. In fact the Editor can also be used offline to load, edit and
save EQ Presets.
The button Listen temporarily
loads the current EQ Preset into
the active output.
File –Load
A click on Load brings up a file selection dialog, prefiltered for .adieqpr files.
File –Save
A click on Save brings up a file selection dialog to save the current EQ as .adieqpr file.
Clear
Similar to the Preset Clear within the unit this button sets the EQ to linear or flat frequency re-
sponse.
8.5.2 EQ Presets
Device: Store
Clicking Store the currently active EQ is stored to the device, on the same Preset number.
Device: Re-Load
Any EQ Preset in the device can easily be loaded into the EQ Preset Editor by clicking Re-Load.
This is also helpful to undo any changes that were done in the EQ Preset Editor, but not yet
transferred into the device.
States of EQ Presets
Selecting any of the 20 EQ Pre-
sets the circle left to the Preset
name will change from white to
orange color to signal the cur-
rently active Preset. Any parame-
ter change will let the Preset
number change from white to or-
ange. This serves as indicator
that the current state no longer
equals the stored Preset. Select-
ing a different EQ Preset the or-
ange number will stay visible as a
reminder.
On exit of the app a dialog will ask for confirmation if these changes should be discarded.

Copy / Paste
While the unit includes a feature to swap EQ Presets, easily changing their order, the app cur-
rently needs the older Copy and Paste scheme to do the same:
- Select any EQ Preset (for example 1), click Copy
- Select any other EQ Preset (for example 2), click Paste. The EQ settings of EQ Preset 1, includ-
ing the Preset name, are now copied to EQ Preset 2.
- To swap EQ Presets or to change their order: copy the EQ Preset (1) onto an empty Preset (for
example 18), copy Preset 2 to 1, then 18 to 2. Now EQ Preset 1 and 2 are swapped.
