SDM16i Product Manual
Overview:
1. Inputs 1 to 2 - Combo XLR / ¼” TS Jack - Hi-Z (¼”), Balanced (XLR)
The first channels have Hi-Z ¼” inputs designed for connecting guitars directly with a guitar
lead. Ideal for electric-acoustic guitars and bass. The XLR input can also be used instead, for
extra microphone channels.
1A. Inputs 3 to 16 - Combo XLR / ¼” TRS Jack - Balanced
The remaining channels from 3 to 16 all feature a Line Level ¼” TRS jack inputs designed for
connecting any line level signal such as outputs from keyboards, electronic drum machines,
DJ mixers, CD players etc. Again, the

The 4 individual balanced XLR line level AUX outputs allow for separate mixes to be created

and often sent to foldback speakers, and used to send separate mix and crossover EQ setting
to subwoofers. Select Pre or Post fader and apply parametric EQ and compression/limiting for
each AUX channel.
3. Main Outputs - XLR and ¼” TRS
Featuring balanced line level XLR and TRS output connection options, both outputting the
main left and right channel signal. Connect these to your FOH (front of house), full range
speakers. Use parametric EQ to tweak the final output to suit the room, and add hard
compression as a form of a limiter to squash peaking signals.
4. Main Output Volume Control
Set the main output to the unity setting at 1 o’clock, or tweak to suit your speaker system or
venue. Also maintains a hands-on option to control the main output if required.
5. Headphone Amplifier and Volume Control
Connect any headphones into the headphone amplifier ¼” TRS output to monitor the main
output, or change settings to monitor Solo mode selected channels and even FX wet signals so
you can get than reverb setting perfect. Utilising Solo functionality, the headphone channel
can also be used as an additional AUX output, but be mindful to setup the headphone output
as to not overload a line level input (i.e. usually a 2 o’clock setting is enough).
6. LED Meter Strip
Clearly lit LED lights flash to indicate signal level for the main output. With LED 11 frequency
levels going up to +10dB. Will display the same as the main output within the software.
7. Wireless and Wired Connectivity
Flick between using the in-built W-Fi hotspot or use an Ethernet cable to connect to an
external router, existing network or seperate hotspot device. The plug and play ability of the
Wi-Fi hotspot, with reliable range of 20m is great for on stage performers and small venues.
Larger venues and live mixing engineers should consider connecting to existing networks or
network extenders with a wider Wi-Fi range. A device connected to a router via ethernet also
gives a completely wired connection that eliminates any potential for any software dropouts.
8. USB Port for Playback and Stereo Recording
A USB stick or flash drive can be connected to either playback music into the individual player
channel of the mixer, or record the main left and right signal from the mixer. Also very useful
when mixing yourself as a performer, as you can for example record a take of verse and then
move into the audience area and playback the recording to hear the mix and even make
EQ/compression adjustments in the player channel to tweak the sound live, which you can
then replicate on the appropriate channels.
9. SPDIF Digital Audio Input and Output
Interface with any digital device that has SPDIF input/outputs. The SPDIF input has its only
channel within the mixer software, again with EQ, compressor setting options. The SPDIF
3
SDM16i Product Manual
output is of the main left/right channels.
10. Antenna
A fixed antenna that can we raised when in being used in Wi-Fi mode or collapsed and locked
in when not in use.
11. 48V Phantom Power LED
Indicates that 48V phantom power has been selected for at least one of the channels. A clear
icon also displays on each channel in the software when phantom power is selected.
Hookup Example:
1. Wired or Wireless - Ethernet Connection via Router
Connect an ethernet/network cable to your router to enable control of mixer from any device
4
SDM16i Product Manual
connected to the router’s Wi-Fi, including both wired and wireless hotspot connections. The
SDM16i software runs on HTML5 is accessible through any modern browser. User maintains
access to the internet connection of the router.
2. Wireless Wi-Fi Hotspot Connection
Switching to WiFi mode turns on the inbuilt Wi-Fi router hotspot inside the unit, enabling any
Wi-Fi enabled device to connect to the mixer wirelessly, without the need for an external
router.
3. Hi-Z Instrument Inputs
Channels 1 and 2 feature Hi-Z / high impedance inputs on the ¼” jacks, acting like an in-built
DI box, allowing direct connection of guitars and instruments with hi-z pickups. Suited for
connecting acoustic/electric and bass guitars, though just like for DI’s be mindful to turn your
instrument volume down from 10, to ensure you are not overloading the input, especially for
active bass guitars.
4. Electric Guitar with Amplifier Mic
While the electric guitar could be plugged in directly to the Hi-Z inputs on channels 1/2, a
better way to capture the sound of your sound for mixing through the PA, is to mic up the
guitar amp to capture the full sound of your rig. Using an instrument mic like the iSK DM-57 is
a great option.
5. Keyboard via DI Box or Direct ¼” Connection
The combo jacks of channels 3 to 16 feature ¼” TRS line level inputs, suitable for connecting
most keyboards via their ¼” jack outputs. However, due to a keyboard’s connection to 240V
wall power, ground hums can arise especially if the mixer and keyboard are connected to
different power circuits. By using a passive DI box such as the SWAMP DB-1, a transformer is
adding to the signal removing ground loops while also converting the signal to balanced, mic
level for input into the mixer using XLR cables.
6. DJ Mixer - ¼” Line Level Inputs
The line level outputs of DJ mixing desks, either RCA, ¼” or XLR, can be connected directly into
the balanced ¼” TRS inputs (sitting in the middle of each combo XLR/Jack connector). Any
device outputting a line level signal can be connected in this way. Utilise our wide range of ¼”
TRS to RCA/XLR/Jack linking and patch cables. Pan the channels left and right respectively, to
get true stereo sound.
7. Mic Up Drum Kits
With 16 channels, each with a mic preamp, there is no excuse not to mic up the drum kit.
In-built dynamics and EQ on each channel allows for detailed mixing and you can save the
scene once setup, so consider a full mic setup. Each channel as 48V phantom power for
overhead condensers.
8. Headphone Monitoring
With a physical volume control, use to monitor your signals before sending them through the
5
SDM16i Product Manual
main outputs. Using the solo functionality allows for monitors of individual channels, or
groups of selected channels. Can also be used as additional output if required, though turn
down output volume to 3 o’clock if connecting to line inputs on speakers.
9. Smartphone / Laptop Audio Playback
Plug in any smartphone, tablet, laptop or any device with a 3.5mm headphone output. Using a
3.5mm TRS to dual ¼” cable a user can connect to 2 channels and by panning each left and
right in the software a true stereo input is created.
10. Foldback Monitors and FOH Speakers
Connect your FOH (Front of House) speakers to the Main left and right outputs. Balanced XLR
and ¼” TRS outputs are given, wired in parallel, allowing using to the connector of preference.
The extra output enables the main signal to be sent to additional speakers or devices. Each of
the 4 AUX balanced XLR outputs carry signals that can have uniquely mixed signals sent to
foldback monitors or in-ear systems. Use balanced inputs on your speaker where possible for
a balanced signal connection to avoid noise picked up along the cable for mixer to speaker.
11. Microphones
Vocal microphones can be connected to any channel from 1 to 16, dynamic and condenser
microphones are supported with 48V phantom power on each channel.
Control Software:
Utilising HTML5 technology, any device with a modern web browser can use the SDM16i control
software. That means and smartphones, tablet, laptop or desktop, whether they are Windows, MAC or
Linux, all simultaneously with up to 10 users at a time.
Requiring no app to download or install, the software is reliable, highly stable due with no app that
can crash. If you close the browser manually or it happened to close unexpectedly, the mixer will
continue to operate with its prior settings to the interface page being closed.
Access to mixer control page is through a simple URL that is first loaded through a fixed IP Address,
and be latter recalled in your browser by typing any part of ‘WIFI-MIX’ into the URL bar, or simply save
a bookmark link.

acts, to give some consistency to sound and prevent musicians from playing too loudly of harshly.
