1 - In roduc ion
The 8816 is an extremely versatile 16:2 summing mixer, which can
produce the highest possible recording and mixing performances in any
format using revered Neve analogue designs including transformer
mixing.
With comprehensive input, mixing and monitoring functions, 8816 can
upgrade a DAW to a professional mixing facility. Not only does the unit
provide quite unbelievable analogue facilities but also has remix and
Recall as standard.
In addition to the superb facilities offered as standard on the 8816
there are two options, digital outputs and a fader pack.
ADC Ou pu
World class A to Ds with sampling rates of up to 192kHz and DSD
outputs. Analogue insert points are provided ahead of the ADCs that
couple the ultimate analogue circuitry with superior digital conversion
making the unit an obvious choice for complete integration with a
DAW.
NOTE: Requires internal fitting, please onsult your lo al Neve dealer.
Fader Pack
16 Input Faders with Cut / Solo controls and post fade direct outputs
plus 2 Master Faders give the engineer fine level control with a
traditional feel. With the fader unit attached, the rotary channel level
controls become aux send levels increasing the functionality of the
unit.
No e on Headroom and Levels
•Each channel has 15dB of gain also known as 15dB 'in hand'.
•Excessive use of gain may overload your DAW or other
recording device. 0dB on the channel level control is approx at
the 12’o’clock position.
•Internal headroom is 26dBu.
•If your DAW is overloading but the overload indicators on the
8816 meters are N T illuminated then back off your output
levels.
•If your DAW is overloading and the red overload indicators ARE
illuminated then you may need to back off your input levels.

2 - Applica ion Scenarios
Recording
The 8816 can be used to monitor from the workstation while recording
directly from a mic pre such as the 1073DPD or as a pre-mixer for
recording a number of signals simultaneously to the workstation.
With the optional fader pack, direct outs can be used from the 8816 to
the DAW enabling it to be used like a conventional desk with both
recording and monitoring signals passing through the unit.
Direc recording wi h 8816 as moni or
Connect the output of the mic pre to the input of the workstation.
Connect the outputs of the workstation to the inputs of the 8816. The
8816 outputs can be monitored on loudspeakers or headphones as
required. The performers headphones source can be switched
(engineer/performer).
Sub-mixing signals o be recorded
Connect the instruments to be recorded to the inputs of the 8816 (via
a 1073 or similar mic pre if required). Connect the main output of the
8816 to the inputs of the workstation (this can be analogue or digital if
the optional digital card is fitted).
Set the balance required using the channel level controls on the 8816
and record onto the workstation.
- Page 6 -

88 Series Outboard / 8816 Summing Mixer Issue 5
Recording wi h op ional Fader Pack
Connect the instruments to be recorded to channel inputs on the 8816
and connect the direct outputs from these channels to the inputs of the
DAW (the direct outs are located on the fader pack).
These channels can be muted so that they do not go to the main bus if
monitoring via the 8816 or a monitor mix can be set up on the DAW
and monitored via the 2 Track Re urn on the 8816.
Signals can now be recorded with fader control over their level while
the mix or play back is monitored through the 8816.
In all of the above recording situations the engineer can utilise the
8816 to control monitoring via two pairs of speakers and/or the
headphones as required.
The 8816 can also be used to provide a Cue to performer headphones.
- Page 7 -

88 Series Outboard / 8816 Summing Mixer Issue 5
Overdubbing
Connect the outputs of the workstation to the inputs of the 8816. If
you have a backing track pre-mix on your workstation assign this to
outputs connected to inputs 15/16 on the 8816.
Connect the output of the track being recorded to any of inputs 1-14
on the 8816.
Connect the performer’s headphones to the headphone socket on the
rear of the 8816.
The cue mix level of the overdub against the backing track can be
adjusted using the Cue level control until the mix is right for the
performer.
The 2-Track Re urn can also be routed to the Cue so may be used as
an effects return if the performer wishes to listen to a guide reverb
while recording.
The engineer can monitor on headphones connected to the front of the
8816 and can switch between monitoring the performer’s cue mix and
the main mix.
- Page 8 -

88 Series Outboard / 8816 Summing Mixer Issue 5
Mixing
Connect the outputs of the workstation to the inputs of the 8816. Key
elements such as lead vocals and lead instruments should be kept
separate within the workstation and connected to individual inputs on
the 8816. ther elements such as backing vocals, effects, etc can be
routed to stereo groups within the workstation and these groups
connected to the 8816 inputs.
ptimum sound quality within the workstation is generally achieved by
setting the virtual faders to 0dB. Final mix levels can be set on the
8816.
The mix is now being created on the mix bus of the 8816. This uses
the same transformer mix topology as the classic 80 series Neve
consoles and recreates their legendary sound. Recording back to the
DAW or onto another device such as a CDR may be analogue or, if the
digital option is fitted, can be from the Neve Analogue to Digital
Converters ensuring the best possible sound quality.
A Neve 33609 compressor or a Neve 8803 EQ unit can be patched
across the Insert allowing the whole mix to be compressed or EQ’d.
Sometimes it is necessary to mix between a clean mix and a processed
mix, for example when using a Filter Bank to create a special effect
across the whole mix for one section of a song. This can be done by
patching the filter bank across the Inserts of the 8816 and switching to
Inser Mix mode.
The balance between the clean mix and the processed mix is now
controlled by the Inser Mix level control and the engineer can switch
between clean and processed mix or balance the two as required.
- Page 9 -

88 Series Outboard / 8816 Summing Mixer Issue 5
Mixing wi h Fader Pack
The engineer and producer can monitor on two sets of speakers, main
and near field, and switch between them using the Al Speaker switch
allowing comparisons of the mix on small and large speakers.
Headphones can also be connected if required.
The outputs of the recording unit (or the appropriate two tracks of the
DAW) can be connected to the two track return so that the engineer
can switch between monitoring the mix leaving the 8816 and the mix
coming back from the recorder.
- Page 10 -

88 Series Outboard / 8816 Summing Mixer Issue 5
Mas ering
Connect the outputs of your DAT, CD player or two tracks of your DAW
to inputs 1 and 2 on the 8816. Connect the master outputs of the 8816
to the inputs of the Workstation, CDR or DAT that you wish to record
onto.
Connect the outputs of the recording device to the 2 track return of the
8816.
The mix is now passing through the mix bus of the 8816.
A Neve 33609 compressor or a Neve 8803 EQ unit can be patched
across the Insert Point allowing the whole mix to be compressed or
EQ’d.
The Insert can be switched to Sum and Difference mode allowing the
producer to process the centre sum/mono signal and the
stereo/difference signal in different manners. The width control can be
used to reduce the stereo width, perhaps for a club remix, or to
enhance it beyond standard stereo if the original mix is not wide
enough.
The engineer and producer can monitor on two sets of speakers, and
switch between them using the Al Speaker switch allowing
comparisons of the mastered mix on small and large speakers.
Headphones can also be connected if required.
The monitor source select can be used to switch between monitoring
the sound entering the 8816 on inputs 1 and 2, the sound leaving the
8816 on the mix bus and the sound as recorded on the
CDR/DAT/Workstation via the 2 Track Re urn.
- Page 11 -

88 Series Outboard / 8816 Summing Mixer Issue 5
Live Recording
While the output for the main Front f House console may be of a high
standard, the mix created for the venue does not have the correct
balance for the recording. The 8816 can solve this problem.
The main mix outputs of the 8816 should be connected to a recording
device such as a DAT or DAW running on a laptop Mac or PC. The
output of the recording device should be connected to the 2 Track
Re urn on the 8816.
Key elements such as the lead vocal can be connected directly to an
input on the 8816 from a Direct ut on the F H console. ther
elements such as drums, keyboards, etc can be connected to the
inputs of the 8816 either from the Group utputs or from the Matrix
utputs of the F H console depending on the type of F H console
being used.
A correct balance between the individual and pre-mixed sounds can be
set up on the 8816 using the Channel level controls. The mix is now
passing through the mix bus of the 8816.
The engineer can monitor the live recording on headphones and switch
between monitoring the output of the 8816 and the 2 Track Re urn
from the recorder for a confidence check on the recorded sound.
- Page 12 -

88 Series Outboard / 8816 Summing Mixer Issue 5
Sub Mixer
Sometime the console being used for a mix simply does not have
enough inputs. This may be because it is a small digital mixer being
used to meet a fixed budget or because the console has a limited
number of inputs.
Connect the outputs of the additional instruments or sound sources
such as keyboards, effects units etc to the inputs of the 8816. Connect
the Main Ou pu s of the 8816 to a pair of inputs on the main mixer.
The sounds passing through the 8816 can be balanced using the
Channel Level controls. These sounds are now passing through the
mix bus of the 8816.
The overall level being passed to the main mixer can be set using the
Mas er Level control of the 8816.
Should more than 16 inputs be required on the sub-mixer then two
8816 units can be used. The output from the first 8816 is connected to
the 2 Track Bus Inpu of the second 8816 and the Main Ou pu from
the second 8816 goes to the main mixer.

88 Series Outboard / 8816 Summing Mixer Issue 5
3 - Con rols
Channel S rip
The channel strip comprises a Cu /Solo button, a rotary Level
control, a rotary Pan control and a Cue select button.
Level Con rol
The Level Control has a range of ∞dB to +15dB with 0dB set at about
12 o'clock. This range is deliberately chosen to be able to
accommodate most line inputs levels whether they be professional
+4dBu inputs or semi-professional -10dBV inputs. The Level control
sets the levels going to the main L+R Mix Ou pu s and to the U ili y
Aux Bus with the extra benefit of changing its function into an
individual aux bus send level when an optional fader panel is fitted.
Pan Con rol
This is a classic -3dB centre pan, with S-Law shaping to help accurate
panning to extremes of left and right.
Cue Con rol Bu on
When operated this takes the input of the channel (pre level and pre
pan) and sends it to the cue mixer via the cue level control to feed the
cue output to headphones. Channels 1-14 are individually switchable to
the cue via the Cue level control. Channels 15 and 16 are linked as a
stereo cue direct to the cue mix. For overdubbing, channels 15-16 can
be set up as your backing track mix on the DAW, and then selecting
the appropriate channel from 1 to 14 will allow you to blend or ride a
track using the cue level control, allowing the artist to hear exactly
what he or she needs to hear before dropping in to record.
Channel Cu /Solo bu on
The function of the button can be changed from Cu to Solo by
operating the Solo Mas er adjacent to channel 16.
In Cu mode this button will mute the feed to the main two track bus.
Cu is indicated by the button turning red.
In Solo mode, selecting the button will cut all channels except the one
operated, commonly referred to as Solo In Place.
Solo is indicated by the button turning yellow.
As the solo system is latching, it is possible to build up solo groups and
to then use the Cu /Solo Mas er to audition a solo group or a cut
group.
This can be useful for comping or sorting out EQ / balance problems in
the mix quickly before printing the final pass.

88 Series Outboard / 8816 Summing Mixer Issue 5
Cue Sec ion
2T o Cue
Sends the 2 Track Re urn (post level control) to the headphone mix –
ideally suited for replaying the last overdub to the artist for auditioning
or a complete 2 track mix of the whole song without the artist needing
to come into the control room.
Headphone Mon
Selects the prefade LS Ou pu s onto the Cue headphone outputs so
the artist hears the same sources as the engineer feeds to the
monitors.
Headphone Con rol
This control adjusts the main Headphone levels with a range of ∞dB -
0dB.
The headphone control also incorporates a switch which, when
operated, feeds the unit's talkback mic to the Headphone Ou pu ,
automatically dimming the music fed to the headphones and
loudspeakers.
There is also a parallel 1/4 inch jack on the rear of the unit for
footswitch operation.
Headphone Jack
A headphone jack is provided on the front of the unit and a second
parallel headphone jack on the rear.
Parallel +4dBu line outputs are provided on the rear of the unit to be
used for Cue feeds to the studio.
NOTE: Only headphones with impedan es above 60 Ohms should be used.
- Page 15 -

88 Series Outboard / 8816 Summing Mixer Issue 5
4 - Mas er Sec ion
Al Spk
Selects a second set of loudspeakers for switching between main and
near field loud speakers.
iMon
This input has a 3.5mm jack socket for connecting your iPod or other
MP3 player to the unit’s LS selector and feeding to the LS Ou pu or
Cue headphone outputs.
Talkback Level
This adjustment screw sets the level from the talkback mic to the cue
headphones. This is performed when setting up the unit, so talkback is
at a set level during a session.
Talkback Microphone
A microphone is built into the unit to allow the engineer or producer to
communicate with the artist during recording sessions.
INS MIX
Inser Mix routes the IMR signal to the main 2 Track Mix Ou pu
pre-level control but post-inser .
IMR Level Con rol
Inser Mix Re urn allows for the IMR signals to be mixed directly into
the main mix output, post insert but pre mix output level control. It
has a range of ∞dB to +10dB and can be used for DJ style mixing or
where the engineer wants to mix some compressed or EQ’d main mix
source back into the main mix outputs without the compression or EQ
dominating the mix as it would using the insert.
INS
This switches the main mix pre fade insert in and out of circuit via the
input and output connectors on the rear of the unit.
It has two modes selectable by pressing the Mix Level control. When a
normal pre fade insert is selected the button will illuminate yellow.
If the mix level control is pressed then the illumination will change to
red indicating that the insert point has changed to a Sum &
Difference insert.
In Sum and Difference mode the standard stereo signal is converted
into a mono common or sum signal on the left output and a mono
difference signal on the right output.
This enables the engineer to apply different processes to the common
(or centre) image and the difference (or stereo) image.
At the insert return the signal is re-converted to a standard stereo
signal.
The technique is frequently used in mastering recordings and is useful
for:
•Using an overall stereo EQ where the L & R Image will not shift
with any tracking errors within the EQ unit, or EQ the mono to
subtly change the mix balance post mixing.
•Compress and limit the Sum and Difference separately to
negate tracking errors or create a quite different stereo image.
•Add a sub bass synth to the mono program for really deep
mono bass that will not make the cutter head jump if
mastering to vinyl.
- Page 16 -

88 Series Outboard / 8816 Summing Mixer Issue 5
•Listen to the mono and trim the DAW sample delays to get
perfect L & R tracking and save the results to an interleaved
wav file.
•A vocal could be brightened by EQing the Sum signal or
Cymbals could be brightened by EQing the Difference signal.
N.B. The underlying mode of the insert an be hanged by pressing the Mix level ontrol even if the
insertion button is not sele ted.
2TR MIX
When selected, sends the 2 track return signal directly to the 2 Track
Mix bus.
2TR Level Con rol
This adjusts the two track return level sent to the Cue Mix or 2 Track
Mix bus and has a range of ∞dB to +10dB. This is useful for sending 2
track mixes to the cue headphones or as a reverb return to the cues or
2 track mix bus.
Moni or Selec ions
There are 3 leds above the Mon level control that indicate what is
selected to the LS monitor.
If no led is illuminated then the main monitor defaults to the main mix
output. Selection of the sources to the monitor is by pressing the Mon
level control.
•1st press: selects 2TR to Mon
•2nd press: selects CH1/2 pre fade sources
•3rd press: selects iMon input
•4th press: returns the monitor to the Main Mix output.
It is also possible to set the main mix source to the monitors post the
ADC insert jack (if fitted), which will allow for monitoring of the main
mix signal or the inserted signal.
This could be of benefit when you need to monitor the ADC Input which
could be a completely different source from the 8816 such as when
using the digital option as a separate high quality stereo A to D.
NOTE: The monitor sour e an be set to pre or post ADC insert using jumpers within the unit.
Information is provided in the Jumper Settings se tion.
Mon Level
This alters the loud speaker’s output level and has a range of ∞dB to
0dB.
Sum
This is selected by pressing the width control. When illuminated yellow
then the main mix outputs are summed with whatever is selected to
the LS Moni or. This function is useful when auditioning mixes
together in the Main or Al loudspeakers.
Wid h Con rol
The Width control is post mix level control, and alters the stereo image
from mono through stereo to enhanced stereo.
<W> bu on
This switches the Wid h control into circuit across the Main mix output
(post insert) and is indicated by the button being illuminated yellow.
- Page 17 -

88 Series Outboard / 8816 Summing Mixer Issue 5
Mix Level
This alters the main mix level and has a range of ∞dB to 0dB. It can be
used to control the output level from the unit to the DAW.
The control can also be augmented with fader control if an optional
fader pack is fitted. In this case, the mix level control no longer has
any function.
Analogue / Digi al overload indica ion
Analogue overload of the unit is indicated by a red led in the associated
left or right output meter. The actual level at which the overload led
illuminates is about 1dB below the max output of the unit (+26 dBu).
If the ADC option is fitted to the unit then the led will light yellow if a
digital overload occurs for more than 1 sample. This has priority over
the analogue overload indication. Sensitivity of the digital overload
indication will be set by the unit’s digital operating level.
Me ering
The main left and right meters are sourced directly from the main
outputs so signal problems within the unit or what is connected can be
metered correctly. The meter is a pseudo PPM type with a special scale
that ranges from -16 to +26 dBu. This type of meter and range is ideal
for accurate metering of analogue levels when they are fed to a digital
recorder to maximise levels and to avoid digital clipping. Three
important points are identified on the meter to help the user to match
levels between the unit and a DAW.
•0 (PPM Scale Point 5) for line-up +4dBu (0vu)
•14 (PPM Scale Point 8.5) +18 dBu for typical DAWs set to 14 = 0dBFS, REL +4 dBu.
•18 (PPM Scale Point 9.5) +22 dBu for typical DAWs set to 18 = 0dBFS, REL +4 dBu.
Power Swi ch
Switches the unit on/off and indicates a healthy +36 volts supply by
illuminating red.

88 Series Outboard / 8816 Summing Mixer Issue 5
5 - Op ions
Fader Pack Op ion
The optional fader pack provides 16 Input faders with post fade direct
outputs plus mutes and 2 Mas er faders.
The Inpu faders have a range of -∞dB to +15 dB.
The Mas er faders have a range of -∞dB to 0dB.
With the fader pack fitted, the rotary channel level control of the 8816
becomes an aux send level control with a range of -∞dB to +15dB.
This can be used to send channels to a reverb or other effects unit.
Recall of the faders and mutes can be stored using USB and the Recall
application so that they can be included into the multi- unit Recall
system provided on the 88 outboard range.
NOTE: Internal jumper settings must be hanged to enable the optional fader pa k to take ontrol of the
main mix level. See se tion on Jumper settings.
•When the fader option is not fitted, the jumper sets the Aux output level to –3dBu.
•When the fader option is fitted, the jumper sets the Aux output level to 0dBu
ADC Op ion
Sampling Frequency
Sample frequency can be selected by pressing the button to the right
of the sample frequency leds. This will toggle through the sampling
frequencies required one at a time.
The 8816 has 2 sync inputs, AES 3 on a female XLR and Word Clock on
a chassis BNC. If neither sync input is present, the unit will synchronise
to its internal crystal clock.
If one or the other sync inputs is present at the correct sampling
frequency the led (AES or WCLK) will illuminate showing that the sync
input is being used as a reference. If both sync inputs are present and
correct the word clock input will be used as the reference.
Normally the sync input is set to the required sample rate. In this case
both AES out 1/L and AES out 2/R carry the same stereo AES signal
converted from the unit’s left and right analogue outputs.
Double Ra e AES Ou pu
It is also possible to select 96kHz (or 88.1kHz) sample rate with a
48kHz (or 44.1kHz) sync input. Similarly it is possible to select 192kHz
(or 176.2 kHz) sample rate with a 96kHz (or 88.1kHz) sync input.
This will cause the unit to output double rate AES on the two AES
utput connectors. The sync led will illuminate green indicating the
sync reference is still being used for the digital output even though the
ADC is sampling at twice the sync input sampling rate.
In this situation AES out 1/L carries the odd and even samples of the
left audio double rate signal on its left and right digital channels
respectively. Similarly, AES out 2/R carries the odd and even samples
of the right audio double rate signal on its left and right AES channels.
DSD
Selecting DSD will default to 44.1kHz reference.
If no sync is available it will use its own internal crystal reference. The
- Page 19 -

88 Series Outboard / 8816 Summing Mixer Issue 5
interface requires a minimum of 2 BNC cables (DSD left and DSD right)
to the DSD recording device. The DSD output is switchable between
SDIF 2 and SDIF 3 with a rear panel switch. SDIF 2 requires a 44.1kHz
sync signal to be passed to the DAC and this should preferably come
from the 8816 sync output via a 3rd BNC cable. SDIF 3 transmits the
DSD signals with clock information included and should not need the
sync signal.
N.B. Refer to your DSD re ording devi e for information on ompatibility.
