Welcome & Thank You
ASP880 | Contents
Thank you for purchasing
this audient product!
ASP880 can be seen as the natural
progression of our classic ASP008
eight channel microphone preamplifier.
Using the same proven discrete class-a
8-transistor input stage with extended
bandwidth and a noise floor close to the
theoretical Johnson noise limit, ASP880
provides a world-class recording front end
in a convenient 1RU package.
The microphone preamplifier has been
refined over 15 years by design legend
David Dearden and is the same tried &
tested topology as featured in our consoles
and recording interfaces (iD22, ASP8024,
ASP4816).
Features include:
• 8 x superb class-a mic preamplifiers & 2
x discrete JFET instrument inputs
• Clean & stable P48 phantom power
• 60dB of clean gain with -10dB pads on
channels 1 & 2 for kick, snare etc
• Polarity reverse to enable phase
coherent recording across all tracks
• Variable input impedance providing a
“triangle-of-tone”. Lo, med and hi settings
allow you to voice your mic collection at
the flip of a switch!

However we did not stop there with ASP880
- after months of refinement and an entirely
new PSU design, we have been able to lower
the noise floor in the unit and have reduced
the 50Hz mains component to vanishingly
low levels and the unit is completely silent
(fanless operation) - impressive!
On top of this we have used the cutting edge
top-of-the-line Burr-Brown converters from
our iD22 interface to heavily upgrade the
digital card which now comes as standard!
The unit is built like a tank and now features
our custom, solid aluminium control knobs
which feel great and provide excellent visual
feedback. ASP880 will last for years to come!
• Super smooth 12dB/octave sweepable
high pass filter (25 to 250Hz) to clean
up low end rumble and mess!
• New A-D insert switch provides line
level direct access to converters for
integrating outboard processing
between the mic pres and ADC
• Integrated Burr-Brown 115dB ADC with
AES and SMUX ADAT outputs
• Integrated fanless, low noise PSU with

Hardware Features
Microphone Preamplifiers
& Line Inputs
ASP880 features eight impeccably
optimised class-a micprohone preamplifiers.
Featuring a discrete 8-transistor front end,
the mic pre is optimised for 0 to 60dB gain
with an EIN (equivalent input noise) of -127.5
dB. The frontend has high-input headroom
and will be happy to accept any level from

(Instrument) Inputs
ASP880 features two discrete class-a JFET

Why JFET?
Junction Field Effect Transistors are known
for their sweet tone and tube-like properties

Setting Levels & Gain
Aim for -10dBFS peaks on the loudest sections
when setting gain & recording levels in the DAW!
Input Conditioning
Hardware Features
1. 2. 3. 4. 5.
ASP880 has plenty of analogue headroom,
running internally on +/-18V DC rails.
The unit can deliver up to +27.5dBu at the
analogue output DB25 on the rear of the
unit.
However it would be typical in modern
digital recording situations that ASP880 is
using our own internal pristine 115dB ADC
converters to produce a digital output for
recording via AES or ADAT digital output.
In this case, the ASP880 has a digital line-
up reference of +18dBu = 0dBFS (full scale),
In order to correctly condition input signals,
ASP880 provides the following functions:
• +48V Phantom Power
• -10dB Pad (channels 1 & 2)
• Polarity Reverse
• Sweepable High Pass FIlter
P48 Phantom Power
Phantom power can be supplied on a per
channel basis by pressing the +48V switch
(1). This is supplied at 48V +/-4v @ 10mA
per channel and is fully compliant with the
DIN45596 specification. This is suitable for
any phantom powered condenser mics, or
To check phase coherency on multi-mic
setups, first always use careful microphone
placement and then press the
on various combinations of channels to find
the fullest, most solid low frequency
representation of the source.
ø switch (3)
therefore the analogue circuitry will have
anywhere from 4 to 9.5dB headroom above
digital maximum (don’t worry about it!).
As a target guide, we would recommend
that you turn up the ASP880 gain pots to
produce a -10dBFS peak signal level in your
DAW when recording. This will maintain
plenty of headroom and things often sound
better in the DAW if you record with lots of
headroom.
To do this, adjust the gain knob on ASP880
whilst observing the metering in your
interface or DAW application.
The LED metering on the ASP880 will show
signal present at -48dBFS (-30dBu), slowly
ramping to -28dBFS (-10dBu) with a peak
LED warning of potential overloads at -2dBFS
(+16dBu). However please rely upon the
ribbons with on-board active head amps etc.
-10dB Pad
The 10dB pad (2) can be used in conjunction
with the gain control to adjust any hot
signals on channels 1 & 2. Please note that
the actual attenuation value of this pad will
vary with micpre input impedance (lo, med or
hi) and therefore using your ears and eyes is
the best policy here!
ø Polarity Reverse
Polarity reverse (180 degrees) can be
applied to any channel to ensure that
multi-mic setups sound as full as possible.
On drum kit recordings typically you may find
either the kick drum out of phase with the
overheads, or the underneath snare mic out
of phase with the top snare mic etc. Some-
times, one overhead is out of phase with the
kick drum, so move mics first and then use
the polarity reverse switch to find the best
compromise.
Sweepable High Pass Filter
The sweepable HPF is 2nd order 12dB per
octave and can be used to increase head-
room and clean up low frequency rumble etc.
Engage this by pressing the switch (4)
recording destination for accurate metering.

Variable Input Impedance
One stand-out feature of the ASP880 is the
variable input impedance (Z) control.
There are three impedance load settings on
the unit, and these can be used to extract
various voicings from your mic collection by
loading the mic’s output stage differently.
Notably mics with transformer outputs such
as SM57 / SM7 dynamic mics or Coles
4038 ribbon microphones often provide
quite noticeable changes in tone when
operated into various loads.
The source (microphone) and load (mic pre-
amplifier) form a bridging voltage divider,
that contain different values of resistance
for the source at different frequencies - thus
creating a varying frequency response (or
different output levels for each part of the
SM57 impedance curve) and thus a change
in tone can be perceived.

2. Change in Speed (Transient Response)
3. Change in Tone (Frequency Response)
4. Change in Detail
Please be aware that some microphone
types (transformerless condensor types)
may not produce audible changes due to
their electronically buffered output stages
which have linear output impedances with
regards to frequency and therefore are less
susceptible to changes in loading.
If in doubt, consult your microphone
datasheet & manufacturer.

• LO 220Ω
• MED 1200Ω
• HI 2800Ω

SM57 for example (illustration only):

Typically there is some change in level,

Digital Outputs - AES - S/PDIF
ASP880 features 8 analogue, cross-coupled
line driver outputs on DB25. These fully
balanced outputs use the same circuitry
as our proven ASP8024 flagship console
and provide “transformer-like” differential
line drive and high headroom with a sturdy,
transparent pair of operational amplfiiers.
Use these outputs to use ASP880 as a
standalone eight channel analogue mic pre.
These outputs are wired as Tascam DB25
standardwith100Ωoutputimpedanceand

The on-board digital card in ASP880 can
provide both double speed (96kHz) AES
and ADAT output signals.
The AES output is available on a 9-pin DSUB
connector and is fully transformer balanced
according the AES specification. The 9-pin
DB9 connector provides eight channels of
balanced AES digital output and the wiring
pinout is as shown to the right.
Pressing the AES - S/PDIF switch (1) will
switch the DB9 output stage into consumer
format (lower signal amplitude etc) for
S/PDIF operation. In most cases, you will
AD Converter Direct Access / Inserts
ADC balanced line inputs are available on a
rear panel DB25 connector (also Tascam
format). You can use these to directly
access the AD converter with +18dBu input
headroom (0dBFS = +18dBu) for line level
signals, allowing you to feed the ADC from
other sources such as alternative mic pres
etc. However this also provides a path in
which you can insert processing outboard
such as EQ & compression between the mic
pres and ADC - useful!!

Clocking with the ASP880
There are two ways to integrate ASP880
into your system digitally:
• As a MASTER clock source - internal clock
• As a SLAVE device - external clock
Master Clock Operation - INTERNAL
Assuming that you are connecting the
ASP880 digital output to a DAW/recording
interface with either AES or ADAT inputs,
the ASP880 can be set as MASTER clock

Slave Clock Operation - EXTERNAL
You may have a studio master clock source
such that all digital devices synchronise to
your session sample rate, or perhaps you
would like the ASP880 to follow your DAW/

not have to reconfigure the unit when you flip
between sessions at different sample rates.
In order to do this, you must set the ASP880
digital card to SLAVE to an external clock
