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).
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!
Welcome & Thank You
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!
•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 global operation

Safety Information
Important Safety Instructions
Please read all of these instructions and save them for later reference before connecting the mains IEC power cable and powering up ASP880. To prevent electrical shock and fire hazard follow all instructions on the rear of the ASP880.
ASP880 does not contain any user serviceable parts inside the internal power supply and in the event of a power supply failure, please contact audient support so that we can arrange suitable service.
www.audient.com/support
A 1RU ventilation space above the unit is recommended and it is not advised to run the unit in a rack above hot units such as valve outboard and multichannel AD/DA converters without suitable ventilation space around the unit.
The internal switch-mode power supply design will accept any A.C line voltage from 90v to 264v @ 47-63Hz. Therefore the unit will work happily anywhere in the world but please ensure your A.C mains line voltage is within this specification and you use an
appropriate cable for the region. Consult a qualified technician if you suspect difficulties.
Do not attempt to tamper with the power supply or mains voltages - HAZARDOUS TO HEALTH.
! WARNING !
TO REDUCE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS TO
RAIN OR MOISTURE.
NO USER SERVICEABLE PARTS INSIDE.
PLEASE REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
