Audient ASP880 - Manual (Page 2)

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!
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
