Analogue Line Outputs
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
standardwith100Ωoutputimpedanceand
+27.5dBu maximum level.
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!!
To activate the direct AD access press the
front panel A-D switch on each channel.
Digital Outputs - AES - S/PDIF
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
likely be using the AES professional output
so this switch can remain in the out position
until required.
Digital Outputs - ADAT SMUX
The digital card also provides simultaneous
ADAT optical output on the rear of the unit
with full SMUX double speed capability.
For <48kHz operation, a single optical
cable should be connected from the top
(1-4) ADAT port. This will provide 8-channels
@ 48kHz. For >48kHz operation, two optical
cables should be used, with four channels
carried on each for full 8ch 98kHz operation.
ASP880 & iD22 - Perfect Harmony
Combining ASP880 with our iD22 USB
recording interface via ADAT - you get 10
audient mic preamps, 10 top-of-the-range
Burr-Brown AD converters and 6 pristine
DAC outputs for monitoring! Nice!
