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
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!
