THE PATCHBAY
The ASP8024PB optional
patchbay system provides
front panel access to the
connections provided on
the rear of the standard
console as well as a number
of additional ‘patch points’.
Patching is implemented
using TT size jacks with D-
sub connectors provided for
the studio systems
interfaces.
All default signal paths are
fully normalled to avoid
unnecessary patching and
functional patch point
blocks are arranged in a
horizontal format for ease of
identification.
Interfacing for two 24track
machines is provided and all
patchbays are supplied
with 144 tie-lines as
standard.
1. TAPE RETURN PATH
Provision is made for
interfacing to two 24-
track machines. Tape
machine A playback is
normalled from the
relevant D-sub interface
to the Tape inputs of
channels 1-24. Tape
machine B playback is
normalled to channels
25 onwards up to 48 if
this many channels are
fitted.
3. MULTITRACK SENDS
The sends to both 24
track machines are
normalled from the 24
bus outputs. The
machine sends may of
course be overpatched
from channel insert
sends, sub-groups etc.
4. STEREO INPUTS
The stereo device
outputs such as reverbs
etc are interfaced via 1/
4 inch jack sockets on
the rear of the console.
These are normalled to
the 4 stereo inputs
through the patch jacks
shown above.
2. CHANNEL PATH
A rear panel jack socket
is provided for
interfacing external
devices such as
synthesizers. This signal
is available as the Device
Output on the patchbay
and is normalled to the
channel line input.

5. SUB GROUPS
The eight Sub Group
outputs are normalled to
a D-sub connector and
may be used for
providing outputs to a
device such as a non-
linear editing system for
example.
6. STEREO TAPES
The stereo tape
machines are interfaced
on XLR connectors fitted
to the rear of the
console. The feeds to
and from the XLRs are
normalled via the patch
bay from the Mix output
and to the 2 track
monitor returns
respectively.
