2 Installation
Normal these signals to the appropriate analog
inputs.
Likewise, the RMX
digital’s analog outputs may
be routed through a patch bay normalled to stan-
dard peripherals such as analog on-air processing
gear, recorders, telephone hybrids, etc.
Each analog input is designed for line level (+4
dBu). Session file settings allow any input to be
software level trimmed (by up to +/-15 dB) so that
unbalanced -10 dBv devices can be directly con-
nected to the console. Note that microphones must
be separately preamplified and processed before
being connected to the console.
Digital Connections
Three-pin digital inputs accept AES-3 (AES/
EBU) compatible signals with sample rates of 25
to 50 kHz. Each digital input goes through sample
rate conversion (the console’s internal sample rate
is 48 kHz). In most cases, digital inputs can also
accept unbalanced S/PDIF signals. Refer to Un-
balanced Connections on the next page for details.
Each digital output is an AES-3 compatible sig-
nal. AES-3 outputs cannot connect directly to an
S/PDIF input. To do this requires a signal trans-
lation interface.
A receptacle contact is inserted into the hous-
ing with its locking tab side toward the locking
tab slots on the side of the connector housing. A
slight click can be heard when the contact’s lock-
ing tab springs up into the locking tab slot.
To remove a contact from a housing, the 70-
129 Contact Removal Tool (included in the 76-
1401 tool kit) is required. Insert the tool’s tip into
the locking tab slot and press the locking tab down
while lightly pulling on the wire to remove the
contact from the housing.
AUDIO CONNECTIONS
Analog and digital audio connections take ad-
vantage of the three-pins per row design of the
AMP MOD IV housings. Three-pin housings are
used for digital connections and six-pin housings
are used for analog connections.
Audio wiring has this orientation:
• The audio shields connect on pins 1 and 4
• The audio low wires, typically black,
connect to the middle pins (pins 2 and 5)
• The audio high wires, typically red,
connect to pins 3 and 6
When inputs come from mono sources like mic
processors or hybrids, two separate signals can
connect to each six-pin connector to maximize
input connector usage.
Analog Connections
There are no analog interstage patch points in
the RMX
digital console. To use the console with a
patch bay, connect line level analog outputs from
the peripheral devices directly to the patch bay.
