STEREO LINE INPUT
Digital Version Audio Connections (AMP A)
These include A and B source inputs (AES).
Pin 1 – A In SH
Pin 3 – A In HI
Pin 2 – A In LO
Pin 4 – B In SH
Pin 6 – B In HI
Pin 5 – B In LO
The four blue-handled slide switches (SW1, SW2, SW4, SW7) mounted
at the top of the card are normally set at the factory for the AES standard
(“up”). Note A & B inputs may be set separately: SW7 and SW4 are for
input A, SW1 and SW2 for input B.
Control Connections (AMP C, D)
These are identical for both analog and digital versions of the SLD-5
module. All control ports (except On Tally) are opto-isolated. Functions
include remote on and off, on tally, ready, and start/stop for remote source
machines. With the exception of Sequence and On Tally, each function is
available twice, for both A and B source ports, allowing it to follow the
module's A/B source selector switch.

To Turn the Module ON & OFF from a Remote Location
In the case of stereo line input modules, “remote location” can also
refer to a remote source machine that is feeding its audio to the module in
question. A 5 volt signal (which may be sourced by the external machine),
In passing, the three 4-
position dipswitches
(SW3, SW5 and SW6)
mounted in the middle of
the SRC-500 piggyback
card are for factory use
only. Do not disturb their
settings!
