XLR Connector Pin Balanced Connection Unbalanced Connection
PIN 1 COMMON GROUND
PIN 2 + INPUT SIGNAL
PIN 3 - INPUT No Connect
T ABLE OF I NPUT AND O UTPUT C ONNECTIONS
Unbalanced connections should be made by connecting the unbalanced signal output to pin 2 of
the Instant Replay and ground to pin 1, with pin 3 left unconnected.
Analog Audio Outputs
The main A NALOG O UTPUTS are a pair of male XLR-3 connectors. The output is electronically
balanced, and is capable of driving loads of 600 ohms or greater. Full scale output level is +25
dBu with the O
UTPUT A TTENUATOR in the 0 position. Output cables should be wired the same as
shown above for the inputs.
Unbalanced connections are achieved by connecting pin 2 of the Instant Replay XLR Output to
the unbalanced input and pin 1 to ground, with pin 3 left unconnected.
Output Attenuator Switch
The O UTPUT A TTENUATOR switch is located on the rear panel. Set this switch to the in position
for operation of Instant Replay with equipment having a nominal operating level of +4 dBu. Set
the switch to the out position for use with equipment operating at -10 dBm.
The switch has no effect on the L EVEL M ETERS , digital audio outputs, or the H EADPHONE
O UTPUT .
Headphone Output
The H EADPHONE O UTPUT always carries the same signal as the Main outputs, but its level is
controlled by the H EADPHONES L EVEL control on the front panel.
When the P REVIEW button is activated in Stop mode, the H EADPHONE O UTPUT is active and the
Main Outputs (A NALOG O UTPUT , AES/EBU D IGITAL O UT and IEC-958 II O UT ) are turned off
during subsequent playback. It may be helpful to use the H EADPHONE O UTPUT for control room
monitoring, while the Main Outputs provide the main feed to a mixer or transmitter.
