CONNECTION
Connect the Rolls PS12 Power Supply to the POWER jack on the RA53 rear
panel. Connect the power supply to an ac outlet.
Determine which input configuration you will use; either discreet right/left, TRS
stereo, or mono.
For a discreet right/left input configuration, connect a 1/4” TS plug containing the
“Right” portion of the stereo signal to the Right/Stereo Input. Connect a 1/4” TS
plug containing the “Left” portion of the stereo signal to the Left/Mono Input.
For a TRS stereo input configuration, connect a Tip-Ring-Sleeve stereo plug into
the Right/Stereo input. This cable may come from a mixer’s headphone output for
example.
To send a mono signal to the RA53, connect a 1/4” Tip-Sleeve plug into the Left/
Mono Input. This mono signal will be fed to both the right and left sides of the
headphone outputs.
The RCA Aux Inputs are connected in the same manner as the discreet right/left
input configuration listed above.
To LINK another RA53, simply connect a 1/4” TRS stereo cable to both LINK
jacks on two RA53 units.
INSERTS
The Channel 1 and Channel 2 inserts have been provided so you can directly
access Channel 1 and Channel 2 headphone outputs with their own program
material.
The inserts require Tip-Ring-Sleeve connectors, with right and left signals on the
tip and ring respectively.
When these insert jacks are used, the main Right/Stereo and Left/Mono, as well
as the Aux Inputs - are disconnected. Only the stereo signals sent to the Insert
jacks go to the corresponding outputs.
OPERATION
Shown below is a possible operation example for the RA53. Headphones are
connected to the Outputs on the front panel, and the other equipment is con-
nected to the rear panel as shown. The Left and Right Inputs to the RA53 are
connected to the mixer’s sub outputs, but could be connected to auxiliary sends
or even main outputs. The RCA Auxiliary Inputs are connected to a playback deck.
For individual monitoring, a stereo TRS connector could be plugged into a stereo
auxiliary send from the mixer to an Insert jack on the RA53. This way, different
material may be monitored on Channels 1 and/or 2 than that of the main inputs.
