CONNECTION
Connect the AC cord to a properly grounded 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 balanced XLR plug contain-
ing the “Right” portion of the stereo signal to the Right Main Input. Connect a
balanced XLR plug containing the “Left” portion of the stereo signal to the Left
Input.
For a TRS stereo input configuration, connect a Tip-Ring-Sleeve stereo plug into
the front panel STEREO IN input. This cable may come from a mixer’s headphone
output for example.
The Aux Inputs are connected in the same manner as the discreet right/left input
configuration listed above.
To send a mono signal to the RA62b, connect an XLR jack to either Main Input, or
a single 1/4” Tip-Sleeve or RCA plug into either Aux Input input and press in the
front panel MONO/STEREO switch. This mono signal will be fed to both the right
and left sides of the headphone outputs.
INSERTS
The inserts have been provided so you can directly access each headphone
output with its own program material.
The inserts
require
Tip-Ring-Sleeve connectors, with right and left signals on the
tip and ring respectively. If you use a TS mono plug - you will only hear sound out
of one side.
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 that corresponding output.
CAUTION: Plugging a mono 1/4” TS plug into the Headphone
Outputs may cause permanent damage to the unit because
one side would be shorted to ground.
NEVER PLUG A MONO
PLUG INTO ANY OF THE HEADPHONE OUTPUTS.
