RIGHT/STEREO INPUT: 1/4" TRS jack for connecting the "Right" side of a stereo signal. If used alone, a 1/4" TRS plug with the "Right" side of the program material on the tip, and the "Left" side on the ring may be connected for stereo operation. For example, a stereo headphone output from a mixing console may be directly connected to the Right/Stereo jack via a stereo TRS cable. LEFT/MONO INPUT: 1/4" TS jack for connecting to the "Left" side of a stereo signal. If used alone, a 1/4" TS plug with a mono signal will feed both sides of the RA53 Outputs.

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. MODEL RA53 POWER 12VDC LINK RIGHT/ STEREO INPUT LEFT/ MONO INPUT RIGHT AUX INPUTS 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 connected 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.
