OUTPUT: 1/4" and 1/8" (3. 5mm) Tip-Ring-Sleeve jacks for connection to a standard pair of headphones or earphones. LEVEL: Controls the amount of output signal from the indicated channel. POWER LED: Indicates that the RA53b is connected to the power supply and is on. REAR PANEL POWER: For connection to a Rolls 12 Volt (maximum) power supply. RIGHT/MONO INPUT: 1/4" TS jack for connecting the "Right" side of a stereo signal. If used alone (nothing connected to the LEFT/STEREO jack), a 1/4" TS plug with a mono signal will feed both sides of the RA53b Outputs. LEFT/STEREO INPUT: 1/4" TRS jack for connecting to the "Left" side of a stereo signal. If used alone, (nothing connected to the RIGHT/MONO jack) 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 Left/Stereo jack via a stereo TRS cable. L /R INPUTS: RCA input jacks for connection to a signal source such as a CD or cassette player. BALANCED INPUTS: XLR input jacks for connection to a balanced line level source such as the output of a mixer. Linking two units together provides 10 channels of monitoring from a master stereo signal, with six channels having an insert option. CHANNEL INSERTs: 1/4" TRS jacks for receiving a stereo signal and directly accessing the indicated channel's circuitry. 5 2 CONNECTION Connect the Rolls Power Supply to the POWER jack on the RA53b rear panel. 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/Mono Input. Connect a 1/4" TS plug containing the "Left" portion of the stereo signal to the Left/Stereo Input. [. . . ] To link another RA53b, simply connect a 1/4" TRS stereo cable to both JOIN jacks on two RA53b units. INSERTS The Channel 1, 2 and 3 inserts have been provided so you can directly access Channel 1, Channel 2 and Channel 3 headphone and earphone outputs with their own program material. The inserts require Tip-Ring-Sleeve connectors, with right and left signals on the tip and ring respectively. [. . . ]
