POWER: For connection to a Rolls PS12, or 12 VAC 300mA.

LINK: 1/4” TRS jack for connection to another RA53 LINK jack. Linking two units together provides 10 channels of monitoring from a master stereo signal, with four channels having an insert option.

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.

AUX INPUTS: RCA input jacks for connection to a signal source such as a CD or cassette player.

CHANNEL 2 INSERT: 1/4” TRS jack for receiving a stereo signal and directly accessing Channel Two output.

CHANNEL 1 INSERT: 1/4” TRS jack for receiving a stereo signal and directly accessing Channel One output.
