DESCRIPTION

FRONT PANEL

Note: Descriptions for Channel One through Channel Five are identical.

OUTPUT: 1/4” and 1/8” (3.5mm) Tip-Ring-Sleeve jacks for connection to a standard pair of headphones or earphones. Output impedance is 10 Ohms. 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.

JOIN: 1/4” TRS jack for connection to another RA53b JOIN jack. 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.
