Outputs
The XLR 3 pin plug connectors are electronically balanced and can be wired unbalanced to
accept an output from domestic equipment. They have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase

Inputs

The XLR 3 pin sockets are electronically balanced, and can be wired unbalanced to accept an
output from domestic equipment. They have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase

Gain Control

Each channel has an input gain (GAIN) and a threshold level control (LIMIT LEVEL). Setting
the limit level to maximum (fully anti-clockwise) enables the input through to output to be
normalised using the input gain potentiometers. Once the unit is acting as a buffer with
gain/attenuation, the limit level can be set, with the recovery adjusted for the application.
Limiting is indicated by the power LED on the front panel. (see page 50).

Mode Switch

This switch changes the unit from dual mono to stereo mode. In stereo mode, only the
pre-sets for channel 1 (left) are active and they are applied to both channels. Stereo limiting
operates by limiting both left and right outputs if either left or right input needs to be
limited. Dual mono limiting operates by limiting left and right signals individually – you can
use the RB-SL2 as two separate mono limiters.
