6.3.1. 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
6.3.2. 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
6.3.3. Gain
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 flashing.
6.3.4. Mode
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.
