Bogen Communications BRG1R

Bridging Input Module (BRG1R): The BRG1R input module has a mono-balanced input and a buffered pseudobalanced output that enables the connection of several amplifiers to each other in a daisy chain configuration without creating ground loops between units. It has an RCA jack for both the input and the output connections. The module has a gain/trim control that allows the gain to be adjusted plus or minus 5 dB relative to 0 dB nominal gain. It has the ability to mute lower priority modules and be muted by higher priority modules. The module is able to assume any of 4 priority levels.

It has a continuously variable ducking control that will enable attenuation of the input signal from a minimum of 10 dB to a maximum of 48 dB relative to the normal unmuted condition and a gradual fade back from mute when the mute control is deactivated. The buffered output is not muted. The module has a VOX/gating circuit to control muting of lower priority modules and an internal gating circuit with separate controls for gate threshold and duration. The module’s output is assignable to either or both of two mixing buses.
