Distribution Amp (DA)
Purpose
A Distribution Amp provides a means of routing a signal to many destinations, each with its own level control, overload indicator and mute switch. If you want to route a signal from one device’s output to multiple inputs you can simply connect many wires to the output node. Only when you need individual level control to each connected device is a Distribution Amp called for.
Controls
Input Level
Controls the signal level into the Distribution Amplifier. Changing this control will affect the Input Meter.
Note: It is possible to create an overload condition within the distribution amplifier if this control is set above +0dB. Such an overload may be indicated at the Input Meter.
Input Meter
Shows the RMS signal level entering the distribution amplifier.
Output Level
Allows control of the output level for each distribution channel.
Note: It is possible to create an overload condition at the output of the distribution amplifier if this control is set above +0dB. Such an overload will be indicated by the Output Overload indicator.
Output Overload
Lights whenever the distribution channel output attempts to exceed +35dB. This condition is only possible if the Output Level for the channel is set greater than +0dB.
Note: An overload which occurs within the distribution amplifier due to a greater than +0dB setting of the Input Level control will not be detected by the Output Overload indicators.
