RDL EZ-ADA4 Stereo Audio Distribution Amplifier

[Music] in electronics a distribution amplifier or simply distribution lamp or da is a device that accepts a single input signal and provides the same signal to multiple isolated outputs these devices allow a signal to be distributed to multiple destinations without ground loops or signal degradation they are used for a number of common engineering tasks including multiple amplification cable television splitting monitor and front-of-house mixes and tapping a signal prior to sending it through effects units to preserve a dry signal for later experimentation an audio distribution amplifier also known as a press feed a pool feed a media feed press box or an ad a takes a single audio feed usually a line input but it may be a microphone input and outputs multiple line or microphone outputs this can be done using a passive feed where the signal is split among the outputs or as an active feed
