EAP70D Broadcast Audio Processor

The EAP70D is an SDI embedded audio processor /automatic level controller, which allows audio to be reconfigured to match a station's infrastructure. This unit enables you to process up to 4 channels (1 group) of audio. Audio processing includes audio ALC, manual gain, phase inversion, mute, shuffling and mixing. All audio channels can be mixed multiple times, and re-embedded into different audio channels.

The EAP-70D broadcast audio processor has one composite analog video output and dual mono/stereo analog audio output for monitoring or other use. It generates up to 4 audio level meters for display in the composite analog video output or with RCP70D. This allows the signals to be controlled and monitored more effectively, seeing and hearing (with RCP70D) changes to the signal.

The EAP-70D audio processor has two modes for audio level control, ALC or manual gain control, which are selectable for different purpose. The ALC is exceedingly effective at controlling levels. It controls the average output level around -20dBFS and limits the peaks below -8 dBFS, the combination of averaging the level around -20dBFS and of holding peaks below -8 dBFS packages the audio perfectly for natural sound quality and for most transfer purpose.
