Usage

APB-112 OW-D is designed for use as a distribution audio amplifier for press conferences. It features one

digital input from Dante network and twelve analog audio outputs with individual output level switch – MIC/LINE.

There is no signal processing inside. All desired processing should be done in other devices (e.g. mixing console or

DSP). So, the APB-112 OW-D is suitable for fixed installations with integrated Dante network.

For proper operation and to maintain declared parameters, it is necessary to drive the APB with the correct

signal level from Dante network. The nominal analog output level of APB is +6dBu which corresponds to -20dBFS

(FS = Full Scale) of digital signal on Dante network. So, we recommend to drive the APB with digital signals

somewhere between -30dBFS and -18dBFS. Also, it is very useful to drive the APB with a processed signal e.g. with

applied compressor and limiter to reduce the dynamics of the signal especially for speech.
