APC875
introduce:Realize a variety of digital movie audio formats with a new decoding method. Based on the DSP algorithm, it realizes all-digital audio processing, and it is very easy to set up the fixed theater speaker system, which is suitable for various movie theaters. The large LCD screen displays function status, setting parameters, level gain, fault warning, etc.

application:Applicable to Galaxy Series and Extreme Series
Features

The main functions of APC875 are: AES/EBU digital audio signal receiving and conversion; DSP digital audio processing; 8 -channel signal input , 14 -channel output, frequency division, equalization, pressure limit, delay, etc.; built-in monitoring, can be left, center, right, Switching between left ring and right ring channels; built-in pink noise signal graphic envelope comparison debugging; complete interface functions; 2K , 4K digital audio, 1.3K analog audio, stereo, optical fiber, coaxial, microphone, USB , etc., can support TMS theater management system.
