The MAP-3901 is the latest generation metadata and audio processor in the Densité family, offering sophisticated audio signal processing on a single 3 RU module. The powerful and versatile processing platform delivers significant value by simultaneously processing up to 56 channels of audio (16 channels of embedded audio from the video, plus others generated internally). Functions include dual downmixing, level control, channel shuffling/mixing and an on-board DSP engine that can run simultaneously with up to two optional Dolby-E decoders, four optional Dolby Digital & Digital Plus encoders, and two optional upmixers (2.0 to 5.1).
