Bosch DICENTIS DCNM-APS2 Audio processor and powering switch

The Audio processor and powering switch is responsible for routing, controlling and processing the audio. The DCNM-APS2 also supplies power to the discussion and multimedia devices.

The device includes an intelligent adaptive acoustic feedback suppressor, echo cancellation and two 5‑band parametric equalizers for optimal speech intelligibility. It has two audio inputs for inserting external analogue audio signals into the system and mix‑minus is provided for connecting the DICENTIS Conference System to video conferencing equipment. The DCNM-APS2 also has two audio outputs used for mix‑minus and to connect an external sound reinforcement system.

The built‑in Ethernet switch connects all devices in the system together in a network and supports loop‑through connection. This makes it possible to connect a DICENTIS discussion device to another DICENTIS discussion device. Even the last DICENTIS discussion device in the loop can be connected to a DCNM-APS2 to create cable redundancy
