Bosch 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. The DCNM-APS2 has no user controls and can be fully controlled remotely.
Controls and indicators
- Mains switch on the rear to power on the Audio processor and powering switch
- Ground-lift switch
