The DCM-4 is a 2U rack mountable matrix mixing module for the D-Mitri digital audio plat form which c an combine u p to 28 8 channels of audio input to 288 buses, mixed to 288 outputs. The DCM-4 receives all audio inputs from and sends all outputs to up to four DCP core processors via Matrix Link, a dedicated, ultra-low latency Ethernet connection that carries 96 kHz/32-bit audio between D-Mitri’s processing and matrix modules. Mixing and routing are fully dynamic under the control of D-Mitri’s CueStation software. D-Mitri is a sophisticated digital audio platform which is the basis for a family of powerful modules aimed at providing comprehensive audio processing, matrix mixing and routing for a variety of professional audio applications, including theatrical and spectacle productions, theme parks, and active acoustics. D-Mitri systems feature an extremely flexible and highly programmable control scheme that can be customized by the user via the Python scripting language and Open Sound Control real-time protocol (both open-source tools) to accomplish even the most complex tasks. D-Mitri modules communicate using the Ethernet/AVB standard, which provides guaranteed QoS (quality of service) and very low-latency.S el e c tio n s of D- Mit ri m o d u l e s c a n b e assembled to provide nearly any configuration of digital or analog inputs and outputs and channels of processing. The DCM-4 facilitates dynamic mixing and routing for applications requiring large numbers of channels. The DCM-4 is unique: no other hardware matrix mixer of its size and quality exist. The DCM-4 has two additional redundant Ethernet ports for connecting to a separate control network, to receive communication from CueStation software or an external hardware controller. -Provides full dynamic matrix mixing of 288 inputs to 288 buses to 288 outputs. -Dynamic mixing and routing controlled by CueStation software. -Processes streams of up to 32 bits of resolution at 96 kHz sample rate. -Processes streams of up to 32 bits of resolution at 96 kHz sample rate. -Sends and receives audio to and from D-Mitri processing modules via Matrix Link. -Redundant control ports. -Additional redundant Matrix Link port.
