Get to know this product.

Provides a single DM 8G® Fiber input for any DigitalMedia™ Switcher with modular input card slots. Includes stereo downmixing of multichannel input signals to enable simultaneous distribution of multichannel and 2-channel audio.

The DMC-S-DSP is an input card designed for use with any card-based Crestron® DigitalMedia™ Switcher. It provides one DM 8G® Fiber input, with complementary HDMI® pass-through and analog audio outputs. The DM 8G Fiber input enables the connection of a DM 8G Fiber transmitter, or the output of another DM® switcher, using a single strand of multimode fiber.

The DMC-S-DSP provides all the features of the DMC-S with the addition of downmixing to enable the simultaneous distribution of multichannel 7.1 surround sound and 2-channel stereo signals. It is recommended for use with surround sound sources to allow the original multichannel signal to be distributed to rooms with surround sound systems, while simultaneously distributing a 2-channel downmix signal to stereo-only rooms and devices.

DigitalMedia 8G™ Fiber

  • Engineered for ultra high-bandwidth and ultimate scalability, DigitalMedia 8G Fiber (DM 8G Fiber) provides a true one-wire lossless transport for moving high-definition video, audio, Ethernet, and control signals over multimode fiber. DM 8G Fiber handles uncompressed Full HD 1080p video signals with support for HDCP, Deep Color, 3D, and high-bitrate 7.1 audio, as well as computer signals up to WUXGA. All signals are transported over one strand of multimode fiber, supporting distances up to 1000 feet (300 m) using CresFiber® 8G, or 500 feet (150 m) using other multimode fiber optic cable.

HDMI® Pass-Through

  • Every DM switcher input card includes an HDMI output port, which can be used to pass the input signal through to a local audio processor or video monitor, or to feed a second DM switcher for output expansion purposes.

Audio Extracting and Downmixing

  • The DMC-S-DSP also includes an unbalanced analog audio output, allowing stereo audio signals to be extracted from the digital input and fed to a multiroom audio distribution system. Built-in DSP allows multichannel surround sound signals to be decoded and downmixed to stereo. The stereo downmix signal is automatically routed to the analog output, and can also be routed via any switcher output for distribution to stereo-only displays and other equipment. The analog output includes volume control that is adjustable via a control system using a keypad, touch screen, handheld remote, or mobile device.

Standalone DM 8G Fiber Receiver

  • In addition to its use as an input card for DM switchers, the DMC-S-DSP may also be used with the DMCI DigitalMedia Card Interface to provide a DM 8G Fiber receiver solution that's perfect for installation in an equipment rack or AV cart, or as a portable display interface.
  • To configure a DM switcher complete with input and output cards, cables, and other peripherals, please use the online DigitalMedia Switcher Configuration Tool.
