    Item #: DM-DA4-4K-C

    The DM-DA4-4K-C is a DigitalMedia™ accessory that converts and splits a single 4K60 HDMI® signal to feed four separate DM 8G+® or HDBaseT® receivers. A single HDMI output is included to pass the input through to a local display, audio processor, switcher, or another DM-DA4-4K-C. Video and audio are passed from the input to all five outputs simultaneously without any change or degradation.

    PoDM+ and HDBaseT PoE+ power sourcing is enabled at all four DM® ports by adding a PoDM power supply (model PW-4830DUS or DM-PSU-3X8-RPS, sold separately). This enables certain DM receivers and HDBaseT devices to receive power through the CATx cable, eliminating the need for a separate power supply at each endpoint location.[1]

    A Gigabit Ethernet port is included to provide a single-point LAN connection for all connected devices, including DM receivers and HDBaseT devices. Gigabit connectivity at the DM-DA4-4K-C ensures a full 100 megabit connection for each connected device.[2]

    HDCP is globally selectable on the DM-DA4-4K-C to support version 2.2, 1.4, or none. EDID functionality is configurable to either pass EDID to the input from the device connected to the first DM output port, or to use a pre-fined default EDID optimized for 1080p60. CEC signals are not passed through the DM-DA4-4K-C, although most DM receivers can support CEC through integration with a control system via Ethernet.[3]

    One or two DM-DA4-4K-C units can be rack-mounted in a single rack space using the ST-RMK rack mount kit. Installation beneath a table or counter is enabled using the UTK-1U-HALF under-table mounting kit. Both mounting kits are sold separately.

    1. Enabling PoDM and PoE power sourcing requires an external power supply, model PW-4830DUS or DM-PSU-3X8-RPS, sold separately. Due to the inherent power loss that occurs over CATx cable, a maximum of 25.5 Watts is delivered at each PoDM+ or HDBaseT PoE+ powered device. Any wiring that is connected to a PoDM or PoE PSE port is for intra-building use only and should not be connected to a line that runs outside of the building in which the PSE is located.
    2. With regard to Ethernet, the DM-DA4-4K-C effectively functions as a basic 5-port network switch to provide LAN connectivity for the connected DM and HDBaseT devices. This allows those devices to be addressed, controlled, and monitored by a Crestron control system. The DM-DA4-4K-C itself is not addressable and has no controllable functions. Please note, a model DM-RMC-4K-100-C-1G receiver cannot be controlled through its connection to the DM-DA4-4K-C, and thus will only function as a simple AV signal receiver. All other Crestron DM 8G+ receivers are fully controllable via Ethernet through the DM-DA4-4K-C. For HDBaseT devices, please consult the specifications for each device to determine its compatibility with Ethernet over HDBaseT.
    3. CEC (Consumer Electronics Control) is a communications protocol used by many AV devices to enable remote control through an HDMI connection. CEC signals are not passed between the inputs and outputs on the DM-DA4-4K-C. However, Crestron DM 8G+ receivers can support CEC via an Ethernet connection to a control system through the DM-DA4-4K-C, which allows the control system to control devices through each receiver’s HDMI output. Please note, model DM-RMC-4K-100-C-1G receivers do not support this capability when connected to the DM-DA4-4K-C. HDMI and HDBaseT devices cannot be controlled using CEC through the HDMI or DM ports on the DM-DA4-4K-C.
    4. ST-RMK rack mount kit and UTK-1U-HALF under-table mounting kit each sold separately.
    5. The maximum cable length for DigitalMedia 8G+® (DM 8G+) or HDBaseT is dependent upon the type of cable and resolution of the video signal. Refer to the “Maximum DM 8G+ & HDBaseT Cable Lengths” table for a detailed overview. Crestron legacy cable models DM-CBL DigitalMedia Cable and DM-CBL-D DigitalMedia D Cable support the same resolutions and cable lengths as CAT5e. Shielded cable and connectors are recommended to safeguard against unpredictable environmental electrical noise which may impact performance at resolutions above 1080p. Refer to the Crestron DigitalMedia Design Guide, Doc. #4546 for complete system design guidelines. DM 8G+ is compatible with HDBaseT Alliance specifications for connecting to HDBaseT compliant equipment. All wire and cables are sold separately.
    6. HDMI connections require an appropriate adapter or interface cable to accommodate a DVI or Dual-Mode DisplayPort signal. CBL-HD-DVI interface cables are available separately.
    7. The HDCP version selection affects all inputs and outputs globally.
    8. EDID is handled between the DM OUTPUT 1 and HDMI INPUT connections only. Alternately, a pre-defined default can be selected.
