HDMI Output
The MH2-4K HDMI output delivers 4K@60 video via an HDMI cable to HDMI
display screens, AVRs or sound bars. CEC commands can be used to control the
sync device.
Video File Information
The MH2-4K supports MPEG-4 encoded videos with maximum video resolution
up to 4K@60. Test all les before deployment. See BrightSign specications for
details: www.brightsign.biz/application/les/7715/5111/4033/HS4-02252019.pdf
Audio Output
The MH2-4K can output digital and/or analog audio simultaneously, as directed by
BrightAuthor settings. The digital Toslink jack outputs optical audio signals, and the
3.5mm jack provides stereo analog audio. The audio signals on the HDMI output
may be turned off and on via software.
Push-Buttons
To control media using push-buttons, connect
EasyPlug push-buttons to each position. Compatible
push-buttons are available in several colors; blue LED
ring is shown, Model 013-100.
The EasyPlug push-button has an RJ9 connector for easy
installation and long term reliability.
Micro SD Card Slot
The programming instructions for custom functionality are stored on a Micro SD
card with the video and audio les. Media les placed on the root of the Micro SD
card autoplay on power up. If the Micro SD card is updated to add new video les,
check to make sure any custom programming remains on the card.

Serial Communications
Control Port (RS-232)
The MH2-4K can send and receive serial commands via RS-232 at any Baud rate
selected via BrightAuthor. The port is a modular RJ-45 jack; adapter cables are
available for 3.5mm or DB-9 serial ports. The port may be set for Null or Straight
using the switch located beside the RS-232 port.
Control Bus (RS-485)
The RS-485 control bus allows the MH2-4K to interact with devices such as the
Audio Authority TouchSelect panels or the 1895 Visual Volume knob. The MH2-4K
can also control switch modules or ampliers that are linked by the Control Bus.
The MH2-4K is unit ID 0, all on-board push-button positions respond to commands
addressed to ID 0. All commands are echoed on the RS-232 control port and
RS-485 control bus, regardless of ID.

Example System: Sound Bars
The MH2-4K does more than play media in this engaging sound bar demo - it coordinates a complex
audio demo with video and lighting effects. Customers can audition sound bars, select media, add
rear speakers, compare TV speakers to sound bars, and adjust volume. Push a button on the right to
hear a sound bar, which also triggers the rst media le to play, and the shelf to light up. Lights under
the shelf also highlight the selected subwoofer. The user selects media using a small touch screen.
The rear speakers are powered via a smart amplier that tracks volume control with the selected
sound bar. After a period of inactivity, the display returns to a silent state, ready for the next customer.
