Page 4: Introduction
All aspects of the system setup are accomplished via a convenient web interface similar to what would be seen on a soho router. Just connect the MRC-816 to the home network, and navigate with a web browser to http://nexus816 The MRC-816 supports eight independently operated zones and infrared (IR) control of six external line level audio source components. -

(Tuner, CD, DVD, SAT, Music Server, etc) should also be installed at this location. The MRC-816 and source components can be placed on shelves in a wall unit in a media room, or rack mounted in a standard 19” rack mount system.

Page 12: Zone Connections
Using a properly configured 2.1mm coaxial plug, (see section: Wiring/Mute) connect the 2.1mm coaxial plug to the Mute jack on the MRC-816 rear panel. Terminate the other end as appropriate and connect to the 12VDC control output terminal on the device used to trigger audio mute. Be sure to maintain proper polarity from the trigger device control out to the 2.1mm coaxial plug. -

Page 15: System Power Up
SYSTEM POWER UP After the system wiring is complete, it is time to power up the system. The power switch for the MRC-816 is on the rear panel of the unit above the power cord. This system is designed to remain powered up continuously. Turn the power switch on the rear panel to the on position. -
Page 16: Firmware Updates
The USB flash drive to be used for the upgrade can have other files on it, but if there are a lot of files, the MRC- 816 may take a long time to initialize before the upgrade begins. If the MRC-816 does not initialize or download the update, delete the extraneous files, or use another flash drive with less files on it. - Page 17 The RS-232 Port on the MRC-816 is a DB9 female jack. Tx (transmit) = PIN 2, Rx (receive) = PIN 3, Ground = PIN 5. Communication settings are 19200 baud, 8 bits, 1 stop bit, no parity. Figure 45. RS-232 Port Pin Out...
