Installation Overview - Russound MCA-C3 User And Installation Manual

INSTALLATION OVERVIEW

Ventilation Requirements
Important: The MCA-C3 should be situated so that its location or position
does not interfere with its proper ventilation. Do not block vents above or to
the sides of the unit, as it requires ventilation for proper operation. Do not
expose to excessive dust, and do not allow dust to build up on the unit and
block vent holes. Do not place the MCA-C3 above or below a heat-generating
component such as an audio amplifier.
Be sure to leave at least 2 inches of space to the sides of the unit with open air
flow above. A single-space rack mount vent or about 1.75 inches must be kept
clear above and below the unit.
Installation
The MCA-C3 controller can be rack mounted or placed on a shelf in an
equipment rack. The controller occupies two rack spaces with feet removed.
The controller can be installed in an equipment rack using the included
rack-mount ears and hardware to attach the ears to the controller chassis.
Up to six controllers can be connected for up to 36 zones on the system.
Electrical Power
The MCA-C3 operates at 100-120VAC ~60 Hz or 220-240VAC ~50 Hz. Voltage
is selected by the voltage switch on the rear panel and incorporates the
appropriate detachable power cord. It is recommended that the MCA-C3 and
the source equipment be plugged into a dedicated 20-amp circuit. A power
line conditioner can reduce interference problems caused by noise found in
some electrical systems.
The power switch for the unit is on the front panel.
Do not connect the controller's main power feed until all other
connections have been made and verified. Live connection or
removal of the keypad wiring or other wiring when the system
is powered can cause communication problems in the network.
Double-check terminations during each phase of the installation
to prevent accidental damage. Incorrect wiring is the number one
cause for non-warranty product damage.

Power Management and EU Standby Power Requirements
The MCA-C3 controller meets EU Standby Power requirements by using
power management to turn off the controller and sources.
After the last zone is powered off and the Home Theater trigger input
is inactive, the sources are powered off after five minutes. Then if there is
no activity, the home theater trigger turns off in another minute. Finally,
the controller is placed into standby after another minute. Standby power
consumption is less than 1 watt.
Any keypad activity will wake the system from standby. In addition, Wake On
LAN may be used to wake the system from standby.
Important Considerations
• Disconnect the power cord before making any connections to the
controller.
• Verify that all connections and polarity are correct.
• Keep all power cords away from all signal cables to prevent humming from
induced noise.
• Choose reliable signal cables and patch cords.
• Label all wires with the room location at both ends of the wire.
• Avoid running speaker wires or signal cables close to house electrical
wiring for any distance. If you have to run them parallel, make sure to space
the wires at least two feet from the AC line. If you need to cross an AC line it
should be at a 90° angle.
• For multiple controllers, the controller ID must be set with the rotary switch
on the rear panel. Each controller must be set to a unique number before
powering connected controllers.
Important: The necessary software (SCS-C5) to program and configure the
system is available via download from the doc center at www.russound.com.
With your laptop, you can configure the system and name all of the zones prior
to connecting with the MCA-C3 controller. See Section on page 27 for items to
be programmed with the software.
