Installation
The following steps are written in the recommended installation order.
Mount the CXD Amplifier
The CXD Series amplifiers are designed to be mounted in a standard rack-mount unit.
The amplifiers are 2RU high, the CXD4.3 and CXD4.5 are 381 mm (15 in) deep, the
CXD4.2 is 229 mm (9 in) deep.
Depending on the depth of your rack, the Rear Rack Ear Support kit (FG-000031-00)
may be required for rack mounting. Refer to http://qsc.com/products/ under
Accessories for details.
CAUTION!:
Be sure that nothing is blocking the front or rear
ventilation openings, and that each side has a minimum of
2 cm clearance.
1. Use the proper fastening hardware (not included) to secure the amplifier in the rack. The CXD4.3 and CXD4.5 have four front and four rear
mounting tabs. The CXD4.2 has four front mounting tabs.
AC Mains
WARNING!:
When the AC Power is on, there is a potential of having
dangerous voltage at the output terminals on the rear of the amplifier. Use
caution not to touch these contacts. Turn off the AC Mains disconnect switch
prior to making any connections.
The CXD amplifiers have a Universal power supply 100 – 240 VAC, 50 – 60 Hz, with an IEC
locking connector.
1. Connect the IEC AC cable between the amplifier rear AC connector and the AC source.
AC Power
NOTE:
If the amplifier has no audio for fifteen minutes, the amplifier stops switching. The amplifier returns to the Run mode the instant audio is
present.”
When you remove power from the amplifier, then re-apply the power, the amplifier returns to its last state.
