Installation
MA45CD Installation
Remove all packing materials. Check that all foam and plastic padding has been removed. If you want
to use the amplifier in a 19” Rack, you must first install the 19” flaps. Then screw the amplifier/CD player in
a 19“ Rack. Connect all cables.
Always disconnect from electric mains power supply before cleaning or servicing.
Damages caused by non-observance are not subject to warranty.
Set Up and Operation
Before plugging the unit in, always make sure that the power supply matches the product specification
voltage. Do not attempt to operate a 120V specification product on 240V power, or vice versa.
Do not supply power before all components of the system are set up and connected properly.
DC power or battery supply's connection
• The unit will also operate with an external 12V battery or another source with negative (-) as ground.
Power connection is made at the DC terminal strip on the real panel.
• If the AC power supply fails, transfer to DC power is instantaneous, automatic and silent.
• The battery power supply is operated by the primary switch.
• The amplifier is not capable of recharging the connected battery.Thus, it is recommended to have a
suitable device at hand. When the amplifier is on the DC power source, the nominal power handling
capacity operated drops by approximately 20%.
Input Connection
Microphones
The MA45CD is equipped with 3 inputs. They can be used with unbalanced low impedance devices
MIC-1, MIC-2
These two microphone inputs are unbalanced type and are provided with a double pole phone jack.
