Installation
Rack Installation
The MA Series are fully 19” rack mountable. The rack you use should be a Double Door Rack where you
can open the front and rear panel. When mounting the amplifier into the rack, please make sure that
there is enough space around the amplifier for clear air flow.
Be careful when mounting the amplifier into the rack. Put the heaviest products into the lower part of
the rack. The front panel is not designed to absorb acceleration forces occurring during transportation.
Inputs
Short cables runs improve the sound quality remarkably. Input cables should be short and direct, since
high frequencies will mostly be absorbed if the cables are unnecessarily long. Besides that a longer
cable may lead to hum or noise problems. If the cable runs are unavoidable, you should use balanced
cables.
Outputs
The high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long and
thin cables used for low impedance (4-16Ω) speakers will influence the damping factor and thus the low
frequencies in a negative way. In order to safeguard good sound quality, the damping factor should lie
around 50. The longer a cable has to be the thicker it should be. For longer cable runs please ensure
the 100V outputs are used for 100V speakers.
Connect your speaker systems via the speaker terminals (COM = -VE)
Examples:
1) COM + 4-16Ω
2) COM + 70V
3) COM + 100V
Note: Please do not use more than one pair of output terminals on any one output zone.
Connections To The Mains
Before connecting the amplifier to the local mains voltage outlet should be checked to ensure the
available supply is 240V~AC 50Hz. This product is CLASS1 and requires a protective mains earth to be
connected at all times. DO NOT remove or disconnect the earth.
