If racks are to be transported or used for mobile use, additionally fasten the devices by connecting the rear
brackets with the side or ground bars of the rack. In this way, the amplifier cannot be pushed backwards. The
front panel alone is not designed to absorb acceleration forces occuring during transportation.
INPUTS
A good cable run improves 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 humming and noise trouble. If long cable runs are unavoidable, you should use balanced cables.
Professionals recommend to connect the input-cables via balanced XLR-jacks.

Occupation balanced stereo-1/4“ jack-plug:
OUTPUTS
The high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long and thin
cables 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.
Connect your speaker-systems via the Speakon-plugs or the Banana/screw combination (occupation red +,
black -).
Switch-adjustments
Ground Lift-switch:
This switch allows the signal ground or chassis ground to be separated in case of a ground conflict. For
highest safety of the equipment, it is recommended to keep the Ground Lift-switch in the GND FLOATING-
position. In case of a ground conflict please set the ground lift-switch to GND LIFT.
CONNECTION TO THE MAINS
Connect the amplifier only after having made sure that the right voltage (230 V) is supplied and that the
ground lead is earthed. This device falls under potection class I. Do not detach the ground lead from the
housing!
