Rack Installation

The EP Series is built for 19” racks (483mm). 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.

Be careful when mounting the amplifier into the rack. Put the heaviest products into the lower part of the rack. Be aware that fastening the amplifier with four screws on the front panel is not enough.

If the racks are being transported or used for mobile use, additionally fasten the products 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 is not designed to absorb acceleration forces occuring during transportation.


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 humming and noise problems. If the cable runs are unavoidable, you should use balanced cables.


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 thr Bannana/Screw combination (red+, black-)

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.

Connect the amplifier only after having made sure that the right voltage (240V) is supplied and that the ground lead is earthed. This product falls under Class 1. Do not detach the ground lead.



After having connected your amplifier to the mains, turn both gain controls counter clockwise to the

“min” position. The last product to be switched on is amplifier. The “ON” and “ PROTECT” LED light up now. If it does not, check if the amplifier is connected to the mains correctly.

After the turn on delay the speakers are activated (PROTECT-LED is off).

After having set the volume controls of the pre-amplifier in nil position, turn the gain controls of your amplifier to mid-position. Now adjust the volume with the gain controls CH A and CH B

All important operating modes of the amplifier are arranged on the front panel.

-20 dB to 30dB



Output level

Short circuit or ompedance too low or signal distorted

Active during stabilisation period after switching on or when one of the protective circuits are activated

If you want to switch off the system, switch off the amplifier first in order to avoid acoustic shocks on the speakers.

We recommend a frequent cleaning of the product. Please use a soft lint free and moistened cloth.

Never use alcohol or solvents.

There are no serviceable parts inside the product except for the fuse. Maintenance and service operations are only to be carried out by authorised dealers.

Only replace the fuse by a fuse of the same type and rating.

Before replacing the fuse, unplug the mains lead.


Step 1: Open fuse holder on the rear panel with a screwdriver.

Step 2: Remove the old fuse from the fuse holder.

Step 3: Install the new fuse in the fuse holder.

Step 4: Replace the fuse holder in the housing.

Should you need any spare parts, please use genuine parts.

Should you have any further questions, please contact your dealer.
