8. Installation
Please note: When using an amplified system in public or industrial areas, a series of safety instructions has to be
followed that this manual can only give a part. The operator must inform on the current safety
instructions and consider.
a. Rack Installation
• This amplifier is built for 19" racks. The rack should be fitted with a cooling fan. When mounting the amplifier,
make sure there is enough free space around the device for the evacuation of hot air. Continuous overheating
will damage your device.
• Fix the amplifier with four screws M6.
• Be careful when mounting the amplifier. Put the heaviest device in the lower part of the rack. Note that
fastening the amplifier with four screws on the front panel is not enough. Use additional metal bars to support
the sides and the ground panel of the device.
• Attach the rear bracket to the ground or side bars when the device is to be transported. This keeps the
amplifier from being pushed backwards.
b. 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 may lead to
humming and noise trouble. If long cable runs are unavoidable, you should use balanced cables.
• Professionals are recommended to connect the input cables via balanced XLR jacks.
c. Bridged Mono, Parallel Mono and Stereo Wiring
1. BRIDGED MONO
• Turn off your amplifier.
• Set mode switch to BRIDGED MONO.
• Connect speaker + to the red terminal of channel A.
• Connect speaker - to the red terminal of channel B.
2. PARALLEL MONO
• Turn off your amplifier.
• Set mode switch to PARALLEL MONO.
• Connect speaker + to the red terminal of channel A and channel B.
• Connect speaker - to the black terminal of channel A and channel B.
3. STEREO
• Turn off your amplifier.
• Set mode switch to STEREO mode
• Connect speaker + to the red terminal of channel A.
• Connect speaker - to the red terminal of channel B.
d. Outputs
• The high damping factor of your amplifier ensures 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 be around 50. The longer a cable, the thicker it should be.
• Connect your speaker systems via the speaker plugs or the banana / screw combination (red+, black-).
