Subjectively, the hearing loss feels like dampened ears. This effect weakens with the time, but a loss in
hearing sensitivity often remains.
In order to relax the hearing sufficiently, the noise level should not exceed 70 dB(A) for 10 hours. Higher
noise levels during this relaxing period can prevent the relaxation and promote a permanent hearing damage
(Tinitus) or hearing loss.
Therefore: Whoever wants to maintain his hearing should use hearing protectors!

INSTALLATION

Please note: when using a PA-system in public or industrial areas, a series of safety instructions have to be
followed that this manual can only give in part. The operator must therefore inform himself on the current
safety instructions and consider them.

Rack installation

This amplifier is built for 19" racks (483 mm). The rack you use should be a Double-Door-Rack where you
can open the frontpanel and the rear panel. The rack should be provided with a cooling fan. When mounting
the amplifier into the rack, please make sure that there is enough space around the device so that the
heated air can be passed on. Steady overheating will damage your device.
You can fix the amplifier with four screws M6 in the rack.
Be careful when mounting the amplifier into the rack. Put the heaviest devices into the lower part of the rack.
Be aware that fastening the amplifier with four screws on the front panel is not enough. In order to ensure
safety, additional fastening by using ground and side bars is necessary.
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.
