Description Of The Device; Features; Connections - Omnitronic PAM-150 User Manual

The reason why some people have got accustomed to a certain noise level and are no longer disturbed is
that they have already suffered a hearing damage. This damage make the unsensitive to those frequencies
forming the loudest part of the noise. Getting accustomed to noise does not mean anything oter than trying
to get along with the hearing loss in everyday life. The hearing loss itself cannot be healed, it can only be
compensated by hearing aids.
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!

4.2 Connections

Install the device on a solid, plane, anti-slip, vibration-free, oscilation-free and fire-resistant surface.
Make sure that the power switch is set to OFF. Before you connect the devices, all units have to be switched
off.
The inputs of this PA-system are to be directly connected with the outputs of your audio source. Solo
entertainers can also directly connect their keyboard with the stereo channels' RCA-sockets. Further
microphones have to be connected with the Mic-sockets. Never connect any input with an amplifier output!
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.
In order to obtain highest sound quality, only use high-quality cables for connecting the devices. Make sure
that the cables are properly fixed.
At the mono input channels, the microphone signals are connected via the XLR-sockets, the line-signals via
the jack sockets.
