Adapting The Monitors To The Room Acoustics; Operation; Cleaning And Maintenance - Omnitronic PMM-4 Bedienungsanleitung

These monitors are magnetically shielded so that you can install them next to monitors, e.g. computers or
video processing devices. Nevertheless keep a minimum distance of 8 cm to the monitor. If the image of a
sensitive device is distorted nevertheless, increase the distance.
Please take your time to experiment with your new monitors without the pressure of a recording session so
that you get a feeling for these loudspeakers. If possible, use well-known sound material in order to feel the
neutrality of these monitors. Experiment with different locations and positions before using the possibilities of

adapting the monitors to the room acoustics.

6.2 Adapting the monitors to the room acoustics
Use the DIP-switch on the rear panel for adapting the monitors to the room acoustics.
Please do first try to compensate any sound coloration by changing the installation locations and positions.
Mid Boost can be used for adjusting the mid-range in order to adjust the precence area.

7. OPERATION

Switch the device on. After switching on the speaker-system, wait 8 to 10 seconds until you turn the volume-
control in order to avoid speaker-damage.
Caution! Increase the level only so far that the CLIP-LED lights up shortly. Thus, you avoid that the output
signal is distorted and your speakers are damaged.
When operating the speaker-system, please make sure that the loudspeakers always sound well. When
distorsions can be heard, either the amplifier or the loudspeaker is overloaded. Overloads can quickly lead to
amplifier or speaker damage.
In order to avoid damage, please reduce the volume immediately when distortions can be heard. When
speaker-systems are destroyed by overload, the guarantee becomes void.
Always check the sound pressure level with a meter in order to keep to the threshold.
If you want to switch off the system, switch off the speaker-system first in order to avoid acoustic shocks
on the speakers.

8. CLEANING AND MAINTENANCE

The operator has to make sure that safety-relating and machine-technical installations are inspected by an
expert after every four years in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are inspected by a
skilled person once a year.
The following points have to be considered during the inspection:
1) All screws used for installing the speaker-systems or parts of the speaker-system have to be tighly
connected and must not be corroded.
2) There must not be any deformations on housings, fixations and installation spots (ceiling, suspension,
trussing).
