6. Installation and operating instructions

6.1 Operating environment

1. The permitted ambient temperature range during operation
extends from -5°C to +40°C.
2. During storage or transportation, the temperature should be
between -15°C and +40°C.
3. If dew forms on the rear panel of the unit during
transportation or storage, allow the unit to acclimatise for
approx. 2 hours before use.
4. The speaker should be operated in a dry environment with
normal dust and moisture levels in the air. Do not expose the
unit to aggressive chemical liquids or vapours.
5. You can set up the unit in any position. Please make sure that
the heat dissipation outlet on the rear connection panel
(cooler) is always clear.

6.2 Optimised positioning of the Xperience system

SUB
The best position for the subwoofer is on the floor because this is
beneficial to bass reproduction. Bass signals are not dispersed in a
specific direction and the subwoofer does not therefore need to be
positioned centrally. It can be operated from one side of the stage.
TOPS
In order to produce the most even sound possible and achieve
maximum speech comprehension right up to the back rows at the
venue, the satellite speakers should be mounted as high up as
possible. You will require speaker stands here. The satellite
speakers should be clearly visible from every seating and standing
position. People or objects should not absorb the sound produced
by the satellite speakers.
You can also use the VXT-1/2 swivelling bracket to align the XT-1/2
correctly. The speaker stand and the swivelling bracket allow the
speaker to be mounted at a higher level and tilted downwards
(directed) towards the audience. The satellite speakers are like
ìheadlightsî shining on each member of the audience.
Monitor
When using the speaker as a ground monitor, lay it on the
chamfered side panel in order to face the XT-1/2 in an optimized
direction.

6.3 Preventing feedback
If a microphone is used, acoustic feedback may occur and cause the
speaker to produce high-pitched whistling noises.
To avoid feedback:
1. Make sure the person speaking stands behind the speaker
2. Never point the microphone directly at the speaker
3. Hold the handheld transmitter by the shaft. Do not cover the
microphone with your hand.
4. Should the speaker start whistling or screeching, turn the
VOLUME control down CCW until the feedback stops.

6.4 Protection and maintenance

To ensure trouble-free operation, never expose the system to
extreme sunshine, high temperatures, moisture or dust for longer
periods. Avoid operating the unit when subjected to large
vibrations and never remove the speaker grille. If the unit is faulty,
please contact the Fohhn Audio AG service centre. Do not open the
unit!

6.5 Preventing interference

Do not operate the system in the immediate vicinity of a radio or
television, as this may cause interference. When connecting to
other equipment, avoid so-called mains humming. If humming is
audible, however, this can be prevented by actuating the
ìground/liftî switch on the operating panel.
