Planning Advice
1. Any aperture in the window between public and service side will affect the
performance of the system.
The more the counter is enclosed, the better the system will perform.
2.The loudspeaker should be placed as close as possible to the listener´s ear.
The microphone should be as close as possible to the speaker´s mouth,
and as far as possible from the loudspeaker as circumstances allow.
3. Loudspeaker/public area (from the ground): side 1,50-1,60 m, overhead max.2,10 m
Microphone/public side (from the ground): 1,30 - 1,50 m,
minimum distance between microphone and loudspeaker: 0,5 m
4. Speaking distance from the microphone:
Service area: 10 - 20 cm
Public area:
• omnidirectional microphone: max. 50 cm
• directional microphone: max. 30 cm

Operaonal Setup/Service
Depending on the local acousc condions, it may be necessary to change the volume
seng range to avoid poor sound quality and feedback.
The following sengs set the maximum volume for the Service and Public area:
 Press the buon, the LED above the buon lights up.
 Disconnect the patch cable at console socket 1, wait unl all LEDs turn o.
 Press and hold the buon to reconnect the patch cable to socket 1 on the console.
 Keep the buon pressed (approx. 5 sec.) unl the LED above the buon ashes.
 Press the buon, the LED above the buon lights up.
 Use the and buons to set the maximum volume for an opmal sound quality at the
Service area.
 Press the buon, the LED above the buon turns o.
 Press the buon, the LED above the buon lights up.
 Use the and buons to set the maximum volume for opmal sound quality at the
Public area.
 Press the and buons to the same me unl LEDs above the buons ash briey once
to save the new values.
 Press the buon to exit the sengs, all LEDs will turn o.
Trouble shoong:
In case of interference, intercom components should be relocated to increase the distance from
sources of strong electromagnec radiaon.
