• Dip switch no. 1 sets the gate threshold. In the "OFF" position, the gate threshold is high and the
microphone will not come on unless the user talks into it from a very short distance. As soon as the
microphone is open, the threshold will be automatically reduced by 6 dB so the microphone will not
switch off if the talker speaks more softly or moves away from the microphone.
In the "ON" position, the gate threshold is 6 dB lower than in the "OF" position. Again, as soon as the
microphone is open, the threshold will be automatically reduced.
• Dip switch no. 2 toggles the time the microphone remains open after the talker stops talking between
12 seconds ("OFF") and 6 seconds ("ON").
• Dip switch no. 3 activates and deactivates the microphone Automute function. In the "OFF" position,
the microphone will be muted automatically after the delay you set with dip switch no. 2.
In the "ON" position, the microphone will not switch off unless the delegate presses the PTT switch.
• Dip switch no. 4 allows you to switch the Microphone Station out of the NOM Limitation bus, so this
is an important option for Chair Stations. In the "OFF" position, the user can switch their microphone
on at any time, no matter how many microphones are open already.
In the "ON" position, the microphone can not be activated unless the number of open microphones
is lower than the number set on the Base Unit.
• Dip switch no. 5 toggles between Direct and Voice Activation modes. In the "OFF" position, the dele-
gate can only switch the microphone on and of by pressing the PTT switch.
In the "ON" position, the delegate may use the PTT switch, too. However, if the Base Unit operates in
Voice Activation mode, the microphone will come on automatically when talked into.
• Dip switch no. 6 allows you to switch the Microphone Station out of the priority mute bus. Set dip
switch no. 6 to "OFF" on all important Microphone Stations (chairpersons and their deputies,
important delegates) to "OFF" to make sure these microphones will remain open even if the chair-
person presses the priority button.
In the "ON" position, the microphone will be muted whenever the chairperson holds down the priority
button.
• Dip switch no. 7 activates/deactivates the Voice Zoom function. In the "OFF" position, Microphone
Station gain will be increased automatically if the talker speaks more softly or moves away from the
microphone while the signal will be compressed or even limited if the talker speaks very loud or too
close to the microphone.
In t he "ON" position, Microphone Station gain will remain constant.
• Dip switch no. 8: In the "OFF" position, the last volume setting for the built-in loudspeakers and head-
phone outputs will be saved and remains in memory even after powering down.
In the "ON" position, the volume of the loudspeakers and headphone outputs will be automatically set
to maximum upon powering up.
The trimmer pot P3 sets the Microphone Station output level. The output level has been factory
preset for optimum matching to the CS 2 BU Base Unit. Be sure not to change the setting of P3
because mismatching may cause system malfunction.
3. Replace the dip switch cover.
1. Cut an installation opening into the tabletop, using the template in fig. 13.
2. Insert the Microphone Station into the opening and fix the Microphone Station with four suitable
screws (not supplied)
