frequencies. The Treble trim pot cuts/boosts by +/-10dB the
Microphone's high frequencies.
G
LevelGuard™ Indicator

activated.
H

ed. Fully Clockwise is off
I
Min. Mic Volume Trim Pot
Sets the desired minimum Paging Mic level, enabling the mic's
lowest preferred level to be set. This ensures that the main mic
level control cannot be accidentally set to totally turn off a page
into that zone.
J
Priority Switch
Selects whether Sources 1 and 2 are overridden by the Source 3
input.
K
Ducker
Ducking automatically decreases the level of the background
music when a page takes place. Set the Sensitivity control so that
the ducking occurs reliably whenever a mic page occurs. Set the
depth control to suit the application. Typical ducking would be with
the control straight up, letting through some of the background
music during a page. You can set the depth for full, minimal, or no
ducking of the music, as required.
L
Power Switch
Turns the Soundzone Controller on/off.
