INTRODUCTION

The VC3xx2 Series are 100 Volt wall volume controllers whereby the volume for 100 V loudspeakers can be

adjusted in 11 steps of 3 dB. They feature a slim and good looking design and are constructed out of sturdy

ABS, making them suitable for big projects in industrial environments as well as standard home interiors.

An integrated 24 Volt relay allows bypassing of the volume controller in priority situations, making sure the

message is always clearly heard at maximum volume. Connections are made using screw terminal blocks,

and flush and surface mount boxes (WB3102) are separately available.

Use only Hi-Z 100 V loudspeakers. Total loudspeaker power shall not exceed program power handling of

the volume controller.

2-WIRE CONNECTION

4-WIRE CONNECTION

The 4-wire connection requires an amplifier with 24V output and a volume controller with a priority relay,

COM12 and COM24. In the 4-wire connection, the volume controller is set to the maximum during an

announcement from the connected microphone. Please note that when the volume controller is set to 0

both background music and emergency announcements are muted.
