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.
