• The volume controller is used to keep same output level for one same speaker line, because the end the speaker line signal loss is rather big, so its outputs is less, thus volume controller is added to the front of the line to lower the speaker output so as to keep the similar ambient output level for the all of the speaker in the same line.
• High level white UV-protected ABS material to integrate together with the white wall and architecture design.
• Built-in transformer to control the PA 100V line loudspeakers.
• With 10 levels of volume attenuator and one position of off.
• Surface wall mount or in-wall mounting box shall be purchased separated.
• With 24V relay is optional

The volume controller with 24V relay working principle: the relay from the amplifier or PA system will be input to this volume controller to override the output level to maximum when there is fire alarm or other emergency situation, by this way, some conference room even lower the volume or off the level during meeting even could hear the evacuation message during emergency.
