White PA System Volume Control For Adjust The Loudspeaker Output
Features:
PA (Public address) system use volume control with 24V relay. Background music system with voice alarm use attenuator with 24V relay. The volume controller is used to adjust the loudspeaker output in the room. 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. 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.
