The Bogen ATB-10 Attenuator regulates audio level over an entire 70V or 25V speaker array, and is capable of handling up to 10W loads (max). The attenuator installs into a Single -gang electrical box, features 10 attenuation levels, and is capable of bypassing attenuation altogether.
The ATP-Series of attenuators allows the production level of a network 25 of the V 70 or V loudspeakers that will be controlled by a wall-mounted volume control, without affecting the total amplifier volume settings. A jumper function eliminates the adjustment of the volume control knob when activated near 9-30 VDC. Applying 9V to C.C. 30V between the bolts labeled D + and d bridges the volume control function and provides full volume audio to the speakers.
