Bogen ATP35 35-Watt Attenuator with Bypass

The ATP-Series of attenuators allows the output level of a network of 25V or 70V speakers to be controlled from a wall-mounted volume control, without affecting overall amplifier volume settings. A bypass function overrides the volume control knob setting when activated by 9V to 30V DC. Applying 9V to 30V DC between pins labeled D+ and D- bypasses the volume control function and provides full volume audio to the speakers. The ATP-Series attenuators feature etched faceplate markings.

Features:

• Adjusts loudspeaker output levels on 25V and 70V systems
• Bypass function allows important and emergency announcements to be heard at the highest level even if local attenuator volume is set low or off
• 2 models control up to 10-watt and 35-watt speaker systems
• 10 attenuation steps and an off setting
• Attenuation in 3 dB increments except for two lowest settings, which provide 6 dB reduction increments
• Mounts in standard electrical box, single (ATP10) or double (ATP35)
• Convenient pluggable screw terminal connections
