Models ATP10, ATP35
■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
