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.
- 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
