Attenuators with
Bypass for 25V/70V
Speaker Line
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 over-
rides 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
1
0-watt and 35-watt
speaker systems
•
1
0 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 (ATP
1
0) or
double (ATP35)
• Convenient pluggable screw terminal connections

Specifications
The speaker line attenuator shall be a Bogen model
(specify ATP
1
0 or ATP35), and shall permit setting the
output level at loudspeakers on a 25V or 70V line
without altering the amplifier volume setting. The
attenuator shall also have the ability to override the
volume control setting when activated by 9V to 30V
DC so that important and emergency messages will be
heard at all speaker locations.The attenuator shall pro-
vide a choice of
1
0 stops and an “off” position, and
shall be capable of controlling up to
1
0-/35-watt speak-
er systems.The attenuator shall measure (2-7/8” W x
4-5/8" H x 2-
1
/2" D for ATP
1
0 or 4-3/4" W x 4-3/4" H
x 2-
1
/2" D for ATP35), weigh (
1
lb. for ATP
1
0 or 2 lb.
for ATP35), and feature etched faceplate markings.
