Attenuators for 25V/70V Speaker Line, White The AT-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. The AT10A can
handle speaker loads of up to 10W and the AT35A can handle speaker loads of up to 35W. Volume
reduction takes place in 3 dB increments except for the two lowest settings, which provide 6 dB reduction increments. These rugged attenuators have 10 levels of sound control, plus an off setting.
