AT-Series of attenuators allows the output level of a network of 25V or 70V speakers to be controlled from a wall-mounted volume 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.
