Attenuators For 25V/70V Speaker Line Models AT10A and AT35A
Installation and Use Manual
Speaker Installation
These 10-step plus “off” speaker attenuators allow the volume of a network of 25V or 70V speakers to be controlled from a remote location. The AT10A attenuator can handle speaker loads of up to 10W (max.) and the AT35A attenuator can handle speaker loads of up to 35W (max.). The AT10A fits into a single gang electrical box and the AT35A into a double gang electrical box. Volume reduction takes place in 3 dB increments except for the 2 lowest settings, which provide 6 dB reduction increments. A speaker “off” (“0”) position is also provided.
