Installation and Use Manual

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.
