TOA's volume control attenuators provide precise level adjustment to single or multiple speaker lines. They are available in 25W or 100W models with a Decora-style wall plate. AT-100EMG is equipped with a 24VDC@15mA relay for applications that require emergency and paging signals to bypass/override the attenuator. AT-10K is a 10k ohm linear taper control for single-point remote level adjustment of voltage controlled amplifiers such as TOA's M-900MK2, A-900MK2, M-9000M2, A-9000M2, A-700, BG-2000, BA-200, AV-20D series mixers/amplifiers.
