TOA L-11S Line Matching Input with Mute-Receive

The TOA L-11S is a transformer-isolated line matching input module designed for 600-ohm applications, effectively minimizing ground loop problems when connecting remote equipment over distances greater than 15 feet. It features mute-receive capability, responding automatically to mute bus activation via a Mute SEND module or switch closure. By default, it supports both Mute Bus #1 and Mute Bus #2, with jumper settings that allow disconnection of individual mute buses. Equipped with a removable terminal block connector, the L-11S provides flexible and secure wiring for professional audio installations.
