Induction loop amplifier Pro Loop LOSplus
As a ready-to-connect system for supplying large rooms with inductive audio signals.
The powerful amplifier features Automatic Gain Control (AGC), which ensures stable sound with excellent speech reproduction even under difficult acoustic ambient conditions. To perform acoustic quality checks on the loop outputs A and B, the Pro Loop LOSplus has a monitor output for connecting headphones.
