Induction loop amplifier Pro Loop C
The Pro Loop amplifier family, reliable and time-tested, is designed for professional use in private and public facilities where particularly high reliability with extremely safe operation is required.
With 100 per cent short-circuit-proof amplification, with switchable, balanced XLR(F) inputs and highly stable output powers, the Pro Loop C meets these requirements.
The Automatic Gain Control (AGC) ensures a constant field strength and produces a stable sound with clear speech emphasis even in acoustically difficult environments.
Induction loop case
The induction loop case contains a complete portable loop system including:
- Pro Loop C induction loop amplifier
- Two cable drums with 20 metres of induction loop cable each.
- Measuring device Pro Loop FSM and LPU-1 induction loop receiver
The system is easy to use and ready for operation »in no time« - ideal for temporary installations.
