Induction loop amplifier for areas up to 700 square metres

This loop amplifier is suitable for connection to an existing public address system or as a stand-alone loop system.

The PLS-700 delivers an impressive 25Amps (65App) at 47Vpp to provide standard compliant area coverage up to 1800m² with the enviable, but essential
clarity of sound for intelligibility that you expect from this product. Housed in a rugged, convection cooled housing, the robust short circuit proof electronics provide quiet, reliable operation backed by our 5 year warranty. As all PLS’s, the PLS-700 is designed for enduring performance and simple installation.

The high output current of the PLS-700 facilitates the use of different loop configurations enabling greater flexibility in loop design to provide coverage
of large areas up to 1800m² (a maximum area coverage with 4 parallel multi-loops 1800m²) or compensation for signal losses caused by construction metal. The most suitable and practical configurations are single turn perimeter loops, 2 turn perimeter loops and multi-loops (with a perimeter loop 1:1-1:3 room ratio 700m²).

Engineering Simplicity
Engineering Simplicity is a Univox tradition; the PLS range is no exception and has been designed to simplify the amplifier selection, loop design and
installation processes. All amplifiers in the range are specified to operate with single and 2 turn loops using 2.5mm² cables. By installing a twin core multi-strand cable, the installer does not need to calculate cable impedance and he always has the flexibility to modify the performance of the system by:

With flexibility built in and assuming no fundamental laws of physics have been broken, the installer can be confident that the perimeter loop installation
will perform to standard without spending hours on measurements and calculations.
