Teleloop amplifiers
These three amplifiers covers up to 800m²  (8656 feet²) and have three balanced inputs on XLR; two dedicated microphones and one microphone or line selectable using a rear panel switch. User selectable phantom powering is available for the microphone inputs, enabled via a rear panel switch. The inputs are individually mixed before passing to the compressor limiter, which prevents loop overload while compensating for varying microphone usage.

All controls are recessed to prevent unauthorised access. Indication is provided for compression level, output current, loop status, and power supply. A loop current monitor socket is provided to allow headphones to be used to monitor the actual loop current. An audio output (post compressor) is provided for recording, with a slave audio in to allow cascading. A loop OK voltage is available to illuminate a sign showing correct loop operation. The units are all 1 u (44.5mm) high and a 19" rack mounting kit is available.

The PL amplifiers can be used in many different environments: churches, residential homes for the elderly, auditoriums, conference centers, and theatres.
