The ET150, 300 & 450 form the professional range
of audio frequency induction loop (AFILS) amplifiers
and are designed to provide studio quality sound in
an AFILS system.
The amplifiers have 3 inputs on XLR; 2 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 whilst
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 1u (44.5mm) high and a 19" rack
mounting kit is available. |
