SigNET's new range of professional current mode audio-frequency induction loop amplifiers offer outstanding sound quality at a
competitive price. They are ideal for use in large prestigious applications such as theatres, churches, cathedrals, cinemas, large conference halls, etc., where first class sound and unrivalled reliability are a must.

Each amplifier includes one balanced microphone input and one switchable balanced mic. or line level input, both of which will accept standard 3 pin XLR connectors. Optional 11V phantom power is also available on both inputs to allow the use of electret or condenser microphones.

By popular demand, each amplifier also features a four-way ‘Outreach' input offering full compatibility with SigNET's unique Outreach Plate audio input extension system. This system allows the connection of up to 10 additional microphone or line level inputs via a range of specially designed single gang connector plates.

The pre-amplification stage of each amplifier utilises an advanced signal processing system that allows tight control over the audio signal without any degradation of output quality. A metal compensation control is also provided to help offset the frequency response problems associated with the excessive metal content of some rooms.

Other features include three level controls (one for each input), a loop drive control, an output current meter and a ‘compression' activity display giving visible indication of the amplifier's compressor.
