• XLR mic and one dual phono line input.

• Ideal for use in high-profile professional AFILS applications where minimal overspill and consistent loop coverage (i.e. no dead spots) is essential.

What is a phased-array induction loop system?
A phase-array induction loop system works by producing two AFILS signals that are 90° out of phase with each other. These signals are connected to two induction loops laid out in a special overlapping pattern (see inset diagram). The resultant magnetic field is evenly spread within the covered area and the field strength falls off very quickly outside the loop.

Outreach Plates

SigNET's Outreach Plate audio input extension system comprises a range of wall, ceiling and desk mountable single gang audio input plates specifically designed to increase the audio input capability of an induction loop system. Covering the most common variants of audio connector, they work by mixing the signals from various audio input sources into one balanced line level input which can be fed into the line input of a compatible amplifier.

Mountable on 25mm back boxes, each plate features a built-in mixer, pre-amp, input level control and balanced output. The fact they can be installed at the most convenient point on an installation overcomes the need for long and potentially hazardous microphone/audio leads.

Typically, up to 10 Outreach plates (any mix) can be daisy-chained to one balanced line level input with cable lengths of up to 100m easily achievable using standard two-pair audio cable with no recognisable degradation of audio signal quality.

Each outreach plate requires four wires, two balanced line (A +, A –), one ground (0V) and one power connection (12-32 V DC regulated). Click on the thumbnails below left for typical wiring schematics.
