The APJ 3.5mm Mono Jack Plate is part of the Outreach Plate audio input extension system. This is a range of wall, ceiling and desk mountable plates. Their design is to specifically increase the audio input capability of any audio system. Covering the most common variants of audio connectors, they work by mixing the signals from various audio input sources into a single balanced line level input on a compatible amplifier.
- Accepts unbalanced electret microphones with 3.5mm mono jack plugs.
- Part of C-TEC’s patented ‘Outreach Plate’ audio input extension system
- Compatible with entire range of PDA102, 200E, Pro-Range and ML1 induction loop amplifiers.
- Can connect to any third-party audio or induction loop amplifier using an APV 24V 250mA power supply.
- Mounts on a 25mm standard UK single gang back box.

Each input plate features a built-in mixer, preamp, input level control and balanced output.
Typically, up to 10 Outreach plates (any mix) can be daisy-chained to one balanced line level connection. Cable lengths up to 100m are easily achievable using standard two-pair audio cable (i.e. Belden 8723).
Each plate requires four wires; two balanced line (Line/A +, Line/A –), one ground (GND) and one power connection (V+ = 12-32V d.c.).
Most of C-TEC’s PDA Range induction loop amplifiers are fitted with an Outreach connection socket as standard. For audio systems that do not have an Outreach socket, straightforward network connection can be achieved using an ‘APV’ 24V 250mA d.c. regulated power supply and an ‘APXO’ 3 pin XLR balanced line output plate.
