Signet ML1/K Counter Induction Loop Afils Kit
SigNET’s new ML1/K counter induction loop Afils kit is ideal for use in post offices, banks, building societies, ticket offices and reception areas. Comprising a compact wall-mounting double gang induction loop amplifier, a self-adhesive microphone and pre-formed counter loop, it can generate a loop listening field of approximately 1.2m2 making it ideal for ticket booths, desktops and tables. In addition to its 3.5mm microphone input, the ML1 amplifier also features a balanced line level input, loop strength, input peak and mains on indicators and a selection of user and engineer adjustable controls. As well as being used as part of the ML1/K counter loop system, the ML1 is capable of covering rooms up to 20m2 (approx. 4.5m x 4.5m) using a loop made from four core burglar alarm cable wired as four turns.
- Requires no specialist audio install experience
- Complies with DDA requirements BS8300
- Perfect for counter/desk applications
- Can also be used as small room loop up to 20msq
- Fits into double gang electrical back box
- Complete kit provided. Nothing else required.
- Comprises, Loop amp, microphone, loop cable and loop ID sticker.
- 5 Year warranty
- Excellent audio performance
- Made in UK
Mains voltage - 230V ac ± 10%
Max. primary current - 45mA
Fuses A non-replaceable thermal fuse is located in the transformer The ML1 requires fixed mains wiring fed from a 3A fuse spur located no more than 3m from the amplifier. The amplifier is designed to mount on a standard UK 25mm double gang back box.
Input connector - 3.5mm mono jack (located on the front of the ML1)
Input Impedance - 600
Sensitivity - 2-5mV (-46dB to -50dB)
Phantom - +9V
Input connector - Screw terminals (located on the rear of the ML1)
Input impedance - 10k
Sensitivity - 0dB (300mV rms to 1.5V rms)
Should additional inputs be required, the ML1 is compatible with SigNET’s ‘outreach plate’ input extension system. This allows up to 10 extra mic or line level inputs to be daisy-chained to the ML1’s line input. See our separate datasheet for details.
Type - Current mode
Loop connector - Screw terminals
Cable - For counter loops, use the pre-formed TX2 counter loop supplied in the ML1/K kit (see fig.1) For rooms up to 20m2, use four core burglar alarm cable wired as four turns (see fig. 2)
Loop coverage (counter loops) - 1.2m2 (using TX2 counter loop)
Loop coverage (small rooms) - Up to 20m2 i.e. 4.5m x 4.5m (using four core burglar alarm cable wired as four turns)
Loop drive current - 250mA average, 600mA max.
Loop impedance - 0.2 to 2
Bandwidth - 40Hz to 8kHz
Input stage dynamic range - 33dB
Distortion - <0.5% THD
The ML1 includes an amplitude compression stage that limits overload and has a dynamically variable ratio from 1:1 to 10:1
