Since the companies founding in 2003, one of our key areas of business has been induction loop systems. From standard perimeter loops through to low-spill phased arrays. www.inductionloop.org
Churches are a market like no other. They way they use their systems and the equipment needed, along with challenging building designs and often less-than-ideal acoustic spaces requires a specialist company to ensure results which are effective, but not intrusive. www.soundadviceforchurches.co.uk
A1706 60W Mixer Amplifier

Versatile desktop induction loop assistance for hearing aid wearers.
This induction loop unit is powered by a rechargeable battery and is always ready for immediate use if charged.
No installation works are required.
The microprocessor-controlled Portaloop features the latest induction loop technology with automatic gain control, noise 'gating' to improve reception of speech and automatic standby mode to conserve battery life.Once switched on, the unit can be left on standby all day and re-charged at night, or plugged in to the mains - ready and available for immediate use.
Hearing aid wearers only have to switch their device to the 'T' or telecoil position to hear speech clearly, with little or no background noise.
The Portaloop can be used on a one-to-one basis or in meeting room locations. The electro-magnetic field extends to a maximum of 1.5M diameter from the unit.
- Easy to use - No installation works required·
- Simple, neat solution - No trailing wires or parts to lose
- Neat and compact - Unobtrusive, effective, inclusive
- Incorporates microphone, amplifier, induction loop aerial and rechargeable battery system
- Simple Status Indication
- On/Off switch and dual colour LED light on top of unit
- Flashing light indicates when the unit is receiving speech or other sound
- Red light indicates when the unit needs recharging
- Constant light is illuminated during recharging
- Dimensions Width - 170mm Height - 180mm Depth -65mm
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 mic/line level input.
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.
Attractive free-standing design (optional wall and 19" rack-mounting kits available)
Coverage Square room 200m2 - Rectangular room 240m2
Two XLR 3 pin input sockets - one balanced mic. and one mic/line, both with 11V phantom power
'Outreach' input allows the connection of up to 10 additional mic. or line level inputs via a series of separately available single gang connector plates.
Adjustable drive control allows the loop current to be adjusted to suit a room's characteristics.
Metal compensation control helps offset the frequency response problems associated with excessive metal in a building.
3.5mm headphone socket allows true monitoring of the output signal
All models designed to meet or exceed the requirements of BS7594 and EN60118-4 when correctly installed
Listenor PRO Amplifier System
The microphone of Listenor Pro can be placed in a raised position on a nearby surface using the belt clip, or held in the hand and pointed towards the sound source.
There are a number of optional accessories listed below which can help those everyday listening requirements: headphones or an inductive loop for use with telecoil-equipped hearing aids, the Listenor Pro telephone kit provides cables to connect to landline telephones for home or office use. Listenor Pro amplifies the caller’s voice and you can continue to speak using the telephone handset.
