2. Installation
This device operates with a dangerous voltage of 115 V or 230 V. Never attempt to open the de-
vice yourself and never insert anything into the air vents! You could receive a severe electrical
shock!
Important notes
• When installing the induction loop amplifier, make sure that the air intake at the top and the air
outlet at the back are not covered or blocked in any way.
• It is normal for the amplifier to become warm when in operation. It is important that air is able to
circulate freely around the device. If the air circulation is impeded in any way, the device will
require forced cooling.
• Make sure that the amplifier is mounted securely and will not slip or fall.
• To prevent any damage to the internal components, you should not screw screws or drill holes
in the device enclosure.
• Make sure that the voltage indicated on the rear side of the device is the same as your local
voltage.
• All connections should be made by a qualified technician only and only when the device is
switched off.
Tips
1.
Before beginning to install the device, you should be sure to check the area for any magnetic
interference. Such interference can have a negative affect on the operation of the device or
make it impossible altogether. Interference can be caused by transformers, power lines, rein-
forced concrete or floor heating systems.
2.
If the loop is to be installed in a pipe, then make sure that the pipe is made of plastic.
3.
Do not lay any input signal cables parallel to the loop wire.
4.
Avoid using dynamic microphones inside the loop. Always chose symmetrical electret or capa-
citor microphones to prevent acoustic feedback.
5.
If it is not possible to lay the loop in a circle or in a "figure 8" (double circle), then a special loop
design calculated by an experienced technician will be necessary. (Please do not lay any comb
or meander structures!)
