Connect Loop Cable or Loop Pad to the amplifier

When the loop cable connector (11) buttons are pushed in a hole will 
appear. Push the bare wire into the hole. Ensure that only the bare 
wire and not the plastic insulation goes into the hole, then release 
the button to lock the cable in place.

Connect Audio Inputs from TV or other Audio Source to Loop Amplifier

Direct audio connections

This is the preferred method of connecting your amplifier to TV and other audio products. It 
will deliver the clearest sound to you without background noise affecting the clarity.

This amplifier is fitted with digital and analogue audio inputs.

Digital Optical TOSlink and Coaxial outputs are found on most current TVs and Audio equipment. 
These connections (13) & (14) will provide the clearest sound input to your system.

Analogue audio connections use the red/white phono audio connectors (15) & (16) on the loop 
amplifier.  Analogue audio is widely found on all types of equipment.

Up to 3 pieces of equipment may be directly connected to the loop amplifier at any one time. 
One digital using either TOSlink or Coaxial but NOT both at the same time and one or two 
pieces of equipment with analogue audio output.

If the TV or other sound source does not have a set of phono connectors then use the SCART 
or jack adaptors accordingly to connect the equipment. If you use the jack adaptor you may 
find that when plugging into a headphone socket on your TV etc., this turns off the internal 
speaker. On some TVs there may be a switch that allows the TV speaker to be left on.

Microphones

If a direct connection is not possible then a microphone can be used to pick up the sound 
from a TV or other loudspeaker. Microphones can also be used for someone to speak directly 
into the loop system so they can speak directly to the hearing aid user while they listen to 
TV. A microphone can be used at the same time as the line inputs to monitor environmental 
sounds such as a doorbell or telephone bell.

A microphone can also be used in either a classroom or other public speaking situations.

One or two microphones can be used at the same time using sockets (18) & (19).

A priority function also exists when using a microphone in channel B (19) to override sounds 
from any other input to the loop amplifier.
