Connect Loop Cable or Loop Pad to the amplier
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 Amplier
Direct audio connections
This is the preferred method of connecting your amplier to TV and other audio products. It will deliver the clearest sound
to you without background noise aecting the clarity. This amplier is tted 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. You may need to alter the settings of the digital audio out on
your TV to PCM so that the digital audio out signal matches the loop amplier.
Analogue audio connections use the red/white phono audio connectors (15) & (16) on the loop amplier . Analogue audio
is widely found on all types of equipment.
Up to 3 pieces of equipment may be directly connected to the loop amplier 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 nd that when plugging into a headphone socket on your TV
etc., this turns o the internal speaker. On some TVs there may be a switch or setting 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 other 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 amplier.
