Ensure mains power is disconnected BEFORE any connections are made to the Loop Amplifier.
Do not expose the Loop Amplifier, cable and accessories to rain or any other source of moisture.
Ensure that there is enough room around the Loop Amplifier for ventilation purposes.
Do not place the Loop Amplifier close to sources of heat, such as radiators.
United Kingdom connection to mains supply
This apparatus must be protected by a 3amp fuse if a 13amp(BS1363) plug is used. Be sure to replace the fuse
only with an identical approved type, as originally fitted, and to replace the fuse cover.
IMPORTANT:
The wires in this mains lead are coloured in accordance with the following code
Blue: Neutral Brown: Live.
If you need to change the mains plug supplied, the colours of the wires in the mains lead of this apparatus may
not correspond with the coloured markings identifying the terminals in your plug. Proceed as follows: The wire

SECTION ‘A’ - Installation/Connections
Place the amplifier in a convenient position near to your TV or Audio equipment.
Loop Cable
Run the loop cable around the room, leaving one end of the cable with the amplifier, return the other end of
the cable to the amplifier (complete the circuit). The cable may be tucked under the edge of the carpet, or
fixed to either a picture / dado rail, or skirting board (clips provided). Where the cable passes a door, either
fix the cable around the frame or tuck under the carpet.
Connect both ends of the loop cable to the loop cable connectors, one wire in each connector.
If excess loop cable is coiled it may affect the frequency response of the system. Excess cable may be cut
off as long as a MINIMUM of 11 metres (35 feet) is left connected to the amplifier.
or Loop Pad
Place the loop pad in a suitable position on the chair to be used for listening. Lay the connecting lead from
the Pad to the back of the Amplifier. Make sure that the connecting lead is kept out of the way to prevent
injury or obstruction.
Attach the connecting lead to the loop cable connectors, one wire in each connector.
Note:
When the loop cable connector buttons are pushed a hole will appear, push the bare wire into the hole. Ensure
that only the wire and not the plastic insulation goes in, then release the button.
Microphone
Plug the microphone lead into one of the microphone sockets on the rear of the amplifier. Place the
microphone on the TV speaker grille, or other sound source speaker, using one set of the Velcro™ pads
supplied. Peel off the backing paper and press the pad firmly into place. The microphone will then fasten to
it if lightly pressed in place. To remove the microphone pull gently and it will come free allowing its use
on other equipment.
Audio direct connection lead
As an alternative to a microphone input, the auxiliary input
“Aux In”
sockets may be used to connect to the
audio outputs of a television, radio or other audio and video equipment.
Using the
“Aux In”
sockets will result in a clearer sound from your system where a microphone may pick
up unwanted sounds in noisy rooms or if the volume on the TV etc needs to be turned off or down.
These connecting leads should be plugged in to the “Aux In Left/Right” Phono/RCA sockets on the rear of
the amplifier. If the leads provided with your system are not suitable, other leads are available from your
dealer.
The SCART or EUROconnector on a TV/Video may be used but an adaptor may be required if it is already
being used for connection to other equipment, consult your dealer for advice if necessary
On some TVs using the headphone socket turns off the internal speaker, on others there is a switch that
allows the speaker to be left on.
In addition, to either the microphone or direct connection lead described above, a microphone may be used to
monitor a doorbell or telephone or used by another person to talk to the person using the loop.
Plug in the mains lead into the socket on the rear of the amplifier and then plug into the mains outlet.
SECTION ‘B’ - Operating
Before switching on ensure that the
VOLUME
control is set to
MIN
and the
TONE
control is set pointing
upwards, halfway between
LOW
and
HIGH
. Ensure that the

AGC
and
PRIORITY
buttons are
‘Off’. These switches are pushed once for ‘Off’ and again for “On”. When the button is fully out it is ‘Off’.
Switch on the amplifier by pressing the
ON/OFF
button. The green power light will come on.
Set the television or other audio equipment to the normal listening level for other members of your household,
switch your hearing aid to the “T” or “MT” position.
Adjust the loop amplifier
VOLUME
control for the best results in your normal viewing position.
Adjust the
TONE
control to suit. In the “HIGH” position (fully clockwise), the higher frequencies will be
emphasised. In the “LOW” position (fully anticlockwise) the lower frequencies will be emphasised.
