Installation Instructions (Refer to Fig. 1 – Fig. 4)

1. Place the MegaLoopTM amplifier on top of your TV, Video Recorder or on a shelf. Make sure
there is a power socket available for the mains power adapter.

2. Plug the MegaLoopTM mains power adapter (B) into a standard electrical power socket, then plug
the power lead into socket (8) (Fig. 2).

3. Starting from the amplifier, run the loop wire (C) around the edge of the room. The wire can be
tacked up and over door frames if necessary. The wire can be tucked under the carpet or clipped
to the skirting board (Fig. 3). Make sure you leave enough wire to reach the amplifier.

4. Once a complete loop of the room has been formed, cut away any surplus wire making sure to
cut away the insulation from the wire ends. Clip each end of the wire into terminals (9) (Fig. 2).

5. If you are using a loop pad (Optional), clip the end of the lead into terminals (9) (Fig. 2). Make
sure the lead is placed carefully, so as not to cause a tripping hazard. Never run the lead

across the floor unless fully under the carpet. Always remembe r that loose wires are a
tripping hazard.

6. If your TV has a SCART socket connect SCART plug into the TV, connect the Phono/Phono lead
(I) to the SCART plug and plug the other end of the lead into the MegaLoop
sockets (10). If your TV has no SCART socket, but has audio output sockets connect the
Phono/Phono lead (I) to these sockets and plug the other end of the lead into the MegaLoop

Audio input sockets (10) 9 (Fig. 2).

7. With the power switched on at the wall socket press the Power Button (7) ON and the Power
“ON” Light (6) will give a constant Green light (Fig. 1).

8. How to test your installation: Make sure the Background Noise Control is at “N” position (1),
speak into the microphone connected to (12) in a normal voice, turn the Volume Control knob up
(2) and when the Red light (5) starts to flash you know that your system is working. Turn the
Volume back to your desired listening level.

9. Note: if the serial number is removed your warranty is invalid.

IMPORTANT

The MegaLoopTM microphone is very sensitive and too much volume out of the TV speaker can distort
the sound in your hearing aid when in the “T” position. The TV speaker’s volume should be set at a level
comfortable for a person with average hearing.
Microphone priority function
The microphone sockets (12) are marked (1) and (P). Socket No. (1) Is the standard socket to use when
connecting the microphone to a TV of Hi-fi speaker. Socket (P) stands for priority and gives a louder
signal than socket (1) this is very useful when using a second microphone for environmental sounds that
must be heard over and above the TV or Hi-fi.

Tone Control (3)

Adjust to suit your own hearing loss. Turning the control in an anti-clockwise direction tones become
lower. Turning clockwise the tones become higher. Most people like the Tone (3) at about 12 o’clock
position.

Headphone Socket (4)

Any standard headphones or Echo® NeckLoop can be connected. Always turn volume control (2) fully
anti-clockwise to “Low” position before connecting any headphones or Echo neck loop, then adjust up­wards to a comfortable sound level. If you do not follow these instructions you could damage your

hearing! Remember to turn your hearing aid to the ‘T’ position when using a neck loop

GAIN Control (11)

The factory setting for Gain Control Knob (11) is “Normal” position. This position is preset for most Scart
and Audio input signals.

Line Level Output (13)

The line output is a mono signal being the sum of any signals connected to the inputs fed post their gain
controls and the tone circuit and is fed before the master volume control.
Line output is a nominal level -6dBu with a 3.5mm female socket and the output impedance is 100 ohm.
