About Univox® DLS-33TV
Univox® DLS-33TV features automatic routing and connection to a TV via Scart
(Euroconnector), as well as two extra ports that can be connected to external microphones
or other audio sources, such as radio or MP3 player.
The DLS-33TV model can compensate for the audio time delay that ‘flat’ televisions oen
have.
The DLS-33TVpackage contains the following components:
• Loop amplifier with automatic Scart connection
• Loop pad/sofa loop
• Power adapter
Two pieces of 3M Scotchmate that can be used to attach the loop amplifier, to the rear side
of the TV, are also included.
Check before connection
First, check that the television works properly with the video/DVD/digital box/satellite
receiver. The devices to be connected to the television should be connected in series (see
figure below). If the television has multiple Scart connections, use number 1. The audio
source(s) in the middle of the series must have two Scart ports.
If the ports are connected correctly, the picture and sound emitted from the television
should automatically switch to the audio source you have chosen.

Connect the Univox® DLS-33TV
Connecting the loop pad/sofa loop to the amplifier
1. Place the loop pad on or under the seat cushion where you usually sit and watch TV.
Place the sofa loop cable on the floor/under the carpet around the sofa.
2. Lay the loop cable so that it reaches the amplifier, which should be placed behind the
TV. To reduce risk of tripping on the loop cable, run it along the wall or under a carpet.
Extension cables are available as accessories if necessary.
3. Connect the loop pad/sofa loop plug to the loop port (1) on the DLS-33TV.
4. Remove the Scart from the TV and connect it to the Scart socket (2) on the short side
of the DLS-33TV.
Connecting the amplifier to the TV
1. Connect the DLS-33TV’s Scart (3) to the TV’s Scart socket number 1.
2. If the TV does not have a Scart socket, connect a cable from the TV’s audio output to
any of the IN inputs (4) in the DLS-33(SC)/DLS-33TV(SC).
3. A third way of transmitting the sound from the TV to the DLS-33TV is to connect the
electret microphone 13A to any of the IN inputs (4). The microphone can then be
attached to the TV loudspeaker.
4. Connect the Switching power adapter’s wire to the amplifier socket marked 12V AC

5. Connect the Switching power adapter (6) to the mains outlet. The blue indicator (9)
will shine steady for a short while. Further information in the Indicators part.
6. If the sound and picture are not synchronised, this can be adjusted with the ´TV Sync´
control (10).
If desired, you can attach the amplifier to the backside of the TV using the 3M Scotchmate
included in the package. The actual placement though is not significant to the performance
of the amplifier. Select the T or MT setting on the hearing aid when you watch television.
Connecting other signal sources
To connect other signal sources like microphones, use the 3.5mm IN input sockets (4).
Adjusting the volume
If required, you can adjust the volume with the control (7) on the front of the amplifier.
This usually only needs to be done once, as the DLS-33TV is equipped with an automatic
volume control. Advertising spots can sometimes sound louder, which is normal.
Tone adjustment
If required, you can adjust the tone level, with the tone control (11) on the rear side of the
amplifier.
Indicators
The indicators for the power supply (yellow LED, 8) and loop (blue LED, 9) on the front of
the amplifier. The yellow LED indicates if the DLS-33TV is connected to a power supply
and the blue LED shows whether the loop is working (flashes along in pace with the audio
signal).
Maintenance
Under normal circumstances Univox® loop amplifiers do not need any special maintenance.
Should the unit become dirty, wipe the unit with a slightly damp cloth. Do not use solvent
or heavy cleaning agents.

Trouble-shooting
1. First check that the yellow power supply LED (8) is lit. If not, check whether the
adapter is connected to the mains power supply.
2. Check that the blue loop LED (9) is flashing in pace with the sound from the audio
source. If not, check that the volume level control (7) is turned up, that the loop pad/
sofa loop (1) and the audio source is connected (3)/(4). If the blue loop LED is still not
lit, the loop cable may be damaged.
3. Do not forget to select the T or MT setting on the hearing aid. If the indicator lamps are
on as they should be, there may be a problem with the hearing aid.
