In general, three
types of output connector are used: SCART, Headphone or Phono. The
electrical character of each of these outputs is different and may even
vary between different models and manufacturers.
SCART Devices
Most modern TV sets
are fitted with a SCART connector, for use with audio and video.
TVL150, TVL250
and
TVL 350
are personal loops designed for use
with the SCART output.
The
SH1000/2000/3000
is a range of Silent Headphones for use with the SCART connector. All
these products may be plugged directly into the SCART connector on your
TV, without affecting the loudspeaker volume in any way.
When ordering your
SCART listening device, please specify the make and model number of your
televison set, and whether you wish to use the loop with SCART or Phono
connectors.
TV
Listening Devices for use with headphone output
Some modern TV sets
are still fitted with headphone sockets. However, the character of the
headphone output differs between the smaller portable TV receivers and
larger sets (21” screen and above).
The
TVL100
loop and
SH110/125
Silent Headphones are designed for use with 15” and other
smaller TV sets, in general, those which
specify a 32 ohm headphone impedance.
The
TVL125
TV loop is compatible with the headphone output of larger TV sets or, in
general, those which specify a headphone impedance of 32-600 ohms
impedance.
Both the
TVL100
and TVL125
plug directly into the headphone socket using extension lead supplied. Please note that, in some TV
receivers, the headphone socket will switch off the loud speaker. In
other sets, it is possible to control the headphone and loud speaker
volume independantly. For further details refer to your TV operating
instructions.
Home
Loop System
In the
HLS-30
system, a loop is installed around your living room and coupled with
your television via a special induction loop amplifier. Home Loop
Systems are also supplied with a microphone, to pick up conversation or
general room sound (such as telephone ringing).
The
CLS-30
is a home loop system incorperating a cushion loop, for use where it is
necessary to limit the range of the loop transmission, for example in
flats or residential accomodation.
