Adjusting Sound Level, Tone And Microphone Sensitivity - Univox CLS-1 User Manual

Microphone
If a microphone will be used, for example to make it possible for someone else to talk to
you while using the loop, it should be connected to the special microphone input (Mic). The
microphone shall be an electret type microphone (13T, see section Accessories).
It's also possible to pick up TV or stereo sound by attaching a special microphone on the
speaker grid (13A, see section Accessories). This microphone is normally connected to
the combined mic/line input (Mic/Line) but can also be connected to the special mic input
(Mic) if you want to adjust the input level. Take off the paper cover of the loose round
velcro pad and attach it to the speaker grid of the TV. Then use the attached velcro pad on
the microphone to attach it onto the speaker. The microphone will then automatically be
directed inwards and pick up the sound from the speaker. If you want to pick up the sound
of a surround system with the 13A microphone, attach it to the centre speaker.
Switched power supply
Connect the switched power supply to the output for mains power on the rear panel (12V
AC/DC). Finally connect the power supply to a power outlet.

Adjusting sound level, tone and microphone sensitivity

When all connections are done the indicator for mains power to the right on the front panel
should light steadily. The system is now active and ready to use. It's now time to make your
personal adjustments of loop current (volume), bass, treble and microphone sensitivity
to receive the best possible sound intelligibility. Start by putting your hearing aid/s in T
position.
Sound level
The sound level of the loop is adjusted with the volume control (thumb wheel) on the front
panel. The level can be adjusted up or down according to the conditions on site and to your
specific hearing deficit. Adjust the thumb wheel until you receive a comfortable level. It can
be recommended to make a note of the ideal level for future reference.
