Mounting and placing
UniVox
TV-200 is either wall-mounted, see screw holes on the bottom
®
(page 10), or placed on a flat and stable surface. The wire between the loop
figuration and the loop amplifier should not exceed 10 meters and the wires
should be paired or twisted.
Important!
The amplifier normally runs hot during use and needs free space for cooling
through the top and bottom. To avoid possible fire or discolour, the amplifier
must be kept at a distance from fragile and easily flammable materials.
Preparatory connections
1. Connect the loop wire to the amplifier's connector terminal marked
Loop.
2. Connect a suitable input signal source.
3. Connect the amplifier to mains or a 12-24V DC power source. Yellow
LED is lit.
Default settings
1. Check that there is an input signal (green LED In is lit).
2. Adjust the microphone sensitivity (see drawing) so that the green LED In
is lit during program peaks.
3. Adjust the magnetic field strength by turning the control knob Loop so
that program peaks occasionally reach 400mA/m. Use only UniVox
FSM field strength meter with RMS measurement and 125ms integration
time. Check the sound quality with the loop receiver UniVox
In certain cases it might be suitable to increase the treble. The treble
control can be found inside the TV-200 (the only control knob inside).
When increasing the treble there is an increased risk of self-oscillation
and distortion.
