Adjusting the Univox 2A Power Level to Match Your Loop

© May 2006 by Neil Bauman, Ph.D.

There are two lights on the right side of the Univox 2A. The yellow (right-most) one indicates that the Univox is connected to a source of power.

The green light to the left of it comes on when there is an adequate signal going into the loop (room loop or loop-pad).

The way you adjust the loop power correctly is to turn the power control knob on the left clockwise until the green light comes on. (I usually initially set it about half way to somewhere around 3), then slowly turn it counterclockwise until the green light begins to flicker. At this point you have the correct power going into your loop. The green light should flicker in unison with the louder parts of music or speech.

If you leave the power set too high, the Univox will get too hot. When the power level is adjusted properly, the top of the Univox should feel cool to warm to the touch depending on the size of your loop.
