Connecting signal source(s)
There are three different audio inputs. Two Mic/Line factory set (1) and (2) to line
sensitivity and one RCA line input (5).
Adjusting input sensitivity (Mic/Line XLR)
Set all adjustments to minimum position by turning the knobs counter clockwise all the
way to the end. Make sure that all connected audio sources (if there are any) except for
the one being adjusted are turned off. Turn on the signal source. If it is a microphone make
sure that somebody is speaking into it. If it is another type of source make sure program
material is playing.
Slowly adjust the sensitivity by turning the knob to the right of the XLR socket (3)
clockwise until the “In” LED (4) lights up. The sensitivity adjustment should be based on
the weakest signal, i.e. when adjusting for a microphone the weakest signal is the weakest
voice that will use the microphone. Do not increase the level beyond that the LED just
lights up. If the level is too high there is a risk of self oscillation.
Note
When using the RCA line input (5), no adjustment is required.
Connecting mains power
Connect the mains cable to the socket marked “110-240V AC” on the amplifier and to the
power outlet.
Adjustment of loop current level
Adjust the loop current level with the knob marked
(6) placed to the left of the loop
cable sockets (8). The LED indicator below the sockets indicates when current floats
through the cable(transmitting).
Use the testing device Univox Listener 2.0 (included in the case) to adjust the right loop
current level. Please consult the included user guide for instructions on how to use the
Listener 2.0.
