AUDIOropa PRO LOOP NX3 Bedienungsanleitung Seite 18

4.4.5 Power on / off
The unit does not have a mains switch. When the mains cable is connected to the amplifier
and a live socket, the amplifier switches on. The power LED (see figure 4.2: 9) lights up
and indicates the switched-on state.
To switch off the unit, the power supply must be disconnected. If necessary, disconnect
the mains plug from the socket.
4.4.6 Display row »Compression dB« (Figure 4.2: 4)
These LEDs indicate the level reduction in dB, in relation to the input signal.
4.4.7 LED »Loop Current« (Figure 4.2: 8)
This red LED lights up when the loop is connected and an audio signal is present.
If the loop is interrupted, short-circuited or the loop resistance is not between 0.2 to 3
ohms, the »Loop Current« LED is not displayed.
5. Audio input
5.1 Sensitivity (figure 4.2: 1, 2, 3)
The input levels of MIC1/LINE1, MIC2, LINE2 and LINE3 can be adjusted according to the
connected audio source.
5.2 Analogue AGC (Automatic Gain Control)
The incoming audio level is monitored by the unit and automatically reduced using ana-
logue amplifier technology in the event of an overloaded input signal. This ensures safety
against feedback problems and other unwanted effects.
