input has priority over the remaining MIC (2,3,4,5) inputs, and these have priority over the AUX1 and
2 inputs (in the case of the AXD-30, MIC 1 has priority over MIC 2 and MIC 2 over the AUX inputs).
With the MIXER dipswitch in the ON position, the signals from all the microphone inputs (1 to 5) are
mixed, cutting off the signal from the AUX inputs when the speech preference is activated (in the case
of the AXD-30, MIC 1 and MIC 2 are mixed and cut off the AUX signal when the speech preference is
activated).

6.10. Oscillator adjustment

If the amplifi er has an oscillator circuit (optional circuit necessary for the monitoring of lines), the level of the oscillation
signal can be adjusted by means of this control. To make this adjustment, follow the steps indicated in the DALA-01/DA
card manual. The adjustment must be made with the corresponding loudspeaker line loaded.

6.10.1. Fitting the oscillator circuit

1. Disconnect the power supply of the amplifi er.

2. Remove the cover.
3. Fit the oscillator circuit, securing it by means of the two screws.
4. Connect the oscillator circuit to the input circuit of the amplifi er by means of the cable supplied together with the
oscillator.
5. Fit the amplifi er cover once again.

6.11. Mains fuse

This is located in the lower box of the power supply base.
There is also a spare fuse in the same box. The value of the fuse varies depending on the amplifi er model.
