Mixer: Microphone Input Mixer; Expansion Module; Mains Fuse; Mains Connections - Optimus AXD-30 Operating Instruction

6.9. Mixer: Microphone input mixer

With the MIXER dipswitch in the OFF position, when the speech preference is activated, the MIC 1
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).

Expansion module

The amplifier includes a special place for installing the AXD series expansion modules (AXD-MP3, AXD-TEL...).
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 amplifier model.

Mains connections

On the rear panel there is a CEE22 plug base for the supply,
allowing connection to the mains supply by means of the cable
supplied with the amplifier.
These amplifiers are factory-prepared to operate with a mains
voltage of 230V AC. On request they can be supplied prepared
for operation with another voltage (115V CA).
N.B.: This unit must not come into contact with or be
splashed by water.
6.13. SURETY PAGING relay
connection
This connects when when the speech preference is activated.
They are used to activate external elements that have to be
activated at the same time that the speech preference is in
operation. The example in Figure 21 shows the connection
diagram in order to provide announcement security in the
attenuators.
