7.2 CONNECTION BETWEEN CONSOLE AND POWER SUPPLY
Attention! Before starting the power supply, please check that the line supply voltage
corresponds to that indicated in the rear of power supply.
The power cable features a SubD- 9 female connector (to link to the console) and a SubD-
15 male connector (to link to the power supply). The cable transfers also the signals
related to the Relais 1 - 2 (included in the power supply box).
7.3 SUPPLY VOLTAGES AND TROUBLESHOOTING
The mixer supply voltages are:
• + 48 V phantom voltage
• + 18V analogue section positive voltage
• - 18V analogue section negative voltage
• + 6 V digital section positive voltage
• -6 V digital section negative voltage
The correct operation of power supply is showed by the lighting 5 led (specific voltages)
on the front panel. If the console doesn’t work properly, please check the power
connection cable.
If the neon lamp placed inside the main switch is off (and therefore every led on the power
supply panel is off), please check the Main Fuse next to the line cord socket (1A T - 220
VAC / 2 A T, 110 VAC).
If one or more led on the panel of power supply are switched off (and therefore console
doesn’t work properly) please execute the following steps:
• disconnect the console from the power supply
• switch on the power supply
• verify that every led on the front panel switches on (except relais 1 and 2)
After that, if one or more led are still switched off:
• open the power supply cover
• verify the integrity of the 3 fuses placed on the power board and replace the burned
ones
• close up the cover through all the screws
• connect the line cord only
• switch on the power supply again and verify that every led on the front panel switches
on (except relais 1 and 2). Note: if the problem is still present, please contact Axel
Technology technical office
• switch off the power supply
• connect the mixer to the power supply
• switch on the power supply
• verify the correct console operation
7.4 RELAIS
The power supply features two built-in relais enabling by the mixer input modules.
The max electric load supported is 10 A, 220 V.
You can use the relais to drive the studio light indicator Mr.LIGHT by AXEL
TECHNOLOGY, showing that one or more microphones are ‘on air’.
The relais feature either Normally Open or Normally Closed contacts.
