3.2.2
Closing the battery compartment
Replace the anodized aluminum cover and tight the screw using a flat screwdriver.
NOTE: Certain D-Cells are longer than standard D-Cell batteries and slight difficulty may be
found in closing the compartment if such batteries are used. Your nearest SONOSAX
dealer or the manufacturer in Switzerland can provide assistance if a problem arise
due to this difference in length.
NOTE: A special screw with wings is also available if you don’t want to use each time a
screwdriver to open and close the battery compartment. Ask your nearest SONOSAX
dealer or the factory.
3.2.3 Batteries charger (optional)
An external NiCd or NiMH batteries charger is available as an option for the SX42. It can charge
simultaneously up to four 1.5V D-cells (LR20) or up to six AA (LR6) accumulators.
NOTE: It will take approx. 6 hours to fully recharge four NiCd or NiMH D-cell accumulators.
WARNING: Never attempt to charge alkaline D-Cell batteries!
3.2.4
Battery test
When the BATT push-button is depressed, the needle of the right level meter will indicate the
average charge per battery cell (minimum: 1V, maximum: 1.6V). In case of use with the external
power supply, the meter will indicate the voltage divided by four. For instance: a 1.5V indication
means that the external voltage is equal to 6V DC.
3.2.5
Low battery alarm
When the average charge per cell reaches 1.05V, the LED between the meters becomes red.
This alarm means that about 10 to 20 minutes are remaining before the mixer automatically
turns off. This auto-stop at 1V per cell will protect the accumulators from an excessive
discharge.
3.3
External DC Power Mode
The SONOSAX SX42 mixer can be powered from a 6V to 12V DC power supply capable of
delivering at least a current of 1A peak. The average power consumption is approximately 2 to 3
Watts, depending on microphones type and LEDs light intensity.
3.3.1 Fuse replacement
Some safety fuses protects the units from serious defects. As we are using multi-fuses instead
of traditional fuses, there’s no need to physically replacing it. The fuses will reset automatically;
if this is not the case, contact your nearest SONOSAX dealer or the factory.
