3.1.3 Powering from external DC power supply
The SX-ES64 can be powered from any regulated external DC power supply or from an external battery bank
having a DC Voltage between 6 to18 volts. The DC source must be capable to sustain at least 20 Watts. The
average power consumption of the SX-ES64 is around 10 to 14 Watts.
The mixer is delivered with a universal AC/DC main adapter accepting a voltage range from 100 to 260V AC,
50Hz to 60Hz. Thus it can be used worldwide without any modification or adjustment.
The DC input connector for an external power supply is located on the rear panel of the mixer.
The mating cable connector is an XLR4-F
Pin 1 = GND or negative / Pin 4 = +6 to +18VDC positive
Connect the external DC power supply to the DC IN connector located on the rear of the mixer and then set
the switch to either [ECO] or [ON] to power-up the mixer. The first Yellow Led ON at the bottom of the left side
of the primary meter must light on steady. If the mixer does not power up, then:
¾ Check that the external power supply Voltage is between 6 to 18Volts DC
¾ Check that your power supply sustain at least 20 Watts.
¾ Check that the DC plug is correctly wired.
3.1.4 Automatic changeover of the DC power source
The internal DC/DC converter circuitry is designed to automatically changeover between the internal batteries
and the external DC power supply. You do not need to power OFF the SX-ES64 to change the power source.
While turning on the mixer, when an external DC power supply is connected and the batteries are installed,
the internal DC/DC converter will automatically switch on the external DC. If the external DC supply fails or if
the voltage drops below 5 VDC then the DC/DC converter will automatically switch to the internal batteries. In
this case the n this case the Red Led BATT will start flashing.
NOTE: the switch over is absolutely silent, no noise, pops or clicks during will be heard
