15) AC POWER SOCKET Make sure the unit is grounded; all three terminals of the AC power plug must be connected to avoid any injury to the user
or damage to the unit.
16) VOLTAGE SELECTOR The DV MICRO 50 features a 120V/240V Voltage Selector to use the amp in countries with different voltages, so
make sure the switch on the rear panel is on the correct voltage before connecting it to the AC power, and the fuse is the right value for that
voltage (This selector is not available on the 100V version).
Please change the voltage/fuse values label located near the voltage selector matching the voltage/fuse values when you need to change the
voltage of the unit.
17) FSW 1/4” MONO jack for connecting a SINGLE
footswitch to switch between Clean and Lead
channels.
18) GROUND LIFT Occasionally, when you’re
playing live and using the Line Out (18), the
soundman will detect a hum from your amp’s signal.
This is often due to a ground problem related to your
power source; You will likely eliminate this hum
simply flipping the GND Lift switch.
19) LINE OUT This balanced XLR output sends a
balanced signal to the mixing console or snake in
live and studio situations. The Line Out signal is
post-EQ and post-reverb
20) SPEAKER OUT The two speaker ouputs provided for speaker cabinet connections are wired in parallel and total minimum impedance load for the
amp is 4 ohms, so you can connect one or two 8 ohms speakers or only one 4 ohms speaker.
Use speaker cable (not instrument cable)..
