Connecting The loudspeakers

The LOCO-V2 is able to delivers up to 153 Watt at 4 ohm per channel, and the power amplifier
is protected against faults with short-circuit protection, thermal protection, as well as over­voltage, under-voltage, and DC protection. However be careful when connecting the wires.
Avoid short-circuiting the loudspeaker outputs because it can result in COMPLETELY DAMAGING
THE LOCO-V2.
