For normal two-channel operation, connect each speaker load across the output's positive and negative
terminals. Pay attention to speaker polarity; loudspeakers connected out of polarity degrade
quality and may be damaged as a consequence.
Keep the speaker cable leads as short as possible, and use a good quality stranded speaker cable. Do not
use shielded leads, such as microphone or guitar ca
of the amplifiers in two ways: by increasing the load impedance, and by introducing resistive power
losses.
WAR NING: To prevent from electric shock, do not operate the amplifier with any of the
c onductor portion of the speaker wire exposed.

It is alwa ys a good idea to turn down the gain controls during power-up, to prevent speaker
damage in case a high signal is present at the input.
