If you do not intend to use your unit for any considerable length of tim e, unplug the unit. Do not pla ce f urniture or other hea v y o b jects o n the cord , a nd try to avoid dropping heavy objects on it. Do not tie a knot in the power cord. Not only could the cord be damaged, but a short circuit could also be caused with a consequent fire hazard.

DAMAGE IN TRANSIT WILL NOT BE COVERED BY WARRANTY.

WATTS

The most consistent standards for me as u ring w a tts a re “Program Po w er” and “RMS” because these measure average sustained levels.

Amplifier pow er o utp ut changes depending on how ma ny loudspeakers are connected. Professional manufacturers typically quote outpu t based o n 8 o hms. Less reputable manufactur ers q uo te a t 4 ohms to make their pro duct seem mo re po werful.

This amplifier has an output of: 2 x 50w (sometimes referred to as 100w) @ 8 ohms (tw o loudspeakers connected) 2 x 100w (sometimes referred to as 200w) @ 4 ohms (four loudspeake rs co nnected)
