these measure average sustained levels.

Amplifier power output changes depending on how many loudspeakers are connected.
Professional manufacturers typically quote output based on 8 ohms. Less reputable
manufacturers quote at 4 ohms to make their product seem more powerful.

This amplifier has an output of:
2 x 30w (sometimes referred to as 60w) @ 8 ohms (two loudspeakers connected)
2 x 60w (sometimes referred to as 120w) @ 4 ohms (four loudspeakers connected)
