reproductions of the oscilloscope measurements. The

kick drums on “Competitor A” were heavily distorted,

extremely harsh on the ears and harmful to the

loudspeakers as well. Its playback level fluctuated after

the kick drum, as was observed in the oscilloscope

measurement.

Competitor B’s output was considerably distorted when

louder notes were repeated. The amplifier’s limiter

kicked in on “Competitor C” after the kick drum beat.

The amplifier muted for a few seconds before returning.

This limiter may protect the amplifier from damage, but

this behavior is unacceptable in a live situation.

Yamaha’s T5n showed positive results in this test. The

T5n showed minimal limiting and had the most

headroom among the competitors. The amplifier’s

output did show slight distortion when levels were high,

but the playback remained musical and had the best

performance in this comparison.
