Idle
Thermal loss at idle or with very low signal level.
1/8 Power
Thermal loss at 1/8 of full power is measured with pink noise. It approximates operating with music or voice with light clipping and represents the
amplifier's typical "clean" maximum level, without audible clipping. Use these figures for typical maximum level operation.
1/3 Power
Thermal loss at 1/3 of full power is measured with pink noise. It approximates operating with music or voice with very heavy clipping and a very
compressed dynamic range.
Full Power
Thermal loss at full power is measured with a 1 kHz sine wave. However, it does not represent any real-world operating condition.

Specifications are subject to change without notice.
