DEFINITIONS
Rated conditions
• Nominal input voltage at input under test
• master fully clockwise
• high / low and colour off
• bass / middle / treble / pan centered
• effects level fully anticlockwise
• gain of unused inputs fully anticlockwise
• gain of input under test adjusted to nominal output voltage
at line out. (This condition corresponds by design to the rated
output power.)
Nominal input voltage: Standard condition for specifications,
if not stated otherwise.
Minimum input voltage: Input voltage required for nominal out-
put with maximum gain and volume settings.
Maximum input voltage: Input voltage that does not cause
distortion more than rated THD+N, suitable control settings
provided.
Nominal output voltage or power refer to rated conditions.
THD + N: Total harmonic dist noise, with input voltage
reduced by 10 dB after setting up rated conditions.
Signal / noise ratio: Ratio of output voltage at rated conditions to
output noise voltage with input shorted.
Equivalent input noise voltage: Noise voltage at loudspeaker ter-
minals divided by gain of amplifier. Input shorted after setting
up rated conditions.
Residual noise: Output noise with minimal gain and volume
settings.
Adaptive limiter: Adaptive with respect to power supply.
Maintains constant headroom regardless of power supply
fluctuations.
General: Signal voltages are RMS values. Test signal sine 1 kHz
sine unless stated otherwise. Noise measured from 20 Hz to 20
kHz. Noise stated for a specific input implies that all other inputs
are not used. Sound pressure level (SPL) based on
loudspeaker specification by manufacturer.
Specifications and appearance subject to change without notice.
