of current; 220 and 240 VAC units draw up to 7 amps.
4 Specifications
The following applies to units in Stereo mode with 8 ohm loads and
an input sensitivity of 26 dB unless otherwise specified.
Standard 1 kHz Power:
refers to maximum average power in watts
at 1 kHz with 0.1% THD.
Full Bandwidth Power:
refers to maximum average power in watts
from 20 Hz to 20 kHz with 0.1% THD.
120 VAC, 60 Hz Units:
refers to amplifiers with dedicated trans-
formers for 120 VAC, 60 Hz power mains.
International Units:
refers to amplifiers with special multi-tap trans-
formers that make them configurable for several AC mains voltages
and line frequencies.
