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.
Performance
Frequency Response: ±0.1 dB from 20 Hz to 20 kHz
at 1 watt.
Phase Response: ±10 degrees from 10 Hz to 20 kHz
at 1 watt.
Signal-to-Noise Ratio: A-weighted, better than 105 dB
below full bandwidth power. No weighting, better than
100 dB below full bandwidth power.
Total Harmonic Distortion (THD): Less than 0.05% at
full bandwidth power from 20 Hz to 1 kHz increasing
linearly to 0.1% at 20 kHz.
Intermodulation Distortion (IMD): (60 Hz and 7 kHz)
Less than 0.05% from less than 158 milliwatts to full
bandwidth power.
Damping Factor: Greater than 1,000 from 10 Hz to
400 Hz.
