Notes
1. Subject to half-space loading; measured
with one-third octave frequency resolu-
tion in fixed ISO bands at 1 m.
2. Measured as the ratio between the peak
SPL and the A-weighted noise floor.
3. Nominal 8 ý resistive load, pink noise,
100V peak.
4. The unit is rated at 88125V and 182
235V, 50/60Hz, to satisfy EC standards
for 10% to 6% AC line voltage.
