Notes

1.Subject to half-space loading; measured with one-third octave frequency resolution in fixed ISO bands.

2.Measured as the ratio between the peak SPL and the A-weighted noise floor.

3.Nominal 8 Ω resistive load, pink noise, 100 V peak.

4.The unit is rated at 88 – 125 VAC and

182 – 235 VAC, 50/60 Hz, to satisfy EC standards for –10% to 6% AC line voltage.
