Sound System

(502

A, 502B, 502C)

Full bandwidth pink noise is applied to the 502C Systems Controller and amplified to a level at the speaker terminals corresponding to the long-term rated power handling of the

speaker. The average sound pressure level (dB-SPL) is measured at 1 meter from the speaker in an anechoic environment. The peak maximum acoustic output is the peak SPL

possible with the maximum recommended amplifier power using musical program material.

Full bandwidth pink noise is applied to the 502C Systems Controller and amplified to a level at the speaker terminals corresponding to one Watt as referenced to the nominal

impedance. The average sound pressure level (dB-SPL) is measured at 1 meter from the speaker in an anechoic environment.

Full bandwidth noise, meeting the International Electrotechnical Commission standard #268-5, is applied to the 502C Systems Controller and amplified to a voltage at the speaker

terminals corresponding to the power handling of the speaker. The speaker must show no visible or measurable loss of performance after 100 hours of continuous testing.

International versions use XLR-type connectors.
