NOTES ON MEASUREMENT CONDITIONS
1. Pink noise signal, one Watt calculated using EVZmin, 4.
3.16 meter-measurement distance referred to one meter.
2. On-axis, one Watt calculated using EVZmin, 3.16 meter-
measurement distance referred to one meter, low frequen­
cies corrected for anechoic chamber error.
5.
3. This system rating patterned after the AES method for indi­
vidual driver, where the test signal is pink noise with a 6 dB
crest factor over the bandwidth of the system, with power
calculated using the EVZmin, for two hours.
This measurement made under the same conditions as Pres­
sure Sensitivity, but at rated power, and takes into account
any power compression effects due to non-linearities in the
system.
Distortion components invalid above 10 kHz. The distortion
at any given frequency may be found by graphically taking
the difference between the fundamental and harmonic, and
adding the number of Decibels which the harmonic has been
raised on the graph and apply the formula:
% distortion = 100 X
