Notes on Measurement Conditions
1. Band-limited pink noise signal, one watt
calculated using E

/Z
min
, 3.16-meter measure-
ment distance referred to one meter.
2. On-axis, one watt calculated using E
2
/Z
min
,
3.16-meter measurement distance referred to
one meter, low frequencies corrected for
anechoic-chamber error.
3. This system rating is patterned after the
ANSI/EIA RS-426-A method where the test
signal is pink noise with a 6-dB crest factor
over the bandwidth of the system, with
power calculated using E

/R
E
x 1.15, for 8
hours.
4. This measurement made under the same
conditions as pressure sensitivity, and takes
into account any power-compression effects
due to nonlinearities in the system.
5. The distortion at any given frequency
may be found by graphically taking the dif-
ference between the fundamental and har-
monic, and adding the number of decibels
which the harmonic has been raised on the
graph and apply the formula: percent dis-
tortion = 100 x 10
(-difference in dB/20)
6. The use of Vari Intense

horns is protected
by U.S. patent # 5,020,630.
