a
Assumes insertion gain is within
b
The measurement range specification assumes that the input level is within
configuration. The actual O.33 test level range is –6 dBu to +14 dBu.
c
The value for other test levels can be calculated from the formula (–60 – Test Level).
d
Measured with Quasi–Peak response as per CCIR 468-4 recommendation. The measurement range can be determined
from the formula (70 + Test Level).
e
Weighting filter as per CCIR 468-4 recommendation.
