Verification of the specifications is accom-
plished by standard procedures with the
exception of the “noise” and “THD” mea-
surements. Since the outputs are combs,
P1 (stereo width) should be rotated to give
the maximum possible output for the
frequency chosen. This measurement
becomes the reference level below which
the noise should measure 70dB. THD
should be measured in the same way. Specifications
