TEST PROCEDURES

4.4 Apply a 100Hz, 500mVrms signal to
the input of the 802C.

4.5 Reference a dB meter to the 302 AMP
output jacks (while in the Bi-Amp mode).

4.6 Refer to the frequency response table
below and verify the response of the unit.

6. Noise Test

6.1 All noise measurements are ANSI
A-weighted true rms, with the inputs
shorted.

6.2 Refer to the table below for the proper
noise levels.

5. Distortion Test

Note: Total harmonic distortion must be
measured in all modes to assure proper
operation.

5.1 Apply a 750Hz, 5Vrms signal to the
input of the 802C.

5.2 Refer to the table below for the distor-
tion specification for the corresponding
mode being tested.

Note: For the Bi-Amp 302 reading the
input signal should be a 100Hz, 5Vrms
signal.
