TEST PROCEDURES

4. Bi-Amp Frequency Response

Note: This test is performed with both the
802 AMP and the 302 AMP output jacks
used at the same time.

4.1 Apply a 750Hz, 500mVrms signal to
the input of the 802C.

4.2 Reference a dB meter to the 802 AMP
output jacks (while in the Bi-Amp mode).

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

3. 302 Passive Frequency Response

3.1 Apply a 750Hz, 500mVrms signal to
the input of the 802C.

3.2 Reference a dB meter to the 302 AMP
output jacks.

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

2. 802 Full Range Frequency Response

2.1 Apply a 750Hz, 500mVrms signal to
the input of the 802C.

2.2 Reference a dB meter to the 802 AMP
output jacks.

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

1. Mode Indicator Test

1.1 Depending on the output jack configu-
ration (see top cover diagram on page 17),
equalization curves and output vary. You
must test all modes of the 802C to assure
proper operation.

1.2 Perform the test below to verify that the
mode select operation is working properly.

Note: You can insert one or both of the
