802C SYSTEM CONTROLLER
TEST PROCEDURE
NOTE:
For Bi-Amp Modes, you MUST have
jacks inserted in BOTH 802 and 302 outputs.
Measure where indicated.
4. 302 Bi-Amp Mode:(302 & 802 JACKS)
High Frequency: (Measure at 802 outputs)
The 802C functions as three equalizers and
an
electronic crossover network. Depending
on
jacking configuration, equalization curves
and outputs vary. You MUST test all modes
of the 802C to assure proper operation.
