8.4 Bypass Adjustments
The Bypass system has two adjustments: output level (all systems) and low
frequency and high frequency driver balance (for systems only equipped with the
optional Cat. No. 683 Electronic Crossover).
8.4.1 Before you Adjust
First, turn off the power to the CP500. Remove the Cat. No. 682 card, located in
position J2 (see Model CP500-SR Card Locations in Section 3). Set jumper J900
to the BCAL position.
Figure 8-1.
Cat. No. 682 - Set jumper J900 to the BCAL position.
NOTE
: Cat. No. 682 cards with revision numbers earlier than Revision 3 do not have this jumper. To adjust
level and low and high frequency driver balance with these older cards, see special instructions below.
Then, re-install the Cat. No. 682 card and turn on the CP500.
If you have a Cat. No. 683 Electronic Crossover card in your CP500, skip the
following sub-section and proceed to the section titled 8.4.3 Output HF/LF
Balance and Level Adjustments (Systems with Cat. No. 683 Electronic Crossover
Card). Special instructions for adjusting Cat. No. 682 cards with revisions earlier
than Revision 3 can be found in sections 8.4.4 and 8.4.5. (Revisions 2 and earlier
Cat. No. 682 cards do not have the jumper J900 to feed the pink noise calibration
signal into the bypass system.)
