7.3.2. Tweeter-Module Schematic:
The following diagram shows the schematic of the tweeter-module shading network. All five shading
banks are shown. Banks 1 and 2 are shaded by series-parallel network combinations. Banks 3, 4, and 5
are shaded with resistive attenuators. Refer to Appendix 2: CBT Theory of Operation for more information
about CBT shading and the CBT36 shading implementation.
The schematic shows the colors of the insulated jumper wires and where they connect. Also shown are
the locations of the U-jumpers and resistor-lead connections which are shown in dashed lines. The
physical wiring itself is shown in the following wiring diagrams and photos.

TEPS
:
The next sub sections show where each wire and jumper are located on the tweeter modules. Install all
24 AWG wires for
BOTH
panels prior to soldering, perform an inspection and then solder.
As mentioned
before, it’s much easier to correct wiring errors if the connections aren’t soldered!
For each panel we suggest installing the wires in the following order:
1)
Series “U”-shaped jumpers (10 each).
2)
4.5” RED jumpers (5 each).
3)
4.5” BLACK jumpers (5 each).
4)
Resistors with RED and YELLOW jumpers.
5)
Remaining RED and BLACK bank jumpers.
For wiring reference, the following wiring diagrams, and photos show each of the five tweeter shading
banks and where the individual jumpers and colored wires are connected. After all wires have been
attached, you should also refer to the full-size fold-out wiring diagrams and rear-panel photos at the end
of this manual as an additional wiring reference.
