6) After load capacity is determined, refer
to Figure 4 to determine the proper
multiplier setting for all the volume
controls.
NOTE: Multiplier setting #1 refers to
jumper position X1, multiplier setting #2
refers to jumper position X2, multiplier
setting #3 refers to jumper position X4
and multiplier setting 4 refers to jumper
position X8 (see Figure 6).
7) Position the jumper plug on the two
pins relating to the appropriate
multiplier setting (X1, X2, X4, or X8)
see Figure 6).
NOTE: Although there are jumpers for
each speaker's output, in most cases
they will be set exactly the same.
NOTE: Rotating the volume control fully
counter clockwise will yield no power
going to the speakers (off).
C. To change color:
1) Pull off knob.
2) Unscrew coverplate.
3) Unsnap inner cover.
4) Snap on new inner cover.
5) Screw on new coverplate.
6) Push on new knob.

Speaker Level / Impedance Matching
Volume Control
Formula for calculating impedance of parallel speakers:
(2 - 8 ohm speakers in parallel exhibit 4 ohms of impedance)
NOTE: Speakers wired in series exhibit purely additive
impedance (8+8 + 16).
IS-1507094 REV. O
1/x ohms + 1/x ohms = 1/y impedance
1/8 ohms + 1/8 ohms = 2/8 ohms or 1/ 4 ohms
