Adjusting Potentiometers
The VEA6800+ module has two separate, adjustable potentiometers
(“pots”) for gain and EQ mode adjustment. Figure 2-9 on page 22
shows the location of these pots.
A multi-turn pot allows you to adjust gain for a range of –3 dB to +3
dB. See Figure 2-11.
• To increase the gain, turn the pot clockwise.
• To decrease the gain, turn the pot counterclockwise.
A second multi-turn EQ pot allows you to adjust cable equalization. See
Figure 2-11.
• To increase equalization, turn the pot clockwise.
• To decrease equalization, turn the pot counterclockwise.

Adjustment
A single-turn pot allows fine adjustment of the CMR. A separate
single-turn pot controls response; an additional variable capacitor
controls EQ response. The adjustments have been set in the
manufacturing facility; readjusting is not recommended without
precision test equipment.
