PHONO CARD ADJUSTMENTS
If the Phono Card option has been factory installed, so that Input 2 on the rear of the CONCERTO is dedicated for phono operation only, the following adjustments can be made to optimize the performance of a particular phono cartridge. These adjustments include both cartridge loading and overall phono amplifier gain.
STEP 1:
Unplug the CONCERTO power cable from the wall AC outlet.
STEP 2:
Place the unit upside-down on a soft, clean surface. Using a #2 Phillips screwdriver, remove the twelve screws that secure the bottom cover of the unit.
STEP 3:
Carefully remove the phono card from the back panel by easing it gently back and forth until it separates from the unit.
STEP 4:
Locate the LOAD and GAIN switches on the phono card. (See FIGURE 10) Adjust the Load Resistance and Gain settings on the plug-in Phono Card.
STEP 5:
Replace the bottom cover. Using a #2 Phillips screwdriver, reinstall the twelve screws that secure the bottom cover.
