See illustration for direction of arrows for Nominal Setting. Bottom pot should always be maximum CW. IRS amplifier output can be "trimmed" in relation to each other by powering system up with amp cover removed, attaching DMM to main amp terminals and comparing output voltage, driving with 50Hz signal to achieve approx. 5.0 volts at main amp terminals. If amp voltages are not equal on both towers, carefully adjust (raise/lower) Center ACCELERATION/FEEDBACK pot on one unit until they are. Connect an AC voltmeter to these test points to assure high speed of cooling fan is working. With AC meter attached to these points with COLD system, voltage should be less than 100v. Drive system at 20-30Hz either into woofer tower
