2 . increase the Master volume in one zone until you
achieve the desired maximum level.
4 . Dial in limiting (rotate counterclockwise) until you
begin to hear the level drop. Stop.
5 . Increase the front panel controls to full. The peak
level should only increase somewhat; if
necessary, dial in a little more limiting. Continue to
make small adjustments until you are satisfied
with the combination of maximum level and
limiting action.
6 . Repeat with the other zone.

power delivered to the load. Since the PowerLimit
circuit monitors output voltage, it will be of primary
benefit when used to protect 4-8 ohm loads from
excess power. (Speakers in 70V systems are tapped
for the appropriate wattage). To use the PowerLimit
control to protect 4-8 ohm speakers from excess
power:
1. For 8 ohm speakers:
a. Determine the manufacturer’s power
rating (eg 50 watts).
b. Divide this number by 150 to get the
percentage (eg, 50/150 = 33%).
c. Adjust the PowerLimit Control to this
value (eg, 33%).
2. For 4 ohm speakers:
a. Determine manufacturer‘s power rating
( eg, 50 watts)
b . Divide this number by two (eg, 50/2 =
25 watts).
c . Follow steps b. and c. above (eg,
25/150 = 16%, set PowerLimit).
