BRIDGED MONO OPERATION
The
Model 2202IQ
is built with the right channel inverted. This allows the
amplifier to be used in a bridged mono configuration.
These amplifiers are capable of driving 2-ohm mono loads (**4
ohm speaker
impedance**).
To use these amplifiers in that configuration, the internal taps
must
be changed. Removing the faceplate and changing the spade connectors
from the
‘4’
setting to the
‘2’
setting accomplish this.
The wiring for the bridged mono mode is as follows:
With the connector end of the amplifier facing you, top side up, the speaker
terminal block is arranged:
LEFT (-); LEFT (+); RIGHT (-); RIGHT (+).
The mono
mode uses the
LEFT (+)
and
RIGHT (-)
connections. An electronic crossover,
such as the
XO3
, should be used to limit the frequency range to the input of the
amplifier for best results.
TWO-OHM CAPABILITY
Unplug the two jumper wires near the four large filter capacitors from the lugs
marked 4 ohm and press them firmly back onto lugs marked 2 ohm. This will
allow the amplifier to operate into a 2-ohm load on each channel, or a 4-ohm load
when used in bridged mono mode (**se
e statement above**
). The lugs are
marked
“2”
for 2-ohm stereo or 4 ohm bridged, and marked
“4”
for 4-ohm stereo
and 8 ohm bridged.
SPEAKER OUTPUT - MODEL 2202IQ
The output current capability of the
2202IQ
exceeds the rating of standard
speaker plugs. To ensure a good connection with this much power, a terminal
strip is used. The speaker cable can be brought directly to the amplifier and
connected as: LEFT (-); LEFT (+); RIGHT (-); RIGHT (+).
OPERATION / ADJUSTMENT
For any system to operate at minimum distortion with minimum noise and still
reach full power output, the equipment should be aligned to operate at the same
point on the distortion curve at the same time. In a basic system, using a single
amplifier, set the amp sensitivity adjustment to minimum, turn the deck up until it
just starts to distort, then back down slightly. This is the point where the output of
the deck is cleanest. Now, bring the sensitivity control of the amp up until it just
starts to distort, and back it down slightly. This will allow the amp and the deck to
reach maximum usable output at the same time.
