Photos of the CFX101LA were used in
these instructions. The procedure for
installing these amplifiers into CFX121
and CFX151 loudspeakers is nearly the
same. The difference is that they have a
Crossover Network mounted in the bottom
of the cabinet instead of a rear mounted
Balance Control.
Step 1
Use a Phillips screwdriver to remove the
screws holding the connector plate in
place and carefully remove the connector
plate. Save the screws. You’ll need them
to install the amplifier.
Step 2.
Disconnect the 2-pin white connector from
the connector plate by squeezing the sides
of the connector and pulling. Set the con-
nector plate aside.
Step 3
If you are installing a PF2-500R bi-ampli-
fier, you will need to bypass the Balance
Control and connect the amplifier’s outputs
directly to the transducers. Remove the
screws holding the Balance Control plate
in place and set them aside. You’ll need
them to reinstall the Balance Control plate.
If you are installing a PF1-500 or PF1-
500R amplifier, you do not need to remove
the Balance Control so you can skip this
step and proceed directly to Step 7.
Step 4.
Remove the Balance Control plate from the
cabinet.
Step 5.
Disconnect the white 4-pin connector from
the Balance Control (Crossover Network)
by squeezing the sides of the connector and
pulling.
Step 6.
If you are installing a PF2-500R bi-amplifier,
connect the white 4-pin connector to the
amplifier.
Note that this bypasses the Balance Control
(Crossover Network) and it no longer will have
any effect on the loudspeaker’s performance.
Step 7.
If you are installing a PF1-500 or PF1-500R
amplifier, connect the white 2-pin connector to
the amplifier.
Note that this keeps the Balance Control
(Crossover Network) in the audio path.
Step 8.
Carefully slide the amplifier into the cabinet
and use the Phillips head screws to secure it
in place.
Step 9.
If you are installing a PF2-500R bi-amp-lifier
into a CFX101LA, reinstall the Balance Con-
trol plate and secure it into place.
