sert the assembly into the 

P.I.P.

opening in the back of the ampli-
fier.

4. Tighten the two 

P.I.P. mounting

thumbscrews.

5. Connect input and output wiring.

6. Plug in the amplifier and turn it on.

Adjust its level controls to a de-
sired setting. (In Dual mode, the
level controls can now be used to
balance the low and high fre-
quencies.)

Do not tamper with the circuitry.
Circuit changes made by unautho-
rized personnel, or unauthorized
circuit modifications are not al-
lowed.

driving other components in your
sound system.

Figure 3.20 shows how to wire a
balanced and unbalanced source
or daisy-chain output to the barrier
block connectors.

Important:

 If the amplifier is used

in either Bridged-Mono or Parallel-
Mono mode, you must turn the Ch.
2 amplifier level control off (fully
counterclockwise). The input and
level control of Ch. 2 are not de-
feated in mono mode so any signal
applied to Ch. 2 will beat against
the signal in Ch. 1.

Refer to the amplifier

Bridged-Mono or Parallel-Mono
modes of operation.
