IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems
being installed into a PIP2-
compatible amplifier, move
both jumper JP4 and JP5 on
the IQ circuit board to the
“OUT” position (Figures 2.1
and 4.8). Set both JP4 and
JP5 to the “IN” position for
all other amplifiers.

6. Remove the existing PIP Remove the existing PIP Remove the existing PIP Remove the existing PIP Remove the existing PIP or
cover panel from the ampli-
fier back panel (two
screws). For PIP2 amplifiers,
this may involve disconnect-
ing the PIP from a PIP2 input
adapter (Figure 4.6). If a
PIP2 input adapter is al-
ready present, do not re-
move the ribbon cables from
the adapter. Otherwise you
will have to reconnect them
in Step 9.
7. Set the amplifier input
sensitivity to 0.775 V. (See
the amplifier’s Reference
Manual.)

9. Install the IQ–P.I.P.-MEM
into the amplifier:
Standard PIP Amplifiers:
Align the edges of the IQ–
P.I.P.-MEM in the PIP card
rails and firmly push the unit
in until it is seated against
the mounting bracket (see
Figure 4.5).
PIP2 Amplifiers: Connect the
PIP2 input adapter to the two
input cables of the amplifier
(Figure 4.6). Notice that the
PIP2 input adapter should
be
positioned with the PIP edge
connector on top facing
away from the amplifier. The
