IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems
J. Amplifier Output Pad
Jumpers (JP4, JP5)
These jumpers enable the circuitry
that pads the output signal feeding
the IQ–P.I.P.-MEM so it can be
properly scaled. Factory default
setting for these jumpers is the
“OUT” position as marked on the
digital circuit board. Switch to the
“IN” position whenever the unit is
installed into a PIP-style amplifier.
K. PIP2 SIP Sockets (RN1,
RN2)
These eight-pin SIP (single in-line
package) resistors are provided
for full PIP2 compatibility. IQ–
P.I.P.-MEM-PIP2 modules (re-
quired for PIP2-compatible ampli-
fiers) should come with the SIP net-
works already installed. The SIP
networks are not required and
should be absent on standard IQ–
P.I.P.-MEM modules.
L. IQ Circuit Board (Top)
The top circuit board contains the
IQ communication circuitry, includ-
ing the IQ address switch (SW1),
amplifier output pad jumpers (JP4,
JP5), PIP2 SIP resistors (RN1, RN2)
and the PIP edge connector.
M. Audio Circuit Board
(Bottom)
The bottom circuit board contains
the audio analog circuitry, includ-
ing the input switches (S1, S2).
N. IQ Address Switch (SW1)
An 8-section DIP switch is used to
set the IQ address of the unit (see
Section 4.1). This switch is located
on the top circuit board. Each IQ
component on a Crown Bus is
given a unique IQ address so it can
be independently controlled and
monitored. Two or more IQ compo-
nents of the same type should
NEVER have the same address on
the same Crown Bus loop.
