IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems

the same Crown Bus Loop
can have the same address.
Suppose, for example, the
IQ System has two Crown
Bus loops and this IQ–P.I.P.-
MEM is installed into loop 1
and given address 77. No
other IQ–P.I.P.-MEM can
have the same address in
loop 1. However, an IQ–
P.I.P.-MEM in loop 2 can
have the same address.

Different IQ components in
the same Crown Bus loop
can have the same address.
For example, both an SMX-6
mixer and an IQ–P.I.P.-MEM
can use address 77 in the
same loop.

A valid IQ address is any
number from 1 to 250. Do
not use a number higher
than 250 since they are re-
served for special use. An
address of “0” (zero) should
never be used except to put
the IQ–P.I.P.-MEM into a
stand-alone mode where it is
invisible to the IQ System
and acts as a “dumb” bal-
anced audio input.

Switch SW1 is located on the
right side on the underside
of the top circuit board (Fig-
ure 4.1). It has eight seg-
ments because it actually
contains eight tiny switches
inside. There is an arrow
printed on the switch along
its left side that points to the
“ON” position and the
switches are numbered
along the bottom (Figure
4.2).

Each of the eight switches in
SW1 has a value which
doubles as the switch num-
ber increases. For example
switch 1 has a value of 1;
switch 2 has a value of 2;
switch 3 has a value of 4;
switch 4 has a value of 8 and
so on.

The address is determined
by adding the values of all
switches which are turned
on. In Figure 4.2 switches 1,
3, 4 and 7 are on. Simply add
the values to find the ad-
dress: 1+4+8+64=77.

A convenient series of IQ
address tables are included
in Section 7. The tables show
the switch settings for all 250
addresses.

2. Set the input switches S1

and S2. Each input can be
configured for either line-
level or microphone-level
signals with an 8-segment
DIP switch. Phantom power
is also available. Switches
S1 and S2 (see Figure 4.3)
are located on the left side
of the lower circuit board.
The table in Figure 4.4 shows
how to set each switch.
