to set the IQ address of the
IQ–P.I.P.–SMT. No two IQ
components of the same type
which are connected to the
same Crown Bus can have
the same address. Suppose,
for example, the
IQ System
has two Crown Bus loops and
this
IQ–P.I.P.–SMT is installed
into loop 1 and given address
77. No other
IQ–P.I.P.–SMT
can have the same address
in loop 1. However, an
IQ–
P.I.P.–SMT 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.–SMT
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 reserved
for special use. An address
of “0” (zero) should never be
used except to put the
IQ–
P.I.P.–SMT into a stand-alone
mode where it is invisible to
the
IQ System and acts as a
“dumb” balanced audio in-
put.
Switch SW1 is located on the
right side on the underside of
the top circuit board (Figure
4.1). It has eight segments
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” posi-
tion 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 ad-
dress 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.
