ceived. It can be forced to stay on by
IQ software to assist with trouble-
shooting of an
IQ System.
3.21 AUX Output
A 3-pin male mini XLR connector is
provided to control auxiliary equip-
ment. When the AUX feature is turned
on, +15 VDC is provided across pin
1 (gnd) and pin 3 (+). A nominal cur-
rent of 10 mA is available. The
IQ
System is used to control the AUX
output.
3.22 Memory Backup
A memory backup feature is pro-
vided which can be disabled, if de-
sired. The factory default setting is
“enabled.” When enabled, it stores all
run-time parameters that can be con-
trolled by the IQ software into non-
volatile memory (EEPROM) at
approximately one second intervals.
When disabled, all run-time param-
eters are returned to the factory de-
faults whenever the unit loses power.
CAUTION: CAUTION: CAUTION: CAUTION: CAUTION: Be careful to turn on the
memory backup feature if the input
attenuators will be used to set critical
levels. If the memory backup feature
is turned off and the
IQ–P.I.P.–SMT
loses power, the attenuators will be
reset to 0 dB, resulting in the loudest
possible signal.
3.23 Reset
A recessed reset switch, accessible
from outside the
IQ–P.I.P.–SMT, en-
ables it to be restored to one of two
sets of default settings. A straight-
ened paper clip or similar small ob-
ject is required to press the reset
switch.
Press the reset switch for less than 2
seconds and all settings, except the
amplifier ID code or user scale fac-
tors, will be reset with “user default”
parameters and the DSPI will flash
once. This feature is only available if
“user default” settings have been
previously established. If none have,
pressing the reset switch for any
length of time will cause the unit to
be reset to the “factory default” set-
tings as described below.
Press the reset switch for more than
2 seconds and the same settings will
be reset with “factory default” param-
eters and the DSPI will flash twice.
After the unit has been reset to the
factory default settings, it will behave
like a standard
P.I.P.-FX until it is re-
programmed by an IQ System or it is
toggled to the “user default” settings.
3.24 User Default Settings
The parameters for all functions, ex-
cept the amplifier ID code or user
scale factors, can be saved as “user
default” parameters. Then, pressing
the reset switch for less than 2 sec-
onds will restore all settings to the
“user default” values. Please consult
the documentation of your IQ soft-
ware for instructions on setting the
“user default” values.
