whether the amplifier output is
distorted simply because of an
excessive input level. The range
is from +16 dBu to –40 dBu.
Report Via Aux: Enables or
disables a feature which causes
the AUX port output to stay on
during normal operation and
turn off whenever a fault
condition exists (see Sections
3.21 and 4.8).
3.17 Auto Standby
The Auto Standby feature automati-
cally turns off the high-voltage sup-
plies of the amplifier when no audio
signal is detected at the input for a
predetermined period of time. The
channels are controlled indepen-
dently. Using it, many
IQ Systems
can pay for themselves in just a few
years due to reduced energy costs.
There are four parameters which con-
trol this feature:
Auto Standby: Turns this
function on/off.
Standby Level: Sets the level, in
dB, below which an amplifier
channel’s high voltage supply
will be turned off. The range is
from +16 dBu to –40 dBu.
Standby Time: Sets the time, in
minutes, that the input signal
must remain below the Standby
Level before the channel’s high-
voltage supply is turned off. The
range is from 0 to 255 minutes.
A setting of 0 (zero) yields a
turn-off delay of approximately 2
seconds to facilitate setup of the
function.
Use Turn-On Delay: Enables or
disables the IQ address turn-on
delay. This is a delay that
prevents all the amplifiers from
turning on at the same instant
and tripping power breakers
when an “all amps on”
command is issued by the
IQ
System. The turn-on delay is
calculated by: 10 msec x IQ
address value. It may be
desirable to disable this turn-on
delay when using the Auto
Standby feature so that the first
syllable of speech is not missed
when a voice page suddenly
causes the Auto Standby
function to turn a high-voltage
supply back on.
3.18 Auto
An Auto function is available to pro-
vide consistency with other IQ com-
ponents in the
IQ System. It is
controlled by the IQ System and it
serves as a toggle to quickly enable
or disable many of the functions in a
SmartAmp IQ–P.I.P.–SMT. The func-
tions that are enabled/disabled by
the Auto control are: smooth/output
signal limiter, auto standby and all er-
ror reporting functions (prolonged
IOC warning, excessive ODEP warn-
ing and fault warning). Please refer to
the documentation for your IQ soft-
ware for more information about Auto.
3.19 Crown Bus “Drop Out”
Relays
“Drop out” relays are provided on the
Crown Bus ports to maintain the con-
tinuity of the IQ communication loop
even if the
IQ–P.I.P.–SMT loses
power.
3.20 DSPI
A Data Signal Presence Indicator
(DSPI) is provided on the front panel.
It flashes whenever commands ad-
dressed to the
IQ–P.I.P.–SMT are re-
