ning a radio console. iQ makes mix-minus easy by auto-
mating it. The operator never has to worry about sending
a source back to itself and getting feedback— it just can't
happen!
Several fixed and auto-switching mix-minus choices
are possible, and are configured for each source when
Source Profiles are defined by the engineer (see Chap-
ter 2 for details). Once this setup is done, no further
tweaking is needed; the operator simply uses the source.
A fader's status display tells operators when a particu-
lar source has a mix minus output, and even tells them
which audio mix is being backfed.
iQ will generate as many mix-minus outputs as there
are faders, each with its own automated mix minus feed.
If you have 16 faders, you can have 16 mix-minuses!
GPIO
Chapter 2 explained how sources can have associat-
ed GPIO (General Purpose Input/Output) control associ-
ated with them. External GPIO interfaces are connected
to iQ via the Livewire network (more details in Chapter
7) , so you can locate the actual machine connections ei-
ther physically close to source equipment or in a central
equipment room.
During installation, the engineer configures sources
to accept and provide logic commands by selecting vari-
ous options. For example, studio mics may be set up to
automatically mute the studio monitor speakers and il-
luminate an on-air warning light when turned on. The
same sources can be configured to accept GPIO logic
inputs from buttons, so that each studio guest can have
their own

Talk
Line sources can be configured to receive start and
stop commands from the iQ as well. Start/stop messages
can also be passed, via Ethernet, to a computer-based
playout system.
Software
The iQ operating system uses a high-performance
embedded Linux kernel to help ensure bulletproof, 24/7
operation. Software updates can be obtained from Axia
keys.

iQ Main Frame - Callouts and Operation
This section provides a "bird's-eye view" of the iQ,
with full descriptions of its controls and their functions.
Although an iQ console may have a fixed number of
faders, you are not limited to that number of sources.
Just like iQ's big brother, Element, you may assign any
source to any fader. Unlike Element, iQ's metering is
built-in.
The iQ Main Frame is laid out in a conventional
manner with the monitor and ancillary controls located
on the right side of the frame. Let's look at each of these
sections in detail.

2.
Channel ON Switch:
fader-normal mode the ON key turns the channel on
and the OFF key turns it off. The channel
functions also provide logic (start and stop puls-
Off
es, monitor muting, etc.) specific to the source type.
For example, if a control-room mic is assigned to a
fader, the CR monitors and Preview speakers will
mute when that fader is turned on and when CR mi-
crophone sources are Previewed. If a fader is hosting
a microphone source, pressing the
fader is already on mutes the channel, providing a
"cough" function, until the
3.
Each channel has a Soft Key. The
SOFT Key:
OLED display tells you what function the soft key
is currently controlling. The default action depends
upon the type of input assigned to that fader, which
is defined in the Source Profile. Current functions
of the key are Mute, Talkback and phone hold. This
key is also used to exit Channel Options edit mode.
