Chapter 2 explained how sources can have associ-
ated GPIO (General Purpose Input/Output) control as-
sociated with them. External GPIO interfaces are con-
nected to QOR via the Livewire network (more details
in Chapter 7 ) , so you can locate the actual machine
connections either 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
On
,
Off
,
Talk
, and
Mute
keys.
Line sources can be configured to receive start and
stop commands from the QOR as well. Start/stop mes-
sages can also be passed, via Ethernet, to a computer-
based playout system.
Software
The QOR operating system uses a high-performance
embedded Linux kernel to help ensure bulletproof, 24/7
operation. Software updates can be obtained from Axia
via the Internet and applied by the station engineer. Axia
Support recommends performing backups or making
printouts of Show Profiles and other configuration data
before applying new software updates.
Callouts and Operation
This section provides a “bird’s-eye view” of the RAQ
and the DESQ, with full descriptions of controls and
their functions.
Although consoles have a fixed number of channels,
you are not limited to that number of sources. The RAQ
and DESQ control surfaces are 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.
1.
Channel ON Switch:
The ON key toggles the
channel between the ON and OFF states. The chan-
nel ON and OFF functions also provide logic (start
and stop pulses, 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.
2.
SOFT Key:
Each channel has a Soft Key. The
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.
3.
PREVIEW Key:
allows the operator to listen
to sources before they air. RAQ/DESQ
Preview
bus
allows auditioning in full stereo. Individual source
profiles can change Preview to Solo (post-fader) op-
eration.
The
Preview
key acts like a latching switch.
Momentarily pressing any channel’s
Preview
key
assigns that channel to the Preview bus; pressing it
again removes the channel from Preview. To enable
an operator to quickly listen to various sources, the
Preview function can be interlocked: pressing
Pre-
view
on any channel will remove any other channel
from Preview mode.
If you want to preview multiple channels, pressing
and holding any
Preview
key temporarily disables
the interlock; other sources can be added to the Pre-
view mix by pressing them. Conversely, channels
can be removed from a multiple Preview selection by
pressing and holding any lit
Preview
key and dese-
lecting the individual channels you wish to remove
from Preview.
