SPLIT
When the split function is activated the following listening situation is created. The left side of the phones output
gives the summed Cue signal and the right output gives the summed left/right signal (pre fader). With the SPLIT
switch activated, the balance control has no inuence on the conguration any longer.
PHONES
The phones output (located on the front panel) automatically
switches between main mix outs and QUE from any input modules
or on the Master section. Normally the left/right output is heard
until a Cue switch is activated from anywhere in the console.
Pressing a CUE switch, you will hear the associated signal rather
than the left/right signal in the PHONES. The led bar switches ac-
cordingly with this action.
We advise you to use headphones with an input impedance NO
LOWER THAN 400 Ohms to avoid mismatch or distortion.
An 8 Ohm set of headphones will produce distortion when crank-
ing up the level of the Airmate-USB due to the impedance load
is too low. If you must use 8 ohm phones, a small power amp
should be used to power the phones. It is a load equivalent to
the load that loudspeakers normally present to power amps. The
AIRMATE-USB has no power-amp.
MASTER FADERS
The AIRMATE-USB master faders are 60mm models controlling
both left and right signals individually to compensate for imbal-
ances in the left & right audio signals.
SELF-OP
This switch mutes the monitor output (control room monitor
speakers) as soon as a microphone input is opened. At the same
time a relay is activated which is connected to the Red Light out-
put connector.
CLEANFEED OUTPUT
The Clean feed output sums all signals coming from the input
modules (except for those inputs where jumper J7 is not activat-
ed). Clean feed signals are equivalent to Aux send signals, but are
always post fader. By jumpering only those channels that are not
returning Telephone Hybrid signals you avoid feedback and have a
perfect set-up for talk shows. The Clean feed output is only used
when an external Hybrid is used.
CLEANFEED
All outgoing signals from the Clean feed output can be monitored
via the Cue system.
ANNOUNCER OUTPUT
In the up position of the “follow phones” switch, the input of the
announcer is fed by the main left/right signal pre master fader. In
the depressed mode of the “follow phones” switch, the Announcer
output is fed via the same signal as the phones output.
FOLLOW PHONES
This switch is the input selector of the announcer output, see above description.
TALK BACK
The Talkback circuit has a built in electret microphone with routing to most of the outputs.
By selecting one or more of the routing switches, you can communicate to the outputs.
The Talkback level is independent of settings of the master controls, the Clean feed, and Announcer outputs. It is
however put through the master level of the master Aux output control. The Talkback switch has a momentary ac-
tion to avoid being in the talkback mode when not wanted.
