BALANCE
The balance knob controls the balance between the main stereo output and the stereo Cue signal when
selected.
Note: The split switch de-activates the balance control.
With the balance control anywhere between Cue and L/R you always have control over the main output
signal even when a Cue switch is activated.
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). The balance control has no influence on this configuration anymore.
PHONES
The phones output (located on the front panel) has an automatic input selector.
Normally the left/right output is heard until a Cue switch is activated anywhere in the console that
immediately takes over the left/right signal. The led bar switches accordingly with this action.
We advise you to use headphones with an input impedance not lower than 400 Ohm to avoid distortion.
An 8 Ohm headphone will produce lots of distortion when cranking up the level due to its low impedance
load. It is a load equivalent to the load that loudspeakers normally present to power amps and as you know
the AIRMATE-USB is no power-amp, sorry.
MASTER FADERS
The AIRMATE-USB master faders are 60mm models controlling both left and right signals individually to
compensate for imbalances in the audio signals.
SELF-OP
This switch mutes the monitor output (your control room monitor) as soon as a microphone input is opened.
At the same time a relay is activated which is connected to the Red Light output connector.
CLEANFEED OUTPUT
The Clean feed output sums all signals coming from the input modules (except for those inputs where
jumper J7 is not activated). 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 by way of the Cue switch.
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 by
the same signal as the phones output is.
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 extensive 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 upon settings
of the master controls of the Clean feed and
Announcer outputs. It is however subjected to
the master level of the master Aux output
control. The Talkback switch has a momentary
action to avoid being unwillingly in the talkback
mode.
MASTER CONNECTORS
The master connector panel houses 12 Cinch
connectors 2 jacks and 2 male XLR connectors
where all interfacing takes place. Furthermore
the mains connector with integrated fuse holder
is located in this section.
A ground terminal completes the back panel
connector section.
