2.1.3. Limiters
A limiter can be inserted into each channel, after the channel fader. This is a fast
limiter with a dynamic range wide enough to stand the 40 dB overhead of the input
stage.
The activation of the limiter is shown by an LED.
As long as the signal level stays below the limiter threshold, little effect is seen on
the signal. When the limiter is triggered, its output stays 3 dB below the A/D
converter clipping level for up to 40 dB input overdrive.
It can thus be seen as a “safety” limiter, that may be left active all the time!
The limiters on channels 1 and 2 provide two operating modes (selectable via the
menu):
x “Independent”, wherein each channel operates independently from the
other; this is suitable when the channels are two separate mono signals.
The limiter on channel 3 only works in this mode.
x “Linked”, which is the required mode for applying simultaneous
and identical gain reduction to both channels in « stereo » and M/S
modes, in order to preserve the coherence of the stereo image.
2.2. “EXT I/O” socket, radio receivers
The “EXT I/O” socket is available for the connection of an optional extension box.
This device can be used to interface MIXY with radio transmitters and/or receivers;
it can also house a removable battery pack and provide the mixer with additional
power.
When the extension device is plugged into the “EXT I/O” socket, the mixer can use,
for channels 2 and/or 3, inputs from the EXT I/O socket instead of XLR inputs 2
and 3.
The extension device feeds these inputs with two balanced signals. For safety, no
microphone powering is inserted into these inputs on the EXT I/O socket.
A specific sub-menu enables the switching of channels 2 and/or 3 from the XLRs to
the extension box.
The gain is adjustable in a 50 dB range for each of the two channels, which allows
to set a suitable level for the link from the radio receivers to the mixer channels.
