Channels
Max Air can have up to 200 channels. Mono channels may be grouped as stereo or any for-
mat up to 7.1, which means that one fader may use one to eight logical channels.
Strips
Each fully loaded CM416 16-channel Module contains 16 physical faders or strips. Each
fader can control two inputs using a Swap button that switches between the Swap and Main
channels.
Layouts
Channels are assigned to strips by using Layouts. Numerous Layouts can be easily stored
and recalled to remap the console surface. To understand Layouts, consider the following
examples:
•
A console fitted with one CM416 has 16 physical faders that can control up to
32 channels (Swap and Main per strip). One Layout can assign 32 stereo inputs
to the faders for a total of 64 logical channels.
•
The first 32-channels can be assigned and left connected to the mix buses while
a second Layout is recalled. If none of the channels between the Layouts are the
same, there are now 64 logical channels feeding the mix buses at the same time,
although they cannot be controlled simultaneously from the console surface.
Layouts may also be used to place the inputs most often used on the top fader layer, or in-
puts that should be grouped together (i.e., microphones or VTRs).

Digital Signal Processing

The DF66 SuperCore is a rack-mounted unit that performs all Max Air audio processing:
dynamics and EQ, mix buses, record buses, aux sends, and monitor buses. The DF66 DSP
can be allocated, using factory-supplied Mixer Model files, to provide different numbers
of buses and channels for each studio. The number of DF66 DSP cards required in a sys-
tem depends on the number of logical channels desired: a mono input uses one logical
channel, a stereo input uses two, and a 7.1 input uses eight.

Analog and Digital I/O

All audio signals are converted to and from the MADI format through analog and digital
converters, and HD/SD embedders/de-embedders. Up to twenty-four input and twenty-
four output MADI devices are connected to the CO600 Changeover System, which con-
nects to the DF66 cores.
Analog I/O
All analog signals are converted between analog and MADI formats via the AM713 Ana-
log to MADI Converter, the MA703 MADI to Analog Converter, Modular I/O cards AD920
4ch Analog Line Input, DA921 4ch Analog Line Output, and AD924 4ch Mic Input. The
