ISO Routing
The ISO routing menu is where the ISO tracks (tracks 9 thru 24) are assigned an input. Any of the 16 analog inputs or
24 digital inputs can be assigned to the any one of the ISO tracks.
Assigning an input to a ISO track
Setting the ISO track as pre or post fader
Each ISO track can be routed as either pre or post fader. Tapping on the FADER key
on the lower left will toggle between “Pre” and “Post” fade. This sets the state of
how the input will be routed. So for example if the “Pre” is displayed any input
selected will be routed pre fader. If the “Post” is displayed any input selected will be
routed post fader.
Routing an input to the ISO track
Select the desired ISO track (9 thru 24) to be assigned by tapping on the track
number. This will open the ISO source menu for that track. From the ISO source
menu tap on the desired input to be routed to that track.
To remove an ISO routing select the track number which will open the ISO source
menu, then tap on the input to toggle it off.
An analog input routed post fader will be displayed light green and an analog input
routed pre fader will be displayed dark green.
A digital input routed post fader will be displayed light blue and a digital input routed
pre fader will be displayed dark blue.
Enabling ISO attenuation
The NeverClip™ inputs allow large signals to travel through the digital mixing
engine using 32 bit floating point numbers. Once these large signals are
recorded into a 24-bit WAV (or MARF) file, the advantage of floating point
math is lost and these signals can clip if not using a card limiter.
ISO Attenuation allows the ISO record tracks to be attenuated by a user selectable
amount of 6, 12, 18 or 24dB. This allows audio to be recorded without clipping
even if its dynamic range would normally be too large. This gain reduction amount
is stored in the metadata of the WAV file so post production can easily restore the
amplitude of the ISO tracks when necessary. To enable ISO attenuation tap on the
desired attenuation amount from the ISO attenuation matrix. Please note that the
ISO attenuation is a global setting - meaning the same amount of attenuation will
be applied to all tracks.
