6. To remove an input-to-track combination assignment, navigate that combination and press the
UNASSIGN soft key or Rotary Switch.
7. Exit and complete the assignment by pressing the check mark soft key.
The input routing menu will always exit to the main screen whether entered from the input key or the
menu selection.
Selective Input Muting
When the INPUT key is pressed, individual input muting is available. This feature can be used to
quickly mute microphones while maintaining their respective track assignments.

Mono- and polyphonic files behave differently when selective muting is applied When monophonic
files are selected, files from tracks A, B, C, and D are named with the suffix “_1, _2, _3, and _4” re-
spectively. If, for instance, track B is muted but tracks A, C, and D are still selected, the resulting files
will be named “_1, _3, and _4” and track B will not be recorded, saving storage space.
When polyphonic files are selected a four track file will be generated with track B being a blank
track. Blank tracks in polyphonic files take up the same amount of storage space as tracks that are
assigned.
Sampling Rate and Bit Depth
When recording the 744T generates uncompressed PCM audio WAV files in the Broadcast Wave File
format at the user-selected sampling rate and bit depth. The 744T LCD calculates available recording
time based on the sampling rate, bit depth, number of tracks set for recording and the selected stor-
age media available capacity. See the Calculating Recording Time later in this guide to estimate record
time.
Sampling Rate
When a sampling rate is selected for recording, all tracks are recorded at the selected sampling
rate. Sampling rates are selected among common rates from 32 kHz to 192 kHz. Additionally, non-
standard sampling rates can be applied when the 744T is word clocked from an external source
(clock sources between 32 kHz and 192 kHz). When recording off-speed sampling rates files will be
stamped with the rate closest to an internally generated frequency.
