Ms Stereo Monitoring; Soundfield B-Format Surround Monitoring - Sound Devices 788T-SSD User Manual And Technical Information

tor mode has been selected with the Multi-Function Rotary Switch or with the Input Selector/Solo
Switch. If it is desired to access the Input Settings Window without soloing the input, disable the PFL
function in the Setup Menu option INPUT: PFL FUNCTION.
When a CL-8 is attached a user can quickly solo an input by pressing the A and B buttons from the
CL-8 Main View. See CL-8 for more details.
If the selected input is stereo linked, both of the inputs will be soloed in the headphone monitor.

MS Stereo Monitoring

The MS stereo mode decodes discrete Mid-Side stereo signals to a left/right stereo signal for moni-
toring purposes. This allows for a proper stereo signal to be monitored in the fi eld while discrete M
and S signals are recorded for later post production. For the MS decoder to operate properly, the Mid
signal is connected to either of the odd inputs (1, 3, 5, 7) and the Side signal is connected to the even
inputs (2, 4, 6, 8). The amount of stereo "spread" is fi xed at a 50/50 percentage from Mid to Side
signal.
If MS is selected for input linking, do not use MS stereo monitoring. This would result in two MS decod-
ers being inserted in the signal path. The resulting audio in the headphones would be the discrete M and
S signals!

SoundField B-Format Surround Monitoring

SoundField B-format is a four channel surround sound format generated by SoundField surround
microphones. The 788T can accept the four signals output from a SoundField microphone and record
each to its own track.
When recording four-channel B-format audio, the 788T headphone monitor can decode the B-format
signal into L/R stereo. The 788T constructs a stereo signal using the W, X, and Y signals of the B-
format. The Z-axis signal is not used. Similar to the 788T's MS stereo monitoring, the stereo width is
fi xed for headphone monitoring.
To record and monitor B-format signals, connect signals as follows:
SoundField 788T
W signal input 1, track L
X signal input 2, track R
Y signal input 3, track A
Z signal input 4, track B
SoundField fi les generated in other recorders or software applications can be copied to Compact-
Flash or the 788T internal drive and can be played back and monitored in stereo. Make certain that
channel assignments follow the order above for proper headphone decoding. If multiple monophon-
ic SoundField .WAV fi les are named using the "_W, _X, _Y, _Z" suffi xes, the 788T will recognize that
these are multiple monophonic B-format fi les and will play them back in the proper track order.
The 788T can play back monophonic or polyphonic B-format fi les.
There are two B-format monitoring selections, one for inputs and one for tracks. They are listed as
INPUT B-FMT STEREO and TRACK B-FMT STEREO. For most recording and playback applications
the track monitor selection is appropriate. If the user wants to hear the inputs at all times, the input
monitor selection is appropriate.
