Recording B-Format
Sound Devices
744T is a great companion to a SoundField ST350 microphone. The outputs from the ST350 preamplifier/control unit can interface directly to the line-level inputs on the
744T. The W, X, Y, and Z signals from the SoundField mic are connected to inputs 1, 2, 3, and 4, respectively of the
744T.
Monitoring B-Format
Because the B-format signals recorded by the
744T need to be decoded to some other format to be meaningful, the
744T has a B-format monitoring mode. B-format monitoring is selected from the headphone output Setup Menu option. When listening to the SoundField microphone, the
744T’s B-format monitor builds a stereo mix using the W, X, and Y signals. For more control in monitoring the SoundField, the ST350 controller includes a more flexible headphone monitoring system.
While customers with earlier ST250 SoundField microphones can use the
744T for recording, the ST350 preamplifier outputs are a better match for the gain structure of the
744T.
So just let me know when you are going to sell me your 722 so I can raise funds.
