Just as with SoundField’s other microphone products, the ST350 system produces a four channel signal in the company’s proprietary B-Format. The ST350 processor has built-in decoding to convert the B-Format signal to a Stereo or Stereo M/S output, which can be routed to the dual rear-panel XLR connectors. Alternatively, the B Format signal may be output via the rear-panel multi-pin Lemo connector. Other decoders in the SoundField range, such as the hardware SP451 or the Surround Zone software (now compatible with Pro Tools, Nuendo and SADiE DAW systems) can then be used to decode the signal to create a variety of surround-sound formats — and all from the one multi capsule ST350 mic.
Also built into the ST350 control unit are various B-Format processing options, unique to SoundField microphones, that allow users to continuously vary the apparent orientation and stereo pickup pattern of the microphone, but without touching the mic itself. An overall Gain control, stereo headphone jack, high-pass wind-noise reduction filter, and five-segment LED metering are also built in for recording convenience.
The ST350 is shipping now, and can be seen on SoundField’s stand at the AES show. For more information, come to Booth number 1313, or check out www.soundfield.com.
