Soundfield DSF-3 Digital Surround Processor

The DSF-3 is a digital surround processor that decodes the digital SoundField B-Format signals generated by the DSF-1 and DSF-2 system simultaneously into digital 5.1 surround sound and stereo at any incoming sample rate. Four 5-segment LED displays on the left side of the front panel act as input level meters, and each 5.1 channel's output level control has separate green 'signal present' and red Clip LEDs for further peace of mind. Controls on the front panel of the DSF-3 allow a degree of freedom to alter the audio being decoded that only a SoundField system can offer: there are separate output level controls for each of the six channels in the 5.1 signal (Left, Center, Right, Left Surround, Right Surround and the LFE channel), and further rotary switches and buttons allow users to alter the pickup pattern and orientation of the microphone without physically handling it. The front and rear width of the 5.1 pickup pattern may be continuously altered with two more rotary controls, and a Focus control allows the user to vary the localisation characteristics of the soundfield image. The entire 5.1 soundfield can even be rotated through 360 degrees by means of a rotary encoder with a live front-panel readout in degrees. The last control also affects the independent stereo soundfield, for which separate front-panel controls are offered to adjust the stereo polar patterns and perceived stereo width.

Separate rear-panel outputs are provided for broadcasters for each of the five main channels and the LFE channel in AES3 format on 75 Ohm BNC connectors. The B-Format inputs to the decoder are on the same connectors. An additional rear-panel BNC provides the separate Left/Right Stereo output, which can also be used for Mid & Side signals. The six surround channels and the independent stereo channels are simultaneously sent out via a single digital ADAT lightpipe connector for those users with compatible equipment. Word clock inputs and outputs, and a USB port for software control (see DSF-3 Remote App below) comple the rear panel.
