WHAT IS IT? SoundField introduce its next level of microphone technology with the SoundField SP451 Surround Sound Processor. The SP451 expands the possibilities within the SoundField family to offer in just 3U of rack space a complete 5.1 surround, stereo, mid/side and mono microphone package. The addition of the SP451 makes the SoundField Microphone the lowest cost and most flexible multi-channel microphone system available in the world. WHAT MAKES IT DIFFERENT? The SoundField SP451 is designed to work with the B-Format outputs from a MKV or ST250 SoundField Microphone System. HOW DOES IT WORK? From the B-Format outputs, either in real time or from tape, the SP451 delivers a high quality, full band, discrete Left/Centre/Right (L/C/R), Surround Left/Surround Right (SL/SR) ‘mic’ output plus a subwoofer (<80Hz) ‘mic’ output. Each of these six ‘mic’ outputs has its own level control and output level meter, plus the five mic array has individually definable mic patterns. The mic patterns are determined by an internally installed SoundField MAP (mic array pattern) card. One MAP card is included as standard with the SP451 which is a cardioid L/C/R/SL/SR card. An optional second and third card can be added to the SP451 set up in almost any 5 mic array configuration imaginable. Any of the three cards can be selected from the front panel to apply a different mic array pattern to real-time B-Format or B-Format recordings.  Each of the 5 microphone locations is based around commonly accepted surround mic positions
of Left (at –45 degrees), Centre (0 degrees), Right (+45 degrees), Surround, Surround Left (-135
degrees), Right (+135 degrees) with a Sub out (summed from all outputs below 80Hz). Add to
this impressive list of operational modes the option to change the front Left/Right microphones
and the rear Left/Right microphone positions by +/-45 degrees from their ‘centre’ position, and
the SP451’s flexibility becomes apparent.SP451 Surround Outputs  The SP451 surround audio outputs are mixed and handled as ordinary individual microphone outputs, but already at line level. No further special SoundField processing is necessary after the audio leaves the SP451. |
