SoundField SP451

Welcome to the next level of microphone technology with the SoundField SP451 Surround Sound Processor. The SP451 expands the possibilities within the SoundField family to offer a complete 5.1 surround, stereo, mid/side and mono microphone package. The addition of the SP451 makes SoundField Microphones the lowest cost and most flexible multi-channel microphone systems available in the world. It is designed to work with the B-Format outputs from a MKV, ST250 and SPS422B SoundField Microphone Systems.

Features:

• B-Format input metering with level control
• Front Width adjusts the angle of Front Left/Rightmics by ±45 degrees
• Rear Width adjusts the angle of Rear Left/Right micsby ±45 degrees
• Rear Focus enables adjustment of the rear pair microphone polarpatterns

From the SP451 Input Section 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 SP451 can accommodate up to three MAP cards, each of which generates a different surround microphone array with pre-defined combinations of polar patterns.
