SURROUND POST-PRODUCTION: PART TWO
THE SOUNDFIELD SP451 SURROUND PROCESSOR
B-Format playback from Portable Recorder
In this configuration the ST450/SP451 combination will deliver six discrete channels of
5.1 surround sound.
The SP451 offers a rugged 1U rackmount hardware alternative to the Surround Zone
software. It is favoured by those wishing to bypass DAW’s and commit up to eight tracks
of surround sound directly to digital recorders ‘live’ as the performance takes place. It
can also be used ‘stand alone’ in post-production where from pre-recorded B-Format
material it will output a 5.1 surround mix and stereo mix simultaneously. It generates up
to three surround mic arrays with differing polar pattern combinations for instant
comparison. Front panel controls include individual 5.1 channel levels and metering with
variable Front Width, Rear Width and Rear Pattern for each mic array. The SP451 has B-
Format inputs (W, X, Y & Z) and up to eight surround outputs. Input/outputs are
balanced XLR at line level.
