RECORDING B-FORMAT FOR SURROUND POST-PRODUCTION
The ST450 shares many of the features of the other SoundField systems, but is unique in
that it can record full surround without mains power. The ST450 will run from any DC
source between 10V and 18V capable of providing 7W. For example, a 14.4V, 2.4Ah
battery will provide approximately 3 hours of operation.
The portable recorders then output the B-Format signals at line level which are then
decoded into full surround by either the Surround Zone software or hardware DSF-3 /
SP451 processors.
The advantage of recording an acoustic event in B-Format is that it can be decoded into
any current or future surround format and is therefore ideal for ‘surround archiving’.
