USB2 can carry up to 480Mbits/s of data and for recording 64 tracks of 48kHz/24bit
the maximum data rate we need is around 80MBits/s so there’s normally plenty of
headroom. JoeCo has already tested numerous USB2 drives from Western Digital,
Glyph, Seagate, Verbatim, Samsung, Buffalo, Hitachi, Toshiba, G-tech and others and
found them to work well. We chose the FAT32 filing system because it is compatible
with all major Operating Systems and it’s also the format chosen for the AES31 digital
interchange standard.
However, bus-powered drives (such as the Western Digital Passport series) typically
draw more current during spin up than the USB2 specification allows (limited to
500mA) and can therefore not be used without providing a separate power supply.
Standard Flash RAM drives (aka Pen Drives) are not fast enough to take the full USB2
data rates that the BBR requires, but the fastest ones normally work ok. Larger
thumb drives (64GB and larger) are typically much faster and usually work well. Ask
the shop if you can try the drive with the BBR before you buy it.
You must make sure that the drive you are using is fast enough and not too
fragmented before you use it with the BlackBox Recorder. If in doubt, reformat the
drive and make a test recording of an hour or so to be sure. Then reformat the drive
again before recording the performance. Drives are very cheap nowadays so we
advise keeping a few spares around just in case.
Connecting a disk drive
Plug the disk drive into the USB2 socket on the back of the BlackBox unit and then
power up the drive. The drive will be scanned, logged and ready to use in a matter of
seconds. If it takes more than 20 seconds to log the drive or the BlackBox reports
“WRONG DISK FORMAT”, check that the disk is formatted correctly. The BlackBox can
be used to reformat the drive to FAT32 (see page 28).
Power connection
The BlackBox Recorder is supplied with its own power supply which plugs into the dc
inlet at the rear right of the unit (or left if you’re looking at the rear as you read this).
The power connector is a 4pin mini XLR connector, wired: pin 2 = 0V, pin 4 = 12V.
Although the unit can accept a suitable dc input between 7.5V and 16V it should
always be used with the power supply provided.
