USBPre- General Description
Sound Devices USBPre 1.5 is a complete, portable hardware interface for
computer-based digital recording. Designed for USB-equipped Macintosh® OS 9,
OS X, and Windows (98SE®, ME, 2000®, XP) computers, USBPre quickly and easily
interfaces studio microphones, line-level sources, musical instruments, and
consumer audio electronics with personal computers. Its high-quality, 24-bit
audio inputs offer the most direct signal path into the computer. All
analog-to-digital conversion is done outside of the computer, in the USBPre,
for superior audio performance. S/PDIF coaxial I/O enables direct digital
transfers into and out of the computer.
USBPre has the flexibility to work with most Windows and Mac recording,
streaming, and measurement software. Powered solely by the USB port from
either notebook or desktop computers, no additional power source is required
— the computer provides all power needed for operation. The durable
construction and compact size of the USBPre allow no-compromise digital
recording everywhere.
USBPre- Features
- Dynamic range greater than 106 dB (in 24-bit operation)
- Flat 10 Hz to 22 kHz audio bandwidth
- Exceptionally low distortion characteristics
- Two inputs accept microphone, instrument, line, or tape level
inputs
- Input type is selected per channel — allowing two different signal
types simultaneously
- Phantom power (48 volt) for condenser microphones
- S/PDIF coaxial input and output
- Six-segment LED peak input meter
- High-power headphone monitor
- Mix control enables headphone monitoring of analog source audio,
computer audio, or a mix of both source and computer audio
- Phono (RCA) jacks connect PC AUDIO output to external loudspeakers or
preamplifiers
- Bus powering from the USB port eliminates external power sources and
batteries
- High-strength extruded aluminum chassis
