Sound Devices 722 Portable Digital Audio Recorder  From Sound Devices

Powerful Stereo Field recorder including a 160gig Hard Drive

Sound Devices

Manufacturer's Description from Sound Devices

The 722 two-track file-based digital audio recorder is designed for applications where high-resolution audio capture is essential in a portable, durable device. This compact recorder is known for pleasant-sounding low-noise microphone preamplifiers, and the flexibility to record to its internal hard drive and removable Compact Flash cards.

 

722 Key Features

Storage On Board

With the onboard hard disc drive, the 722 is always equipped with available storage media. That is among many included features, along with its small size and durable construction, provided by the 722 for high-resolution portable audio capture. Sharing a common menu architecture with the 7-Series family of recorders, the 722 is intuitive to operate. Powering by external 10-18 VDC or Sony-compatible camcorder battery allows flexibility for use in portable and studio applications alike.

Data Storage and Transfer

The 722 records uncompressed PCM or compressed MP3 audio to its internal hard drive, a Compact Flash card and an external FireWire drive simultaneously. It can be connected to Mac OS or Windows computers with FireWire 400 for high-speed data transfer.

7-Series Family of Recorders

The 7-Series Recorders possess unmatched capability in compact packages, each designed for unique user requirements. As with other 7-Series Recorders, the 722 can be used as a stand-alone device, fed by numerous analog mic, line, or digital AES-3 outputs, or preceded by a portable audio mixer such as Sound Devices' 552 or 302.
