CDR Burner Professional Stand-Alone CD-R/RW Recorder with Balanced Analog I/O, AES/EBU I/O, Wordclock Input The CDR830 Plus is a stand-alone professional CD burner featuring high precision 24-bit analog to digital and 24-bit multi-level Delta Sigma digital to analog converters. The unit's specifications are exactly the same as for the CDR830 except for the addition of XLR balanced analog inputs and outputs, AES/EBU input and output and the addition of a WC BNC input. The design of the laser assembly means that every single CD-R and CD-RW disc written is very accurate, providing greater compatibility with other CD players and recorders. Solidly built for studio use, the unit records on readily available, low cost discs and features a SCMS-free digital input.
