The DSR-45 provides two selectable audio channel modes; a two-channel mode with 48 kHz/16-bit

recording and a four-channel mode with 32 kHz/12-bit recording. Thanks to its PCM (Pulse Code Modulation)

digital stereo recording system, the DSR-45 offers superb digital audio performance with a wide dynamic

range and an excellent signal-to-noise ratio, comparable to CD-quality audio.

user to play back DV recorded tapes on the DSR-45. Such versatility is quite advantageous to users working with DV

cameras for their great portability and long recording times.

The DSR-45 has a dual-size cassette mechanism, which accepts both mini and standard size DVCAM and DV

cassette tapes without any special adaptor. This innovative feature allows the four different types of

cassette tapes to be used without the cumbersome process associated with additional mechanical hardware.

Capability of Recording in DV(SP) Format

Should you require a longer record time than what is available with the DVCAM format, the DSR-45 is capable

of recording in the DV format. In this format, a standardsized cassette records up to 270 minutes.

i.LINK Interface
The DSR-45 is equipped with a 4-pin i.LINK (DV) interface based on the IEEE 1394 standard.

The DSR-45 uses the DVCAM format, the professional extension of the worldwide standard DV format. The

DVCAM format uses 8-bit digital component recording with a 5:1 compression ratio and a sampling rate of 4:1:1

(for 525/60)/4:2:0 (for 625/50). The unique compression algorithm provides excellent picture quality and superb

multi-generation dubbing performance.

long recording times are achieved by using Sony advanced ME (Metal Evaporated) tape.
