Up to four independent, high-quality, audio channels 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.
Playback Compatibility with the DV (25 Mb/s) Format ,Dual-size Cassette Mechanism The DVCAM format maintains playback compatibility with the consumer DV format.4 This compatibility allows theuser 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. Versatile Video and Audio Interfaces
i.LINK Interface T he DSR-45 is equipped with a 4-pin i.LINK (DV) interface based on the IEEE1394 standard.The i.LINK interface provides a digital link from the DSR-45 to a variety of compatible equipment including Sony DVCAM VTRs and third-party nonlinear editors. Signals including video, audio, time code, and control can be transferred through this I/O with virtually no degradation of image or sound quality. In addition, when the DVCAM cassette with IC memory is loaded into a DSR-45, the ClipLink(tm) data recorded on the cassette memory can be uploaded to a nonlinear editing system.6
Analog Component Input/Output and S-Video The DSR-45 provides a full range of analog video inputs and outputs; component, composite, and S-Video inputs and outputs are all available. The DSR-45 can also be used as a signal converter. Component, composite, and S-Video analog signals can easily be converted to and from i.Link digital signals.

The DVCAM Format, For Excellent Picture And Sound Quality
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-duration Recording Capability DVCAM videocassette tapes come in two sizes: standard and mini. A maximum recording time of 184-minutes is possible with a standard size cassette (PDV-184ME), while the mini cassette (PDVM-40ME) allows up to 40-minutes. Although the tape is relatively narrow, 1/4-inch (6.35 mm), and the cassette compact, these long recording times are achieved by using Sony advanced ME (Metal Evaporated) tape. |
