Description
The Sony BVW-70 is a Betacam SP studio edit recorder/player introduced by Sony in 1987 as part of the original Betacam SP equipment lineup. It is the standard edit recorder of the BVW series, offering comprehensive recording and editing capabilities in the Betacam SP format.
The BVW-70 records and plays back using both metal particle tape (Betacam SP) and oxide tape (original Betacam) in L-size (90+ minutes) and S-size (30 minutes) cassettes. Four audio channels are available: two longitudinal tracks with Dolby C noise reduction and two AFM tracks with wider frequency response (20 Hz to 20 kHz) and greater dynamic range.
Built-in editing facilities support insert and assemble editing with auto preview/review, audio split editing with independent in/out memories, frame-accurate trimming, and selectable pre-roll time. The deck can remotely control other RS-422-equipped VTRs as source machines. Two independent SC-H phase indicators are provided for composite input and output monitoring.
The BVW-70 provides both VITC and LTC timecode generation and reading in SMPTE standards with user bits. A built-in TBC with digital dropout compensation ensures broadcast-quality output. The BVW-70 is essentially the same as the BVW-75 but without Dynamic Tracking capability.
