SONY Editing Control Unit RM-450

Circa 1998

Professional video editing control unit.

Use Cases:

• Two-Machine Editing: The RM-450/450A was designed to facilitate two-machine editing, specifically controlling a playback VTR (video tape recorder) and a record VTR for "cuts only" edits.

• Precision Editing: It enabled precise synchronized editing, including CTL (control track), Time Code (SMPTE/EBU LTC/VITC), and Relative Time Code (RTC) editing modes.

• Split Editing: The unit supported split editing, allowing separate in-points for video and audio channels (A1, A2) for more refined sound and music edits.

• VTR Control: It offered remote control of basic VTR functions such as PLAY, STILL, FF, REW, STANDBY, EJECT (for 9-pin VTRs), REC, and EDIT.

• Compatibility: The RM-450/450A was compatible with various professional video formats, including U-matic and Betacam SP.

Connectivity:

• 9-pin RS-422 Interface: This was a primary connection for newer, 9-pin equipped Sony VTRs, allowing for both CTL and Time Code-based editing.

• 33-pin Remote Control Interface: The unit also featured 33-pin remote control connectors for direct connection to older 33-pin equipped editing VTRs, such as the Sony VO-5850/5800.

• Mixed Operation: The RM-450 was versatile enough to allow for mixed operation of both 33-pin and 9-pin equipped VTRs.

• Reference Video Input: It included a REF VIDEO IN (BNC) for synchronized operation with an external reference video signal.

• Cue Pulse Output: A CUE OUT (BNC) provided a cue pulse for triggering external equipment with external start capabilities.

Compatible VCR/VTR Types and Models:

• 33-pin equipped editing VTRs: The RM-450 can directly connect to VTRs featuring the 33-pin remote control interface, such as the Sony VO-5850 and VO-5800 U-matic decks.

• 9-pin (RS-422 serial interface) equipped VTRs: This includes a wider range of professional Sony VTRs, allowing for both Control Track (CTL) and Time Code-based editing. Examples include SONY VO-9850 series U-matics), VTRs compatible with professional formats like Betacam SP, DVCAM, and Hi-8 and specific 9-pin equipped Sony VTRs like the DSR-60/P, DSR-80/P, PVW-2600/P, and PVW-2800/P.
