1. Place your betacam source tape in deck B (BCB 60).

2. On the JVC switcher push BCB 60 buttons on all buses.

3. Callibrate the audio on the source deck, the mixer, and the recorder.
   Both Ch 1 & 2, should have tone set at 0 db.

4. When you dub you want to MIX the sound (both channels in one). To do this, use the little black knobs on the mixer, called trim pots:
   • Check equalization controls: for no equalization, trim pots are in upright position (detent).
   • Verify stereo/mono:
     
     • stereo = pan trim pots -> left channel left, right channel right.
     • mono = pan trim pots in upright ('mixed') position. <-- this is what you want
   • adjust the 2 white sliders that correspond to BCB60 so they are at the same level as the 2 far right sliders (the L R output sliders). This is called unity gain.

5. Now adjust the colors. You have to set the video levels on the source deck's Time Base Corrector (TBC), so pull out deck B.
   
   • For variable control, the SET-UP switch is put into manual position and levels adjusted to CBARS. ????? Use little knob to adjust and look at your results on the waveform.
   • For unity gain (no adjustment), the preset switch is selected.
   • Video control adjusts 'white' or luminance level , SET-UP adjusts 'black' level.
   • On the waveform: for split-field color bars, white should be at 100%; for regular bars, white should be set to ~80 ire. Black or 'pedestal' level should be set to 7.5 ire or 'cheated' to 5 ire for 'richer' blacks (black is a 'legal' broadcast signal if it is somewhere between 0 and 7.5 ire).

6. Make sure that the image is centered. To do this:
   Create a horizontal wipe between the switcher color bars and the source deck. This is accomplished by pressing the wipe button on the JVC switcher, moving the lever to half way between the program and preset bus, and selecting a horizontal wipe. The record monitor should be in underscan mode to verify picture 'position'. Check the left edge of your signal (the color bars) on the monitor. If the two signals are not aligned, adjust by using the 'sync' knob on the source TBC so that the horizontal phase of the source signal can be aligned to that of the switcher or 'edit system'. Return the switcher to full screen program out.

7. Take care of time code on destination tape:
   If your record tape is not 'striped' (have time code already) you should set the time code for an assembly or 'crash edit':
   
   • Pull up the recorder deck completely.
   • Under the front control panel, on the top circuit board, the 4th switch is labelled regen/preset. This should be set at 'preset' mode. (If you want an assembly edit, set it to 'regen').
   • On the front control panel hit the record button to display the existing preset time code value.
   • To zero the preset value, use the reset button (to the right of the time code display).
   • Last hit the preset button (to the left of the time code control section).

8. Finally hit Play on the source deck B and Play & Record simultaneously on the destination deck (recorder).

The video editing suite allows you to make multiple dubs at a time. You can dub from Betacam to both VHS decks and the Hi8 all at once.

1. You have to use the betacam player BCB60 (deck B) as your source to make VHS dubs.

2. On the Nova 950 (located above the recorder deck) select the BCB60 button.

3. On the Extron 'dubbing' matrix switcher (located directly to the right of the dubbing decks -see image) select:
   • on the INPUT (top row) press DPS290. This is where the video/audio is routed from the Nova 950 to the dubbing decks.
   • After selecting the INPUT, the OUTPUT group of selections (lower row) will light up to show where the Nova is being routed to. Select VHS1 (or/and VHS2, Hi8) accordingly (or deselect the ones you don't want).
   • When finished, hit enter (right side of Extron) to 'load' the configuration.

4. Adjust audio and video on source deck (BCB60) as described in Betacam to Betacam dubbing above.

5. Adjust the audio input on the VHS/Hi8 recorder/s. Make sure you that the METER switch on the VHS is switched to 'normal' and not hi-fi. Hi-fi is not connected. Play your tone on the source and adjust the knobs on the VHS, so the VU needles are around 0.

6. Finally hit Play on the source deck, and hit and Play & Record simultaneously on the dub decks to begin recording.

7. Monitor your recording by using the dubbing monitor, select VHS1 or VHS2. Audio is automatically routed to the monitor speaker - volume controls are on the front monitor control panel. Headphones can also be used to monitor the audio.

The procedure is similar to the above (from BETACAM to Hi8 or/and VHS) except for:

1. Your source is now on the VHS or Hi8 decks and your destination is in the Betacam recorder.

2. On the DPS 290 (located above the recorder deck) select the Hi8 button.

3. The Extron dubbing matrix should be configured like this:
   
   • on the INPUT (top row) press Hi8 (or VHS1).
   • on the OUTPUT (lower row) press DPS290 (for the picture).
   • on the OUTPUT (lower row) press DPS 290 (for the audio).
   • When finished, hit enter (right side of Extron) to 'load' the configuration.

3/4" video/audio are connected as a source to betacam, and from betacam to 3/4".

The 3/4 inch deck is now configured as input and output number 7 on the S-Video matrix switcher. You may note the the 3/4 inch is not an S-video device, it does not produce a seperate luminance and chromanance signal, nor does it recieve separate signals. After a little thought I decided that there was no reason that you couldn't put a "T" connector on an S-Video signal and get composite video. As long as the two signals had the same cable length and used the same sync, it should be fine. So on both the 3/4 and the Hi-8 (which also doesn't use S-Video in or out) the Y and C are combined using the methods mentioned above.

The outputs however are still only composite, so they are not compatable with the other components in the matrix. I found out something interesting out though while I was messing around. Both of the Sony S-VHS decks are smart enough that if they recieve composite video on the Y or lumanince channel they just display composite. They're great decks. So if you want to go from/to Hi-8, S-VHS, VHS, 3/4 or from laser disc you can make those dubbs using just the matrix switcher.

The place where this doesn't work is in going to the beta decks. The S-Video routing to the Nova 750 and DPS-290 will not take composite on the Y channel. I guess they are not as smart as the Sony decks. Both the Hi-8 and 3/4 are routed to seperate inputs on the Nova and DPS for use when sending one of those formats into the suite or to betacam. The Hi-8 routs into the Nova, the input is labled. The 3/4 inch deck is patched into the NOVA950's NTSC input. If you switch the matrix so that they s-video version is routed to either of the frame sync's (Nova or DPS) they will display an image, but the colors will be very funky.

The audio while in the dubbing matrix works with just the push of a button, if you send the VHS to the 3/4 the audio will go also. This is not true going to the Beta decks. In order to do that you must install a patch cable either from the Matrix output (labled on the patch bay) to the destination Beta deck or to the input on the mixer (also labled on the patch bay.)
