USING EXTERNAL COMPONENTS Using GENLOCK Functions This device features a GENLOCK IN terminal. Input external synchronization signals in the GENLOCK IN terminal to synchronize camera images or playback images with external signals. Additionally, the H (horizontal) and SC (subcarrier) phase adjustments can be performed on image signals of this device for external synchronization signals from the GENLOCK menu screen. GENLOCK functions are only valid in Camera mode. They do not work in VTR mode. GENLOCK/AUX IN switch GENLOCK/AUX IN terminal Connection „ During Standby or Stop mode, input synchronization signals from a Sync signal generator to the GENLOCK/AUX IN terminal. The following synchronization signals are applicable. SD synchronization signal: BB (Black burst) signals SMPTE170M (RS-170A)-compliant for NTSC ITU-R BT.470-6-compliant for PAL HD synchronization signal: HDTV Tri-sync signals SMPTE296M-compliant for HD720p SMPTE274M-compliant for HD1080i CAUTION • When the FRAME RATE is set to 60/30 or 24 in the VIDEO FORMAT[1/2] menu screen, input a 59.94 Hz synchronization signal (vertical synchronization). 50 Hz/ 60 Hz synchronization signals cannot be synchronized. If the FRAME RATE is set to 50/25, input a 50 Hz synchronization signal. 59.94 Hz/60 Hz synchronization signals cannot be synchronized. • Do not connect or disconnect the cable during recording or playback. • When the power is turned on while the external synchronization signal is input, a vertical vibration occurs for a few seconds. This is not a malfunction. • VTR playback signals with jitter cannot be synchronized with this device. Setting „ Set this device to Camera mode. „ Set the GENLOCK/AUX IN switch to GENLOCK. • When the camera image is locking to external synchronization signals, "SYNC LOCKING" is displayed on the screen. When locking to external synchronization signals is complete, the indication disappears and you can enter recording mode. 66 IEEE 1394 CH2-AUDIO OUT-CH1 VIDEO Synchronized Signals The synchronized signal differs depending on the input sync signal.

Adjust SC and H PHASE 1. Display the GENLOCK menu screen. Follow the steps in "Setting Menu Screens" on page 75 and proceed as follows. MENUrOTHERSrGENLOCK 2. In the GENLOCK menu screen, select the item to per- form phase adjustment for and adjust. SD H PHASE : Adjust the H phase in SD analog signals. (During BB signal input) HD H PHASE : Adjust the H phase in HD analog and SD/ HD SDI signals. (During Tri-sync signal input, PHASE of SD analog signals are simultaneously adjusted in HD H PHASE item.) SC PHASE : Adjust the SC phase in composite and YC signals. For details, refer to "GENLOCK Menu Screen" on X See page 99. MEMO • H PHASE cannot be adjusted during playback or recording. • IEEE1394 output stops while H PHASE is being adjusted. • When values for SD H PHASE or HD H PHASE is changed, the images cannot be produced properly momentarily. This is not a malfunction. Dubbing with AV Devices VIDEO FORMAT menu screen By connecting the video signal output terminal and the AUDIO OUTPUT terminal on GY-HD250/GY-HD251 to an AV device, analog signal dubbing is possible. 1. Connect the cables. To reduce the emission of unwanted radio waves, be sure to attach the provided clamp filter as shown in the figure below. • Attach the clamp filter as close to this device as possi- ble, as shown in the figure. Composite cable or Component cable CH2-AUDIO OUT-CH1 VIDEO Audio cable IEEE 1394 AUDIO OUTPUT connector Signal flow Recording unit Signal flow Clamp filter 2. Turn both devices on. 3. Set this device to VTR mode. Press the CAM/VTR button. The VTR indicator lights. 4. Set the video output. Set the VIDEO FORMAT menu screen. X See page 77. • HDV PB OUTPUT item: Set the video format to be output from the video output terminal during tape playback. • PB TAPE item: Select whether to automatically detect the playback tape video format or play back only a particular format. Normally, use the "AUTO" setting. • OUTPUT TERM. [DV] item: Set component, RGB or Y/C signals for the output image signals of the [Y/PB/PR] terminal. (Only for DV format) 5. Set the audio output. X See page 63. Set the AUDIO menu screen. X See page 87. AUDIO menu screen • PB AUDIO CH [DV] item: Set the audio channel to be output. 6. Insert the videocassettes. GY-HD250/GY-HD251 Recording unit : Insert the recorded videocassette. : Insert the videocassette to be dubbed to. 7. Press the PLAY/STILL button on the GY-HD250/GY- HD251 to start playback. 8. Start recording on the recording unit. For details, see the instructions to the unit used for recording. 9. When dubbing is completed. Stop recording on the recording unit, and then press the STOP button on the GY-HD250/GY-HD251 to stop playback. 67
