DESTRIPTION :
The WSM-3U modulates a video and left or right audio signal where DVD, VCD, or CCD Camera to a  user desired TV. The modulator has a double sideband and 90 dBuv output that is free from spurious distortions. The WSM-3U incorporates a commercial grade design intended for non-adjacent placement of modulated channel in free area of CATV band or TV band. The microprocessor controlled Phase Locked Loop (PLL) circuit allows selection of the output channel to be made from the front panel. The selected channel number is channel displayed in the selection window. Non-volatile memory locks and holds the selected channel even after a power outage. The LED display and channel up/down button permit easy selection of the desired channel(s).   

FEATURES:

 　

◆ Professional Picture Quality

◆ Full 90dBuv Output

◆ Agile Channel Selection Via Front Panel Control and LED Display

◆ Low Spurious Harmonic Output

◆ Non-Volatile Memory Retains Channel Information During Power Outages

◆ Comply to CCD Camera Metal Housing
