DSB Modulator for S-channels BM450

Naval’s new double side band S-channel TV modulator BM-450 is designed for operation in the frequency range of 245.25-463.25 MHz in PAL B/G, D/K, I, and NTSC M/N systems. High adjustable output level is significant for this unit. The modulator is equipped with two individual input level adjustments for video and audio signal. Front panel control switches for easy setting of output frequency and all video, audio and RF outputs in the front for easy connection. The module can be installed into a cabinet or separately. Please contact Naval for more detailed information.
