The R.L. Drake mini-rack system is a professional quality, modular headend system, designed to optimize rack space. The VMM600 and VMM860 are high quality, fixed channel, heterodyne audio/video modulators. One to twelve can be mounted in the same amount of rack space typically required for two standard size units. Ideally suited for private cable, hotel/motel, institutional, and SMATV applications, the VMM600 and VMM860 accept standard NTSC video and audio baseband signals from a satellite receiver, TV demodulator, or similar signal source.
