Designed to make local origination easy, the Drake VMD860AG and VMD860AS desktop audio-video modulators are perfect for portable or temporary video installations such as a video cart or suitcase videographer.

This modulator series is popular in schools, institutions, and with CATV companies because the frequency agile VMD860AG and VMD860AS allow front panel pushwheel switch selection of standard CATV channels 2 through 135, CATV subband channels, T7 through T14, or VHF/UHF TV channels 2 through 69. This means the local operator can utilize "T" channels to return local origination programming to the control headend or generate signals on the desired operational channel.

These Audio-Video modulators are high quality, vestigial sideband units with synthesized visual and aural carriers. The aeronautical channels are offset positive with a tolerance of ±5 kHz as required by FCC rules.

The heterodyne conversion system, in conjunction with the use of a SAW filter, ensures optimum vestigial selectivity for adjacent channel headends.

These modulators are designed to accept any standard audio/video source such as NTSC video and audio baseband signals from a satellite receiver, TV camera, videotape recorder, TV demodulator, or similar signal source.

The VMD860AG or VMD860AS modulator is designed to accept standard (negative sync) polarity video at 0.6 to 1.5 Vp-p level. All level controls are located on the front panel for ease of operation. Audio and video overmodulation indicators are provided. Output level is +45 dBmV and is adjustable over a 10 dB range.

Field-defeatable audio pre-emphasis in the VMD860AG allows transmission of BTSC encoded baseband stereo audio signals using a Drake stereo encoder. The AUDIO INPUT can also accept a 4.5 MHz audio modulated carrier by changing internal jumpers.

The VMD860AS accepts stereo audio inputs and generates a BTSC stereo audio signal without an external encoder.
