[. . . ] 4 THREE YEAR LIMITED WARRANTY WARRANTY AND SPECIFICATIONS ® DMM 806 VIDEO DEMODULATOR SYSTEM 1 R. L. DRAKE COMPANY warrants to the original purchaser this product shall be free from defects in material or workmanship for three (3) years from the date of original purchase. DRAKE COMPANY or an authorized Drake service facility will provide, free of charge, both parts and labor necessary to correct defects in material and workmanship. [. . . ] Drake DMM 806 is a professional quality agile television channel demodulator that provides an audio and video output from any VHF, UHF, or CATV channel (54 - 806 MHz). The modular design of the DMM 806 permits convenient pairing with a Drake Mini-rack Video Modulator to perform off-air or CATV channel processing. The desired off-air VHF or UHF television channel from 2 through 69 or CATV channel from 2 through 125 is selected by a front panel pushwheel switch and associated slide switch. The DMM 806 provides a standard negative sync video output at a nominal level of 1 Vp-p, and an audio output signal that is level adjustable from approximately 0. 5 to 1. 5 Vp-p with a front panel control. As previously described, channel selection switches and audio output level control are located on the front panel. The RF Input is through an "F" type connector located on the rear panel. The unit is powered by a compatible Drake Mini-rack power supply module. Output Impedance: GENERAL DC Power Input: Operating Temperature: Dimensions: Weight: +12 VDC @ 120 mA, +5 VDC @ 100 mA.

Figure 3 illustrates the use of the DMM 806 as an offair channel processor. For this purpose, the feed from a television antenna is connected via a 75 Ohm coaxial cable to the RF IN connector of the DMM 806. The front panel switches are set for "OFF-AIR" and the received TV channel number is set for 02 through 69 as required. The VIDEO OUT and AUDIO OUT signals are connected to the VIDEO IN and AUDIO IN connectors respectively of an adjacently located Video Modulator, such as a Drake Mini-rack Video Modulator, operating on the desired cable TV 3 channel. Alternatively, cable TV channels can be processed by connecting the 75 Ohm coaxial cable of a CATV feed to the DMM 806 RF IN connector and setting the front panel switches for "CATV" or "CATV +100" and the received cable channel number 02 through 125 as required. Additional channels can be processed by adding combinations of DMM 806 units with Drake Mini-rack Video Modulator units. RACK MOUNTING Adequate ventilation is very important in multi-channel installations. Units should be spaced apart by at least one panel height wherever possible, and some air movement is advisable in enclosed rack cabinets.
