Should a component failure cause down time on TV transmitting equipment, stations utilizing S -E TRANSMITTING EQUIPMENT WITH EXCLUSIVE PATCHOVER can return to the air more quickly and prevent the nightmare of complaint calls from sponsors, agencies, viewers ... minimize loss of station revenue! of the telecasting *down time on, transmitting equipment The unique Patchover System incorporated in Standard Electronics transmitting equipment enables stations to re -route RF signal the moment an amplifier fails. This system is based on identical impedances at the input and output of SE amplifiers. The inoperative amplifier can be immediately patched out and the remaining transmitting equipment then connected to the antenna for temporary reduced power operation ... all in a matter of seconds! Thus, telecasting can continue while amplifier maintenance is performed. With this system, a station can also utilize an S -E Driver for full power standby service .. . eliminating the need for a costly transmitter line -up solely for standby! And the savings that result from the first time you might be called upon to use Patchover ... may more than offset the cost of the entire transmitter! There is less likelihood of transmitting failures with superbly engineered Standard Electronics transmitters and amplifiers. Will you be prepared should failure occur with your present equipment? Insure your operation against costly air time loss ... with Standard Electronics Transmitting Equipment- featuring exclusive Patchover. <strong>Com</strong>plete details on request. HOW PATCHOVER WORKS D Ai At F',, I I 1 F 2 WITH AMPLIFIER FAILURE Dotted line in Fig. 1 show patch -out of inoperative amplifier Ai. Similar procedure shown in Fig. 2 applies if failure occurs with amplif'er Af. The entire diagram shows patch -out procedure i the event both amplifiers should fail; driver is connec ed to antenna for reduced power operation. D A Al tondby Dr iver WITH DRIVER FAILURE Dotted line indicates patch -over procedure called for by driver failure. Patch -over is made from amplifier Ai to the standby driver. Patch -over is done in seconds .. . requires just a screw driver! standard electronics corporation A S U B S I D I A R Y O F D Y N A M I C S C O R P O R A T I VHF TV Transmitters VHF TV Amplifiers high bond low bond high bond low bond 500 W 500 W 10 KW 10KW 10 KW 10 KW 25 KW 25 KW 25 KW 25 KW 50 KW 50 KW 50 KW 50 KW O N O F AMERICA, I N C. 285 -289 EMMETT STREET NEWARK 5, NEW JERSEY Tele -Tech & ELECTRONIC INDUSTRIES June 1956 For product information, use inquiry card on pages 209 -210 33
