EQ Distribution Amplifiers - ProSeries EQ DA 1개의 Composite 신호를 받아서 Gain 과 EQ를 조절하여 장거리 전송으로 인한 신호 감쇄현상을 보정하여 4개의 출력으로 전송하는 장비 Gain 조절 가능, DC - 25MHz 입력 : Composite 출력 : Composite 전원 : 10-24V AC or DC (포함)   Equalizing Composite Video Distribution Amplifiers & Line Amplifier Equalizing or "EQ" composite video amplifiers incorporate both variable gain and variable EQ to compensate for signal losses over long coaxial cable runs. Why Use an Equalizing Amplifier? Coax cable is ideal for baseband video signal transmission - over relatively short distances. Once the cable length exceeds 100 to 200 feet, cable losses can noticeably degrade picture quality. Attenuation over coax cable increases with the frequency, so the loss is not uniform across the video signal bandwidth. The high frequency loss or "roll-off" in a long cable run decreases video resolution. Sharp lines become blurry, and contrast is lost. Ghosts may appear along straight lines, or where there is significant contrast on the original signal. Text is particularly degraded, as both contrast and resolution are critical to presenting crisp, readable text on a video display. Because different cable types have different loss characteristics, VAC offers both the Basic Block™ Line Drivers and ProSeries™ EQ DAs in versions optimized for RG-59, RG-6 or 8281 type cable. The Basic Block EQ Line Amplifier is an ideal solution when only a single output is required. The ProSeries EQ DA incorporates a 1X4 DA, and a differential input to mitigate ground loop interference.
