GeckoFlex 8901 Utility Analog Video Distribution Amplifier

This distribution amplifier is ideal for short cable runs of high-quality signals. Its flat frequency response and very impressive signal-to-noise ratio ensures high-quality copies to all eight outputs. The AC coupled mode is used when the incoming video signal has a blanking level at anything other than zero volts. For handling color-difference signals (B-Y, R-Y), DC input coupling is recommended. Additionally, the 8901 module can be used for simple fanout distribution of AES/EBU 1 Vp-p coaxial digital audio signals that do not need re-clocking. The bandwidth of the 8901 easily handles the 6 MHz frequency response required by professional 48 kHz AES/EBU digital audio signals. Our entire line of both analog and digital distribution amplifiers offer passive differential loop-through inputs designed to remove common mode hum induced by cable runs adjacent to AC mains cables.
