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 reclocking. 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 loopthrough inputs designed to remove common
mode hum induced by cable runs adjacent to
AC mains cables.
