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 loop-
through inputs designed to remove common
mode hum induced by cable runs adjacent to
AC mains cables.
