ABOUT YOUR DISTRIBUTION AMPLIFIER 2
The DA1206RM Distribution Amplifier is designed
to allow the connection of a single computer or
other video source to as many as six scan-rate
compatible display devices.
Though primarily designed to pass RGBS format
signals, the DA1206RM can also pass RGsB,
Component Video (Y, R-Y, B-Y), S-Video (Y/C),
and Composite Video by using the appropriate
analog channels (Red, Green, Blue).
The analog channels are designed to pass video
levels up to 1.5V p-p offering a 0.15% differential
gain and 0.16 degree differential phase to assure
the highest quality video signal.
The DA1206RM offers switches for Gain, Sync
Level, and Sync Polarity. The Gain switch boosts
the output of the amplifier by 35% for use with long
cable runs. The DA1206RM uses AGC (automatic
gain control) circuitry, which converts all incoming
sync levels to either 4V p-p or 2V p-p, selectable
with the Sync Level switch. This enables it to be
compatible, with both current and older display
equipment. The Sync Polarity switch reverses the
polarity of the incoming sync for compatibility with
various displays
The DA1203RM Distribution Amplifier is a state-of-
the-art product with a video bandwidth of 350 MHz,
enabling it to remain transparent to the video signal
passing through it. Each output is individually
buffered and is not affected by other output
loading.
The DA1206RM offers an internal 90-140/200-
240V power supply and can be rack mounted using
optional hardware accessories (DA1299RM – rack
ears for single unit and DA1298RM – rack shelf for
two units side-by-side).
