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

4.3 VIDEO LEVEL SWITCH
4.1 SYNC POLARITY SWITCH
The VIDEO LEVEL Switch can be set to either
the standard 0.7V output or to 1.0V output.
When the switch is set in the 1.0V output
position, this provides approximately a 35%
increase in the video signal level. This can be
used in installations where cable runs exceed
150 feet. It is not recommended that this switch
be set in the 1.0V position for shorter cable
lengths as the increased level may reduce the
life of CRT displays if they are overdriven.
The SYNC POLARITY switch is located on the
back panel of the unit. It has two switching
positions, one designated (+) and the other (-).
By setting the sync polarity switch to (+) the
signal is processed as unchanged and the sync
polarity of the output signal is matched with the
sync polarity of the unit. By setting the sync
polarity to (-) the sync polarity of the output is
changed to the opposite of the input.
4.2 SYNC LEVEL SWITCH
4.4 POWER
The SYNC LEVEL switch is also located on the
back panel of the unit and has two positions for
switching — a sync level of 2V and a sync level
of 4V. Most often a 4V-sync level is used. This
should be considered as the default setting. The
2V setting allows compatibility with some older
equipment that would be overdriven if a stronger
signal were used.
The DA1206RM offers an internal 90-140/200-
240V power supply. A variety of different power
supplies are available for international use.

The settings of the DA1206RM Distribution
Amplifier can be adjusted using Input Termination,
Video Level, and Sync Level switches as described
in Section no. 4. There are no other adjustments
necessary to operate the unit. The DA1206RM will
operate successfully as long as cables are
attached properly and other technical specifications
are followed.
Step 1.
Step 2.
Step 3.
Make sure that the proper power supply
is being used with the unit. The use of
an incorrect power supply can result in
equipment damage not covered by
warranty.
Connect the power cord to the unit and
plug it into the power outlet. The power
indicator LED on the front panel will
light. This indicates that the unit is
operational.

coaxial cable with BNC connectors,
making sure that the colors match
correctly. Then connect one or two
monitors or projectors to the output(s) of
the DA1206RM. The monitors or
projectors must be scan-rate compatible
with the source signal - the DA1206RM
does not affect scan rate.

If the image is less than perfect, check
all of the connections. Also, check the
settings of the switches. The default
setting is Sync Polarity (+), Sync Level
(4V), Video Level (0.7V). Check all of
the connections. The unit is very reliable
and seldom will be the cause of
malfunction. Poor quality cables may
often degrade the performance of the
product. Make sure that the cables used
are coaxial cables and that all pins are
in good condition.
