The DRACOM model DDA5542R is a broadband
distribution amplifier designed for indoor use in both
residential and commercial buildings where RF signal
distribution in the frequency range of 54 to 550 MHz
is required. A passive return path is also provided
with a frequency range of 5 to 36 MHz. The
DDA5542R has a gain of 42 dB. The amplifier
incorporates a push-pull hybrid output amplifier to
provide a high quality, low distortion signal for a cable
TV “drop”, or, the output of an SMATV headend.
Gain is variable within a specified range using the
Gain control. A Slope control is provided to slope
the frequency response. An output test connector is
provided for convenient monitoring of the signal path.
The amplifier circuitry is designed for maximum
stability and is housed in a rugged aluminum
housing. The unit operates from 24 VDC provided by
the supplied power supply. To facilitate installation, a
connector is provided in the cable between the
amplifier and supply.
Be careful not to break the controls or force the
screwdriver past the controls, as circuit damage
could result. These types of adjustments will
generally require monitoring of the signal path at the
test connector. The levels measured at the input
monitor connector are 30 dB lower than the input.
The levels measured at the output monitor connector
are 30 dB lower than the output. The output load
must be connected to the output connector before
measurement from the monitor output is accurate.
Gain settings must take into account the maximum
permissible output level of this amplifier unit for the
total number of input channels.Refer to the
CHANNEL LOADING CHART on page 4, for specific
information. The gain adjustment range is limited and
will not correct for unequal signal levels between
channels in the same band. Establishing relatively
equal signal levels between channels is essential.
The Slope control permits sloping the overall
frequency response to compensate for the effect of
increasing signal loss of the higher frequency signals
in a length of connected coaxial cable.

Installation:
1) Unpack the Distribution amplifier and power
supply.
2) Locate the Distribution amplifier to permit both the
required signal cable connections and power
connections. Note that the amplifier housing has
holes to permit mounting the amplifier to a wall using
screws, if desired. When mounting the amp on a
wall, position the amp so that the heatsink fins are on
the left and right sides and NOT on the top and
bottom. Unplug the power cord connector to facilitate
routing the cord.
3) With all cable connections made to the amplifier,
and the power supply cord routed, reconnect the DC
power cord and then plug the AC line cord into a
source of 120VAC, 50/60 Hz power.
4) Use a screwdriver to adjust the Gain and/or Slope
controls for the desired frequency response.
