ONE YEAR LIMITED WARRANTY

R.L.DRAKE COMPANY warrants to the original purchaser this product shall be free from defects in material or workmanship for one

(1) year from the date of original purchase.

During the warranty period the R.L.DRAKE COMPANY or an authorized Drake service facility will provide, free of charge, both parts

and labor necessary to correct defects in material and workmanship. At its option, R. L. DRAKE COMPANY may replace a defective

unit.

To obtain such warranty service, the original purchaser must:

(1)

(1) Retain invoice or original proof of purchase to establish the start of the warranty period.
(2)

(2)

(2) Notify the R.L.DRAKE COMPANY or the nearest authorized service facility, as soon as possible after discovery of a possible

defect, of:

(a) the model and serial number,

(b) the identity of the seller and the approximate date of purchase; and

(c) A detailed description of the problem, including details on the electrical connection to associated equipment and the list of such

equipment.

(3)

(3) Deliver the product to the R.L.DRAKE COMPANY or the nearest authorized service facility, or ship the same in its original container

or equivalent, fully insured and shipping charges prepaid.

Correct maintenance, repair, and use are necessary to obtain proper performance from this product. Therefore carefully read the

Instruction Manual. This warranty does not apply to any defect that R.L.DRAKE COMPANY determines is due to:

(1)

(1) Improper maintenance or repair, including the installation of parts or accessories that do not conform to the quality and

specifications of the original parts.

(2)

(2) Misuse, abuse, neglect or improper installation.
(3)

(3)

(3) Accidental or intentional damage.
All implied warranties, if any, including warranties of merchantability and fitness for a particular purpose, terminate one (1) year

from the date of the original purchase.

The foregoing constitutes R.L.DRAKE COMPANY’S entire obligation with respect to this product, and the original purchaser shall

have no other remedy and no claim for incidental or consequential damages, losses or expenses. Some states do not allow limitations

on how long an implied warranty lasts or do not allow the exclusions or limitation of incidental or consequential damages, so the above

limitation and exclusion may not apply to you.

This warranty gives you specific legal rights and you may also have other rights which vary from state to state. This warranty shall

be construed under the laws of Ohio.

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.
