The Drake DDAS542R Distribution Amplifier manual provides instructions for setting up, operating, and troubleshooting the amplifier, which is designed for indoor use to distribute RF signals in the frequency range of 54 to 550 MHz. It includes details on adjusting gain and slope controls, monitoring signal paths, and ensuring proper installation to avoid damage, along with a one-year limited warranty covering defects in materials or workmanship.
Manual Overview
The Drake DDAS542R Distribution Amplifier manual provides detailed instructions for troubleshooting, diagnostics, and adjustments. The amplifier, designed for indoor RF signal distribution in the 54 to 550 MHz range, features a variable gain of up to 42 dB and a slope control to adjust frequency response. For troubleshooting, the manual emphasizes the importance of monitoring signal paths using the provided output test connector, which measures levels 30 dB lower than actual input and output. Calibration involves adjusting the Gain and Slope controls with a screwdriver to achieve the desired frequency response, considering the maximum permissible output level based on the number of input channels. The manual advises ensuring equal signal levels across channels and using the Slope control to compensate for signal loss at higher frequencies. The amplifier operates on 24 VDC from the included power supply and requires careful installation to avoid damage to controls. The manual also includes a channel loading chart for reference.
Quick Issues Covered
- Diagnose power-up failures with 24 VDC power supply issues.
- Adjust gain and slope for optimal frequency response calibration.
- Trace circuits using schematics for signal path monitoring.
Overview
The DRACOM model DDAS542R is a broadband distribution amplifier designed for indoor use in residential and commercial buildings. It distributes RF signals in the frequency range of 54 to 550 MHz and includes a passive return path with a frequency range of 5 to 36 MHz. The amplifier has a gain of 42 dB and features a push-pull hybrid output amplifier for high-quality, low-distortion signal distribution. It is housed in a rugged aluminum casing and operates from a 24 VDC power supply. The unit includes gain and slope controls for adjusting the frequency response and an output test connector for monitoring the signal path.
Specifications
- Gain: 42 dB nominal, 40 dB minimum.
- Gain Adjust Range: 15 dB minimum.
- Frequency Coverage: 54 – 550 MHz.
- Flatness: + 1.5 dB maximum.
Controls & Indicators
The front-panel controls/indicators for the DRACOM DDA5542R Distribution Amplifier include Gain and Slope controls, and a Power LED indicator.
Installation / Setup
The installation of the DRACOM DDA5542R Distribution Amplifier involves several key steps. First, unpack the amplifier and power supply. The amplifier should be located to allow for necessary signal cable and power connections, with the option to mount it on a wall using screws. When wall-mounted, the heatsink fins should be positioned on the left and right sides. Ensure all cable connections are made before connecting the power supply. The DC power cord should be reconnected, and the AC line cord plugged into a 120VAC power source. Adjust the Gain and Slope controls using a screwdriver to achieve the desired frequency response. It’s important to monitor the signal path at the test connector, as levels measured at the input and output monitor connectors are 30 dB lower than the actual input and output. Proper gain settings should consider the maximum permissible output level for the total number of input channels, and the Slope control can be used to adjust the frequency response to compensate for signal loss in coaxial cables.
Operation
The manual provides basic usage steps for the DRACOM DDA5542R Distribution Amplifier. First, unpack the amplifier and power supply. Then, position the amplifier to allow for necessary cable and power connections, ensuring the heatsink fins are on the sides. After making all cable connections, route the power supply cord, connect the DC power cord, and plug the AC line cord into a power source. Use a screwdriver to adjust the Gain and Slope controls for the desired frequency response. The amplifier includes a gain control, slope control, and an output test connector for monitoring the signal path.

Safety & Warnings
WARNING: TO PREVENT FIRE OR ELECTRICAL SHOCK DO NOT EXPOSE THIS PRODUCT’S AC ADAPTER OR AMPLIFIER TO RAIN OR MOISTURE.
If this product is equipped with a three-wire grounding-type plug, a plug having a third (grounding) pin, the plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type plug.
Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product.
If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER OF AC ADAPTER OR AMPLIFIER. NO USER-SERVICABLE PARTS INSIDE.
