 Step 1: What are Distribution Amplifiers?
 
Distribution amplifiers (DAs) split the video signal from one source into two or more signals. A common application for a high resolution video DA is to take the signal from one computer-video port and then amplify and split it so it can feed two or more high resolution data displays maintaining the original quality. DAs also provide amplification and enhancement features for signals such as peaking and leveling. Each of the outputs on Extron's DAs is buffered so the original signal will still retain its clarity and strength when split

To select the right DA for a specific environment, begin by identifying the following elements:

  1. What type of signal is being distributed?
  2. How many outputs are needed?
  3. How far is the signal being run?
  4. How does the DA need to be mounted?
  5. What are your space requirements?
When more outputs are needed than are available on a single DA, the amplifiers can be looped together. That means the output of one DA can be fed into the input of another.

  • Buffer - Generally referred to as a unity gain amplifier, a buffer is used to isolate the signal source from the load. A buffer can be used for digital or analog signals.
