The question of whether to remove splitters when using a Channel Master amplifier or preamplifier is a common one, particularly for those navigating the complexities of home signal distribution. The answer, unfortunately, isn't a simple yes or no. It depends heavily on your specific setup, the strength of your incoming signal, the number of outputs you need, and the type of Channel Master equipment you're using. This article will delve into the specifics, offering guidance based on common Channel Master models and installation scenarios. We'll examine signal loss from splitters, explore safe installation procedures, and provide insights based on the provided references: Channel Master CM-7777, Channel Master Titan 2, and the CM-3212HD/CM-3213HD amplifiers.
Understanding Signal Loss from Splitters
Before we address the splitter question directly, let's understand the impact of splitters on signal strength. A splitter, by its very nature, divides the incoming signal among multiple outputs. This division inherently results in signal loss. The amount of loss depends on the type of splitter (2-way, 3-way, 4-way, etc.) and its quality. A typical 2-way splitter will introduce a loss of approximately 3-4dB (decibels) per output. A 4-way splitter will result in even greater loss. This means that the signal strength reaching each television will be significantly weaker than the original signal.
The significance of this loss depends entirely on the strength of your initial signal. If you have a strong incoming signal, the loss from a splitter might be negligible and your TVs might still receive a perfectly acceptable picture. However, if your incoming signal is already weak, adding a splitter could result in a picture that is grainy, pixelated, or even unwatchable. This is where the Channel Master amplifiers and preamplifiers come into play.
The Role of Channel Master Amplifiers and Preamplifiers (CM-3212HD, CM-3213HD)
Channel Master amplifiers, such as the CM-3212HD and CM-3213HD, are designed to boost weak signals. They amplify the signal *after* it's been split, compensating for the signal loss introduced by the splitter. Therefore, in scenarios with weak incoming signals and multiple TVs, using a Channel Master amplifier in conjunction with splitters is often necessary. The amplifier essentially restores the signal strength to a usable level for each television.
When to Remove Splitters (and When Not To)
Now, let's address the core question: should you remove splitters when using a Channel Master amplifier?
* Scenario 1: Strong Incoming Signal, Few TVs: If you have a strong incoming signal (measured using a signal meter) and only need to distribute the signal to a few TVs (perhaps two or three), you might be able to eliminate the splitter entirely. In this case, running a direct coaxial cable from the antenna to each TV would avoid signal loss from the splitter. However, this requires running multiple cables, which might not be feasible or aesthetically pleasing.
