![]() Flatness can be degraded if unused ports are left unterminated. What is the total end-to-end insertion loss through these two combined splitters?īefore moving on, let’s take a quick look at definitions of some other common terminology applicable to splitters in general.Īdditional (or excess) insertion loss- Real-world splitters have somewhat higher insertion loss than what is calculated with the formula in the definition for “Insertion loss.” That additional or excess insertion loss is on the order of 0.5 dB to 1 dB (for a total insertion loss of 3.5 dB to 4 dB in a two-way splitter), and is caused by losses in the splitter’s internal transformers’ ferrite-core material and their very small gauge wire windings.īalanced splitter- A multiple-output splitter that has equal insertion loss or attenuation between the input port and each of the output ports.įlatness- A measure, in decibels, of amplitude-versus-frequency within the splitter’s passband. What’s the end-to-end insertion loss of this pair of splitters from input port to input port? The answer is at the end of the article.įigure 2. To get you thinking about that, consider the pair of back-to-back two-way splitters connected as shown in Figure 2. There is some “it depends” when it comes to the combined power, though. Here, RF signals from two sources can be applied to the two input ports (Ports 2 and 3 in Figure 1), and will appear at the single output port (Port 1 in Figure 1). ![]() In this usage, what were previously the splitter’s two output ports are now input ports, and the original input port is now the output port. However, the RF power level at each output port is approximately half of what it was at the input port.Īs well, a two-way splitter can be a power combiner. In the case of a balanced two-way splitter (more on “balanced” in a moment), when a radio frequency (RF) signal is applied to a splitter’s input port (Port 1 in Figure 1), the signal appears at equal amplitudes and with the same phase at each of the two output ports (Ports 2 and 3 in Figure 1). If you’ve ever wondered just how a two-way splitter works, grab a cup of coffee and read along!Ī splitter is a power divider. ![]() They’re part of the circuitry inside of some distribution passives such as taps and even other splitters! For example, a four-way splitter comprises a two-way splitter feeding a pair of two-way splitters. Those simple passive devices can be found on towers, in headends, hubs, the outside distribution network, and the subscriber drop. However, connecting more than two amplifiers with RCA is not generally recommended for most receivers.Two-way splitters have been used by the cable industry for decades. The number of RCA jacks that can be connected to one amplifier depends on the amplifier’s design and capabilities. How many RCA jacks can be hooked up to one amp? ![]() It features a distinct white and red (or sometimes yellow) plug design. FAQs:Īn RCA cable, short for Radio Corporation of America, is a connector used to establish audio and video connections between electronic devices such as TVs, stereos, and monitors. Additionally, consider the use of a Line Output Converter (LOC) for enhanced flexibility and safety. If connecting multiple amplifiers, opt for the three-way RCA splitter for superior signal distribution. Select the method that aligns with your goals, ensuring a seamless and efficient audio amplification experience. By comprehending the various approaches to connecting multiple amplifiers through one RCA jack, you can tailor your choice to your setup’s demands.
