![]() ![]() However, if a system works well with a parallel split, this type is popular because they are simpler to construct and do not require employing isolation transformers - an added expense. Also, differences in the impedances of the legs in active balanced inputs of multiple consoles can make the system more susceptible to hums and buzzes caused by outside interference. Most modern consoles behave well when connected to each other but keep in mind that there is no DC isolation between them. This method successfully connects the mic to multiple mixing consoles but connects the consoles directly to each other as well. This involves taking a mic cable and simply "Y" connecting the plus, minus and ground wires to two other cables. The simplest form of splitter is the parallel type split. There are two types of passive splitters: parallel and transformer isolated. This is called passive splitting - no power required.Īctive electronic splitters will most likely be required when splitting microphones to four or more consoles. The number of splits that can be accomplished depends on the application, impedances present in the system, length of the cables and the quality of the components used in the splitter. Microphones can usually be split to up to three, and in some cases even four, destinations without the use of electronics. (See tech article "High and Low Impedance" for a more detailed explanation.) This actually increases the overall load presented to the mic signal and limits how many times it can be split without degrading tone or introducing distortion. When a signal is split to be sent to more than one mixing console, the input impedances of those consoles provide additional paths for the electrical current. Proper design of signal flow in an audio system dictates that low impedance outputs (mics) feed high impedance inputs (mixers). In any event, you'll most likely need to split your mic signals and feed more than one mixing console. That mix will be at its best if the person providing it is isolated from the confusion of hearing the live sound. Or you may be called upon to provide a separate mix for recording or broadcasting your performances. Although it's possible to provide a separate monitor mix from the main console, a person located nearer to the performance area can hear what the performers hear, see their cues more easily and just generally be able to provide a better monitor mix. ![]() In this article we just might add some additional terms to your audio vocabulary as we discuss microphone splitters.Īs your sound system expands, it will eventually be necessary to provide additional mixes from locations other than the main mix position. ![]() have become part of the sound team's vocabulary as they strive to provide today's expected level of sound quality and production - for both the listeners and the performers. Words like "direct box", "balanced", "low impedance", "crossover", etc. Many have replaced that powered mixer with separate components and added a snake to allow for a mix position in the listening area. If your band, school or church's sound system has evolved along a familiar path, what started out as a pretty simple, small group, "sound-on-a-stick" has gradually become more and more sophisticated.
