How to Use Multiple Speakers On one Cabling do you Or Stereo Amplifier

This is ultimately easy, but before explaining the process I’m it is necessary to provide a warning. Multiple sets of speakers usually can’t be absolutely hooked on to a standard audio amplifier without some sort of impedance matching device. This is in mention of those persons whom should run speakers in several rooms at the same time (distributed audio). If several sets of speakers are run collected from one of set of speaker terminals the amplifier will most likely overheat and banned, and may blow the output stage (see footnote 1) خرید اسپیکر. These opinions do not connect with PA style amplifiers with 25 or 75 volt components, which require special speakers with transformers.

The correct solution is ty trying either an impedance matching speaker selector with the protection empowered, or use impedance matching in wall volume controls. Notice the underline in the word above. This is because most speaker selectors are made with a dangerous feature: a button, right in front, to disable the protection. If the switch was in back to prevent animal deactivation of the speaker protection it would be much better. If the protection is accidentally powered down while running multiple pairs of speakers the amplifier will banned, may blow output joins, and also well may damage the output stage of the amplifier. There are really only 2 reasons to turn this pull the plug on, the most relevant being that impedance matching volume controls will be come with ALL pairs of speakers. The other reason would be anxieties one pair of speakers will be run, making impedance matching unnecessary. In this event, though, leaving the protection switched in will make a tiny difference to the sound, why then not leave it on?

Remember it this way: only put one speaker per pair of terminals (usually red and black) on the amplifier. Do not try to use a revolve around amp to feed several rooms with one room on the center, one room on the raise surrounds etc. This is due to the way a revolve around device redirects the sound as you may end up with only the voice in one room and only the music in another! The correct hookup for a revolve around device puts revolve around sound however room and sound from the left and right main speakers is distributed. My recommendation for setting up a revolve around device is usually as follows. Run the speaker selector from the front left and front right components on the amplifier. Hook your front left & right speakers to the first speaker activate the speaker selector. You will need to re-balance your revolve around system by running the pink noise test as the speaker selector will decrease the output to the left and right speakers by a touch. This will give running the main speakers & the other speakers linked with the speaker selector without one set being louder than the others. If your speaker selector has volume controls, you must make sure when you use your revolve around system for movies the quantity control is in the same setting it was when doing the pink noise test. You may hook the speaker selector to the ‘b’ speaker activate the amplifier if speaker volume balance relating to the main left & right speakers and other speakers is easy.

Another variation is amplifiers with a direct speaker output for zone 2, 3, etc. These are set up to drive 1 pair of speakers, and must be used with impedance matching if more pairs will be used. The zone components allow a second (or third etc) source, for example CD in one room and radio in another.

An impedance matching speaker selector provides multiple components collected from one of input, and protects your amplifier from damage. Speaker selectors come with 4-12 components. As long as your amp has enough power, you can push as many sets of speakers as you want. Simply connect the speaker selector to your ‘A’ (or ‘B’) components and the rest of your speakers on the speaker selector. You can purchase speaker selectors with volume controls for each individual speaker. Another option is in wall impedance matching volume controls, which require no speaker selector. Most of these are set with jumpers at install time, providing the correct matching. If you want to run more pairs of speakers than the speaker selectors or volume controls are made for (usually 12 pairs max. depending on the hardware) you probably want a second amplifier to run the second set of volume controls (or speaker selector) from.

So, what is impedance and impedance matching? (Warning: semi technical material ahead)

The music signal to your speakers is called alternating current (or AC), because it varies polarity and voltage. This is in comparison to a battery, for example which produces a, or direct current. You may picture current as the amount of water flowing in a line (the wire) and voltage as the water pressure. Alternating current can be imagined as a flow that reverses direction and direct current as a steady flow in one direction. The analogy is not exact but is close enough to get a picture of what is happening. Standard house current the united states reverses direction (polarity) at an interval (or frequency) of 60 times per second, measures as 60 Hz (Hertz). If you visit our site you can see this article with instructive diagrams included.

Your speakers have a certain amount of resistance to current. Imagine the resistance as a constriction in the line, restraining the flow. They have a DC resistance, named the voice coil nailers resistance, and resistance to AC is called impedance. Resistance and impedance values are measured in Ohms. Impedance is a complex sum of dc resistances, plus the resistance to various AC frequencies caused by capacitance and inductance (normal properties of electrical and electronic devices). It is usually specified for speakers as nominal impedance, and is referenced to particular frequencies. However, Bear in mind that today as resistance to AC for practical purposes. Enter into your esophagus rated at either 8 or 4 Ohms. Most home amplifiers prefer an 8 ohm impedance. Each time another speaker is added in parallel the impedance is reduced. Picture several water lines connected together to the same pump, obviously the flow from the pump increases (up to the limit of the pumps capability). The amplifier is the pump. Two 8 ohm speakers reduce the impedance to 4 ohms, four 8 ohm speakers reduce the impedance to 2 ohms, and so forth.

An amplifier expects (most require) a certain amount of resistance to current flow. The cheaper the impedance, the more current flows through the output stage of a typical amplifier. This usually flows directly by way of a transistor (or other amplifying device) and damages the transistor or protective resistors in the output stage. If you get lucky it only blows an output stage fuse. The moral of the story is always use an impedance matching speaker selector, (or volume control) and your amplifier will always see a safe impedance load.
