This is ultimately easy, to start with explaining this process we feel it’s important to provide a warning. Multiple groups of speakers usually cannot be hooked straight away to a standard audio amplifier without some form of impedance matching device. This is in experience of those persons whom may want to run speakers in numerous rooms simultaneously (distributed audio). If several groups of speakers are run from a single set of speaker terminals the amplifier in most cases overheat and power down and could blow the output stage (see footnote 1). These remarks don’t apply to PA style amplifiers with 25- or 70-volt outputs, which require special speakers with transformers.
The correct option is to use either an impedance matching speaker selector using the protection enabled, or use impedance matching in wall volume controls. Notice the underline inside sentence above. This is because most speaker selectors are designed with a dangerous feature: submit, directly in front, to disable the safety. If the switch was at back to prevent accidental deactivation with the speaker protection it could be much better. If the safety is accidentally powered down while running multiple pairs of speakers the amplifier will turn off, may blow output fuses, and also well damages the output stage in the amplifier. There are really only 2 good reasons to turn this pull the plug on, essentially the most relevant being that impedance matching volume controls are used on ALL pairs of speakers. The other reason can be if only one two of speakers are run, making impedance matching unnecessary. In this event, though, leaving the security switched in can make only a really small difference to your sound, consider leave it on?
Remember it by doing this: only put one speaker per couple of terminals (usually red and black) within the amplifier. Do not try make use of a surround amp to secure several rooms with one room for the center, one room about the rear surrounds etc. This is due towards the way a surround receiver distributes the sound since you may end up with merely the voice within a room and merely the music in another! The correct hookup to get a surround receiver puts surround sound inside the main room and sound through the left and right main speakers is distributed. My recommendation for linking a surround receiver is really as follows. Run the speaker selector in the front left and front right outputs around the amplifier. Hook your front left & right speakers to your first speaker switch around the speaker selector. You will need to re-balance your surround system by running the pink noise test since the speaker selector will limit the output to the everywhere you look speakers using a small amount. This allows running the leading speakers & one other speakers connected to your speaker selector that don’t have them set being louder as opposed to runners. If your speaker selector has volume controls, you must make sure when using your surround system for movies the actual control reaches the same setting it absolutely was when doing the pink noise test. You may hook the speaker selector towards the ‘b’ speaker switch for the amplifier if speaker volume balance between main left & right speakers along with the rest in the speakers just isn’t an issue.
Another variation is amplifiers that has a direct speaker output for zone 2, 3, etc. These are created drive 1 two of speakers and must be taken with impedance matching if more pairs are to supply. The zone outputs allow another (or third etc.) source, as an example CD in a room and radio in another.
An impedance matching speaker selector provides multiple outputs from input and protects your amplifier from damage. Speaker selectors include 4-12 outputs. As long as your amp has enough power, you may push as many teams of speakers as you desire. Simply connect the speaker selector for an ‘A’ (or ‘B’) outputs plus the rest of your speakers for the speaker selector. You can acquire speaker pickers with volume panels for each separate speaker. Another option is within wall impedance matching volume controls, which require no speaker selector. Most of these are set with jumpers at install time, supplying the correct matching. If you want to operate more pairs of speakers compared to speaker selectors or volume controls are produced for (usually 12 pairs max. depending about the hardware) it is likely you want an extra amplifier to operate the second list of volume controls (or speaker selector) from.
The music signal for your speakers is named alternating current (or AC), given it varies polarity and voltage. This is at comparison to an assortment, as an example which makes a steady, or household power. You may picture current as being the amount of water flowing within a pipe (the wire) and voltage as being the water pressure. Alternating current may be imagined as being a flow that reverses direction and household power as a steady flow a single direction. The analogy just isn’t exact but is close enough to obtain a picture of what on earth is happening. Standard house current inside US reverses direction (polarity) with an interval (or frequency) of 60 times per second, measures as 60 Hz (Hertz).
