In every sound system, cables play a vital role. Usually, sound systems have two types of wire RCA and XLR. Both cable’s functions and output quality depend upon the connecting device.

In some cases, XLR quality is best, and sometimes RCA gives you desired quality. XLR cables give the best and balanced quality of signals as compared to RCA cables.

Moreover, XLR has balanced pines that are hot, cold, and grounded cable. RCA has only one unbalanced cable. The balanced cables XLR can give you the best quality of signals over long distances without skipping any types of signals.

The XLR cables can receive strong and low frequencies. They are mostly used in a studio where the frequency of the signal is not defined. Over a considerable distance, RCA does not function.

It can not bear the strong signal due to its unbalanced design. Moreover, XRL can handle noise in a better way as compare to RCA cables.

The hot and cold pines of XRL cables received the signals and handling Noise. Both cables use the reverse method to give you the best quality of sound. If your system has both, then the XLR is the best option.

Some people consider that the cable quality does not affect the sound quality. It is a myth do not consider this it will just create confusion.

How to Connect Multiple Speakers to a Receiver

Suppose you like to enjoy music at home. But you do not have a budget to buy expensive speakers. You can connect your old multiple speakers to get extra sound.

With the single-use of the receiver, you can get rid of the bundle of wires. Moreover, you can control the bass, volume of multiple speakers with a single button.

The connectivity of speakers with the receiver depends upon their impedance. If lower impedance ranges from the receiver, use the parallel connecting method.

The impedance is mentioned on all devices. Every type of speaker has a different level. impedance and sensitivity. Different level of impedance and sensitivity shows that they required different levels of powers.

If the impedance range more than the receiver, you will follow the series method. Connect left the negative terminal with amplifiers positive terminals.

Connect the left wire of speakers with a left jack of amplifiers. Further steps are briefly described below.

  • Take the two wires first one is connected with the speaker’s input, and the second one is connected with the receiver’s output jack. On both devices, mention left, right/positive, negative terminal. So carefully connect it.
