Creating the perfect 5.1 and 7.1 configuration
Of course, it’s great to spend a lot of money on a complete home theater speaker system and the amplifier that makes it work together, but that’s just the beginning. Although many people take cabling for granted or consider it only as a necessary after-thought, the way people connect things makes all the difference in the final sound of their home theater systems.

Surround speaker cables allow acoustic signals to pass from amplifiers to speakers in a standard home theater configuration. Although relatively simple, the specific properties of the wire in question affect various sound quality factors, such as noise, fidelity and attenuation, or signal reduction. Although the majority of speaker wiring conductors are formed of stranded copper wire or a similar low-resistance alternative, no conductor is ideal; all metals have some resistance per unit length and per section. The resistance of a given conductor is directly related to the loss of energy that a transmitted signal will undergo during its course. In short, longer and thinner cables generally result in greater attenuation.
Resistance, impedance, frequency
Resistance is not the only factor of concern when adapting cabling to a home theater system. Most modern speaker cables are made in pairs; each cable length contains two conductors that connect the positive and negative input terminals of a loudspeaker to a corresponding pair of an amplifier. These cables are separated by an insulation that prevents the passage of the signal from a path to its partner. Unfortunately, this arrangement also forms a capacitor that adds to the impedance as a function of wire frequency, or resistance. The fact that the audio signals include alternating currents naturally attenuated by the inductance of a wire, another form of frequency-based impedance, also contributes to the resistance.
Choosing the right wiring equipment
Does this seem to be a multitude of factors to follow? Fortunately, most loudspeaker cable manufacturers publish detailed statistics about their products and most home theater components are close enough to each other so that short gaps do not make an audible difference in signal strength. Home theater amplifiers are generally designed to support specific loads, expressed in ohms (Ω). In addition to ensuring that the speaker’s load corresponds to the value specified by the amplifier, many audiophiles try to choose cables whose total resistance is less than 5% of the same number. For example, a 5.1 home theater setup with an 8 Ω loudspeaker should be connected using a wire whose resistance is less than 0.4 Ω.
Length of the cable
Some audiophiles also recommend that cables never exceed 15 m (50 ft.) In a standard home theater setup. Although this limit depends on the dynamics of the space in question, longer cables often tend to serve as radio antennas that can pick up random interference. Electromagnetic interference is further exacerbated when long sections of wire are wound. Resist the temptation of simply making curls to eliminate excess yarn; Instead, measure the distances between the home theater components as accurately as possible and cut or buy the corresponding wire.
Wiring arrangements for the ideal home theater
There are other important factors to consider when creating a home theater setup. On the one hand, the speaker wire is not designed for high stress situations; if caught in something like a passer-by or a pet and stretches hard, it is not likely to break immediately, but such interactions can cause tiny tears in the internal wire strands that ultimately reduce the quality of the sound. Similarly, the compression forces on the speaker cables can disrupt the conduction lines and affect the sound of a particular 5.1 home theater configuration. For added security, always route speaker cables along secure paths, such as walls and ceilings. Use secure hooks, fasteners, and cable management systems to keep cables away and prevent passive stresses, such as the weight of the wire itself, from pulling on the terminals of the amplifier and speaker connectors. speakers.
Use the right speaker cables
If a 5.1 home theater setup or setup does not work because the speakers are too far apart, it is always possible to choose a thicker wire that can support transmission over a longer distance without altering the signal. Remember, however, that the AWG (American Wire Gauge) and SWG (Standard Wire Gauge) gauge numbers found on most speaker cables become smaller as their thickness increases.
You do not have to buy expensive cables to connect the cables of these surround speakers, but you should not think that there is enough 24-gauge cable to allow your AV receiver to spread up to 50 feet long. Each cable has inherent resistance. Since we are talking about resistance to the flow of electricity, we feel a little behind. The finer the cable, the more resistance the cable will have. There are other factors as well, but it’s the most important. The more resistance a cable has, the more it will affect the frequency response, which is possible at the end of the cable run. The reason is that the load of the amplifier when driving a pair of speakers changes with the frequency. So, if you increase the resistance with too thin cables, you can actually change the sound, especially at higher frequencies.
In general, when you connect a home theater system, a 16-gauge cable will work in almost any situation in a room. However, if your course lasts more than 40 to 50 feet, the 12 gauge wire will continue to fall. your resistance and prevent your cables from becoming equalizers for your sound. If you use cables beyond 15 meters, it may be wise to rethink the design of your multizone audio system.
The stakeholder phase counts!
Speakers and shelves must be connected in phase. This means that the positive lead of the AV receiver or amplifier is finally connected to the positive speaker wire and so on with the negative cables or terminals. Once connected correctly, the sound of each speaker is “additive” and everything is fine: the sound is what you expect from a stereo recording or multichannel. However, if only one speaker is wired upside down (positive connection to a negative terminal, etc.), your system has become subtractive. A subtractive system has little effect on wider stereo sounds, but these sounds in the center may disappear. This may sound a lot like the sound coming from your head or the bass can simply disappear. These two indicators are excellent signs of the possibility of crossing a wire. For inaccessible speakers, a 9V battery can be used to test the phase. Just touch the speaker cable briefly to access the battery and watch the speaker (you may need help).
In some cases, it may be necessary to cut sections of wire to match a particular home theater configuration. With conventional matched cables, this is relatively simple because these cables are devoid of outer sheaths; the stripped end of a cable can be inserted directly into a terminal. In contrast, modern 5.1 home theater configurations often have special connectors. When creating a custom length cable with a connector, always use a suitable crimping tool to attach the connector to a freshly cut end. This simple step ensures that the connections are physically stable enough to withstand over-voltages and static electricity induced by incoherent contact surfaces or random movements. Crimping also limits the amount of atmospheric exposure to which bare wires are exposed, thereby reducing oxidation that could increase signal attenuation.
The heat rises to the top!
If you use a rack or shelves for your audio-visual equipment, be sure to place the amplifier or home theater receiver on top, if possible. The heat goes up and you do not want the amplifier to be at the bottom, which will help to cook all the other components and make the ventilation more difficult. It may seem counter-intuitive to have it in mind, but it is a better choice in the long run. If you store your home theater equipment in a cabinet, make sure the ventilation is adequate. An amplifier generates a lot of heat. If you keep this heat in a confined space, you will eventually cook the components and the amp will break down. Give your audio-visual equipment a lot of ventilation or consider adding a fan to your rack or furniture to promote air circulation.
Get the best surround sound
Consider all of the tips above to wire a 7.1 or 5.1 home theater configuration, but remember that these systems are a little more complicated than the usual price. In order to reproduce frequencies in designated ranges, surround sound components usually have specialized features. It may be prudent or necessary to choose different types of wire for individual speakers. When you have to route multiple sections of wire along the same path or path, it may be helpful to work with shielded cables. Antenna interference effects are particularly important at close range and a signal path can cause cross-distortion or poor feedback on another nearby. Also, try not to twist the wires of the speakers together.

Works as always.Although I had some troubles first time when I wanted use it. I had problems when my soundbar was connected to my TV via ARC and I was trying to use a laptop as a source. I could either get the video on my TV without sound from the TV or the sound bar, or I could get the sound of my soundbar without video. This solved my problem. Now my TV is connected to my soundbar via ARC, which comes in every time I connect to the Netflix cable or app on my TV and the optical cable goes off when I connect my laptop to the TV . I receive the video on the TV and the sound in the soundbar without loss of data.
