Integrating Desono™ loudspeakers and AMP-450BP backpack amplifiers

Speaker wires serve as the electrical connection between audio amplifiers and loudspeakers. They are used to transmit sound signals from audio amplifiers to speakers. Like the normal wires that we are used to in our everyday lives, are speaker wires dangerous as well?

Can speaker wires shock you? Most people cannot tell with certainty the true extent of electrical hazards posed by speaker wires. Speaker wires cannot shock you. The amount of current that passes through speaker wires is very low and not strong enough to cause an electric shock to humans beings.

There is voltage in speaker wires. Any medium that carries or transports electricity has some amount of voltage inside it. In speaker wires, the amount of voltage that runs through them is dependent on the amplifier power. Speaker wires carry whatever level of voltage that comes out of the amplifier they are connected to.

For a watt amplifier that is driving an 8 Ohm speaker, the voltage that will be transmitted through the speaker wires would be about 30 volts. This voltage is entirely dependent on the power rating of the amplifier. This means an amplifier with a higher power rating will drive a relatively high voltage through the speaker wires connected to it. So yes, a speaker wire connected to a powered amplifier has some voltage running through it.

With speaker wires, the voltages involved are very low. This voltage is usually quite small that most people would not feel it. Thus, electric shock is rare from appliances and wires with low voltages passing through them. Speaker wires are not plugged into a wall socket or an extension socket. Due to this, they do not carry the same high level of current as normal power cords.

Generally, audio signals that run through speaker wires are not strong enough to be dangerous when touched. However, this is not enough reason to be complacent when handling speaker wires. Speaker wires are made of two stranded wires, usually made of copper. These copper wires are heavily insulated by plastic such as PVC, and as such, as long as the currents stay inside the wires, it poses no danger to people.

With electricity being confined within the speaker wires at all times, there is little risk of electrocution. With that being said, due to the low current that passes through speaker wires, even when the naked speaker wires come in contact with the human body, it will not pose any harm.

There is a belief that, whenever wires and human beings come together, there is always the potential for injury or harm to occur. This potential for injury can be from trailing wires or electrical shock. In the case of speaker wires, this danger results from trailing wires and no risk of electrical shock.

Trailing wires is one of the most prevalent causes of accidents and injuries in workplaces and homes. It is very easy to catch your foot on stray wires. This can cause you to stumble forward and possibly injure yourself on a nearby surface or object. As a result of this, there is the need to ensure that speaker wires are not left lying about loosely. Due to the potential injury that trailing speaker wires can cause, it is not advisable to run speaker wires across walkways and doorways.

Sometimes, speaker wires pose a danger to other musical equipment. Speaker wires can cause damage to the appliances they are connected to. This means speaker wires can cause harm to the speakers and amplifiers they are connected to.

If speaker wires are not handled properly, they can cause damage to amplifiers by causing them to blow out. Bad wiring and broken speaker wires can also cause intermittent signals and transients that can damage your speakers.

Transients are sudden bursts of energy that can be caused by abruptly powering off of your speakers. This damage can occur when speakers are very hot. A Speaker wire is basically like any other wire out there. As I mentioned earlier, it consists of two small wires — positive and negative wire. Usually, the positive wire is red, and the negative wire is black. However, most speaker wires are not colored. Like every wire out there, current flows from positive to negative. Hence, as long as the speaker wire is connected to a powered amplifier, there will be a current flow through the speaker wire.

Current always flows from the positive side to negative the negative side of a circuit. When these two wires touch, it leads to the short-circuiting of the source supplying current to these wires. This source is usually the amplifier.

Therefore, when speaker wires touch, this results in shorting out of the amplifier. This causes the side of the amplifier channel where the speaker wire is connected to die out. It is very important to take safety precautions when working with speaker wires. Due to some of the risks and dangers that surround the use of speaker wires, safety must not be compromised when handling wires in general.

Adhering to these practices will protect not only your speaker wires but your amplifiers and speakers as well. One of the major reasons why wires, in general, pose a risk is that the danger they pose might not be immediately visible.

A wire might appear to be in good working condition but actually have a small cut or fray that might not be easily seen. Inspecting your speaker wires regularly will help you see if they are looking good and have no frays, damaged or broken parts. Regular inspections will also help you to identify if the speaker wires are securely connected to the amplifiers and speaker connectors. It is worth noting that one of the most important measures to ensure no damage to amplifiers and speakers is good speaker wire connections.

This is why it is very necessary to have regular checks and thorough inspection of speaker wires. Wires can be very costly, especially when they are very long. Keeping them in good condition will help ensure that they will be available and fit for use when needed. It is not advisable to coil speaker wires too tightly. Coiling them too tightly can cause unseen damage to the wires inside the sheath.

Speaker wires can be bundled loosely and stored in a safe place until they are needed. Diagnosing problems with musical setups can be a troublesome task. This can partly be attributed to the various components and equipment that form an audio system. However, there is a simple way to check if your speaker wire is faulty or not. To do this, you have to first disconnect the speaker wires from the amplifier.

The speaker wires should still be connected to a working speaker. At this stage, you would need to get a common household battery such as an AA, AAA, or a 9-volt battery. This will be used to test the speaker wires to see if they are working properly. All batteries, speakers, and speaker wires demonstrate negative and positive polarity.

To perform the test, you have to pick up a speaker wire and hold one of its ends to one battery terminal. This terminal can either be the positive or negative terminal. Now you need to take the other wire end and repeatedly touch and disconnect it from the remaining battery terminal. However, this should be done for a brief moment in a gentle brushing motion.

Doing this for a long period may damage the speaker and the speaker wires. The following video gives a good summary of how to check if your speaker wire is working properly, using a 1. Speaker wires are very important.

They are used to connect speakers, amplifiers, and other audio components. Without them, speakers will not be able to function. Table of Contents.

Choosing the right speaker wire

Figuring out the best speaker wires can be a daunting task, especially for first time installers. You need to consider the proper gauge that will deliver the best sound quality, how long of cabling you need, which type of cable you need, and what type of connectors are required by your speakers. Before we can discuss what gauge wire is appropriate for your speakers, you first need to understand what wire gauge even is. The lower this number is, the thicker the wire is. So, what does the thickness of the cabling matter for speakers?

Do you choose un-shielded cabling or pay the small premium for shielded cabling? Is shielding worth the added cost to your project? Are there any downsides to using shielded speaker cable? Speaker cables maintain a high signal to noise ratio SNR because their load impedance is low usually 4 to 8 Ohms and their current high. Any noise coupled onto the speaker wires will have current a magnitude of order less, such that it can be considered irrelevant for normal listening.

How to wire Four Speakers to One Amplifier

One of the main challenges of setting up any permanent sound system is wiring it, and this is especially true for outdoor speakers — special consideration needs to be taken to make sure that everything is properly weatherproof. Wiring a sound system is something that you want to do once, and do right. If not? Best case scenario you have to re-run wire, which can be a particular pain with outdoor runs. Worst case scenario?
