How to connect speakers to TV via optical audio output

Not everyone can afford to go to the cinema, and not everyone needs it. Therefore, many people watch movies at home, on TV, but the power of the built-in speakers is not enough, so you have to connect speakers. This begs the question, how to do it? There are many different ways, one of which is an optical cable.

What is an optical cable for connecting acoustics

An optical cable generates a digital audio signal and transmits it. The cable amplifies the TV signal, thereby making it louder, and then transmits it so that we can hear it. You can use coaxial cable, but optical has more advantages. For example: it reduces signal loss, it also behaves much better over long distances.

How to connect an optical cable to a TV and to a speaker system – instructions

Turn off your TV before connecting!

To connect acoustics using an optical cable, you can use this instruction:

1. First, find on the back or side of the TV a connector with one of the following inscriptions (different TVs have different names): Optical Audio, Digital Audio, Toslink. Then connect the first end of the cable.

Important! The recommended wire length should be no more than 5 meters, then the sound will be transmitted without interference and its loss will be excluded.

The optical cable to connect the speakers to the TV should be no longer than 3-5 meters

2. Locate the Digital Audio IN jack on your speaker device, then plug in the other end of the cable.
3. Specify the source of your choice, the default is D.IN. Then go to the settings section on the TV, select the “sound”, “speaker settings”, “select speaker” section. Select “external receiver”, “optical output”.

Connecting additional audio amplifiers

Using an optical cable, you can connect various types of acoustics to your TV. The acoustic system is active and passive.

Computer speakers are an example of active acoustics. Connect active acoustics most often to the headphone jack.

Tips for Buying an Optical Cable

A few tips and tricks to follow before buying an optical cable. After all, all this affects both its durability and the quality of sound reproduction.

1. It is advisable to buy thicker cables, as they are more tenacious.
2. You should not save on the cable, as the more expensive and high-quality ones have a nylon sheath, which provides additional protection.
3. Pay attention to the bandwidth of the cable, the more sound it can pass through, the better. Good cables pass from 9 to 11 MHz.
4. It is also advisable to buy cables with a glass core, as they are of better quality than plastic ones.

Optical output on TV

To improve the sound signal on TVs, a fiberglass cord was developed to transmit light signals over long distances. Thanks to this, the sound is transmitted at the highest level. This is due to the lack of influence of electromagnetic light on the transmitted signal. The transmitters are LEDs, and the receiver is a photodetector with an amplifier that restores the distorted signal.

What is it used for

Use the optical output to broadcast sound from the TV to the speakers. With it, it becomes possible to receive and process an audio signal with acoustics. For this to happen, there must be a special Optical OUT connector. The main task is to provide high-quality sound.

Most light transmission devices support data transmission:

• Use an electrical signal to turn it into an optical one.
• The sound is transmitted unchanged, the only thing is that its volume changes to a stronger one.
• Reception of an optical signal.
• Converting an optical signal into an electrical one.

Important! No matter how good the cable is, it will work at full capacity only with high-quality equipment, then you can load it with various tasks and it will do an excellent job with them.

What is the acoustics for the TV

Over the years, many acoustic devices have been created, each different from the previous one. But despite this set, all systems are divided according to certain parameters:

• Design.
• Purpose of application.
• Active and passive.
• Connection method.

Design

The design is responsible for the sound of the system. The design uses a lot of design solutions related to the shape of the device, but still subdivide 3 forms:

1. Rectangular.
2. Pyramidal.
3. Spherical.

Rectangular speakers produce the best sound quality. The cases are also divided into closed and with a phase inverter. The first type is the most common and can be seen on most speakers. The second is used on subwoofers.

Connection variations depending on the type of speakers

There are two types of speakers: wired and wireless. If everything is clear with wireless – connected to bluetooth and control through another device, then things are much more interesting with wired ones. There are a lot of different ways to connect wired speakers. Everything is limited only by the connectors that are present on the speaker and your cords that you have available. A very common way to connect acoustics to an HDMI-optics TV.

How to connect fiber optic to TV

The cable must be routed correctly before connection. The main thing is that it should be 10-15 cm longer than the distance from the TV to the speakers. After you have run the cable, you need to find a special connector, which is usually labeled as: Optical Audio, Optical Digital Audio Out, SPDIF, or Toslink. Connect your cable using this port.
Now let’s take a look at your audio system. Find the same connector on it and plug the cable into it. When all these steps have been done, turn on the TV and your system. If there is a sound, then the connection succeeded.
If there is no sound – check that the volume level on the TV and on the speakers is not equal to 0.

Prices for high-quality optical cables

The approximate cost for a cable of certain characteristics, we will also compare different models and select the most suitable one. It is important to remember that the cable selection criteria discussed earlier should be used. Popular Models:

1. Subscriber optical cable Alpha Mile FTTx , which consists of a steel core and consists of fiberglass. Designed for laying attics, basements, it is also possible to lay between houses. For its mineral fiber dimensions, it is quite resistant to mechanical damage and deformation. It has a rounded shape, due to which friction is almost completely eliminated when laying it. A similar cable will cost about 6.500-7.500 rubles per kilometer. In short unwindings, it is used to connect home acoustics and TV.
2. Optical cable SNR-FOCA-UT1-04, for combining communication lines between buildings. The cable is equipped with a central optical module that contains the fibers. Hydrophobic gel inside – protects the fiber from hydrogen. It will cost about 18,000-20,500 rubles per kilometer.
