How to increase the power of headphones

Not always the purchase of expensive headphones promises to receive a loud and high-quality sound. To cope with this situation will help a special power amplifier, designed for headphones. We will understand what it is and how it works.

Principle of operation

By the principle of his work, he is no different from other power amplifiers. Connecting headphones through a special amplifier, using a regulator, you can change the voltage level of the device and, as a result, the output power.

It is necessary to distinguish between a stationary Hi-Fi device and a portable amplifier. As a rule, headphone amplifiers are quite compact in size, which allows them to be used with the phone outdoors. This device is powered by a removable battery. Stationary Hi—Fi appliances They are distinguished by the fact that the power consumption in them depends only on the level of current consumed from the outlet, while the power consumption portable amps will depend on the volume of the load, and the voltage you set.

According to the laws of physics, the current consumption is directly proportional to the voltage of the current and inversely proportional to the voltage supplied to this source. Therefore, the greater the resistance of the headphones, the lower the output current consumption.

Types of amplifiers

Depending on which components are used in the structure, all devices can be divided into 3 types:

• lamp;
• transistor;
• hybrid.

It should be noted that this classification refers exclusively to stationary models intended for use with computer headphones.

Lamp appliances Reinforce the sound quite softly in comparison with other types of equipment. The sound at the output is very warm and comfortable. A kind of atmosphere creates glowing in the dark bulbs. However, this unit is demanding of operating conditions: it must be used in a well-ventilated area in a place inaccessible to children and animals, since the lamps themselves become very hot during operation and can cause severe burns.

Transistor models convert sound to accurate and clear format.They do not have a certain style, so they are easily suitable for working with any kind of audio material. They have a more compact size and consume significantly less energy than other types of amplifiers. Transistor devices work great with low-impedance headphones.

Hybrid devices use two elements at once - a transistor and a lamp. This model is great for low-impedance headphones, where the transistor provides clarity and power, and the lamp - softness. The hybrid model should be chosen exclusively for your type of headphones, since all the fullness and quality of the sound will depend on it.

Selection criteria

Many music lovers are interested in the question: how to choose a device to enhance the power of headphones? Below are a number of basic criteria that you should pay attention to when buying a power amplifier.

1. Personal sensation. The amplifier should create a feeling of complete immersion in the atmosphere of a musical work. Whether soft or precise, even sound, you should feel a deep satisfaction from listening to your favorite song.
2. Right choice type of amplifier. Depending on your preferences, you should give preference to one of the three types of devices. About the characteristics of the gain of each species was described above. For better sound, it is recommended to select the amplifier depending on the model and technical characteristics of the headphones themselves.
3. Number of headphone jacks. If you are planning on listening to audio materials together, you need to pay attention to this criterion. Some models have the ability to work not with one, but with two or three pairs of headphones. They want such models and are more expensive, the feeling of joint "goosebumps" will fully pay for additional investments.
   
4. D / A converter USB. The presence of a digital-to-analog converter (DAC) in the design of the amplifier allows you to feel the old songs in a completely new form. This criterion is important if the bulk of audio material is heard by you from a personal computer.
5. Number of connection options. Many models allow you to choose the option of connecting the device. If you own both a CD player and a conventional stereo system, the most logical option would be to choose a headphone amplifier that will support each type of connection.If your stereo equipment has a modern RCA connection, it is better to purchase an amplifier with this type of switching.
