IV. INSTRUCTIONS FOR USE

Power on and setup

The inclusion of a column after purchase in a store is carried out by a specialist with the appropriate qualifications.

Before plugging in:

a) make sure that the speaker power supply switch is set according to the voltage in your apartment.

b) check the presence of mains fuses in the Fuse holder block.

Remember that with a supply voltage of 127 V, fuses of the PM 2.0a type should be used. The use of other fuses is not allowed;

c) set the volume control knobs to the initial position (to the left);

d) connect the existing sound signal sensor (ZVS, electromusical instrument "Yunost" tape recorder) to input 1 using a shielded connecting cable. Turn on the horn sensor;

e) Plug the power cord into a power outlet.

The column is turned on by pressing the key with the designation "network" all the way, from the side of the rear wall, while the control lamp should light up.

Set the volume control 3 for inputs 1, 2 to the desired volume, knobs I, 2 - the desired tone of sound.

When connected to input 3, the volume is controlled by knob 4, and knob 3 to the leftmost position.

Note. Input 2 can be used to connect small portable transistor radios to enhance the sound.

Input 3 can be used to connect an electric guitar, as well as other sources with an output voltage of at least 5 mV.

Do not leave the switched on column unattended for a long time!

V. WARRANTY AND QUALITY CLAIMS

The manufacturer guarantees the normal operation of the column for 12 months from the date of its purchase in the store.

The date of purchase must be noted in the dispenser passport and warranty card. In the absence of a mark of the trading organization in the passport and warranty card, the period is calculated from the date of issue of the dispenser by the factory.

When malfunctioning column owner has the right to free repair during the warranty period. After the repair, the warranty card remains in the workshop.

If during the warranty period the column fails due to the fault of the owner due to improper operation or non-compliance with the instructions given in the instructions, then the repair is made at the expense of the owner.

Perhaps the main role in resolving this issue will be played by the choice of amplifier.
Function
The amplifier is responsible for the quality and power of sound reproduction. At the same time, when buying, you should pay attention to the following designations, which mark the introduction of high technologies in the production of audio equipment:

• Hi fi. Provides maximum purity and accuracy of sound, freeing it from extraneous noise and distortion.
• Hi end. The choice of a perfectionist who is ready to pay a lot for the pleasure of distinguishing the smallest nuances of his favorite musical compositions. Often hand-assembled equipment falls into this category.

Specifications to pay attention to:

• input and output power. The nominal value of the output power is decisive, since edge values ​​are often unreliable.
• Frequency range. Varies from 20 to 20000 Hz.
• The coefficient of non-linear distortion. It's simple - the smaller the better. The ideal value, according to experts, is 0.1%.
• Signal-to-noise ratio. Modern technology assumes a value of this indicator in excess of 100 dB, which minimizes extraneous noise when listening.
• dumping factor. Reflects the output impedance of the amplifier in relation to the nominal load impedance. In other words, a sufficient damping factor (more than 100) reduces the occurrence of unnecessary vibrations in equipment, etc.

It should be remembered: the manufacture of high-quality amplifiers is a laborious and high-tech process, respectively, too low price with worthy characteristics should alert you.

Classification

To understand all the variety of market offers, it is necessary to distinguish the product according to various criteria. Amplifiers can be classified:

• By power. Preliminary - a kind of intermediate link between the sound source and the final power amplifier. The power amplifier, in turn, is responsible for the strength and volume of the signal at the output. Together they form a complete amplifier.

Important: the primary conversion and signal processing takes place precisely in the preamplifiers.

• According to the element base, tube, transistor and integrated PAs are distinguished. The latter arose in order to combine the advantages and minimize the disadvantages of the first two, for example, the sound quality of tube amplifiers and the compactness of transistor ones.
• According to the mode of operation, amplifiers are divided into classes. The main classes are A, B, AB. If class A amplifiers use a lot of power but produce high quality sound, class B is exactly the opposite, class AB seems to be the optimal choice, representing a trade-off between signal quality and enough high efficiency. There are also classes C, D, H and G, which have arisen with the use of digital technologies. There are also single-cycle and push-pull modes of operation of the output stage.
• By the number of channels, amplifiers can be one-, two- and multi-channel. The latter are actively used in home theaters to form the volume and realism of the sound. Most often there are two-channel, respectively, for the right and left audio systems.

Attention: the study of the technical components of the purchase, of course, is necessary, but often the decisive factor is the elementary listening to the equipment according to the principle of sounds or does not sound.

Application

The choice of amplifier is more justified by the purposes for which it is purchased. We list the main areas of use of audio frequency amplifiers:

1. As part of a home audio system. It's obvious that the best choice is a two-channel single-cycle tube in class A, also optimal choice can constitute a three-channel class AB, where one channel is defined for a subwoofer, with a Hi-fi function.
2. For car audio system. The most popular four-channel amplifiers are AB or D class, in accordance with the financial capabilities of the buyer. In cars, the crossover function is also in demand for smooth frequency control, which allows you to cut frequencies in the high or low range as needed.
3. in concert equipment. Higher demands are reasonably placed on the quality and capabilities of professional equipment due to the large distribution space. sound signals, as well as a high need for intensity and duration of use. Thus, it is recommended to purchase an amplifier with a class not lower than D, capable of operating almost at the limit of its power (70-80% of the declared one), preferably in a case made of high-tech materials that protects against negative weather conditions and mechanical influences.
4. in studio equipment. All of the above is true for studio equipment. You can add about the largest frequency reproduction range - from 10 Hz to 100 kHz in comparison with that from 20 Hz to 20 kHz in a domestic amplifier. Also noteworthy is the possibility of separate volume control on different channels.

Thus, in order to enjoy clear and high-quality sound for a long time, it is advisable to study all the variety of offers in advance and choose the option of audio equipment that best suits your needs.
