Downforce

The force of pressing the needle on the plate, which the complete pickup (cartridge) is designed for.

This force depends on the rigidity (compliance) of the needle: the greater the clamping force, the harder the cartridge, respectively, the less pliable it is. It is also believed that less pressing force wears out the record less, but it cannot be said that "light" cartridges are definitely better — there are many other nuances. So in fact, information about the pressing force of a complete pickup is needed mainly in case of its replacement. Usually, the pressing force provided by the arm of the turntable is regulated within these limits, so the new cartridge must also be rated for the same values of downforce — otherwise there is a chance that the turntable will not be able to correctly align.

Pickup weight

The weight of the pickup (cartridge) supplied with the turntable.

The weight of the cartridge determines the characteristics of balancing the tonearm to set the optimal tracking force. However, pickups in set are usually optimally compatible with the corresponding tonearms, so there are no problems with adjusting the turntable. But when buying a replacement cartridge, you should pay attention to this parameter: it is advisable that the new cartridge does not differ too much in weight from the old one, otherwise the tonearm adjustment range may not be enough for the correct balance.

Speed control

A method for switching the disc rotation speed provided in the player.

Manual. This option is only found on belt driven models (see above). It provides the transfer of the belt to another pulley, due to which the gear ratio and, accordingly, the rotation speed change. This method is not as fast and convenient as automatic, however, it allows you to do without unnecessary electronic circuits (many audiophiles appreciate this feature, because additional electronics can interfere and degrade sound quality).

Electronic. Speed switching, carried out by changing the parameters of the electric motor — usually, the user just needs to press a button or move the regulator. This method is much faster and more convenient than mechanical, and for direct drive models (see above) is generally the only possible option. However, the electronics responsible for switching the speed affect the cost of the player and can become a source of additional interference; however, the latter can be compensated by installing control circuits in an external power supply (see below).

Phono stage

A phono corrector is a specially designed preamplifier used when working with vinyl record pickups. Initially, the sound on such records is recorded with distortion of the amplitude-frequency characteristic, namely with an increase in volume from low to high frequencies; this is due to the technical features of the recording process. Accordingly, the phono corrector not only amplifies the signal to a level sufficient for feeding to the power amplifier, but also corrects the amplitude-frequency characteristic, “pulling out” the bass and reducing the volume of the HF. And the built-in phono corrector allows you to connect the player to the power amplifier directly, without using intermediate equipment. True, in terms of characteristics, built-in preamplifiers-correctors are inferior to external ones. Therefore, some models with this function may provide a “bypass” mode, allowing you to pass the signal bypassing the built-in phono corrector to an external, more advanced one. And there are also vinyl players without a phono corrector at all.

Tempo adjustment

The presence in the player of an electronic module that allows you to change the tone of the sound being played, in other words, to make it higher or lower by a certain interval, in other words, change the playback speed. This feature is also known as a "pitch controller".. It is relevant primarily for DJ "turntables", as it allows you to mix tracks recorded in different keys. Some home players also have a tempo control, but its capabilities are much more modest, and a real need for such a function rarely arises.

Frequency range

The range of frequencies that the player is capable of outputting when using a standard pickup.

The wider the frequency range, the more complete the sound picture will be, the less low and/or high frequencies will remain behind the scenes. However, from a practical point of view, it does not make sense to expand the range beyond the values \u200b\u200bof 16 – 22000 Hz — it is within these limits that the human ear hears the sound (and even then not everyone). In high-end audio equipment, including turntables, there are more extensive ranges; however, such characteristics are a kind of “side effect” of high-end technology that manufacturers use for advertising purposes.

In addition, we note that an extensive frequency range is not yet a guarantee of high-quality sound: the sound picture depends on many other parameters, from the amplitude-frequency response to extraneous interference.

Signal to noise ratio

The ratio between the useful signal and extraneous noise at the output of the player. It is also colloquially called "electrical noise" (although this is not entirely true).

The higher this indicator, the quieter the noise (it is impossible to completely eliminate them), the clearer the signal will be. In the case of turntables, the signal-to-noise ratio is considered to be at least 50 dB; and in the most high-end devices it can exceed 90 dB.

Note that this paragraph may additionally indicate the value of mechanical noise. Despite the similarity in name, this is a completely different indicator — it describes the volume of extraneous sounds produced by the motor, drive and other moving parts of the "turntable". Accordingly, for mechanical noise, the lower the decibels, the better. You can estimate its approximate level using special comparative tables.

Knock ratio

The maximum knock factor that the turntable is subject to under normal conditions.

Detonation in this case is called sound distortion associated with short-term periodic irregularities in the rotation of the disk. The lower the detonation coefficient, the lower the level of such distortions; it is believed that for audiophile-class equipment it should not exceed 0.2%, although in more modest models it may be higher.

Note that for different playback speeds, knock coefficients can also be different. Manufacturers in such cases may indicate the minimum value, despite the fact that it can be achieved not at the usual 33 rpm, but at 45 or even 78 rpm. Therefore, when choosing a high-end turntable, it's ok to clarify this point.

Power consumption

Rated power consumed by the player during normal operation.

Modern turntables are very economical: most models, even those equipped with built-in acoustics (see "Features"), the power consumption does not exceed 15 W, and there is no need to talk about any serious impact on congestion in the electrical networks (as well as electricity bills). The exception is some premium-class devices, in which the weight of the platter (see below) reaches several tens of kilograms, and the corresponding engine power is required to rotate such a mass.
