Comparison TOTO TPS-05-FM vs TOTO TPS-02

The maximum size of the memory card that can be used in the player. This parameter is directly related to the card type (see above): each type has its own volume limits. At the same time, the ability to work with capacious media is limited not only by the type of card, but also by the player's hardware. Therefore, many models have a lower capacity limit than the memory card suggests — for example, 128 GB in a model that supports the SDXC format (the theoretical maximum for which is 2 TB).

Note that the reverse situation also occurs — for example, when a device with a maximum capacity of 16 GB only supports microSD cards (theoretical maximum is 4 GB). This usually means that the player can work with newer formats (in our example, at least microSDHC), but for some reason this point is not mentioned in the official specifications (for example, the manufacturer could make a mistake in the documentation).

- CUE support. The player's ability to recognize and use .cue files. Initially, such files were used as lists of tracks on an Audio CD; the sequence of tracks, their duration and name were recorded in them; Nowadays, .cue files often accompany albums and collections recorded on the principle of “all tracks in a row in one audio file.” If the player supports CUE, then you can listen to such an audio file on it as a set of separate tracks, switching between them at will - the player will take data from the .cue file about the starting point of each track and automatically skip playback. In other words, the listening format will be the same as when playing music in the “one file per track” format.

— Lossless formats. The player supports audio formats that use lossless compression. Unlike lossy compression (including MP3), with this compression the sound is not cut down, all its details are preserved as much as possible. Nowadays, there are several lossless formats, the most popular are FLAC and APE (see “Supports audio formats”); The specific set of standards with which the player is compatible should be clarified separately. However, in any case, this function will be useful to those who value the most complete and reliable sound. It is worth considering two nuances. Firstly, lossless files are quite large - one album can ta...ke up several hundred megabytes. Secondly, in order to fully appreciate such sound, you will need high-quality headphones, and ideally a Hi-Fi player (see “Type”).

— Formats without compression (uncompressed). The player supports audio formats that do not require data compression. Most of these standards are professional; they provide very high quality and reliability of sound, but they also take up a lot of space. Examples of uncompressed formats include DSD and DXD (see “Supports Audio”).

— Work in DAC mode. The ability of the player to operate in digital-to-analog converter (DAC) mode - when the device receives a digital audio signal from an external source (usually a computer USB port) and outputs analog audio. This function is found mainly in Hi-Fi models (see “Type”). It will be useful primarily when outputting sound from PCs, laptops or portable gadgets: the native sound cards in such models are often quite “weak”, and when using an external DAC you can achieve much better sound quality.

— Equalizer. This function allows you to adjust the sound volume of individual frequency bands, thus changing the overall color of the sound. Equalizers in modern players can have a different number of bands - from 2 (low and high frequencies) in the simplest models to 8 - 10 in advanced ones. In any case, such a setting can be useful both for adjusting the sound to your own preferences, and for compensating for the shortcomings of connected headphones or speakers - if they “fail” certain frequency bands. In addition, many players have a set of equalizer presets (presets), usually designed for different styles of music - “Classical”, “Rock”, “Pop”, etc.

- FM receiver. Built-in tuner for receiving radio broadcasts in the FM range. It is this range that the vast majority of modern music radio stations use, since it allows broadcasting sound in stereo format. However, some player models also support other standards - for example, AM, in which talk stations are widely represented. To listen to the radio, you usually need to connect headphones - their wire acts as an antenna.

— Recording from an FM receiver. Possibility of recording radio programs received by the player’s own tuner (see above). This function is useful if you want to “save for history” some event from the broadcast - an interesting talk show, a live performance of your favorite band in the radio station’s studio, a live call, etc.

- Dictaphone. The player can operate in voice recorder mode to record sound. Typically, the built-in microphone is used. The general functionality of such a recording is noticeably more modest than in specialized voice recorders, but for simple tasks it may well be useful.

— Built-in speaker. Its own built-in speaker allows you to listen to music without connecting headphones or speakers. In some situations - for example, when watching a movie together from the player screen - this function can be very useful. However, it is worth considering that the capabilities of the built-in speaker are usually quite modest; as a result, the volume and sound quality are low.

- Digital camera. Your own digital camera that allows you to use the player to take photos and videos. The quality of filming in most cases is not high, but there are exceptions - some player models are not inferior to middle-class smartphones in this indicator. In addition, the cameras in this case are intended not so much for highly artistic filming, but for “capturing the moment.” It is also worth noting that the location of the camera may vary. Most often it is installed on the back side, but there are also players with front cameras that allow you to take selfies and use video calling. And the most advanced players (usually models with OS, see above) may have a pair of cameras - main and front.

— micro-Jack (2.5 mm). The micro-Jack connector belongs to the category of TRS connections (Tip, Ring, Sleeve). The 2.5mm plug is the smallest diameter TRS plug. Micro-Jack connection (2.5 mm) is typical for mobile devices and compact portable audio equipment. The connector is backwards compatible with mini-Jack (3.5 mm) and Jack (6.35 mm), but for this you must use the appropriate adapters. Of course, when using adapters, note that the presence of an additional connection reduces the overall quality of the audio signal. To prevent degradation in quality, some MP3 players are equipped with a micro-Jack output in parallel with the mini-Jack or Jack.

— mini-Jack (3.5 mm). The mini-Jack (3.5 mm) connection is the most common type of TRS (Tip, Ring, Sleeve) interface. The mini-Jack output is found on the vast majority of consumer-grade MP3 players. The mini-Jack connector has a 3.5 mm plug — this is the middle (intermediate) type of TRS connections. The mini-Jack output is capable of transmitting an audio signal of sufficiently high quality. The mini-Jack connection is ready to satisfy the needs of both beginners and advanced music lovers.

— Pentaconn (4.4 mm). Pentaconn connection — 5-pin balanced output. Thanks to this connection, you can connect powerful amplifiers or DACs to your MP3 player. Additionally, the connector is also suitabl...e for connecting good high-impedance headphones. Pentaconn uses a larger than the mini-Jack plug, its diameter is 4.4 mm, it is stronger and more reliable than the 3.5 mm connection. The Pentaconn's balanced connection makes it possible to handle higher power audio signals. Thanks to this connection, it is possible to transmit a signal over a fairly long distance.

— Coaxial. The coaxial connection (S/PDIF) enables the transmission of an enhanced audio signal. In the coaxial signal algorithm, there is no digital to analogue conversion stage, which has a positive effect on the quality characteristics of the sound. RCA or TOSLINK connectors can be used for coaxial connection. Coaxial output is found mainly in Hi-End MP3 players. This is an expensive technique that requires the use of fairly expensive accessories. But in return, these players provide high-quality sound, designed for professional musicians and advanced music lovers.

— Optical. The optical connection is represented by a TOSLINK connector and a fibre optic cable. The essence of the optical connection is that the audio signal is converted from electrical to optical. At the other end of the cable, the optics are transformed back into digital sound. Being in optical form, the signal ceases to be subjected to interference and other interference. The optical signal does not lose its original quality even when transmitted over long distances. MP3 players with optical output provide the ability to listen to audio in high quality. The vast majority of MP3 players with a TOSLINK connector are premium models that can satisfy the needs of musicians, music lovers and advanced audiophiles.

Characteristics of the display installed in the player.

— Color(color/monochrome). The display color is selected by the manufacturer taking into account the functionality of the player. So, for a device that supports video and graphic materials (see “Other formats”), a color display is mandatory, and if the player only works with audio, a monochrome (one-color) screen is quite sufficient for it, especially since such screens are cheaper and consume less energy.

- Size. The diagonal dimensions of the display is directly related to the type of device (see above). Thus, classic audio players do not require large screens, in most of them this figure does not exceed 1.5"; but for a media player, 1.5" is, in fact, the absolute minimum, usually the diagonal is 3" or more. Also large Hi-Fi players are equipped with screens, they also provide a similar feature for the convenience of working with special tools.In general, a large screen, on the one hand, is convenient to use, on the other hand, it affects the dimensions and price of the device.

— Display resolution. Display dimensions in pixels vertically and horizontally. With the same diagonal, a higher resolution provides a clearer and more detailed image, but increases the cost of the player. In addition, not every player needs high detail: if the screen is used only for service information like the title of a so...ng, you can get by with small resolutions. Therefore, you should pay attention to this parameter only when it comes to a media player (see “Type”) on which you plan to often watch videos. In other cases, we can assume that the screen resolution is guaranteed to be sufficient for the tasks for which the device is intended.

— Sensor type. The type of matrix used in the screen.

• OLED. An OLED matrix in which each pixel is actually a separate LED. In portable players, most of these screens are monochrome; for color displays it is more convenient to use other technologies.
• TFT. General name for liquid crystal displays. In this case, the TFT designation is used mainly for relatively simple screens that do not use advanced technologies like the IPS described below and have rather limited characteristics. However, such screens can be made in color and have high resolution.
• AMOLED. A development of the OLED technology described above, designed to create high-quality color displays. AMOLED screens are characterized by high brightness, rich colors and good viewing angles. Among their disadvantages, we can note a slightly shorter service life than the same IPS, as well as a tendency to fade in areas where bright parts of the image are often displayed.
• IPS. One of the most popular color screen technologies used in modern portable technology. Provides good color rendering quality and wide viewing angles; The picture quality is somewhat inferior to AMOLED, but is cheaper and lasts longer.

- Touch screen. The touch screen is similar to tech used in modern smartphones. On-screen controls are often more convenient and versatile than using buttons and other hardware controls. For normal use, such a display must be quite large. We also note that a touch screen is mandatory for models with a full OS (see above).

The type of connector used to charge the player’s built-in battery, or more precisely, to connect an external charger. The role of such a device can be played by a network or car adapter, a power bank, or even a USB port of a PC or laptop. As for specific connectors, the most common options are:

- microUSB. A smaller version of the USB connector designed for portable devices. It appeared quite a long time ago, but does not lose popularity in our time and is used by many manufacturers.

- MiniUSB. Similar to the connector described above, which differs only in the size and shape of the socket - for this interface they are slightly larger than for microUSB. Because of this, the connector is less common.

- USB C. A miniature USB connector, positioned, among other things, as a potential successor to microUSB. Unlike its predecessor, it has a double-sided design, thanks to which the plug can be inserted into the socket on either side.

— Lightning. Apple branded connector. Like USB C, it has a reversible design, while being somewhat more convenient and reliable, but the use of Lightning is limited to products from Apple itself.

- Branded. A connection connector that does not belong to generally accepted standards and is used to a limited extent - in equipment from one or several manufacturers. However, due to general standardization, this option has practical...ly disappeared from the scene.
