It is visible, that engineers of the company have lead greater work. In comparison
That for today iPod nano provides most qualitative zvu
Certainly, it is not necessary to forget about volume, that in itself quality of an audiopath of a player now it is rare is defining - the greatest notebook cmos battery influence is rendered with headphones. On the other hand, it is all the same pleasant, that a bottleneck nano never irrespective of the fact which from models «ushek» it will be possible will buy.
General results MP Non-uniformity ACHH (from Hz up to kGc), dB: +0.15,-0. Well Noise level, dB:-90. it is very good the Dynamic range, dB: 71. Sredne Harmonious distortions, %: 0.2 it is bad Intermodulyacionny'e distortions + noise, %: 19.2 it is very bad Interosculation of channels, dB:-90. it is excellent Intermodulation on kGc, %: 0.0 it is very good the General estimation: Sredne Position significally spoils at use for the test of a MP3-file. High quantity of distortions and the made narrower dynamic range in any way allow to put to a player a high estimation. It is remarkable, that same problems had and iPod mini, and here constructed on typical element to base (codec notebook cmos battery SigmaTel with the hardware support MR3, used in tens manufacturers) a little allocated from the general of some iPod Shuffle with such files coped easily and easy. In view of it, and also faultless (that show tests with use of not compressed source) is possible for the hardware to approve, that roots of such behaviour are covered somewhere inside firmware players. Even more precisely the module, responsible decoding of MP3-files, apparently, constant still with times the very first iPod (and unnecessary for Shuffle), it is sometimes incorrect working with MP3-files (depending on the codec, parameters of coding and other factors, down to positions of stars on the sky) is guilty.
To owners iPod, using qualitative headphones, or notebook cmos battery connecting a player to acoustic to system which distinguish any discrepancies of reproduction, remains to recommend whenever possible to abstain from uses MP3, using AAC or even WAV PCM (the quantity of memory allows to do it). Certainly, to this advice to follow not so it is simple, in view of that, that a content in MR on orders it is more, than in other formats, however it is far not with all files will arise problems. As a last resort, if degradation of quality will be appreciable on hearing, it is possible the given file will recode in AAS.
The additional opportunities Perhaps, the most interesting additional function in a player - an opportunity of notebook cmos battery viewing of images. Certainly, with polutoradyuymovy'm the display iPod nano not will turn in the media-center, but its qualities quite suffice that this function to consider not far-fetched. iTunes automatically processes images for the corresponding sanction, that allows to store a huge collection, not using at it is a lot of memories - the average size of a photo makes nearby Kb. Simply to count, that the size of a collection from 10 photos hardly probable will be reflected on the remained free space.
Pleases presence of function a slide-show. It it is simple enough it is organized, but has quite adjusted parameters: time of display of each image, reproduced at this time music, repetition of images and their casual choice (shuffle) and even effect at change the staff.
Contacts. First can seem, that search of the necessary record in the big notebook cmos battery list can appear rather uneasy employment - in fact here is not present opportunities to organize search, having chosen any the letter (as in a mobile phone). But in practice use of contacts it appears quite convenient during testings I stored on a player nearby 10 contacts, scrolling of the list borrowed the order 5 seconds (it it is intellectual enough is dispersed), and search of the necessary contact of the order 15 seconds.
On the color screen it is beautiful the calendar current month is looked by color is allocated, and tags near to dates mean presence any the events planned on this day. The player is able to display reminders wake it not can, but at inclusion it is obligatory will inform about forthcoming event.
In a player four games are programmed: Brick, more known as Arkanoid, Music Quiz (in which it is necessary for notebook cmos battery the user to guess a sounding melody from five offered variants for ten seconds - with each second the quantity of prize-winning glasses decreases, but gradually wrong variants disappear), Parachute where you operate a gun, from which it is necessary to shoot enemy helicopters and jumping out therefrom a landing, and also novelty Solitare called, possibly, to go through separation with PC under control of Windows.
There is an opportunity of viewing zametok (short text files which you manually copy in a corresponding folder). But for the Russian user hardly this function will appear actual: besides the size is limited by KB, there are problems with Russian symbols - notebook cmos battery they are displayed in not readable to the coding). However, there are the programs breaking a file on the necessary quantity of pieces and correcting problem with by the coding.
It is useful function of hours nice and changing color depending on time of day hours in addition can be established on different cities;
Screen Lock. Interesting, but hardly probable useful function allows "to cipher" the screen from other people. The display/safe it is very beautiful looks, but it is not a lot of will be the users storing on iPod the valuable information. Confidentiality of contacts, zametok and a calendar to understand, but hardly there will be the people worrying about volume, that someone still is notebook cmos battery possible can hear to their favourite songs.
Display of an illustration of an album. If in iTunes at songs the image of an album (artwork) is added, it automatically will be transferred on a player, and will be displayed to the left of names of a composition. The picture it is enough small, but it is possible to see it in a large kind. To make to constants such method of display not it will turn out. And it is a pity.
At last, someone the classical stop watch can be useful - it is maximal is simple in use and not has any interesting functions.
A feed it is pleasant was surprised with parameters of time of independent work of a player - if in the previous models iPod real an operating time was notebook cmos battery much below declared (in this connection users submitted even a little judicial claims on Apple), iPod nano, on the contrary, works longer, than is specified inofficial technical documentation.
In a mode of reproduction of music (loudness on a level about %, illumination is switched off, any actions above by a player not it was made) iPod nano has worked hours of minutes, that on minutes above a limiting parameter in characteristics In a mode of reproduction a slide-show (change of the staff every second, it is constant the included illumination, simultaneous reproduction of music on a level of loudness about %) time of independent work of a player has made hour of minutes, against four hours in characteristics.
Time full zaryadki from up to has made 1 % of hour of minutes. And again the parameter advances official data: Apple notebook cmos battery informs about hours of time on full zaryadku a player (one and a half hour, as she said, should to finish it up to a level of a 80 percent charge) Pleasantly also, that the charge of the accumulator is displayed is rather exact. In particular, on many mobile phones there is a situation when at exhaustion of half of time of independent work of the device phone showed full or nearly so a full charge, and then this level it is prompt decreased. In iPod nano such lack it has been noticed not, that allows is exact enough to plan time of use of a player. A unique small minus with a feed which it is possible to notebook cmos battery note absence of the information about a level of a charge of the accumulator during most zaryadki. When iPod nano it is connected to active to USB-port, it is necessary to the user to be content with one from two pictograms symbolizing process zaryadki and completely the charged accumulator Management Despite of compactness of a player, Apple not began to endow firm controls Click Wheel. As well as in greater models iPod it is full-function: reacts on movement on its surfaces and it is pressed in the center and on a circle. All management is reduced just to this wheel: unless on a player is ry'chajok hold it is more any buttons on iPod nano is not present, that it is looked notebook cmos battery rather stylishly.
In practice ClickWheel quite it is convenient, any deficiency in controls not it is felt: the touch surface serves for scrollings and volume controls, and pressing for inclusions/deenergizings of a player, navigation on the menu, and a choice of a following/previous composition. The most unusual is scrolling there are casual elections of the next items from the list. And in the whole all is organized intuitively and more than thought over.
