Review on MP3 player DIGMA Z4 16GB 16 GB, Bluetooth, black/grey by Anastazja Klementyna ᠌

As for the sound, this model and all other Chinese do not have a human equalizer, there are only presets. In all such players, the equalizer is apparently implemented at the codec level, and not in hardware, that is, it is not a physical tone control, therefore the signal level cannot physically exceed 0 dB (i. E. jump above units when processing a figure to the DAC), therefore it is impossible add the signal level, but you can only slightly attenuate some of the frequencies (top and middle), simulating the work of the equalizer. That is, it’s impossible to add bass in a human way, and DBB (bass boost) - in all such players - is just a slight attenuation of high frequencies or mids. In Walkman, for example, you can manually add individual frequencies by a few dB, so that you can adjust the normal sound on any headphones. So, if there was a real physical manual equalizer here, and instead of half-screen animation, a normal information line (3 lines) about the track, one could rate 5. And so - only a four. As usual with the Chinese, the track rewinds without sound. The radio catches mediocre. Where the Walkman NWZ-E453 only slightly rustled, this one already hisses and does not catch. Walkman fell silent only in the elevator, this is - already almost the entire entrance is silent. There is a recording from the radio, in WAV and MP3 formats, from 64 to 192 kb / s, but the recording turns on with a very long delay, about 6-8 seconds. when auto-search, there are a lot of false stations (empty, with interference), and a working display gives strong interference to the receiver. I also amused the countdown when the Power button was pressed. When you turn off, when you hold the button, a countdown to 3x appears on the screen, which must be sustained. Never seen this anywhere. another moment, at the first attempt to upload music to the built-in memory, the speed was extremely low, about 1-2MB / s, and constantly falling. After formatting in the player itself (through the menu), everything worked quickly. After - everything is stable.
