In the negatives, it is officially sold in Greece without instructions in the Greek language, based on EU law allowing the sale of goods without Greek instructions, as it is a small language. Some people write that it has instructions in Greek, but in my box, from Greek import, it did not have them, and there is no way to download them from the internet.
It has a difficult menu, but it can adjust everything, and it is necessary to adjust it, otherwise you will say it has no sound, I cannot be heard from the phone, etc.
Attention, attention, no support for the Smart Sync app, only the 420BT supports it, but not the 320BT.
I connect with BT to the iPhone and the "Music" app from Apple, or with YouTube Music, but not with Smart Sync.
The CD plays so far.
The screen can be adjusted for brightness.
The phone connects normally to everything, you adjust the microphone if you want to be heard well because you can hear them comfortably from the speakers.
I bought it with the latest firmware installed, 08.14.
In order for the device to deliver its sound capabilities, you must definitely adjust the EQ and adjust each frequency one by one if you want to hear correctly without distortion and squeaks, there is a guide at the end.
Also, adjust at what volume you want the front and rear speakers to play, and I'm not talking about the known fader but another special adjustment it has, which, along with the EQ adjustment, reaches perfection, no matter what speaker you put on it, it just takes a lot of searching to find out what the device can really offer you because the menu requires learning.
There is a frequency adjustment guide for all Pioneer devices in foreign forums, as always... because here, they only care about what color it comes in.
* 50 Hz: You can control the bass at this frequency. However, it is not necessary to add this setting if there is no subwoofer installed in the machine. You can unnecessarily "overload" the speakers and have the opposite result. If the subwoofer is present in the speaker system, a slight gain in this range will provide depth.
* 80 Hz: This range is responsible for the saturation and density of the bass. When adjusting at this frequency, you must be very careful because the main acoustics and the subwoofer are more often found there.
* 125 Hz: At this frequency, you can control the impact of the bass and the power of the sound pressure. If you abruptly weaken this range, the sound may lose color, sharpness, and become dull. But with excessive amplification, the bass can become too harsh. Therefore, the adjustment must be done very carefully and attentively.
* 200 and 315 Hz: Interference is caused at these frequencies due to cabinet tuning. It is necessary to slowly raise or lower the indicators until you achieve the most natural sound. It should remain saturated without boom and echo.
* 500, 800 Hz, and 1.25 kHz: These three bands can be considered the most important and informative, as this is where the human ear perceives the majority of sound. When adjusting, it is recommended to use a recording with voice, as this will help you quickly catch an unnatural sound. Keep in mind that if you weaken the sound significantly in these frequencies, then the sound will be dull and quiet, without color. Excessive power here threatens with a "telephone" sound when the voice is distorted.
* 2 and 3.15 kHz: These two bands are responsible for the readability of vocals and the recognition of sound from many musical instruments. If you weaken them unnecessarily, you will get an unclear and inaudible sound, while sudden amplification can cause a tiring sound.
* 5 kHz: Responsible for the clarity and purity of sound transmission. Weakening it makes the sound dull and monotonous, while increasing it makes it very bright, sharp, and often very unpleasant for the human ear.
* 8 kHz: Adjusting to this frequency will allow you to adjust the clarity of reproduction, especially regarding hissing sounds. The easiest way to tune in to compositions with vocals. This way, the difference will be more noticeable.
* 12.5 kHz: This is a very high frequency, usually not containing fundamental tones of musical instruments. However, it is also very important, as it allows you to adjust the sound from tones that can make the sound more airy if you add an indication. However, you need to know when to stop, if you overdo it, it will whistle at you
