There are no questions for these dengue. Even the receiver catches perfectly, if the wiring is hooked and this is in the village, where in principle it sucks to catch radio. The sound is quite normal, but a powerful power supply is very important. Connected to the computer unit for 300 watts, the first. At 250 did not pull, calmed the voltage. I disassembled everything, the wiring shielded, the Philips output assembly, is fixed on the radiator housing.
It seems to me that the HY-502 will be solid. But it costs almost once more expensive. A little fonite at idle. I will collective farm. But in general, for their money a decent device. HY-502 lives in the country for three years. This one took to the garage.
In general, it works! Sound good! Receiver shit! I have in my room, all modules 8 pcs, catch 32-34 stations! This 21 with noise! Sd cards are very quiet! You have to add volume! No bluetooth and aux input in front! I'm a 52-year-old radist! Decide yourself! It is easier to buy a module and a chip!
Went month, flash 32 does not read, 16 did not try, 8 and below read, there are no wires, bought the power plug and solder itself (could throw the cheap plug into the box) on the radio some channels with interference, mostly norms. When listening, the flash drive climbs the crack as if the phone receives a call, changed the places of installation and somewhere disappears. I tried to hang 4 columns 4 + 10-4 + 10 watts and alas, it overheats although in instructions 20 + 20, in general TTX does not quite match. As a result, left 4 + 10-4, the sound of a nice bass is, there is no headphone input. Yes, it's okay, it will.
