Its volume level is too low. And the sound quality is not good enought.
Here is its specitication:
- 350 BHT
- LCD display for text and graphic with blue backlight.
- Display song name in English
- Play MP3 file from SD Card (or micro SD Card in SD adapter)
- Play MP3 file from USB Drive
- Receive analog sound from line-in, such as Laptop, iPod, GPS Navigator, etc.
- Frequency selectable from 87.5-108 MHz.
- Full functional infrared remote control
- 5 presets equalizer
To improve sound quality:
A very pointed soldering iron is needed. Because the circuit is very small.
Disassemble it. Then remove 2 resisters, and 2 capacitors.
And then short the connectors of 2 resisters that were removed.
The sound will be louder and little more treble.
If you want to use it with your laptop,
then you have to supply the power via USB port, instead of car charger.
You need to find an unused USB cable.
Then connect red and black wires to the circuit.
Plug USB into laptop's USB port, and Line-in cable into laptop's headphone port.
If you want to gain the range of broadcasting,
you can connect a small and long wire to the circuit's antenna (green wire).
If you got a new one with difference circuit layout, see here.
