Description:
This product is the entire circuit board trace layout rigorous reasonable, stable and reliable, high output power; beautiful mellow sound,open sound field. Dimensional sense of strong, powerful low-frequency sound calm, very good signal to noise ratio, wide dynamic range; details clear, excellent transient response, play a variety of music all rise to the occasion at home playback environment has a very good performance.
The main chip using imported IRS2092 with digital audio and IR company dedicated MOSFET FET IRFB4212 well-designed, the entire board
With the Japanese ruby, chemical, EPCOS other high-end capacitor.
Using expensive materials imported from Germany red gray T130 surround inductors, to ensure crisp and powerful sound.
Main parameters:
- Supply voltage: Dual DC power supply ± 40V --- ± 50V
- Maximum output power: 200W / 8Ohm, distortion <0.1%; 350W / 4Ohm, distortion <0.5%
- Efficiency: > = 90%
- SNR: 90dB
- Recommended Speaker: 4 - 8Ohm
- Board Size: 125mm * 91mm * 47mm (L * W * H)
Precautions:
- The supply voltage can work in dual DC ± 40 --- ± 50V, recommended ± 48V DC dual power supply filtering better.
- The amplifier section does not fit directly connected potentiometer, If you want to adjust the volume, please In the source-side control, Or add a good preamp.
- The speaker recommended 4 ohm or 8 ohm!
- Check carefully before electricity, ensure the wiring is correct before electricity after.
- The board Voltage is fixed at 47 times magnification, if the output power is not enough, as the case may add their own pre-amplifier.
- This is a finished board weld test OK.
Note: The circuit board assembly due to different batches, PCB color and on-board assembly of the components will be different!
