This product has a number of options, you can choose the finished board, you can choose the whole machine to buy. The manufacturer is no such materials and technology, in addition to advertising blowing in a complete mess outside. This is done using HIFI material out of the Cara OK level, the effect is completely different.
Do a lot of m65831 the seller, 99% of which is in order to cater to the sales and production, has a fatal flaw. The first is their OK the board did not delay time knob, adjust the depth of the only reverberation echo, reverberation time fixed dead, there is no way to make sing K achieve the best results.Also almost no 1 using the microphone auto squelch function, do not plug into the microphone and karaoke noise as overflow music signal interference. Cara OK we specialize in designing professional design
The whole machine is a good test of the whole machine, all aluminum alloy, the power can be used normally, the price of 248 yuan
Finished board is not with the transformer and the shell, the board is a good test, suitable for DIY user price of 83 yuan
* * * general manufacturers of M65831 programs are using a fixed delay time setting (IME DELAY) can not be adjusted, the exclusive use of the product adjustable technology, to achieve the professional effect of KTV. And the use of natural audio reduction circuit.
1 using the microphone automatic mute circuit, when the microphone is not inserted, the words put some circuit completely isolated, does not affect the music playback, the background is better
2 do not use those cheap single sided circuit board production, and horizontal seven Shu 8 pieces of domestic and low so-called imported parts, the full board is iron fly line and the so-called fever. This product uses a lot of 1% patch, really neat import resistance volume and production process
3 input operational amplifier with the OPA275 amplification and output with double precision JRC5532, than other similar products by Ti produced ne5532 much better. JRC4558 these low-end is more not said, is the core of the Sanling m65831, force analysis, sound natural and delicate, board also set are exclusive of the reverberation time adjustment.
4 without the use of inexpensive single joint potentiometer, all of Taiwan sealed double potentiometer parallel connection.
5 even if you do not use the card it OK, it is also a superior performance of the previous stage, with a gold plated input and output terminals to facilitate the use of
(also can be purchased when not to install the terminal, in order to fit their own installation and use)
6 input voltage for AC12 to AC18VX2 (the whole user can not be ignored, directly connected to the 220V can be)
Use matters needing attention:
1 reverberation depth and time is not the longer and deeper is good, adjust to the most natural is really too long delay effect of the signal to noise ratio,
2 to use as far as possible, such as using a simple metal box shielding ground, in order to obtain the best signal to noise ratio
