The core of the pre-stage is the M62446 chip, which is an integrated 6-channel high-quality volume controller. It was originally designed by Japan`s Sanling, and is still in use by many first-tier brands at home and abroad. Many brand machines with prices ranging from 1 to 5K are still used in large quantities. They have much better sound than PT2313 2314, M62429 and other series, and the low frequency is full and high frequency is delicate.
M62446 can be used as HIFI-2 channel or 6-channel AV. M62446 has a HIFI 2-channel dedicated input channel inside, which is very suitable for high-quality audio source control such as CD. The channel error is less than one thousandth.
