This product is specially designed for players who like the sound of electronic tubes. The human voice is very warm, the high frequency is sharp, the low frequency is soft, and the sound is very pleasing and comfortable. One channel is output by 4 pieces of LM1875, the quiescent current is 4 times higher than that of a single piece, and the current of the whole board is about 0.5A. It is pure Class A state at small and medium volume, and it is more comfortable than 1969 Class A.

The core circuit is the GG version, the full name is Gaincard. It is a very sound LM1875 circuit optimized after repeated comparison and verification. The frequency bandwidth, delicate, durable, midpoint and stable, if you have not played LM1875 before, it is recommended to buy Try it, if you have bought LM1875, you can even buy it as an upgrade.

The principle is that the voltage at the two input terminals of the inverting amplifier circuit is always 0 and does not change with the input signal. The input voltage of the transistor (field effect tube) at the input of the amplifier is constant, and the bias state always maintains the appropriate operating point.

Generally, a single output of LM8175 is 4A current, the official indicator, low drive sensitivity, heavy-duty speakers, it is useless with BTL, the drive power will not be able to do so, the use of 4-link output can double the drive current to 16A current. , So that the sound field is better, the mid and low frequencies are fuller, and the power is also improved.

Product Highlights:
*Using a good-sounding CG circuit architecture, the sound is very delicate and durable, with a stable midpoint. 4 parallel X2 Class A outputs
*40000UF large-capacity filtering, excellent low-frequency dive
