Parameter and description:
This price is the price of dual-channel finished board, the default LM1875T for horizontal installation.
Each PCB size: 76 * 120 * 1.6MM FR4 A-class board, double single independent channel design.
Input voltage range: AC15-0-15 to AC21-0-21, AC21-0-21 is recommended.
Dual-channel transformer power not less than 100VA
Highlights of this version:
1, reference to the original GC line, unit parallel outputs
Whether the GC version or the public version of the single-tube LM1875T, can not escape the chip's own weaknesses: dynamics, control - drive - poor detail embodiment of the problem. After the use of parallel units, this weakness can be strengthened.
2, filter capacitor array
ELNA 5600uF X8, each channel high 44800uF filter total, with SEP high-speed rectifier bridge + filter capacitor array, low power supply resistance, high dynamic response speed;
Filter capacitor array in the amplifier class use the benefits of too much, low power supply resistance, high-speed charging and discharging, etc., in this application in parallel with the 1875T, the starting point of the finishing touch to the effect of strong dynamics, low-frequency without dragging the mud.
3, join the 1237 amplifier protection circuit, corresponding to the protection of your box, OMRON power relay, high reliability!
4, double single independent channel design, physical 100% separation, wide soundstage, positioning accurate
5、Double single independent design is another advantage, dispersion of heat.
GC version of the 1875T heat should not be underestimated, especially in parallel, slightly louder than normal listening to the sound, the mono channel heat can compete with the 7-watt small Class A back stage.
6, compared to similar products, this version of the coupling capacitor using MKP, ZERO-ZONE AB compared to the same capacity of electrolytic \ BP \ MKP non-polarized coupling capacitor (from 2.2 test to 10UF), and ultimately decided to use the MKP 3.3UF, the overall performance of the delicate, smooth, low-frequency powerful but not muddy, elasticity is still very good. Overall noble feeling.
Package:
1pair Reference GC line parallel version of the LM1875 amplifier board finished plate
