Description
Product Q & A
Review
This is one pair assembled and tested amp board. include 2 channel amplifier boards.
PCB size:76*120*1.6MM
Works voltage: AC18V-0-AC18V (AC15V-21V are all ok)
Output impedance: 4-8ohm.
Output power: 30W +30W at 8ohm load
The GC version is the full name of Gaincard. It is a very good LM1875 circuit that has been optimized through repeated comparison verification. The frequency bandwidth, fineness, resistance, midpoint and stability
General LM8175 single output is 4A current, the official index, low drive sensitivity, use BTL are useless, driving force will be powerless, using parallel output, you can double the drive current to 8A current. , so that the sound field is better, the mid-low frequencies are more full, and the power is also improved
Highlight:
1: ELNA 5600uF X8pcs, 44800uF total filter per channel, with SEP high-speed rectifier bridge + filter capacitor array, low power internal resistance, high dynamic response speed.
2: with UPC1237 protection circuit to protect your speakers, OMRON power relay, high reliability
3:Dual single independent channel design, physical 100% resolution, sound field width, positioning accuracy
4: Coupling capacitor using MKP 3.3UF, the overall performance is delicate, smooth, low-frequency powerful but not turbid.
