Magic Eye 6E2 EM87 Preamp Tube Audio Level Indicator VU Meter Driver Board +Case
6E2 tube magic eye driver board adopts Douk Audio core power technology, more convenient and simple to use, effectively reduces the power consumption of the circuit, and the PCB uses a large number of SMT components.

Features

1. Adopting universal DC power supply mode DC (5V-7V), and can also be directly powered by standard USB 5V, such as mobile phone charger or computer USB interface. Can be regardes as the lowest power consumption among the same kinds of products.

2. Reasonable optimization of PCB size, reduce the chassis space occupied, the wiring is simple and clear.

3. The potentiometer is provided with a level display range adjustment, more convenient to adjust it.

4. Built-in secondary signal amplification, higher sensitivity, and adjustable level display.

5. Built-in electronic boost circuit, not use the 250V transformer required for traditional driver board, saving more money and space.
