DollaTek Magic Eye 6E2 EM87 Tube Preamp Audio Level Indicator VU Meter, Music Spectrum

• Magic Eye can be used as an audio level indicator or a VU meter. You can see the tube light dancing with your audio signal. You can use it seperately or combine it with your devices, which is very useful and beautiful.
• The circuit of Magic Eye has been redesigned overall. Compared with similar products, it has much less heating, very lower power consumption and smaller size.
• It adopts SMT technology, which decrease the height of all circuit components. Optimized layout makes its wiring is more simple.
• It has bulit-in secondary signal amplification with higher sensitivity. Its amplitude can also be adjusted on the board.
• It has bulit-in voltage boost circuit and can be driven by DC 5V~7V (USB 5V is also supported). Please do not touch the board while working.

DollaTek Magic Eye 6E2 EM87 Tube Preamp Audio Level Indicator VU Meter, Music Spectrum (Vacuum Tube + Driver Board + Case) Notice: 1. The finished board has been burn-in tested and can be used directly when you receive it. 2. Dangerous voltages may be generated when the circuit is working. Please pay attention to safety. Introduction: 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.
