Description
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 safetyoduction: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 componentsures: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 spacemeters:Operating voltage: DC 5-7V or USB 5VPower consumption: ≤3.15W (DC7V) / ≤2.25W (DC5V)Net weight: 60 g / 0.13 lbDimensions: 80*47*22 mm / 3.15*1.85*0.87 inPacking List:1 x driver board with case1 x 6E2 tube1 x USB to DC power cord1 x Signal cable
