High-quality components to ensure VU3’s best working performance:
1. AC 250V 5A large current relay, easily to connect amplifiers and speakers with high power.
2. Built-in large power load resistor with metal wire winding, each channel supports up to 300W power input and output.
3. High-precision VU meter with peak LED display, and match perfectly with customized VU driver board.
4. Fully isolation transformer to acquisite audio signal to avoid crosstalk from VU driver board, ensure clear and pure sound.
5. Solid CNC full aluminium alloy case, large pure copper banana speaker jacks ensures minimum signal attenuation during transmission.

Warm tips:
1. For safer and faster delivery, the remote control may not include batteries (CR2025 3V), please prepare it by yourself.
2. Not connect VU3 to amplifiers whose actual output power is greater than 300W, or else VU meter may be damaged.
3. When power VU3 off, Amplifier B channel and Speaker 2 channel will be auto selected and can input and output audio signal normally. And when power VU3 on again, it will auto switch to the channels that are set before.
