It is possible to connect up to 8 channels simultaneously (up to 16 channels when using two) together with the function to supply power to the audio equipment sequentially. When the power is turned on, power is supplied from channel 1 to channel 8, and when it is turned off, channel 8 is blocked in reverse order, reducing power overload phenomenon or collision when power is supplied all at once. In addition, to prevent electric noise, the product itself can be grounded to suppress noise generation, making it possible to use precious sound equipment with peace of mind. For example, connect mixer to channel 1, outboard to the remaining channels, and power amp to the last 8 channels. On the front panel, the voltage status is displayed, so you can monitor the power supply status without a separate TESTER, and you can install the lighting device, so that you can work smoothly even in the dark environment. In addition, it is upgraded to one level by designing to supply power only to necessary channel among channels 1 to 8.
