Ujjdwiurgh AU-105RCA Audio Distributor Stereo Audio Mixer 1 Input 5 Output Multi-Channel Audio Distributor for Volume Controls

Input and output are lotus interface, one set of two-channel audio input, five sets of two-channel output, can be connected to five power amplifiers or active speakers, with gain compensation 2 times amplification; Please use a low-ripple power supply for power supply, pay attention to the positive and negative poles, they burn if they are connected reversely! The power interface 5.5*2.1 is positive and negative. The volume of each group is controlled separately, and the gain compensation is about 2 times (6DB) The internal use of positive and negative power conversion circuit, the actual power supply is doubled, the operating voltage range is DC 5V-16V, and the Japanese company NJM4580 dual op amp is used. A total of 6 chips are used, 1 chip is used as a gain boost, and 5 chips drive five groups respectively. Stereo output, low noise and high fidelity, long-term power on and stable work; Working voltage: DC5-16V, with negative voltage conversion, the power supply voltage is doubled and the dynamic range is large.
