OUTPUT: Connect the PA system with a three-core XLR cable LIFT-GND: When you set the switch to FT, do not connect to the case: When you set the switch to GND, connect to the case PAD:- The 10B attenuation switch is used to attenuate the high impedance output. INPUT: Use a 1/4inch cable to connect to the UNER: send the signal to the amplifier or mixer Brand- color scheme The dust-free spray paint process s0201 adopts a brand- color scheme of carmine and high-grade gray, which fits well with the audience's psychological questions and avoids the problem of equipment confusion in the complicated stage links. The dust-free spray paint process is adopted to make it have a more delicate surface texture. Professional signal processing provides good signal balance and output solution 01 is an active D box. Can provide musicians with professional-level signal transmission and conversion solutions. he SD201 circuit design can reduce the impedance and effectively reduce the noise at the same time. Based on this, your signal will be rushed and balanced according to the optimized parameters. The S0201 body circuit needs to be powered by the 48V fantasy power supply of the mixer and other equipment, so you no longer have to worry about the lack of power or insufficient power supply caused by the external battery, plug and play. You can enjoy natural and full sound even at low output No sound pollution and noise reduction active impedance converter stubborn line to reduce noise and noise, the design of active line is to choose the anode Audio-visual accessories type: DI effector Brand: Alctron Colour:red Material:ABS Size: 50 x 119 x 38mm Package Contents: 1x Impedance converter
