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 - scheme The dust-free paint process s0201 adopts a - 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 paint process is adopted to have a more delicate 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 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 : Colour:red Material:ABS Size: 50 x 119 x 38mm Package Contents: 4x Impedance converter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
