At the performance venue, the output signal of some electroacoustic instruments is a high-impedance, high-level signal, and is unbalanced. If the output of this kind of instrument is directly connected to the LINE IN the mixer, when the connection line is long, the unbalanced transmission of high impedance is easy to be subjected to external electromagnetic interference to produce "sizzling" interference. The signal of low Yang resistance is transmitted through the flat street type, even if the distance is far, it is not easy to be interfered with. Therefore, at the performance site, the high-impedance non-balance signal output of electric acoustic instruments such as electric guitars is input to the 01 box, and the DI box is converted into a low-impedance signal, and this interference noise can be avoided through balanced transmission.
SD201 has the following new features: active circuit design, aluminum alloy design product is durable, deeply optimized signal buffer and balance at the same time can be plug and play easy to use, but also can support low output sound quality enhancement and restoration, the appearance of a new color scheme using dust-free painting process.
1.OUTPUT: Connect and send balanced low impedance signal to the PA system with a three-core cannon XLR cable
2. Lift-gnd: When you switch to LIFT, no case is connected: When you switch to GND, the case is connected
3.PAD: -10dB attenuator switch is used to attenuate high-impedance output
4.INPUT: Use 1/4 "wire to connect
5.TUNER: Transmit unbalanced signal to amplifier or mixer
OUTPUT: Connect PA system with three-core cannon cable
