1. A single passive impedance converter can convert high impedance signals into low impedance signals2. It is made of steel plate by numerical control stamping. DB-1 is made of steel plate by multiple numerical control stamping. It has a strong and durable structure, strong impact resistance, appearance, simple design and convenient carrying.3. Working principle: The output of musical instruments is generally high-impedance output. However, high-impedance input is too high for ordinary mixers and sound cards, and there are two consequences if it is directly plugged in: 1. Loss of a lot of sound details, 2. Ineffective. Therefore, the D box is responsible for restoring the high-impedance sound signal and transmitting it to the mixer or sound card for use.4. Work : The main of the DI box is to transmit the signal of the instrument to the mixer or directly through the DI box to the mixer or . The sound of the instrument can be obtained without restoring the instrument speaker;5. the of computer recording, the instrument The signal is input into the computer sound card through the DI box to obtain the instrument sound. If you use a computer such as Guitarrig, you can directly use the computer as a professional .Other applications: DI boxes are generally equipped with direct output, which is mainly used for stage performances. Musicians insert instruments on the DI box. The DI box is divided into two outputs, one DI signal is output to the mixer, and the tuning is guaranteed. The teacher obtains the signal; the other direct output can give the instrument speakers on the stage just like the instrument is directly plugged into the speaker. The habits and adjustments of the musicians using the instrument speaker do notneed to be modified, and the tuner does not need to set up a microphone in front of the speaker Wait for . This is why many professional sites are equipped with a number of D boxes: Model: PS-1Rated voltage: 9 (V)3C rated voltage range: 36V and size:120x76.5x45mmMaterial:metalcolour:BlackPackage Contents:1 x Impedance converter
