1. D1120 adopts high-quality aluminum alloy shell, one-time forming, sturdy and durable, and strong impact resistance. The appearance is small, the design is simple, and it is easy to carry. 2. Adopt the quality baking paint to spray and bake it through the advanced dust-free painting process. So as to achieve its surface is delicate, smooth and shiny, and the super adhesion of the baking varnish has strong anti-rust and anti-scratch characteristics. The three colors of blue, red, silver and white can effectively prevent signal confusion when multiple DI boxes are used on the stage 3. Musical inst ent output is generally high impedance output, which is to obtain high-fidelity details in a subtle environment. However, high-impedance input is too high for ordinary mixers and sound cards. 4. There will be two consequences if directly plugged in: 1. Loss of a lot of sound details, 2. No power. Therefore, the D| box is responsible for the high-impedance sound. After the signal is finely restored, it is sent to the mixer or sound card for use 5. D1120 is a dual-channel passive impedance converter that can convert high impedance signals into low impedance signals. No battery or fantasy power supply is required for use. In a variety of applications, D120 is a very useful and multi-functional tool that can easily connect various audio devices together.<br><br>It is especially suitable for musicians such as keyboards, electric guitars and basses, or other musical inst ents that need to insert signals on the stage. Grounding selection switch and 2 gear attenuation. High-quality passive impedance converters are mainly used to convert high-impedance signals into low-impedance signals Product category: Impedance converter Model: DI120 Brand: Alctron size:170x30x180mm Material:ABS colour:Blue<br><br>Package Contents: 1 x Impedance converter<br><br>Only the above package content, other products are not includ
