1. D1120 features a high-quality aluminum alloy shell, formed in one piece for durability and strong impact resistance. Its compact, minimalist design makes it easy to carry. 2. Finished with premium baked enamel paint applied via an advanced dust-free painting process, the surface is smooth, glossy, and highly resistant to rust and scratches. Available in blue, red, silver, and white to help distinguish units when using multiple DI boxes on stage. 3. Most musical instruments output a high-impedance signal to preserve fine audio detail in quiet environments. However, standard mixers and audio interfaces typically require low-impedance input. 4. Connecting a high-impedance instrument directly to such devices may result in loss of audio detail and insufficient signal level. A DI box converts the high-impedance signal to low-impedance, ensuring optimal signal integrity before routing to a mixer or audio interface. 5. The D1120 is a dual-channel passive DI box that converts high-impedance signals to low-impedance without requiring batteries or phantom power. It is ideal for connecting keyboards, electric guitars, basses, and other instruments to professional audio equipment. Features include a ground lift switch and two-level pad attenuation.
