The ULTRA-DI PRO DI800 is a professional mains/phantom powered 8-channel active DI-box. If you need a rack-mountable DI unit with enough inputs to accommodate everyone on stage, or in the studio – then you need to plug into the DI800! Direct Injection (DI) boxes make it possible to connect guitars, basses and keyboards (as well as other line-level devices) to audio mixers and recorders. They are absolutely essential for proper impedance-matching and to maintain signal integrity. Our active DI800 features “buffered” inputs that respect your source signal much better than passive DI boxes. Balanced signals leaving the DI800 are extremely low-impedance (typically less than 680 ?), and far less susceptible to noise and RF Interference (RFI). • Professional and multi-purpose 8-channel direct injection box for stage and studio applications • Provides impedance and signal matching for the direct connection of instruments to mixers and amplifiers • Ultra-flat frequency response due to servo-balanced operation • Optional mains or phantom-powered operation • Allows direct connection to speaker outputs with up to 3,000 Watts • +20 dB gain switch for pre-amplification of low-level signals • Switchable input attenuation allows input levels of up to +40 dB • Ground Lift switch eliminates typical ground loop problems • Link output for easy connection to further equipment • 1/4" TRS and gold-plated XLR connectors • Illuminated switches enable perfect operation in dark stage environments • Internal switch-mode power supply (100 - 240 V~) for noise-free audio and low power consumption • Designed and engineered in Germany
