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!

PRO-Active

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 Ω), and far less susceptible to noise and RF Interference (RFI).

1/4" In, XLR Out – There has to be More?

When it comes right down to it, all DI boxes do the same thing, right? Yes, in a manner of speaking, but the DI800 does much more than just “bass guitar in, mic-level signal out.” It really is a highly versatile input-signal toolkit. Here are just two advantages the DI800 has over standard passive DI boxes:

• Maybe you’d like to connect your guitar amp’s speaker output to your mixer? Not a problem, the DI800 features a -30 dB attenuation switch, allowing you to connect to speaker outputs rated up to 3,000 Watts – and convert them to balanced XLR outs!
• 
Weak incoming signal? The DI800 has a +20 dB switch, which really comes in handy for boosting low-level input signals to balanced signals with real power and rock-solid impact.

Of course, the DI800 provides a Link output for easy connection to other equipment, such as your onstage amplifiers and monitor consoles. Servo-balanced performance guarantees ultra-flat frequency response – and the gold-plated XLR output connectors provide reliable, low-noise operation. Per channel ground-lift switches eliminate ground-loop hum issues. The DI800 does everything a standalone passive DI can, and much more – times eight!
