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 DIs feature
“bu ered” inputs that respect your source
signal much better than passive DI boxes
can. Balanced signals leaving the DI800 are
extremely low-impedance (typically less than
680 Ω), and far less susceptible to noise and RF
Interference (RFI).

¼ " In, XLR Out – There has to be More?
When it comes right down to it, all DI boxes do the same thing, right? Yes, 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 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 ampli ers and monitor consoles. Servo-balanced performance guarantees ultra- at
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 DI can do, and much more – times eight!
Power Trip
Unlike their passive counterparts, active DI boxes require a power source to make their internal
electronics work. The DI800 provides two power options: 120 – 240 V~ from the nearest wall outlet
or power strip, or +18 to +48 V DC from your mixer’s phantom power supply.
