The DI-400x is four discrete, high-quality, professional-grade active DI box for touring sound applications and recording studios. It has a major advantage over other high-end DI boxes on the market, with its built-in Sonic Maximizer processors which employ the BBE 4th Generation Processing Engine - just like the 482i and 882i Sonic Maximizer models. The DI-400x yields excellent results with active or passive bass guitars, keyboards, and both acoustic and electric guitars.   The DI-400x is an excellent choice for transferring any musical instrument signal direct to a mixing console.

Above all, the DI-400x was designed without compromise, with paramount importance placed on maintaining the highest sonic integtity. All of the switches, pots and connectors are connected directly to its military-spec circuit board, rather than “fly-wired” to the PC board. The primary advantage of this design is that allows the legs of most board mounted components to be dramatically thicker than the narrow conductors commonly employed in many audio designs. All this in a musically engineered and massively constructed DI that can withstand the most demanding conditions.


• Four discrete full function BBE Sonic Maximizers for crystalline clarity and definition
• 15dB Pad Switch
• Ground lift switch
• Electronically-balanced XLR outputs
• Impedance-balanced 1/4” Tip-Sleeve output
• Military-spec circuit boards
• Extra-thick, extra-wide circuit board traces for unequaled electron flow
• 1% metal film resistors throughout
• Solid 1/8” thick aluminum extrusion housing for light weight and superb strength
• Recessed switches to reduce the opportunities for damage
• No-slip full bottom pad to stop slippage and prevent ground contamination through chassis to chassis contact
• Made with pride in the USA
• 5 year warranty

review of the BBE DI-1000 and DI-100x

“…they offer features unmatched by bargain DIs.”

“The Sonic Maximizer is awesome.”

“…each box is so tough and roadworthy.”

“Best of all, both models feature a Sonic Maximizer...”

“…each DI did a fantastic job of translating input signals with punch and clarity.”

“Both the DI-100x and DI-1000 are exceptional pro-audio helpmates that present your direct signals in the best light possible…”

“Guitarists who are always looking for ways to make better tracks in their home studios need to put one of these babies in their trick bag!”

I am interested in running my live guitar rig direct and miked. The miked part is done. I use three Mesa amps and two Crown amps live with options of running up to six amps simultaneously. It's a wet dry system. I send three sends to cabs dry and two or four sends wet. I use a Bradshaw system for switching. Will this BBE unit do good for me to get two drys and two wets to the board? Thanks for the help, Rg

BEST ANSWER: It should work perfect for that. You can put it any where in your chain and use the Thru's to keep your original chain then use the balanced outs to go to the mix board. Also the sonic maximizer's that are built in are great for fine tuning your tone.

Nice unit !
Pros: Easy To Use,Clear Sound

This unit is extremely quiet and it does allow an input signal via the rear "unbalanced out" plug which is a feature I really needed. When I called BBE and asked if the unit had an input in the rear of the unit I was told no, but I purchased a unit anyway due to the anticipated quality and reputation that the BBE DI units have. Turns out that the unit DOES accept an input signal in the back even though it's labeled "unbalanced out". The front input, the front "thru" and rear "unbalanced out" are all wired in parallel so if you want to use the rear
"unbalanced out" as an input rather than using the front input unit it'll work just fine.
It's a great unit and it's basically four BBE DI-100 units in a single rack unit.
