A-Designs REDDI

The A designs REDDI Tube Direct Box is a unique unit. By “unique” we mean the effort placed into the REDDI to produce a sound and character all its own. That effort took A Designs Audio back to a place in time when the Ampeg B15 reigned supreme – making liberal use of tubes and transformers. The A Designs REDDI endeavors to not only rebuild that tone, but also bring that sound to pro audio. Plug a Bass into a REDDI and it’s a step back in time. Thick, round, solid sounding Bass notes that sit perfectly in the mix. A Designs REDDI is also great for guitars, synths, and any other electronic instrument that requires a direct box for recording. In fact, some recording engineers have said that REDDI is the “best tube DI ever made.”

Tube Direct Box

The A-Designs Audio REDDI does not add tremendous amounts of gain as the point of this DI is tone, not huge increases in volume. A tube-based amplifier using the 6N1P output tube feeding an A Designs custom-wound output transformer provides the circuit path for your guitar or bass giving you a sound that you can’t get through any other device.

Its all about the transformers

With any Tube gear, one of the key factor is transformers; both audio and power supply transformers. A Designs Audio custom-builds their own unique audio output transformer to produce the specific sound they’re after. To keep the REDDI at its lowest noise level A Designs employs a special toroid transformer in the power supply – no wall warts or off the shelf transformer here!

Combo XLR/1/4″ input connectors

Using the combination XLR and 1/4″ input connectors makes the REDDI a more versatile unit. The 1/4″ will handle the bass, guitar, keyboards, and MPC/Drum machines, while the XLR can be used with dynamic microphones for recording duties on snare, kick, or other instruments. The REDDI now ships with a 1/4″ through-put as well.

Drop Dead Red Metal Casing

It is only fitting that a unique box like the REDDI should look unique. With a long chassis and a fire engine red finish (Red DI, get it?), the REDDI is impossible to miss even in a dark recording studio. The bright blue LED Power indicator can be seen across the stage, which makes the REDDI a very attractive package for both the engineer and musician.
