Item Description
Listed 11 months ago
Here we have an A Designs REDDI V2 Tube Direct Box.
Used only a few times in a recording studio setting.
Unit is in mint working and cosmetic condition.
Comes with original box and IEC power cable.
The A Designs REDDI V2 Tube Direct Box lifts the same tone and sound from the circuit of the original REDDI and puts it into a rackmount chassis, bringing a whole new world of tonal possibility and convenience to keyboard players, guitarists, drum-machinists, and (of course) bass players the world over. Now you can tour the world with your REDDIs safely stowed in your rack!
The A Designs REDDI V2 offers a unique circuit. By "unique" we mean the effort placed into the A Designs REDDI V2 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 V2 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 V2 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 A Designs REDDI V2 is the "best tube DI ever made."
Tube Direct Box
It is important to note that the A Designs REDDI V2 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 A Designs REDDI V2 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 A Designs REDDI V2 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 A Designs REDDI V2 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 A Designs REDDI V2 should look unique. With a long chassis and a fire engine red finish (Red DI, get it?), the A Designs REDDI V2 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 A Designs REDDI v2 a very attractive package for both the engineer and musician.
