Radial Firefly Tube DI, 2-inputs, class-A,12AX7 tube drive, transformer isolated output
High Output Vacuum Tube DI Box
The Radial Firefly is a studio quality direct box designed as the product of the combination of detail and clarity of an active DI with a tube drive circuit capable of providing a vintage warmth and pleasing harmonics to any instrument.
When examining the specifications, it is vital that one should differentiate between products that are designed to provide accuracy compare to those that is designed to enthral and color. The Radial Firefly is designed to color and enthral. That means that, the specifications are normally used to qualify ‘accuracy’ have been removed leaving those that are still relevant such as noise. It is also important to consider that tubes are inherently noisy versus the solid state devices, so in terms of this matters, the specs may only seems to be less than ideal. But keep in mind that tubes is capable of bringing a sonic character that will surely exciting. With the Radial Firefly, in order to appreciate, one must really listen.
Fatten up your DI tracks
The Firefly's drive circuit utilizes a 12AX7 vacuum tube, which is the most popular tube made today and can be found in nearly all guitar amplifier designs. This helps provide the character and feel of a vintage device, while still maintaining low distortion and noise profiles common to modern pro audio equipment. The Firefly excels when used on instruments that sound too clinical or one dimensional when recorded directly, adding punch and warmth to bass or guitar tracks both on stage and in the recording studio.
Features
- 12AX7 tube drive and class-A front end
- Dual inputs with separate gain & remote switching
- Drag control load correction for optimal tone
- Variable output connects directly to a PA
