Radial Engineering Firefly Active Tube DI – Direct Injection Box Firefly

Firefly Active Tube DI – Direct Injection Box

SKU: Firefly Categories: , , Tags: , , , , , , , , ,

DESCRIPTION

he Firefly™ is a studio quality direct box that combines the clarity and detail of an active DI with a tube drive circuit that provides vintage warmth and pleasing harmonics to any instrument.

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.

The Firefly is perfectly suited for doubling on stage using two acoustic instruments. The 4 meg-ohm piezo input enables direct connection without a preamp.
