About Warm Audio Direct Box

Become a master of sound with the Active Direct Box, an essential tool for musicians and audio professionals. This high-quality, durable device is perfect for instruments with passive pickups, particularly acoustic ones. It also offers the flexibility to operate in "passive" mode, making it a versatile addition to your audio equipment collection.

The Active Direct Box from Warm Audio stands out in the market with its unique features and innovative design. It's not just a direct box, but a piece of engineering excellence built around the world-renowned CineMag USA Transformer topology. This ensures that your instrument's tone remains undiminished, whether you play the guitar, bass, keyboard, or any other stringed instrument.

Constructed with top-tier discrete components, this reliable direct box is housed in a rugged aluminum chassis. It's designed to withstand heavy use, whether on the road or in the studio, with switches, knobs, and connectors that are built to last.

At the heart of the Active Direct Box is the custom-wound CineMag USA transformer, designed for maximum sonic integrity. This ensures a warm, rich tone even after long cable runs. The extruded aluminum enclosure guarantees durability, making it a long-lasting investment for your audio needs.

One of the standout features of the Warm Audio DI boxes is the onboard variable pad knob. This innovative feature allows you to attenuate your input signal from -3dB to -30dB, giving you the power to tame any instrument input source. Additionally, the Thru-put jack, jumpered to the input jack, provides the convenience of sending your instrument's signal to a second location, in addition to the live mixer or recording device.

The Active Direct Box is also capable of taking a recorded signal at line level and sending it to another line input while simultaneously sending signal out of the XLR mic level output. This makes it an invaluable tool for connecting electronic instruments like guitars, basses, keyboards, or drum machines directly to a PA or recording system.

In essence, the Active Direct Box is a professional-grade tool that converts high impedance, unbalanced output signals to low impedance, balanced output signals. This conversion ensures that your instrument signals are at the proper voltage level for the PA or recording system, greatly reducing or eliminating connections that could cause tonal shifts and distortion. With the Active Direct Box from Warm Audio, you're investing in superior sound quality and innovative audio technology.
