Enhance Your Sound with a Direct Box

Hello! I’m Kaoru, a composer.

Today I’ll be talking about the direct box (DI), which can elevate your recording and live sound quality. This is especially essential for guitarists, bassists, and keyboardists!

First, let me explain what a direct box is and its purpose, as many of you might be wondering, “What exactly is a direct box?” or “I’ve heard of it, but what does it actually do?”

■ What is a Direct Box?

A direct box is a device mainly used with instruments like electric guitars, basses, and keyboards. It converts an instrument’s unbalanced output to a balanced output, allowing it to send noise-resistant, balanced signals to a mixer.

Most direct boxes are straightforward in design, making them beginner-friendly. Each model has its own unique characteristics, offering depth for users to explore. They come in two types: active (requiring external power) and passive (no power needed), so you can choose one based on your environment.

■ When Do You Need a Direct Box?

Because it’s not a highly visible piece of equipment, you might wonder when you’d actually need one. Let’s break it down:

Recording:
While direct boxes are a staple in pro studios, they’re also great for home recording. Since most home setups rely heavily on line recording, I recommend a DI for achieving better sound quality.

If your audio interface has a Hi-Z switch, make sure to activate it for recording!

Live Performances:
They’re especially popular in live settings, such as concerts at live venues, often with acoustic or electric bass.

Instrument → Direct Box → Mixer → Speakers
This is a common setup that can deliver powerful sound without compromising audio quality.

With a simple setup like this, you can really bring out the best in your instrument!

Now, let’s go over some top picks from Sound House!

Countryman / Type85

This is a staple DI box.
I remember that the live venue I used to work with always had this on hand!

It’s known for its durable metal body, perfect for withstanding intense live performances.

Its compact design ensures great portability, and it maintains clarity for low-end notes, making it an excellent choice for 5-string basses.

Its simple design means no complicated setup is required. Highly recommended as a first DI box!

Countryman / TYPE85S Stereo DI

This one is the same model in a stereo version! Choose according to your needs.

Samson / MDA1 Active DI

This is a high-value DI box with a durable build and reliable performance. It’s amazing that you can get such a quality product for under 5000 yen in this day and age!

It features an active design, powered by either battery or phantom power, making it suitable for various setups. The sound stays true to the original, making sound shaping easy.

Plus, the unique blue color is a nice touch!

Rupert Neve Designs / RNDI

This DI box from Neve, a brand known worldwide for iconic equipment, is crafted with only the highest quality parts, ensuring a no-compromise product.

Just knowing it’s designed by Rupert Neve, a legend in the recording world, is exciting in itself!

The RNDI is versatile and can be used with a wide range of instruments—bass, guitar, acoustic instruments, keyboards, synthesizers, and even line outputs of professional audio equipment. Having one of these on hand provides great assurance.

Its compatibility with acoustic instruments is especially impressive! It captures the harmonics and natural resonance of an acoustic guitar so well that it makes you feel like a better player!

Rupert Neve Designs / RNDI-S

This is the same high-performance model but in a 2-channel version!

Summit Audio / TD100

This is a half-rack preamp/DI box, distinct from the other models introduced above.

The fact that renowned bassist and music producer Seiji Kameda uses it already makes it highly trustworthy. With its built-in tube, it delivers that rich, warm tube sound.

It also includes a loading control that allows you to adjust the input impedance. On the back, there’s a Phone Out jack, so you can directly monitor the sound.

That wraps up our discussion on DI boxes! They’re an essential tool for bringing out the best sound from your instruments.

If you’re struggling with sound quality or volume, consider trying one out! You’ll likely find yourself thinking, “I wish I’d gotten one sooner!” Give it a try!
