Radial StageBug SB-2 DI-boksi

Radial SB-2 passive DI box – clean, reliable direct‑to‑mix signal

The Radial SB-2 passive DI box is engineered for musicians and engineers who demand pristine signal transfer without the hassle of external power. It offers a transparent audio path that preserves instrument tone from stage or studio to the mixing console.

What makes the SB-2 stand out

Equipped with a high‑quality Eclipse ETB3 transformer, a 15 dB pad for hot sources, and an automatic stereo‑to‑mono merge circuit, this model is housed in a rugged tabletop‑mountable chassis.

Signal quality and isolation

Strong transformer design and passive circuitry keep the sound free from hum, buzz, and noise, giving you confidence in any environment.

• Transformer: Eclipse ETB3 – delivers transparent tone and superior ground isolation
• With a Pad of 15 dB, users can control hot signals without coloration for stage or studio use.

Input and output flexibility

Whether in the studio or on stage, this instrument handles mono and stereo sources while preserving mono integrity.

• Stereo‑to‑mono merge: auto‑detects and sums – saves mixer inputs for keyboardists
• Input jack: ¼" TS – accepts passive guitars, basses, keyboards
• Mono output is provided via a XLR male, offering a balanced feed to mixers or interfaces.

Build durability and stage readiness

The metal chassis and tabletop mount let the unit survive the rigors of live performance.

• Mounting: tabletop‑ready – fits in cases and on stage stands
• Hum from ground loops can be eliminated thanks to the Ground‑lift switch (on/off).

Who is it for

SB-2 is the right choice for gigging guitarists, bassists, keyboard players, and studio engineers who need a compact, passive solution that keeps tone pure and setup simple.

Radial engineering heritage

Radial Engineering has built a reputation for durable, high‑performance direct boxes since the early 2000s. The Stagebug SB-2 continues that tradition with modern features at an affordable price.
