The Radial StageBug SB-15 DI Box is the ultimate companion for your pedal chain. Whether you’re on stage or in the studio, this DI box will provide crystal clear audio with up to 50ft of perfect signal integrity. It has a simple yet powerful plug and play design, and it is ready for any eventuality with its buffered inputs and outputs. Additionally, it can quickly convert two 9V supplies into a 15V output. The SB-15 is also portable and practical, designed to fit neatly into your instrument case and constructed to withstand knocks and drops. By using the SB-15, you can guarantee a professional sound.
The SB-15 combines performance with practicality. It is ultra-compact without compromising on quality, thanks to its 100% discrete Class-A design that ensures your instrument’s tone remains uncoloured. This design reduces the need for phase-cancelling negative feedback, resulting in natural sound perfect for any pedal board. The SB-15 also features a drag control load connection, which makes your pedal chain less susceptible to buzz, radio interference, and unwanted noise. With this feature, you can drive multiple pedals up to 50ft without signal degradation.
Key features of the SB-15 include the ability to drive multiple pedals without unwanted noise or signal loss, pristine signal integrity thanks to a 100% discrete class-A buffer, the capability to drive pedal chains up to 50ft without signal degradation, and the ability to quickly convert two 9V supplies to a 15V output. The SB-15 also provides uncoloured sound for your guitar with a hi-Z buffer input and allows you to connect your pedals to your amp with longer cable runs via the buffer output. Its robust construction protects against knocks, scratches, and scrapes, ensuring it stays looking great for years to come with its sleek powder coating.
The SB-15’s specifications include a class A FET buffer audio circuit, a frequency response of 20Hz – 30kHz, total harmonic distortion of 0.01 @ 1kHz, a dynamic range of 104dB with a dual 9V supply and 98dB with a single 9V supply, an input impedance of 22kΩ – 500kΩ, and an output impedance of 4.7kΩ. It has a maximum input of +16dBu and a gain of 0dB (unity gain). The clip level output is +16dBu, and the noise floor is -88dBu. Other specifications include intermodulation distortion of 0.004, phase deviation, audio connectors of 1/4″ unbalanced Hi-Z I/O, and controls such as the Drag Control Load Correction Circuit. The power input is dual 9VDC 200mA for optimal performance, but it can also be used with a single 9VDC supply to power the buffer only. The power input connector is a standard 2.1mm barrel with center negative (-), and the power output connector is a standard 2.1mm barrel with center positive (+). The power output is +15V DC 400mA. The housing is made of steel, and it has a durable powder coat finish. The dimensions are 4.5 x 1.85 x 1.35 / 114mm x 47mm x 34mm (L x W x D), and it weighs 0.55lbs / 250g.
