## Description

The Radial StageBug SB-15 is a versatile audio interface designed for pedalboards, functioning as both a hi-Z signal buffer and a DC power adapter. It utilizes a 100% discrete Class-A FET signal path to ensure optimal signal transfer and includes Drag Control load correction to properly match the source pickup with the pedal chain.

This device effectively lowers impedance and susceptibility to noise, allowing for longer cable runs without signal degradation. For users requiring a 15VDC supply for Tonebone devices, the SB-15 incorporates a DC-to-DC converter that transforms two 9V supply lines from a typical power brick into the necessary 15 volts. Its robust construction features 14-gauge steel, making it durable for live use.

Key specifications include a frequency response from 20Hz to 30kHz, a dynamic range of 104dB (with dual 9V supply), and a clip level of +16dBu. The input impedance ranges from 22k to 500k Ohms, while the output impedance is 4.7k Ohms. The unit operates within a temperature range of 5°C to 40°C and is designed for dry locations only.
