The Radial SB-1 Acoustic is a high-performance active direct box made for
players that are on the move. Made to fit inside a guitar case, the SB-1 is the
smallest Radial DI box ever! But don't let the small size deter... this
ultra-compact StageBug sounds absolutely terrific!
The design begins with standard ¼ instrument input with a thru-put to feed
your tuner or your on-stage amp. The ultra-quiet active circuit at once converts
the signal from high to low impedance to reduce susceptibility to noise. The
signal is then buffered and balanced for long cable runs to the PA system. 48
volt phantom provides the power, so the SB-1 does not require batteries or
external supply to make it work. You simply plug in and you are ready to
The active circuit features a carefully selected 800k-ohm input impedance
to eliminate problems with loading while delivering a crisp, clear sound to the
audio system. This delivers extra sparkle to the top end when interfacing
vintage guitars with low output pickups and is particularly handy should you
plan to use it for recording or Reamping. The SB-1 is also equipped with a -15dB
pad that reduces the input sensitivity to gracefully handle even the loudest
active instruments. This makes the SB-1 perfectly well suited for electric bass
and keyboards. To reduce feedback, toggling the 180° polarity switch helps
eliminate hot spots on stage that can cause low frequency resonance.
The StageBug... small size, big heart, huge sound!
