Radial StageBug SB-2

The StageBug SB-2 is a compact passive direct box that is perfect for active basses and keyboards, is small enough to fit inside an instrument case, and features a stereo to mono mix function to save mixer channels.

• Passive DI for bass, acoustic and keyboard

• Ultra compact to fit in your guitar case

• Plug & play easy to use feature set

• Transformer isolation eliminates noise

Small size and big performance
The compact design begins with a ¼" input and thru-put to feed the on-stage amp. This connects to the custom made Eclipse ET-DB3 transformer which performs the impedance matching and balances the signal. When using extra high output instruments, a -15dB pad can be inserted into the signal path. This enables the SB-2 to be used with active basses and digital pianos that often tend to overload the input side of the interface. An innovative stereo-to-mono merge function provides a convenient way to connect stereo keyboards and computers without having to reset the source for mono operation, saving time and input channels on the PA. The SB-2 output features an XLR wired to the AES standard with pin-2 hot. Once connected, the SB-2 delivers a smooth warm sound reminiscent of older vintage gear. The Eclipse ET-DB3 transformer is magical in its ability to handle extreme signal levels with a natural compression that is pleasing to the ears. The transformer also helps eliminate hum and buzz caused by ground loops by isolating the input from the output. This is augmented with a ground lift switch that lifts pin-1 on the XLR for quiet, professional results.

FEATURES

PAD
Reduces the input sensitivity by 15dB for louder instruments such as an active bass guitar or keyboard so that they can be used without distortion.

Input
Unbalanced hi-Z input connection for your guitar or bass.

Thru
Direct output connects the instrument to the on-stage amplifier.

Output
Sends the lo-Z balanced output signal to the PA system or audio workstation.

Ground
Lifts pin-1 at XLR to reduce hum and buzz caused by ground loops.
