Grace Design Bix - Single Channel Instrument Preamplifier

Grace Design Bix - Single Channel Instrument Preamplifier

Acoustic Instrument Preamp, EQ, DI and Boost 

BiX shares the exact same DNA of its bigger siblings FELIX and ALiX, but with an intelligently streamlined feature set and a price that puts it in reach of any performer, whether on their way to the local coffee shop or the megadome.

Controls are dead simple – input gain, high and low shelving EQ, and a 10dB variable boost circuit, with footswitches for mute and boost. I/O includes the instrument input, separate send and return insert jacks, an unbalanced line output, and a balanced ISO DI output on XLR. For enhanced EQ control, rear panel DIP switches select between two different transition frequencies for both High and Low controls. And BiX is pedalboard friendly, with a 9VDC power input and a compact, rugged low-profile chassis.

Sonically, BiX is a carbon copy of its bigger siblings, with crystal clear, ultra-quiet audio performance. A better than 30VDC internal operating voltage provides for incredible headroom. The highs are smooth and open, and the lows are deep and rock solid. The dynamics and tone of the instrument come alive with clarity and realism, which translates to creating a deeper bond between you and your instrument.
