BiX
Acoustic Instrument Preamp, EQ, DI and Boost
“Stoked to be using the Grace Design BiX. This thing sounds natural and full. It’s very responsive and catches all the little nuances that I love about my acoustic guitar.”
– Billy Strings
In a few short years, FELiX and AliX have become the preamps of choice for discerning touring and recording musicians. From Banjo to bass players, they enable performers to perfect their stage and studio sound beyond what was previously possible.
And now directly from this lineage comes BiX, which shares the exact same DNA of its bigger siblings, 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.
