FELiX is a studio quality, 2 channel blending acoustic instrument and mic preamp, designed for working
musicians, engineers, sound companies or venues looking for the highest quality solution for amplifying
stringed instruments. FELiX is built into a roadworthy (beer-resistant) floor unit chassis of anodized
aluminum and steel, portable enough to leave the rack at home but bring studio quality to the stage.
With the same stunning audio performance and legendary reliability as Grace Design’s pro audio range,
FELiX brings open, musical and nuanced preamplification to any performance situation.
A powerful eq section allows simple and intuitive tone shaping for even the most unruly of instruments.
Each channel’s variable high pass filter cuts 12dB per octave from 20Hz to 1kHz, and can also be set as a
notch filter for chasing down problem feedback or rumble areas. Parametric mid range controls cover
from 70Hz all the way to 8KHz. While fixed low and high controls are carefully voiced for musical shading
of bass and treble.
Controls are simple and clearly marked on a bright panel, making them easy to read and tweak on a dark
stage. Footswitch functions include a mute / tune switch for muting all outputs except the dedicated
tuner out, a boost switch which activates a variable boost circuit, and finally, an A/B mode switch for
when FELiX is in A/B mode (which simply toggles between the two different channels).
FELiX brings the kitchen sink approach to I/O. Inputs include a 48V XLR mic input and two instrument
inputs. Two independent transformer isolated DI outputs can be sourced from either the mix or the
individual channel. This allows you to send the front of house a mix or each channel independently. A
dedicated, level controlled amplifier output can be sourced from the mix or channel 2. A dedicated
tuner output stays active when all the other outputs are muted. A side panel mounted 1/8” mini jack
headphone amplifier is there for practicing, private noodling during boring soundchecks, or scrutinizing
dubious eq decisions. A TRS insert is included for adding effects, and finally, a remote footswitch jack is
included if FELiX is going to spend his life in a rack or up off the floor.
Guitar, bass, fiddle, mandolin, cello, dare we say banjo, that weird 3 string gourd thing – FELiX is your
instrument’s new best friend. Flexible, reliable, a good listener and eager to make you sound better, he
is also your new best friend.
