Manufacturer's Description from Grace

Studio Quality 2 Channel Instrument & Mic Preamplifier / Blender / EQ

Felix is our new, 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.

Designed and built by family and friends in sunny Lyons, CO, USA.

About Manufacturer

Audio engineer/designer Michael Grace originally began building single order custom audio products for a small, devout following of recording engineers and artists is 1990. Before long, the word had spread about Michael's custom microphone preamplifier designs, which were said to outperform anything else that was commercially available. Based on an increasing demand for his mic preamp design, in 1994 Grace Design was founded and began production of the original 801 mic preamp. Not only did the 801 provide a new level of audio performance and functionality, it helped to establish outboard microphone preamplifiers and direct-to-tape recording as a new standard in professional audio production. Over the years, Grace Design has maintained a steady, methodical pace to developing new products and technologies. Our product line has evolved into a definitive collection of microphone preamplifier configurations and other unique professional audio products. While the professional audio industry is inundated with products seemingly designed for obsolescence, we pride ourselves on providing audio professionals with the finest tools imaginable. Located in Boulder, Colorado, Grace Design continues its mission into the new millennium. As our company grows, we continually strive to improve our production methods to make sure theya re exact, efficient and environmentally sound. Their employees are treated like family and they strive to improve our production mehods to make sure they are exact, efficient and environmentally sound. Our employees are treated like our family and we strive to maintain our business relationships as friendships. And above all, we remain driven by the original passion that founded the company- the love of music.
