Manufacturer's Description from Grace

FELiX2 NEW FEATURES INCLUDE:

STEREO OPERATION

New dual mono or true stereo FX loop allows for independent FX loops on either channel or stereo FX operation with mono or stereo in

Stereo amp output for connecting to stereo stage amp rig

Stereo headphone output for stereo headphone personal monitoring bliss

 

VARIABLE PHASE CONTROL

Built in variable phase control on channel 2 allows users to adjust mic / pickup blending systems to be perfectly phase coherent

 

MORE EQ POWER

HIGH shelving EQ control updated to include 2 transition frequency settings at 1k and 2k, allowing for more flexible high frequency tone control

New notch filter uses a much higher Q setting for better surgical control of problem frequencies

 

NEW POWER SUPPLY

Class II power supply eliminates ground loops when connecting to stage amps and other non-isolated stage equipment

NOTE: this is now a 2 prong power input

 

BETTER STAGE MANNERS

New protective side rails and slightly lower profile knobs to help protect controls from extra left feet and floppy stray instrument cables

 

CHANNEL 1 BOOST DEFEAT

Allows the boost circuit to only affect channel 2

FELiX2 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. FELiX2 is built into a roadworthy 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, FELiX2 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.

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.
