Singer / songwriters in search of a studio-quality acoustic instrument and microphone preamp will be thrilled with the Grace Design FELiX2, a 2-channel preamp and EQ with blend control, intended for amplifying stringed instruments and microphones. Housed in a portable, black floor-unit chassis made from anodized aluminum and steel, FELiX2 delivers a high-quality, yet rugged preamplification solution to musicians, engineers, studios, rental companies, and venues.

Version 2 adds numerous updates and features, including stereo operation, variable phase control, more EQ power, a new power supply, protective side rails, and a channel 1 boost / defeat. The FELiX2's EQ section allows simple and intuitive tone shaping. Each channel features a high variable pass filter that cuts 12 dB per octave from 20 Hz to 1 kHz that also can be set as a notch filter for surgical problem correction. Both channels also have parametric midrange controls that cover from 70 Hz all the way to 8 kHz, while fixed low and high controls are carefully voiced for musical shading of bass and treble.

• 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

Q: 9. Hi I have apollo twin x (Quad) and i have buy preamp GRACE m101 . Should I have Converter between these two equipment? If yes What is it the best converter for voiceover and for this equipment??

A: A converter is not necessary. Simply come out of the 1/4-inch TRS balanced output to the 1/4-inch portion of the combo input of the Apollo Twin X Quad. It is important to send the signal into the Apollo as a line level signal, to take advantage of the Grace preamp.. A Pearstone PM-TRS 1/4" TRS Male to 1/4" TRS Male Interconnect Cable (6'),BH #PEPMTRS06 would be a good choice for a balanced cable.
