The Sound of Fractal Audio

Legen­dary Amp Modeling and Speaker Simula­tion
plus a Suite of Incre­dible Stompbox and Studio Effects

The FM3 fea­tures our la­test ARES Amp Mode­ling—a tech­nology developed by Fractal Audio for the award-winning Axe-Fx III. It captures the sound — and the equally important feel — of real tube amps, with 265+ models offering an imp­res­sive ran­ge of clean tones, elusive “edge of break­up”, and every­thing from warm, touch-sen­sitive over­drive to face-melting modern distortion.

The FM3 also inc­ludes the entire spea­ker cab im­pulse re­sponse (“IR”) collection from the Axe-Fx III, with a stunning 2,200+ “Factory” choices and 1,024 “User” locations to store custom sounds from free or commercial producers.

As a mul­ti-effects unit, the FM3 truly ex­cels. It inclu­des a superb selec­tion of Fractal Audio’s sta­te-of-the-art effect algorithms. All of the essentials and many exciting innovations are on board: dazzling drive pedals, dozens of delays, re­verbs, compres­sors, EQs, phasers, flan­gers and other modu­lation effects, a loo­per, and much more.

Impres­sive USB Audio Capabi­lities

Play­back, Record, Re-Amp

With a USB con­nec­tion to a Mac or PC, the FM3 works as an extre­mely high qua­lity 4×4 audio inter­face for play­back, recor­ding, and re-amping. This lets the FM3 doub­le as the hub of a por­table recor­ding studio.

USB chan­nels are mapped for maxi­mum ease of use. For examp­le, to record the pro­ces­sed stereo out­put of the FM3, just record in­puts 1 and 2 in the com­puter. Compu­ter in­puts 3 and 4 can be used to cap­ture a DI, or to re­cord input 2 L+R in ste­reo.

Compu­ter play­back is also easy and fle­xible. For stu­dio work, you can mix a pro­ject and the FM3 to a sin­gle pair of con­nected moni­tors and tran­smit a sepa­rate DI to the FM3 for re-amping. For live per­forman­ces, you can route the ste­reo FM3 and ste­reo backing tracks to different stereo outputs.

USB also al­lows 2-way com­muni­cation bet­ween the FM3 and its com­panion soft­ware appli­cations, FM3-Edit and Fra­ctal-Bot.

fm3 3 4A Rugged Floor Unit

The FM3 is housed in a du­rab­le steel chassis with pro­tecti­ve endcaps desig­ned to with­stand the ri­gors of tou­ring.

Three on­board foot­switches – each with va­riab­le-color LED ring and mini LCD dis­play — pro­vide both tap and hold func­tions, which can be custo­mized to do dif­ferent things on eight dif­ferent switch “layouts.” The new “Views” fea­ture multi­plies the po­wer of layouts, in ef­fect crea­ting a virtual 12-button cont­rol­ler with a 3-but­ton foot­print.

In ad­dition, a FASL­INK II port al­lows the FM3 to be con­nec­ted with up to two Frac­tal Audio FC-12 or FC-6 foot cont­rolvlers, pro­viding an exci­ting array of exten­ded cont­rol op­tions.

While desig­ned as a floor unit, the FM3 fea­tures an intui­tive hands-on inter­face with the same full-color dis­play and fami­liar, easy-to-use front pa­nel cont­rols found on the Axe-Fx III.

The unit is po­wered by a 3-Core “Grif­fin” DSP with one ARM and two SHARC+ cores pro­viding supe­rior power in a com­pact format. A de­dicated graphics pro­ces­sor allows the main DSPs to be fo­cused on cri­tical audio tasks.
