- 1 - INTRODUCTI ON Thank you for purc hasing a Quadra/FX a nd congratu latio ns! You n ow ow n one of the m ost sophis ticated pieces of audio signa l-proces sing tech nolog y availab le.
- 2 - QUICK ST ART INSTR UCTIONS You’ve unpack ed your Quadr a/F X and you’r e in a hurry to get it up and running. You pro bab l y would r ath er play wit h i t than read the manua l. Fair enoug h. First, check out the bas ics, ou tlined h ere, jus t to get your Qua dra/FX on- line.
- 3 - board and not ad ditional ly at the Qu adra/FX ’s fader s. On e way to d o th is is to set EACH preset ’s M ix param eter to 100%. T his would be a te dious proc ess! Fortunatel y, there is a sp ecial Q uadra/FX function called Dr y Kill that wil l convenient ly turn off the dry signal p ath inside the u nit.
- 4 - Output #2 t o the am p’s other ef fects return jack .) Again, do n’t f orget that the Q uadra/FX has the po wer to ac t as two sep arate, s tereo pr ocessor s or four separat e, mono pr ocess ors. TRY IT OUT: Turn on your am p or m ixer and m onitor am plif ier.
- 5 - INSTALLATION The Quadr a/FX m ay be used i n a variet y of setu ps includ ing wit h m ixer c hannel ins erts, m ixer s with r everb s end an d return f aciliti es, and i n the ef fect s loop of an instr um ent or P.
- 6 - QUADR A /F X FRONT P A NE L CONTR OLS & INDIC A TORS - ROT ARY ENCODER / SWITCH The Rotar y Encoder is us ed to cha nge va lues or pr esets. D epend ing on the Quadr a/FX ’s programm ing m ode, it m ay also be press ed to chan ge m enus.
- 7 - & ENGINE BUTTON The Quadra/FX contains up to four audio s ignal pr ocessor s, or engin es. Pres sing th is button and turni ng the Encod er will s elect an eng ine for editing ( the selec ted eng ine LED will flash). Depe nding on the current rout ing, one or more engine L EDs may flash.
- 8 - ) P A RAMETER BUTTON W hen you press the Parameter button, the LEDs for all a vaila ble param eters of the current en gine’s eff ect are lit. The cur rentl y selected param eter LED flas hes and its value is dis played in the Preset / Valu e window.
- 9 - Display show s for a bypas sed eng ine and for a b ypass ed preset. Pr ess Bypass aga in to disengag e this m ode. W hen B ypass is pr essed i n Preset mode, al l eng ines are b ypassed. W hen Bypass is engaged while edit ing an engin e, onl y the curr ent eng ine is bypass ed.
- 10 - If you hav e made som e favorite program s, either sc roll through t heir param eters and wr ite them down, or use the MIDI D ump f eature to off-load your presets to a MIDI storage devic e b efore implem enting a factor y res et. (See pag e 12 for inform ation on the Qu adra/FX ’s MIDI D um p.
- 11 - NOTE: W ith Dry Kill active, a preset’s Mix par ameter now sets th e level of al l sound c oming ou t of the Quadra/FX . For example, with a Mix s ettin g of 0, no s ound will com e out of the unit (i n other words, zero percent of the wet signal is allowe d to pass) .
- 12 - MIDI Dump By perform ing a MIDI Dump, you can save all of the Quadr a/FX’s pr esets to an exter nal dev ice capab le of recording MIDI da ta. You c an even dir ectl y transfer the presets f rom one Quadra/F X to an other on e with a MIDI cable.
- 13 - QUADR A /F X REAR P A NEL CONTROLS & C ONNECTIONS Despite th e Q ua dra/F X ’s s oph is tic at io n, it is e as y to inter f ac e th e un it wit h ot her equ i pm ent. Al l inputs an d o utpu ts ar e located o n the rear panel. Standar d ¼” inp uts an d outputs m ake patching sim ple.

- 15 - TUTORI AL The bes t way to unders tand the Qua dra/FX is to jus t jump in a nd edit som e presets. It does n’t take long and you’ll see how eas y edit ing is d ue to the Q uadra/F X’s i ntuiti ve la yout. T his sectio n cons ists of four tutorials : Creating Fr om Scratc h, J ust Edit ing , MIDI , and Advanc ed App licatio n Notes .
- 16 - Cascad e Cascade ro uting also has two process ors with two linked engines, but the outp ut of th e first pr ocessor is fed in to the secon d one. In th is rout ing, you have t wo stack ed, true-ster eo effec ts. Onl y Inputs an d Outputs #1 and # 2 are used.
- 17 - Engine button to enable routing changes. If you press any other but ton inste ad, the old rout ing wil l be restored. NOTE: Pann er and Ro tar y are stere o effec ts and are not avai lable in Discr ete 4 (m ono) routin g.
- 18 - Param eter button a gain. Al l Param eter LEDs go o ut exce pt for the one that was flash ing (t he o ne you selected). T urning the Enc oder will now c hange t he param eter’s value, as can be seen in the Preset / V alue Display.
- 19 - all active in puts. (For mor e inform ation on the Smart Meter, s ee page 9.) The LED to the f ar lef t shows the current preset ’s r out ing. Mak e sure th e selec ted pr es et ’s rout ing is on e th at c an be m onit ored with your s etu p.
- 20 - procedure to e dit as m an y param eters as you want. W hen you are don e, you can s a ve the pr es et by pres s ing Store, s electing a pres et num ber to over write, an d press ing Store again to confir m. After you’ve edi ted one engi ne’s param eters , you m a y wish to edit another eng ine’s.
- 21 - Editing MIDI Parameters: To edit th e Quadra/FX ’s MIDI p aram eters, press the MIDI b utton. No tice that all of the Sm art Meter LEDs are l it and its MIDI Map/- 18 LED is f lashing.
- 22 - NOTE: MIDI m ap c an be set a nd change d from within an y engin e and it, along with the MIDI contro ller assignm ents (s ee the next s ection), n eed to be save d with t he pres et.
- 23 - To as sign MIDI to tr igger an engin e’s Sm art Enc oder func tion, tur n the Enc oder until two Param eter L EDs light. If on l y one Param eter light goes on at a tim e, it is b ecause t here is no Sm art Encod er f unction a vaila ble for the ef fect of the curr ent engine.
- 24 - Preset m ode and th e MIDI e dits wil l not be s aved, though the y will rem ain ac tive until you chan ge pr esets. MIDI Chan nel, ho wever, is autom aticall y saved each tim e it is updated .
- 25 - To tap in a new delay tim e, press the Encod er at the desire d tempo. T he num ber of times that you press doesn’t m atter; the Q uadra /FX tak es the a verag e tem po. As you are t ap pin g, you will h e ar the ne w de la y tim e and see its value in the Displa y.
- 26 - trigger the Sm art Encoder ’s stored actio n. Each preset can have one defau lt func tion and it bec omes active as soon as t he pr eset is lo aded.
- 27 - THE QUADR A /FX’s A DJ USTABLE PAR A METE RS DESCRIPTION OF ROUTINGS AND ENGINES The Quadra/FX contains four engines that can be routed in four diff erent ways.
