Gettingstarted
•IfyoucanbuildtheLushOne basemodulethenthen
buildingtheEchoshouldbeeasy
•Remember:
–Accuracyandneatnessismoreimportantthanspeed
•Getitworkingfirsttime
–TheseinstructionswillguideyoubutIassumeyouare
familiarwithbasictechniquesandequipment
•Allcomponentsexceptthepower‐inaremountedon
thecircuitboard–noslow,fiddlypointtopointwiring!

Patchsockets
•9smallsilverpatchsocketsfitfrom
frontofboard
•Fitinthelarge,labelledcircles
–Notthefourmountingholesinthe
extremecorners
•Solderroundrimonback
•Suggestyoufitfirstsoyoucan
makethemsitnicelyflushwiththe
board

ICs
•AllICsaremountedfromtheback
•ICsareprovidedunsocketed
–Youcanaddsocketsifyoulike!
•Positionsandorientationsaremarkedonthesilk‐screen
–Pin1alsohasasquarepad
•Thevoltageregulatorhasthesamecaseasthetransistors–checkthe
labels!
