Thebuilt-inUSBinterfaceallowsforsome
powerfulandexiblerouting.Itisa4x2interface
allowingyoutorecorduptofourstreamsfromthe
mixer,ortoinputstereoplaybackfromacomputer
androuteittonearlyanyoutputorpairofoutputs
onthemixer.TousethisfeaturewithaPC,rst
download the PC ASIO driver from www.720trees.com.
IfconnectingtoaMac,themixerwillshowupasa
4x2devicewithnodriverrequired.
TheUSBroutingcapabilitiesareasfollows:
USB input TO the mixer - playback:
(1)Stereochannel23/24(onthe2404VLZ4)and
31/32(onthe3204VLZ4)featuresaUSBbutton,soone
mayroutecomputeroutput(suchasiTunes

)downthe
last stereo channel of the board. This stereo signal may
thenbeEQ'd,senttoauxiliaries(i.e.tofeedmonitors,
headphonesoreffects)andisroutabletomainsand/or
subgroupsviathefaderroutingfeaturesthatare
available on all other channels. In short, this signal may
besenttonearlyanydesiredoutputorpairofoutputs.
Additionally,thegainknobatthetopofthischannel
stripadjuststheUSBinputleveltothemixertoachieve
anoptimalsignallevel.

necessary.
USB output FROM the mixer - recording, etc:
(1)Avarietyofdifferentsignalsmayberecorded
viatheUSBoutputsection,dependingonthesetup.In
the'USBOUT'section,theswitchontheleft[51]will
selecteitherGroups1-2orthemainmixtofeedUSB
outputchannels1-2.Thesecondswitch(totheright)
willselecteitherGroups3-4orAux5-6tofeedUSB
outputchannels3-4.
Forexample,withbothUSBouputswitchesinthe
defaultposition(up),true4-trackrecordingmaybe
accomplishedviaroutingtosubgroups1-4.TheUSBtap
pointsforthesubgroupsarepre-fader(alsopre-insert)
andpost-compressor.Thesignalswillshowuponthe
DAWdependentuponhowtheyarepannedonthe
channels.
Inotherwords,ifsubgroups1and2areusedtosub-
mixdrumsandthosedrumshaveastereoimage
(e.g.overheadsandtomspanaccordingtodesire),this
stereoimageisretainedintheDAWinputs(assuming
subgroup1issetto“L”andsubgroup2issetto“R”).
Anyadjustmentsmadetothesubgroupdrumlevels
duringtheshowonlypertaintotheliveshowitself;
recordinglevelsarenotadjustedintheDAWunlessthey
areadjustedonthechannels.However,compression
settingsmadeonthemixerwillapplytotherecording.
Likewise,itispossibletorecordthemainmixtotake
homeacopyoftheliveshow.Theselevelsarealso
pre-mainfader.Therefore,levelsmaybemixedupor
downintheDAWlaterdependingontheneedsofthe
recordingversustheliveshow.Theendresultisthat
fade-insand/orfade-outsmadeduringtheshowdonot
affect recorded levels.
Andnally,itispossibletoroutetheaux5-6(again,
pre-fader)mixersignalsintoaDAWorplug-inhost.
Fromthere,re-routetheoutputoftheDAW(orplug-in
