Midi Solutions MultiVoltage Thru - Introduction to MIDI Solutions MultiVoltage Thru; Product Overview; Connecting the MIDI Solutions MultiVoltage Thru; Wiring Diagram and Recommendations

ThankyouforpurchasingtheMIDISolutionsMultiVoltageThru.
TheMIDISolutionsMultiVoltageThruprovidestwoMIDIThruoutputsfromoneMIDIinput,allowingadditionalMIDIoutputsto
beaddedatanypointintheMIDIchain.Activecircuitrycleansupanyskewingofthedatabitsthathasoccurredattheinput,
resultinginaccurateoutputsignals.TheMIDISolutionsMultiVoltageThruisMIDI-poweredandrequiresnobatteriesorpower
supplytooperate.Itiscompatiblewithproductsthatfollowboththe5Vand3.3VMIDIspecifications.

ofthe ThrutotheMIDIInsofthereceivingMIDIdevices.ThenumberofMIDISolutionsproductsthat
canbechainedtogetherisdependentonthespecificationsoftheMIDIoutputportsupplyingpower–formoreinformation
seetheMIDIINDICATORLEDsection.Sincesomeproductsmakeuseofunusedpins1and3topassphantompower,
connectionstothesepinsareprovidedbetweentheMIDI and jacks.Thesepinsarenotconnectedtothe
Thru'sinternalcircuitry.Itisrecommendedthatthecurrentpassingthoughthesepinsbelimitedto1amp.
AllMIDImessagesappearingatthe Thru'sMIDIinputaresenttoitsMIDIThruoutputs and .
TheMIDIIndicatorLEDwilllightassoonasthesendingdeviceisturnedon,andflashesbrieflywheneverMIDIdatapasses
throughtheunit.Ifthe Thru'soperatingvoltagedropsbelowthethresholdatwhichitisabletoprovideaMIDI
standarddrivecurrentof5mA,itsLEDwillproduceasteadyon/offwarningflash.AfterrisingabovethisthresholdtheLED
willcontinuetoproduceasteadyon/dimflashfor10seconds.Sincethevoltagealwaysrisesabovethisthresholdonpower
up,asteadyon/dimflashwillalwaysbevisiblefor10seconds;duringthistimetheunitisoperatingnormallyandproviding
thestandarddrivecurrent.Ifthe Thru'soperatingvoltageisbelow4VitsLEDwillproduceadimflashevery
fourseconds,thissignalisfordiagnosticpurposesanddoesnotaffectitsoperation.
