MTX Quick start guide
This chapter guides you through the setup process of a basic project with one MTX audio
matrix and 8 standard MWX43/45 wall panels, two All-In-One MWX65 wall panels and some
regular Line & Microphone input sources.
Overview of the MTX setup
Connecting the MTX
ATTENTION
MakesurethepowerofthedeviceisturnedOFFbeforeanyconnectionsorwiring
adjustmentsaremade.Whendisregardingthisrule,itcanleadtopermanentdamageof
theequipment
1) Connecting audio sources
ConnectalltheMicrophonestotheXLRconnectorsontherearsideoftheMTX.When
usingcondensermicrophones,makesurethephantompowerswitchisturnedON.
ConnectalltheLine-Levelaudiosources(CD-Players,MP3Players,Tuners,...)tothe
RCAconnectorsontherearsideoftheMTX.Adjustallinputgainstotheappropriatelevel
sonoinputclippingoccurs.
2) Connecting amplifiers and/or speakers
Connectamplifiers(100VorLowimpedance)tothebalancedoutputsoftheMTX(Three-
pinEuro-TerminalBlock).Theamplifierconfiguration(100VorLowimpedance)andpower
needstobechosenaccordingtotherequirementsforeachspecificapplication.Inits
