1642VLZ4,youcanpatchanythingalmostanywhere,
withnaryacare.Here’swhy:
• Everyinputandoutputisbalanced(except
inserts,phonesandRCAjacks).
• Everyinputandoutputwillalsoaccept
unbalancedlines(exceptXLRjacks).
• Everyinputisdesignedtoacceptvirtuallyany
outputimpedance.
• Themainleftandrightmixoutputscandeliver

Phantom Power
Mostmodernprofessionalcondensermicsare
equippedforphantompower,whichletsthemixer
sendlow-currentDCvoltagetothemic’selectronics
throughthesamewiresthatcarryaudio.(Semi-pro
condensermicsoftenhavebatteriestoaccomplishthe
samething.)“Phantom”owesitsnametoanabilityto
be“unseen”bydynamicmics(ShureSM57/SM58,for
instance),whichdon’tneedexternalpowerandaren’t
