Ϯ͘ϲ.1 MI715

TheMI715’sSampleRateissetexternallybyoneoftwosourcesignalsorinternallyby

crystalsandassociatedcircuitry.TheSampleRateSourceisdeterminedautomatically

bythepresenceofsignalswhentheMI715ispoweredon.Theorderinwhichexternal

signalsaretestedforpresenceis:AES,Word,Internal.

ThedetectedsignalimmediatelybecomesthesourcefortheMI715’ssamplerate

clock.Theauto‐sensedSampleRateSourcecanbeoverriddenusingthebuttononthe

frontpaneloftheMI715,belowtheSampleRateSourceLEDs.IfneitherAESnorWord

Clocksignalsarepresent,theMI715usesitsinternalclockderivedfromon‐boardvolt‐

age‐controlledcrystal.

ThedefaultinternalSampleRateoftheMI715is48kHz.Thisdefaultinternalratecan

beoverriddenwiththeSampleRatebuttononthefrontpaneloftheMI715(directly

Ϯ͘ϲ.2 MO705

followingtwodifferences:

• SincetheMO705isalwaysaslavetoanexternalSampleRateSource,thereis

nointernalSampleRatesetting.

•TheMO705canuseMADIinadditiontoAESorWordClockasaSampleRate

Source,anddetectsthepresenceofthesesignalsinthefollowingorder:AES,

Word,MADI.

Whenasignalisdetected,itimmediatelybecomesthesamplerateclockofthe
