MIXTRIM and MIXMODE
WhensettotheSWITCHED(dualchannelmode),
specialoptionsareavailabletoallowtheaudiofromthe
receiverstobemixedtoeitheroneorbothaudiooutput
channels.
The MIXMODE setting determines which audio signal
appearsatwhichoutputchannel:
• MIXBOTH mixes the audio and delivers the mix to
bothoutputchannels.
• MIXTO 1 mixes the audio and delivers the mix to
outputchannel1.
• MIXTO 2 mixes the audio and delivers the mix to
outputchannel2.
• DIRECTkeepstheaudioseparatedanddelivers
receiver1audiotooutputchannel1,andreceiver2
audiotooutputchannel2.
The MIXTRIMsettingappliesattenuationupto20dBin
1dBstepstoadjusttheratioofthetwoaudiosignalsin
themix.Thisadjustmenttakeseffectonlywhenamix
mode is selected (it is ignored when the mix mode is
settoDIRECT).
IMPORTANT:Theoutputlevelofeachreceiver
isadjustedwiththeLEVELsetupscreen,which
ishardware-based,soitaffectstheoutput
level regardless of which mix mode is selected.
MIXTRIMthenappliesattenuationtothatlevel
settingresultinginthenalleveldeliveredto
theoutputchannel.Itisgoodpracticetoset the
output level of both receivers to the same
value when using a mix mode.
WhenaMIXMODEisselected,eachaudiosignalisau-
tomaticallyattenuatedby6dBpriortothemixing.This
isdonetoavoidoverloadandpotentialdistortionsince

receiver.
