Tobetterhandlethehugeamountofparameters,thesinglevaluenumericinputmodeisextendedwithafine/coarse
feature.Whenyoueditoneoftheparameters,youwillstartinthe“fine”mode. Thestepsappliedbythe-and+keys
aretheminimumallowableforthatparameter.Byclickingthe“fast”keyshowninfigure2.3.3,youwillswitchinthe
“coarse”mode,andthekeywillberenamedas“slow”asshowninfigure2.3.4.Inthecoarsemode,thestepsare
equivalentto10stepsofthefinemode,sothateditingwillbe10timesfaster.Rememberthatbykeepingthe-or+
keypressed,thestepsareautomaticallyrepeated.

2.3.1Outputattenuation
Thefigure2.3.5showstheOutputattenuationscreen. YoucanchoosetosetCH1,CH2orbothbypushingthe"C1+2"
button. The"+"and"-"buttonschangethevalueoftheoutputattenuationintherangefrom0to-30dB.
Note:forthebestsonicperformanceitispreferredtosetthe0dboutputattenuation(noattenuation),and
selectthepropergain/sensitivitybythefollowingmenu.
