thatproducesheat.
6. WARNING–THISAPPARATUSMUSTBEEARTHED/GROUNDED.
7. Onlypowercordswiththecorrectpowerconnectormaybeusedtomaintainsafety.Cablesincorporating
theUK13Afusedplug,SchukowithearthingcontactsandULapproved“groundingtype”areacceptable.
Thesemustbepluggedintopoweroutletswhichprovideaprotectiveearth.
8. Referallservicingtoqualiedpersonnel.Servicingisrequiredwhentheapparatushasbeendamagedin
anyway,suchasapowersupplycordorplugisdamaged,liquidhasbeenspilledorobjectshavefallen
intotheapparatus,theapparatushasbeenexposedtoanyrainormoisture,doesnotoperatenormally
orhasbeendropped.
9. WARNING–Toreducetheriskofreorelectricshock,donotexposethisapparatustorainor
moisture.Theapparatusshallnotbeexposedtodrippingorsplashingandnoobjectslledwith
liquids,suchasvases,shallbeplacedontheapparatus.
10. Warning:Connectiontoa100Vlinesystemmayinvolvetheriskofelectricshockandtherefore
mustbecarriedoutbyaninstructedorskilledperson.
2. TOOLS AND EQUIPMENT
Smallhandtoolsincludingawirestripper,smallatbladeandposiscrewdriverswillberequired.
Amagneticeldstrengthmeter,LoopworksMeasureApp&R1Reciever,oratminimumaninductionloop
receiverisvitaltocheckthattheloopsystemisprovidingthedesiredlevelofperformance.

4. SETTINGS
TheCSeriesdrivershavetheiradjustmentssetindecibels(dB).Asettingof0dBequatestomaximum
currentortomaximuminputgain.Anegativevaluewillreducethecurrentorinputgainaccordingly.
Fromthefactorythedriversareprovidedwiththefollowingsetting:
5. ADDITIONAL FEATURES
• Home screen timeout –ifnoactionistakeninamodescreenafter30sthehomescreenisdisplayed.
Foravaluescreenthetimeoutis60s.
• Sleep mode–Aftera10minuteperiodofuseroraudioinactivitythedriverturnsonthe‘Loopoutputs
disabled’testsignalandturnso󰀨thescreentosavepower.TheStatusledashesgreentoindicatethis.
Anyuseractivityorpresenceofaudiosignalbringsthedriveroutofsleep.Theinactivitytimecanbe
changedviathewebsite(wherenetworkoptiontted)
• Lock screen –Alongpressonthehomebuttonbringsupthelockmenu.Thisgivesaccesstostandby,
re-start(sameasinsettingsmenu)&lock.Selectinglockmakestheusercontrolsinactive.Anyuser

• Standby –Thisisauserimposedsleep.Onlyuseractivity(notaudiosignal)bringsthedriveroutof
standby.
3. INPUTS AND OUTPUTS
Thedriverhastwoinputslabelled1and2.Each
inputcanbeseparatelyconguredtomicorline
signallevelusingarearpanelpushswitch.Global
24Vphantompowercanbeenabledtosupply
anyinputsettomiclevel.Alternativelyinput2can
accepta100Vlineusingadedicated2pinsocket.
Do not use both input 2 sockets at the same
time.
 Warning:Connectiontoa100Vline
systemmayinvolvetheriskofelectricshock
andthereforemustbecarriedoutbyaninstructed
orskilledperson.
ThedriverhastwoloopoutputslabelledLoopA
andLoopB.Inordertoachievecorrectoperationit
isrecommendedtheloopandfeedresistance
shouldbebetween0.2and10Ω(atDC).
