Introduction

TheCrescendopre‐amplifierassystemconsistsofseparateinterconnectedparts:
Crescendopre‐amplifierfirmware,craftware
iTouchremotecontrolappletsoftware
ViolaDACfirmware,driverandcraftware.
CrescendoreceivesitscommandsfromtheiTouchremotecontrolappletthroughadecicatedTcp/IP
portinaWi‐Finetwork.WhenthesecommandsaremeantfortheViolaDAC,itpassesthemalongan
internallocalbus.StatusandtelemetrydataispolledfromtheCrescendo’ssubsystemandpushedonto
theiTouch.
Crescendocraftwareisusedtosetthesystemup(network/wifisettings)orsetupfeaturesyouwould
notwanttogivetheremotecontrolappletaccessto(likeforinstanceSSPsettings).
DACcraftwareisusedtoupdatethefirmwaretotheDACwhennecessary.Itisincludedwithfuture
firmwarereleases.


TheCrescendocancommunicateonmostWi‐Finetworks.
Thefactorydefaultsettingcommunicatesonasocalled“ad‐hoc”or“pointtopoint”network,where
thereisnorouterorswitchbetweentheCrescendoandiTouch.
Mosthomenetworksconsistofawireless/wiredrouterthatseveralPCshookinto.Typically,anetwork
likethathasinternetaccess.WhiletheCrescendodoesnotneedtohaveaccesstotheinternet,most
usersfinditconvenienttogivetheiTouchusedforCrescendo’sremotecontrolalsoaccesstothe
internet.Todothis,theCrescendoneedstohaveaccesstoyourhomenetwork.
Thefollowingdiscussionwillguideyouthroughthesetupofeithernetwork.

Shouldthecrescendoeverneedtoberesettoitsfactorynetworksettings,findtheCresConf.exeutility,

ForasimplestaticIPnetwork,
leaveallsettingsalone.Sinceyou
aretheonlyoneonthenetwork,
theSSIDof“crescendo”andthe
devicenameof“CRESCENDO01”
willdojustfine
Selectthe“Update”checkboxes
for“WiFi”and“Network”.
DonotchecktheSSPcheckbox.
PressDone.


Tomakethesechangespermanent,performtheactionsindicatedbythesubheading“making
changespermanent”.


ThecrescendoisabletoprovideanIPaddresstoaconnectediTouchinasimplepointtopointnetwork
only.Todothis,changethesettinginthenetworktabtoDHCPlikeso:

ItisassumedthattheWi‐Fi’sSSIDhasbeenset
to“Crescendo”,aswasdoneabove.

WhenselectingDHCP,theblurbnexttothe
radioboxchangesto“DHCPServer”,indicating
thattheCrescendowillberunningaDHCP
server.

TheIPaddressandrelatedsettingswillbe
selectedforyou.TheCrescendoreservesthe
address10.0.0.1foritself.TheiTouchwillgetits
addressfromtheCrescendoafteritconnects.
Notethatthismodeisonlyavailableapointto
pointnetworkandonlyonCrescendosloaded
withversion1.0.1.11orabove.

Makingchangespermanent
ToconveyanychangestotheCrescendoPre‐
Amplifier,besurethattheappropriate
checkboxes(Wifi,NetworkorSSP)hasbeen
checkedpriortopressingthe“Done”button.
Forexample:
Ifyourcrescendohasbeensetupforyour
wifinetwork’sSSIDbutallyouwanttocheck
isitsnetwork’ssetup,itwouldbe
appropriatetoonlycheck‘network’without
checkingthe‘wifi’checkbox.
Ontheotherhand,Ifthisisthefirsttime
you’vesetupaunit,itwouldbeappropriate
toselectboth‘network’and‘wifi”.


Powertheunitdown.
powerupbackup
InserttheUSBkeyintheportlocatedinthebackoftheunit.Notethatthepre‐amplifierautomatically
rebootsafterthekeyisinserted.Thisisnormalbehavior.
AftertheCrescendofrompanelstopsflashing,removetheutilityUSBkeyfromtheUSBkey.
Yourcrescendoisnowsetup.
