ThePhoenixaudioconnectorsareelectronicallybalanced. Each input containsthreepins:
Signal+, Signal- and Shield.Dependingon themodelmorethanonechannelmightbe
combined on thePhoenixconnector.

2.6. Balanced &unbalanced Inputs
Theamplifier maybeoperatedwith unbalancedor balancedlines.For optimumperformanceuse
balancedlineswheneverpossible.
Thedrivingdeviceshould beequippedwithabalancedoutput.
Nevertheless,shortcablesinsidearackarenotthatcritical.In thesecasesunbalanced cables
maybeused.
2.7. Earth/ShieldingBASICXBXV
Thechassisground oftheamplifierisconnectedwiththeground oftheAC powercord(thenon-
fused earthed protectiveconductor).
Therefore,ifseveraldevicesareconnectedinasignal chainaground loopmaybecreated.
Thisgroundloopwill causeacompensatingcurrenttotravelon theshieldsoftheaudiocables
causinghum-problems.
The GROUNDLIFT switch onthebacksideoftheunitwillisolatethechassisgroundfromthe
signal ground andinterrupttheflowofthecompensatingcurrent.
Thisisanaccepted andwell-proven methodto suppress signal hum.
IsolatingthegroundoftheACpower cord istechnicallydifferentand eliminatesthe
protectiveearthconnection. Therefore, NEVER isolatetheground oftheAC power asthis
mayposeaseriousdangertoyourlife.
