9Bridged operationWhen greater power output is desired, the Nº23.5 may be bridged formonophonic operation into load impedances of at least 2Ω.Note: Make sure the loudspeaker is rated to handle extremelyhigh power levels. For example, a bridged Nº23.5 driving an 8Ωloudspeaker is capable of delivering 800W RMS.For the best bridged performance, we recommend balancedinterconnection. If your preamplifier provides balanced output, followthe steps below.Balanced bridgedoperationPUSHPUSH– +Loudspeaker+ –Nº23.5– +From preamplifierbalanced main outputBalancedbridging cableRightchannelLeftchannelFigure 9: Connections forbalanced bridgedoperation1.
