Appendix “B”
Input Sensitivity
Jumpers 101 and 102 on the standard input module’s PCB are used to set the Input Sensitivity of the amplifier for each channel or zone. The output level of the input source determines the setting. Since, each channel or zone may have a different input source, it is acceptable to have these jumpers set differently according to the potential output level of the input source. The figure below show the correct jumper setting for an input sensitivity of 0.775VRMS or 1.5VRMS.
Caution! Before removing the module to change input sensitivity or to set Bridged Mono, Parallel Mono or Normal operating modes, make certain that the amplifier’s AC mains are first switched OFF.
Bridged, Parallel, Normal Settings
Jumper 100 on the standard input module’s PCB is used to configure the Standard Input Module and the amplifier in which it resides to operate in Normal, Bridged Mono or Parallel Mono modes. It is imperative that the module be configured to the operational mode desired before making the loudspeaker connections. Configuration of the jumpers should only be done with the amplifier’s power OFF. The figure below shows the correct jumper placement for each of the three modes of operation.
Bridged Parallel
Mono Mono Normal
JP100
CONFIGURATION
Caution! Before removing the module to change input sensitivity or to set Bridged Mono, Parallel Mono or Normal operating modes, make certain that the amplifier’s AC mains are first switched OFF.
