Turning up the volume for the current amplifier will cause other inputs assigned to that amp to play louder when they become active.
  • Page 13 5003-01.QXD 8/14/00 4:46 PM Page 13 Quick Start To Select a Specific Input The amplifier is normally set to monitor input activity and, based on the default or installer-created priority table, automatically switches the proper input for each channel. You can override the priority switching feature of any amp to select a specific input to be on continuously.

  • Page 14: Aux Input Trim Adjustment

    5003-01.QXD 8/14/00 4:46 PM Page 14 Quick Start Aux Input Trim Adjustment By adjusting the Trim controls as follows, inputs with different signal levels are set approximately equal within the amplifier. Important: You must properly set the Aux Input Trim Controls. Improperly adjusted trims can result in high distortion levels, poor volume balance between different inputs and false trigger- ing of inputs.

This is because the levels set by the user are temporary and the PM-3180 always strives to maintain volume differ- ences set by the preset programming. Typically, this will only occur when the inputs or limits are set vastly different for the inputs assigned to an amp channel.
