APPENDIX B (CONT.):
Input Sensitivity Level Setting Reference Listings
Step 1: Define your front/rear channel configuration (Stereo/Stereo, Stereo/Bridged or Bridged/Bridged
Step 2: Look in the “Optimum Configurations” listing for your channel configuration. If it does not appear here,
look for it in the “Sub-Optimum Configurations” listing for your channel configuration.
Step 3: Once you have found your specific combination of impedances, use the target voltage listed in
parentheses for each set of channels to set the “Input Sens.” controls of the 300/4.
For easy reference, channels achieving optimum power have their power output listed in bold type.
