Harman Kardon Avr 51 User Manual 134 Better Work <TRUSTED × 2025>

While there isn't a single combined manual for both the Harman/Kardon AVR-51

2.3 Speaker setup (critical – missing in original)

1. Press Test Tone on remote.
2. Use Channel Adjust buttons to match levels with an SPL meter (or by ear).
3. Speaker Size:

   Critical Information Found ONLY in the Manual:

   • Speaker阻抗配置: The AVR 51 expects 8-ohm speakers. Setting it wrong triggers protection mode.
   • Logic 7 Modes: The manual explains when to use Cinema vs. Music mode for stereo sources.
   • OSD (On-Screen Display) Activation: You must press the “OSD” button then “Adjust” – a sequence not intuitive without the guide.
   • EZSET/EZSET+ Calibration: The manual outlines the microphone placement rules for the auto-EQ system.
   • “Large” = full-range (rare). “Small” = better for satellites + sub.
   • If “Subwoofer” = YES → set all others to SMALL.
