Power on system; configure with AV receiver.

  1. Set receiver speaker settings: Configure for "Small" speakers with crossover at 80-100Hz.
  2. Calibrate levels: Use receiver's auto-setup or manual test tones to balance speaker volumes.
  3. Test audio: Play content to verify all channels are working correctly.
  4. Fine-tune placement: Adjust speaker positions for optimal soundstage.

CAUTION! Ensure all connections are secure before powering on. Keep cables away from heat sources.

Specifications
