2. Connections & Compatibility: This amplifier only supports RCA input, not Bluetooth. It’s incompatible with subwoofers and can only connect to a pair of passive speakers or bass shakers, not four speakers. The terminating impedance supports 2 – 8Ω.

3. Accessories & Dimensions: The package includes only a 32V 5A power adapter, no other cables. The product dimensions are 5.59×4.13×1.38in.

II. Sound – Related Solutions

1. Volume & Cable Issues: Set the volume to 50% or below to reduce noise. Check all cables are properly connected and undamaged.

III. Audio Quality Enhancement

1. Audio Sources & Setup: Use high – quality audio files like FLAC or WAV. Place speakers at least 30cm away from walls/corners and use rugs or curtains to reduce echoes. 2. Personal Preferences: Audio quality perception varies. Ensure your audio system, playback device, and environment are optimal.
