The Fosi Audio TB10D is a high-performance Class D power amplifier designed to deliver massive energy in a compact footprint. As an upgraded version of its predecessors, it focuses on raw driving power and sonic clarity, making it an ideal choice for audiophiles who want to push their passive speakers to their full potential.
Incredible 600W Output: Equipped with the premium Texas Instruments TPA3255 amplifier chip, the TB10D delivers up to 300W x2 (@4Ω). It provides deep, controlled bass and crystal-clear highs, even at high volume levels.
Ultra-Low Distortion: Maintains high efficiency while keeping Total Harmonic Distortion (THD ≤ 0.03%), ensuring that your music stays true to the original recording.
Tactile Tone Tuning: Features independent Bass and Treble knobs with a center-detent (middle position) for a flat response. This allows you to easily compensate for room acoustics or tailor the sound to your personal taste.
Efficient Heat Dissipation: The solid aluminum alloy chassis acts as a natural heatsink, ensuring stable performance during long listening sessions.
Plug-and-Play RCA Input: Standard RCA inputs make it compatible with DACs, CD players, streamers, or your computer's audio output.
High-Quality Terminals: Gold-plated speaker binding posts ensure a secure connection for banana plugs or raw speaker wire.

The Fosi Audio TB10D is the perfect solution for those who prioritize performance and value. It strips away unnecessary features like Bluetooth to focus entirely on amplification quality. If you already have a high-quality DAC or streamer and need a "workhorse" amp to drive your speakers, the TB10D is the most powerful option in its price bracket.
Choose the Fosi Audio TB10D if you want a simple, powerful "workhorse" amp. The physical tone controls are perfect if your speakers or room acoustics need a bit of adjustment (e.g., boosting the bass). It offers the best value for raw power.
Choose the Fosi Audio V3 if you are an audiophile who wants the cleanest signal possible. It removes tone controls to prevent signal interference and features swappable Op-Amps, allowing you to customize the sound signature later. The Pre-out port also makes it easier to add an active subwoofer.

I. Function & Performance Clarifications
1. Power Output & Supply: The TB10D's max power output depends on the power supply. With the included 32V 5A supply, it delivers 100W at 4Ω and 130W at 8Ω. For higher power, a 48V 10A supply is needed to reach 280W at 4Ω and 300W at 8Ω per channel, and 600W (300W per channel) chip power.
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 5.59x4.13x1.38in.
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.
2. Bass Shaker & Single Channel Issues: Ensure correct wiring. If your bass shaker isn't working, check its compatibility as we can't confirm without its model info.
3. Compatibility Limitations: This two - channel amp is for passive speakers only. It won't work with subwoofers.
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.
