Compact Class D Stereo Power Amplifier

The Mini 300 is a compact Class D stereo power amplifier designed for desktop hi-fi audio systems. Its fully balanced amplification structure supports stereo sound output with low distortion, while balanced TRS and unbalanced RCA inputs provide flexibility when connecting compatible audio equipment. The aluminium alloy body and compact desktop format make it an option for audio setups where space and connection options matter.

Key Features

• Class D Amplification: Uses a Class D amplifier circuit to deliver high-power stereo audio output with low distortion.

• Stereo Sound Output: Provides 2-channel amplification with an output power of 140W × 2 at 10% distortion into a 4Ω load.

• Balanced Amplification Structure: Helps improve resistance to interference during audio amplification.

• Dual Input Options: Supports balanced TRS and unbalanced RCA inputs, allowing connections to compatible audio sources without additional converters.

• Aluminium Alloy Body: Features an all-aluminium alloy housing with heat dissipation windows on the bottom and sides.

• 12V Trigger Function: Supports linked power on/off operation with other compatible devices when the switch is set to the TRIG position.
