AMPAPA D1 - 2-Channel Bluetooth HiFi Amplifier 300W x2, BT 5.2

Meet the AMPAPA D1: A Modern HiFi Amplifier with Vintage Soul

Engineered as a versatile 2.1-ready amplifier, the D1 blends Douk Audio heritage with contemporary digital touchpoints. Its heart is a TPA3255-based circuit that powers bookshelf speakers with clarity and authority, while the PRE-OUT expands your setup to active subwoofers or larger systems. In daily use, you’ll notice a balanced, engaging presentation across genres, from delicate acoustic passages to dynamic electronic tracks.

Real-time feedback meets retro aesthetics thanks to the OLED digital VU meters. Choose from seven display styles in yellow, blue, or black, and watch levels update as you listen. This visual feedback is designed to feel purposeful, helping you gauge volume, source, and playback status at a glance—without distracting from your music.

Key features for flexible setups

• 2-channel class-AB amplification delivering up to 300W x 2 into capable bookshelf speakers
• Digital VU meters for at-a-glance signal status
• 30–200 Hz high-pass filter to optimize speaker performance by trimming low-end bleed
• PRE-OUT for subwoofers and expansion into larger rooms with full-range signal
• Bluetooth 5.2 for wireless streaming with steady pairing
• Tone control with ±10 dB adjustment for treble and bass, enabling personal tuning
• IR remote, one-touch mute, and Bluetooth reset for quick, intuitive control
• Internal RGB lighting adds a refined ambience that won’t overpower your setup

All this is built with premium components chosen for sonic purity. You can explore upgrades with socketed op-amps and a clean signal path that reduces load dependence through PFFB technology. A high-grade NJW1194 chip, SAGAMI inductors, and a 2oz copper PCB contribute to stability and low distortion, while the GaN-based 48V/5A power adapter delivers reliable, clean power under dynamic playback.

Everyday use is made simple by smart conveniences: a 12V trigger to integrate with other gear, infrared remote for convenient control from your couch, and a subtle RGB glow that adds ambience without distraction. The combination of a compact chassis and robust internals makes it well-suited for desks, living rooms, or home theater shelves where you want noticeable performance without bulky equipment.
