Ampapa × Douk Audio Collaboration: Built on the critically acclaimed Douk Audio A5 amplifier, the D1 inherits core features such as the TPA3255 chip, HPF, PRE-OUT, and socketed op-amps—and further upgrades with a digital VU display, TRS balanced inputs, Bluetooth 5.2, treble/bass control, and remote control to deliver next-generation HiFi performance. A digital VU meter imbued with a retro spirit: The D1 features a vibrant OLED screen that blends classic aesthetics with modern practicality. Enjoy seven VU styles in classic yellow, blue, or black, and see real-time feedback for all operations and playback. Stylish and functional, it brings music to life. Designed for a true 2.1 system: The adjustable 30–200Hz high-pass filter removes low frequencies from the main output, allowing stereo speakers to focus on mid-range and high frequencies with superior clarity. At the same time, the PRE-OUT provides a full-range signal to an active subwoofer, amplifier, or active speakers. Premium components for superior fidelity: The replaceable NE5532 op-amp allows for easy upgrades through the top glass panel, providing long-term flexibility. From the NJW1194 chip and Sagami inductors to the 2oz copper PCB and GaN 48V/5A power adapter, every element has been carefully selected for sonic purity. Designed for everyday convenience: With a 12V trigger, infrared remote control, one-touch mute, and Bluetooth reset, the D1 simplifies your daily audio setup. Fine-tune your sound with ±10dB tone control, and internal RGB lighting adds a sophisticated, modern glow. Enjoy seamless operation from start to finish. Note: The D1's 12V trigger uses a TRS connection. To connect to the trigger output of other devices, please use a TRS cable (compatible with both TS and TRS jacks). This product cannot be connected to a passive subwoofer, but the PRE OUT can be connected to an active subwoofer to create a 2.1ch system. Ampapa D1 & A1 The perfect pairing for pure audio bliss. Amplifying all your passion -- after three years of dedicated craftsmanship, Ampapa proudly presents its second masterpiece, the D1 digital amplifier.
