Features
Ampapa × Douk Audio Collaboration: Built on the acclaimed Douk Audio A5 amp, the D1 retains core features like TPA3255 chip, HPF, PRE-OUT, socketed op-amps—now upgraded with digital VU display, TRS balanced input, Bluetooth 5.2, treble/bass control, remote and more for next-gen HiFi performance.
Digital VU Meters with Retro Soul: D1 features a vibrant OLED screen that merges classic aesthetics with modern utility. Enjoy 7 VU styles in classic yellow, blue, or black and view real-time feedback of all operations and playback. Both stylish and functional, it brings your music to life.
Engineered for True 2.1 Systems: The adjustable 30–200Hz high-pass filter removes low frequencies from the main output, letting your stereo speakers focus on mids and highs with better clarity, while PRE-OUT offers full-range signal to active subwoofers, amplifiers, or active speakers.
Premium Components for Superior Fidelity: Pluggable NE5532 op-amps allow for effortless upgrades through the top glass panel for long-term flexibility. From NJW1194 chip, SAGAMI inductors, 2oz copper PCB to GaN 48V/5A power adapter, every element is chosen for sonic purity.
Engineered for Everyday Convenience: With a 12V trigger, infrared remote, one-touch mute and Bluetooth reset, D1 simplifies your daily audio setup. Fine-tune your sound with ±10dB tone control, while internal RGB lighting adds a refined, modern glow. Enjoy seamless operation from start to finish.
Q: Can I replace the op-amps in the D1？
A:Yes, the D1 uses 2PCs pluggable NE5532 op-amps,which can be replaced by normal dual op-amps like 2604/2134/muses02 etc. Before replacing, please turn off the power, ensure correct orientation, and power ononly after confirming proper installation.

Q: Why don't the single VU meter and spectrum display work properly?
A: In dual VU meter mode, both meters show the audio levels for the left and right channels separately.In single VU meter and spectrum modes, the D1 only detects the left channel input. If only the right channel is connected, the VU meter and spectrum display will not operate.

Q: Does the high-pass filter affect the Pre-Out signal?
A:No,the high-passfilteronly applies to the speaker output. The Pre-Out delivers a full-range signal.

Q: Are the Pre-Out's volume and tone controls synchronized with the speaker output?
A: Yes.
A: Yes.
Q: Is it normal for the D1 to become hot during operation?
A: The D1's TPA3255 amp chip dissipates heat through contact with the chassis. It is normal for the chassis to heat up during operation. This does not affect performance or lifespan of the D1. Please place the D1 in a well-ventilated area,and avoid stacking devices or blocking ventilation.

Q: What should I use the 12V trigger input for?
A: The 12V trigger input is designed for use with preamps or DACs that have a trigger output to achieve synchronous power on and off. Please do not use this port as an audio input or connect it to a power supply, as this could damage the D1.
