• Built for Real Tactile Bass: Purpose-built bass shaker amplifier for tactile transducers. Designed to drive Douk Audio BS-1/BS-2 and similar bass shakers, the G100 provides dedicated low-frequency power for adding more physical feedback to gaming chairs, home theater seats, sofas, and sim racing rigs.
• Flexible BTL/PBTL Output Modes: Use BTL mode to power two bass shakers with 50W×2 output for wider tactile coverage, or switch to PBTL mode for 100W×1 mono output to drive one shaker with stronger, more focused impact. Also supports passive subwoofers for more flexible setups.
• Adjustable Low-Pass Filter: The 50–300Hz adjustable low-pass filter lets you control the bass range sent to your shaker, helping focus on deep effects like engines, explosions, impacts, and cinematic bass while reducing unwanted higher-frequency vibration for cleaner, tighter feedback.
• RCA and Bluetooth 5.3 Input: Connect easily by RCA input from a TV, computer, audio player etc. or use Bluetooth 5.3 to receive wireless signals from phones, tablets, and computers. Bluetooth reset is also supported for easy reconnection.
• Stable Build for Long Sessions: Optimized circuit design, upgraded heat dissipation, and quality components help maintain stable low-frequency output during long sessions. Its compact aluminum chassis fits beside your audio system, under a seat, or in tight spaces.

User Manual of Douk Audio G100

FAQs

Q: Why isn't D1 syncing power on and off with my other devices via the 12V Trigger?
A: The D1's 12V Trigger uses a TRS connection. Please use a TRS cable (compatible with both TS and TRS jacks) to link to the trigger output of your other devices.

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-pass filter only 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.

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.

Q: What is the required power supply for the D1?
A: The D1 requires a DC 24-48V (≥4A) input voltage. Please use the supplied power adapter for optimal performance. lf using a third-party power supply,ensure it meets the required voltage and current specifications.

Q: Why doesn't the remote control include batteries?
A: For safer and faster delivery, the remote control may not include batteries (AAA*2). Please prepare them yourself.
