Product Overview
High-Performance Subwoofer Amplifier for Professional Stage Audio
The DA-1000 Dual Channel 1000W Power Amplifier is a cornerstone of professional sound reinforcement. As a dedicated subwoofer amplifier, it provides the high-current output needed to drive heavy-duty low-frequency drivers without distortion. Whether you are building a massive concert rig or a permanent club installation, this unit amplifier delivers consistent, clean power that ensures your audio stays crisp even at peak volumes.
At JJY Stage, we understand that global B2B buyers need equipment that is both powerful and reliable. The DA-1000 is engineered to handle the rigorous demands of the touring industry. While it functions beautifully as a standalone amplifier speaker driver, its architecture allows it to integrate perfectly into complex systems, providing the necessary drive for high-fidelity line array speakers in large-scale outdoor events.

Frequently Asked Questions (FAQs) – DA-1000 Power Amplifier
To help our global B2B partners and event production teams, we have compiled the most common questions regarding the DA-1000 and our manufacturing services in China.
1. Can the DA-1000 drive high-power line array speakers?
Yes. The DA-1000 is specifically designed with high-current headroom to handle the dynamic loads of professional line array speakers. Its dual-channel efficiency ensures that each frequency band receives clean, undistorted power, which is critical for maintaining clarity in large-scale outdoor setups.
2. Is this unit stable enough to be used as a dedicated subwoofer amplifier?
Absolutely. While many standard amplifiers struggle with low-frequency heat, the DA-1000’s internal circuitry is optimized to act as a powerful subwoofer amplifier. It provides the consistent “low-end punch” required for heavy 18-inch subwoofers without thermal throttling.
3. What does a power amplifier look like when installed in a 2U rack?
The DA-1000 follows the standard industrial 2U rack-mount format. It features a heavy-duty front panel with reinforced mounting “ears,” dual cooling intake vents, and clear LED indicators for signal, clip, and protection modes. It is designed to look professional and stay secure in both touring racks and permanent installations.
4. Do you offer OEM customization for wholesale orders?
As a leading China manufacturer, JJY Stage offers full OEM/ODM services. We can customize the front panel with your company logo, adjust the gain settings, or even modify the chassis color. For distributors, we also provide custom-branded packaging and localized manuals to help you build your own brand identity.
5. How does the DA-1000 compare to a 5 channel amplifier?
A 5 channel amplifier is typically used for multi-zone background music or home theaters. However, for professional stage audio, the DA-1000’s dual-channel design is superior because it focuses all available power into just two channels. This provides much higher “watts-per-channel” performance, which is necessary for driving large stage speakers.
6. Can I use this as a bass amplifier for live instruments?
Yes. While it is a rack-mount power unit, many touring professionals use the DA-1000 as the primary bass amplifier engine for high-output instrument cabinets. It provides a much cleaner and more powerful signal than a standard portable guitar amplifier, giving bassists massive headroom on stage.
7. What are the export and shipping options for international buyers?
We regularly export to wholesalers and rental companies worldwide. We offer flexible Incoterms (FOB, CIF, EXW) and provide all necessary certifications (CE, RoHS) for customs clearance. For bulk orders, we use reinforced export-grade cartons or optional flight cases to ensure the equipment arrives in perfect condition.
