The Digital Class D Power Amplifier 4X450W 8Ω Per Channel is a high-performance audio solution designed for professional and residential environments where space-saving design and robust power output are critical. Combining cutting-edge Class D technology with a compact footprint, this amplifier delivers exceptional clarity and efficiency, making it ideal for multi-zone audio systems, background music setups, and high-energy entertainment venues.
Engineered to handle 450 watts per channel into 8Ω across four independent channels, this amplifier ensures distortion-free audio even at peak loads. Its advanced thermal management system prevents overheating, while the lightweight, mini-bar design allows seamless integration into tight spaces like DJ booths, retail displays, or home theater cabinets. Compatible with a wide range of input sources—including mixers, streaming devices, and microphones—the amplifier supports balanced XLR, TRS, and RCA connections, offering versatility for diverse setups.
Whether powering ceiling speakers in a restaurant, subwoofers in a nightclub, or outdoor audio systems, this amplifier excels in delivering crisp highs, detailed mids, and punchy lows. Its user-friendly interface includes intuitive LED status indicators and protection circuits against overloads, short circuits, and DC offsets, ensuring long-term reliability for demanding applications.
1. High-Efficiency Class D Technology: Achieves up to 90% efficiency, reducing energy consumption and heat generation compared to traditional Class AB amplifiers.
2. 4x450W @ 8Ω Output: Drives multiple speakers simultaneously with clean, dynamic power, perfect for large venues or distributed audio systems.
3. Ultra-Compact Design: Mini-bar form factor (2U rack-mountable) saves space without compromising performance.
4. Multi-Protection Mechanisms: Integrated safeguards against overloads, short circuits, overheating, and inrush current surges.
5. Versatile Connectivity: Features XLR, TRS, and RCA inputs with loop-through outputs for daisy-chaining multiple amplifiers.
6. Low-Noise Operation: Advanced shielding and signal processing minimize hum and interference for pristine audio quality.
7. LED Status Monitoring: Real-time indicators for power, signal, clipping, and fault alerts simplify troubleshooting.
8. Bridgeable Channels: Combine two channels for higher power output (up to 900W @ 8Ω) to accommodate subwoofers or high-demand speakers.
9. Universal Power Supply: Auto-voltage detection (100V–240V AC) ensures global compatibility.
10. Robust Build Quality: Durable steel chassis with anti-vibration feet for stable performance in mobile or fixed installations.
This amplifier is engineered for versatility across commercial and residential settings:
· Hospitality Venues: Power background music in hotels, bars, and restaurants with zone-specific volume control.
· Live Sound: Ideal for small to medium stages, DJ setups, or portable PA systems requiring high headroom.
· Retail & Worship Spaces: Deliver clear announcements and ambient music across large showrooms or auditoriums.
· Home Entertainment: Integrate into custom home theaters or multi-room audio systems for immersive listening.
· Outdoor Events: Weather-resistant speaker compatibility makes it suitable for patios, stadiums, or festivals.
· Installation Projects: Use with 70V/100V line transformers for distributed speaker systems in schools or offices.
Its ability to drive low-impedance and high-impedance loads ensures compatibility with virtually any passive speaker configuration.
The Digital Class D Power Amplifier comes with a 3-year limited warranty, covering defects in materials and workmanship under normal use. Customers must register the product online within 30 days of purchase to activate coverage. The warranty includes free repair or replacement of faulty components, excluding damage caused by misuse, unauthorized modifications, or environmental factors (e.g., water exposure, voltage spikes).
Technical support is available via email, phone, or live chat during business hours. For expedited service, customers can leverage our global network of authorized service centers. Extended warranty plans (up to 5 years) are optional and include priority repair services. Always retain proof of purchase for warranty claims.
Q1: Is the 450W output per channel RMS or peak?
A: All power ratings are RMS (continuous), ensuring reliable performance under sustained use.
Q2: Can I bridge all four channels for a single subwoofer?
A: No, bridging is limited to two channels at a time (e.g., Channels 1+2 or 3+4).
Q3: Does the amplifier include a cooling fan?
A: Yes, a variable-speed fan activates under heavy loads, ensuring quiet operation during low-demand scenarios.
Q4: What input types are supported?
A: The amplifier accepts balanced XLR, TRS, and unbalanced RCA inputs.
Q5: How do I protect speakers from overloads?
A: Built-in limiters adjust gain dynamically to prevent clipping and speaker damage.
Q6: Is the warranty international?
A: Yes, but service options vary by region. Check local authorized dealer policies.
Q7: Can I mount this amplifier vertically?
A: Yes, the chassis supports vertical stacking or rack mounting using standard brackets.
Q8: Does it work with 4Ω speakers?
A: Yes, but power output increases to 650W per channel—ensure adequate ventilation.
Q9: Is this suitable for home stereo systems?
A: Absolutely. Its compact size and clean power make it ideal for high-end home audio.
Q10: What’s included in the box?
A: The amplifier, power cable, user manual, and rack-mount ears (if applicable).
This product combines professional-grade performance with user-centric design, redefining expectations for compact power amplifiers.
