The AUWAY A400 is a trusted 2-channel professional power amplifier built on the proven CA-series circuit design—a topology known for decades of reliable performance—now enhanced with an upgraded front panel for modern aesthetics and easier monitoring. As a compact 2U rack-mount unit (485x426x90MM), it delivers consistent power: 2x400W @8Ω (stereo), 2x600W @4Ω (low-impedance), and 1200W @8Ω in bridged mono. Designed for small-to-medium applications, the A400 features a 40V/ms slew rate (for fast transient response) and >80dB channel separation (for clean stereo imaging), making it ideal for venues like small churches, KTV rooms, and wedding halls. Its balance of reliability, performance, and affordability has made it a favorite for users who prioritize long-term dependability over excessive power.
• Decades of field-tested performance: The CA-series circuit is used in thousands of installations worldwide, known for minimal component failure and consistent sound—ideal for users who want a “set-it-and-forget-it” amplifier (e.g., small churches, wedding venues).
• Stable power delivery: Maintains 2x400W @8Ω even under variable load conditions (e.g., connecting one 8Ω and one 4Ω speaker), ensuring sound doesn’t drop or distort during use.
• Low maintenance: Uses high-quality components (e.g., sealed capacitors, durable transistors) that require little to no upkeep, reducing long-term costs for small businesses or organizations.
• Modern, intuitive design: Features clear LED indicators (POWER, SIGNAL, CLIP, PROTECT) that let you quickly monitor status—e.g., a “CLIP” light means volume is too high, while “PROTECT” signals a wiring issue.
• Easy-to-access controls: Volume knobs are large and labeled for each channel, making it simple to adjust levels (e.g., balancing left/right speakers in a KTV room or lowering volume for a wedding’s cocktail hour).
• Sleek aesthetics: The upgraded panel fits modern AV racks, replacing the older CA-series’ utilitarian design with a professional look that complements other gear (e.g., mixers, media players).
• <0.05% THD (20Hz-20KHz): Ultra-low distortion ensures speech and music are clear—critical for wedding speeches, church sermons, or KTV vocals.
• 20Hz-20KHz (+0/-0.5dB) frequency response: Full-range coverage captures deep bass (e.g., wedding reception music) and crisp highs (e.g., a pastor’s voice or a singer’s high notes).
• >400 damping factor: Tightens bass response, ideal for small speakers (e.g., KTV room speakers or church PA cabinets) and ensuring music feels punchy without muddiness.
• Small to medium venues (50–200 attendees): Powers main PA speakers for events like birthday parties, small concerts, or community gatherings, with 2x400W @8Ω delivering enough volume to fill the space.
• Wedding halls: Adapts to different moments—stereo mode for background music during cocktails, bridge mode (1200W @8Ω) for a subwoofer during the dance party, and low distortion for speeches.
• Outdoor activities (small): Drives speakers for backyard weddings or community festivals, with robust power supply handling generator power (common outdoors) and efficient cooling handling ambient heat.
• Houses of worship (small): Powers PA speakers for sermons and worship music, with reliable CA-series circuit ensuring daily use (7 days a week) without failure and low distortion preserving vocal clarity.
• KTV rooms: Enhances vocal performance with clean sound, allowing singers to hear themselves clearly alongside backing tracks—stereo mode powers main speakers, and the upgraded panel makes it easy for staff to adjust volume.
• Small retail stores: Delivers background music, with parallel mode (if using multiple speakers) ensuring consistent sound across the store and quiet fan operation avoiding customer distraction.
• Club stage monitors: Powers small stage wedges for solo artists or small bands, with >80dB channel separation ensuring monitor mixes don’t interfere with the main PA and low THD preserving instrument detail.
• Studio monitors (small): Delivers accurate sound for home recording studios, with wide frequency response ensuring mixes translate well to other systems (e.g., headphones, car stereos).
The CA-series circuit has been used in AUWAY amplifiers for years, with a track record of:
• Reliability: Minimal component failure, even with daily use (e.g., small churches that run services 3x weekly).
• Stability: Consistent power output across different loads (e.g., 8Ω or 4Ω speakers) and power conditions (e.g., generator power outdoors).
• Ease of repair: Simple circuit design means if issues arise, repairs are straightforward and affordable—critical for small businesses or organizations with limited AV budgets.
Yes, in bridge mode. The A400 delivers 1200W @8Ω in bridged mono, which is enough to power a small-to-medium subwoofer (e.g., a 12” or 15” subwoofer in a KTV room or wedding hall). Bridge mode combines both channels into a single high-power output, making it ideal for subwoofers that need more power than a single stereo channel can provide.
The A400 is a 2U rack-mount amplifier, meaning it occupies 2 units of space in a standard 19-inch rack (each unit = 1.75 inches/44.45mm). Its dimensions are 485x426x90MM (WxLxH), making it compact enough for small racks (e.g., a 4U rack in a KTV room or church AV closet).
The A400 includes essential protection to prevent damage:
• DC fault protection: Shuts down output if a DC signal is detected (e.g., faulty speaker wiring), protecting speakers from burnout.
• Overload protection: Reduces power if the amplifier is pushed beyond its limits (e.g., too much volume), preventing overheating.
• Output relay switch: Isolates speakers during power-on/off to avoid “pop” noises and surge damage.
• Overheat protection: Mutes output if heatsink temperature exceeds safe levels, auto-recovering once cooled.
