The AUWAY GMX4400 is a versatile 4-channel professional power amplifier that combines compact design with professional-grade performance, built around a Class H circuit for balanced efficiency and sound quality. Housed in a space-saving 2U chassis (490x520x90mm), it delivers 4x400W @8Ω (stereo) and 4x600W @4Ω (low-impedance), with bridged outputs of 1200W+1200W @8Ω and 1600W+1600W @4Ω. A unique feature of the GMX4400 is its optional transformers: choose a copper transformer for premium performance (lower distortion, higher efficiency) or an aluminum transformer for budget-friendly reliability. This amplifier is tailored for multi-zone audio systems—from restaurant background music to church satellite zones—where space, flexibility, and consistent sound are priorities.
• 4 independent channels: Powers up to 4 speakers or speaker zones, eliminating the need for multiple 2-channel amplifiers—saves rack space and reduces wiring complexity.
• Versatile bridged modes: 1200W+1200W @8Ω or 1600W+1600W @4Ω bridged mono lets you combine channels for higher power (e.g., driving subwoofers or large main speakers in two zones).
• Independently adjustable volume: Each channel has a dedicated volume knob, making it easy to balance sound across zones (e.g., quieter background music in a restaurant dining area, louder audio in a bar).
• Copper transformer (premium): Delivers lower distortion, higher efficiency, and better heat dissipation—ideal for critical applications (e.g., conference center main halls, high-end retail).
• Aluminum transformer (value): Offers reliable performance at a lower cost, perfect for non-critical uses (e.g., background music in hotels, museum exhibit sound).
• Both transformers feature dense winding and PVC anti-magnetic shielding: Minimizes interference from other gear (e.g., mixers, LED controllers) and ensures clean audio.
• <0.05% THD (20Hz-20kHz at rated power): Ultra-low distortion ensures clear speech and music, even at low volumes (e.g., museum audio guides, restaurant background music).
• 20Hz-20KHz (+0/-0.5dB) frequency response: Full-range coverage captures every detail, from deep bass (e.g., jazz upright bass) to crisp highs (e.g., speech, acoustic guitar).
• >80dB channel separation: Prevents crosstalk between channels, ensuring independent control over each zone (e.g., adjusting bar audio won’t affect dining area sound).
• >400 damping factor: Tightens bass response, ideal for both small background speakers and larger zone speakers (e.g., retail store ceiling speakers, church satellite speakers).
• Background music systems: Powers speakers in restaurants, retail stores, or hotels, with independent volume control for different zones (e.g., dining area, lobby, restrooms).
• Restaurant and retail audio zones: Balances sound levels—quieter music in dining areas, louder audio in bars or retail floors—to enhance customer experience.
• Hotel multi-area distribution: Drives speakers in lobbies, hallways, and conference rooms, ensuring consistent audio quality across the property.
• House of worship satellite zones: Powers speakers in chapels, fellowship halls, or outdoor prayer areas, syncing with the main sanctuary sound (via a mixer).
• Conference center room audio: Drives speakers in multiple meeting rooms, with volume adjustment for each room (e.g., small huddles, large presentations).
• Museum and exhibit sound: Delivers clear audio for exhibit descriptions or videos, with low distortion ensuring visitors can hear details even at low volumes.
• Stage monitor systems: Powers up to 4 stage wedges, with independent volume for each musician (e.g., vocalist, guitarist, drummer) to customize their monitor mix.
• Delay tower amplification: Drives speakers in delay towers for large venues (e.g., stadiums, festivals), extending sound coverage to rear audience sections.
• Front-fill speaker arrays: Powers front-fill speakers, filling sound gaps near the stage and ensuring audience members up front hear clearly.
The GMX4400 can power up to 4 speakers (one per channel) in stereo mode (e.g., 4x8Ω speakers at 400W each). If using bridged mode, it can power 2 speakers (one per bridged pair) at higher power (e.g., 2x8Ω speakers at 1200W each). Always ensure the total impedance per channel/bridged pair does not drop below 4Ω.
• Copper transformers: Have lower electrical resistance, so they deliver more power with less heat and distortion. They’re better for critical applications where sound quality is top priority (e.g., conference presentations, high-end retail).
• Aluminum transformers: Have slightly higher resistance but are more affordable. They’re ideal for non-critical uses (e.g., background music) where cost matters more than ultra-premium sound.
Both options include anti-magnetic shielding to prevent interference.
Yes. It’s a 2U rack-mount amplifier, fitting standard 19-inch equipment racks. Its compact size (490x520x90mm) saves space, making it ideal for rack setups with limited room (e.g., hotel AV closets, small venue backrooms). The front panel features clear LED indicators (power, signal, protect) for easy monitoring during installation.
Yes. Its Class H design is efficient, reducing heat generation, and the temperature-controlled cooling system ensures it stays within safe operating limits. The robust power supply and high-quality components (e.g., sealed capacitors, imported transistors) also support continuous operation—perfect for 24/7 installations like museum exhibits or hotel lobbies.
