The AUWAY GB1000 is a professional power amplifier that redefines mid-range performance with its innovative Class GB Technology—a hybrid design that merges the efficiency of Class D with the sonic purity of Class AB. As a 3U rack-mount unit, it delivers 2x1000W @8Ω (stereo), 2x1400W @4Ω (low-impedance), and flexible bridged outputs: 2800W @8Ω and 3900W @4Ω. What sets the GB1000 apart is its robust internal components: 4 high-capacity filter capacitors (for stable power delivery) and 14 power transistor pairs per channel (for consistent current output). This amplifier is built for professionals who need reliable, high-quality sound in medium venues—from stage monitors to nightclub speaker arrays—without sacrificing efficiency or durability.
• Balanced efficiency and sound quality: Outperforms Class AB in energy savings (lower heat, less power use) and matches Class D’s efficiency while maintaining the warm, natural sound of Class AB—perfect for critical applications like live music or worship.
• 2800W @8Ω / 3900W @4Ω bridged mono: Offers versatility for single-speaker setups (e.g., large subwoofers or main PA enclosures), eliminating the need for multiple amplifiers in space-constrained racks.
• Reduced heat buildup: Class GB design cuts heat generation by 25% compared to Class AB, allowing extended operation (e.g., 8-hour festival sets) without overheating.
• <0.05% THD (@8Ω 1kHz at 1/10 power): Ultra-low distortion ensures vocals, instruments, and music retain their original character—no harshness or coloration.
• 20Hz-20kHz (±1dB) frequency response: Captures every detail, from deep basslines (20Hz) to high-frequency harmonics (20kHz), making it suitable for diverse genres (rock, jazz, electronic).
• >75dB channel separation (@8Ω 1kHz): Prevents signal bleed between channels, ensuring clean stereo imaging for PA systems or independent control over stage monitors.
• >400 damping factor: Tightens bass response by controlling speaker cone movement, ideal for subwoofers and full-range speakers that need precise transient handling.
• 14 power transistor pairs per channel: Delivers consistent current to speakers, even under high-load conditions (e.g., driving multiple speakers per channel).
• 4 high-capacity filter capacitors: Stabilize power delivery, reducing voltage drops during dynamic peaks (e.g., drum hits or guitar solos) and minimizing interference.
• Professional connectivity: Balanced XLR inputs (for noise-free signal transmission from mixers) and Speakon outputs (secure, industry-standard speaker connections) ensure reliable integration with existing gear.
• Medium venue main PA systems: Powers speakers for venues with 150–300 attendees (e.g., small theaters, clubs), delivering enough headroom to handle dynamic music without clipping.
• Stage monitor amplification: Provides clear, loud signals to stage wedges, allowing musicians to hear themselves over the crowd—critical for tight performances.
• Outdoor event sound: Performs reliably in variable conditions (e.g., outdoor concerts or festivals) thanks to efficient cooling and robust power supply.
• House of worship sound systems: Reproduces speech and music with clarity, supporting services from small congregations to large worship bands.
• Conference center audio: Drives speakers in meeting rooms or auditoriums, ensuring speech is crisp and audible across all seating areas.
• Performance venues: Adapts to theater productions or live shows, capturing the nuance of vocals and instruments for audience enjoyment.
• Nightclub speaker arrays: Handles high-volume dance music, maintaining clarity even during extended DJ sets (4–6 hours).
• Live music venue installations: Powers speakers in bars or small clubs, supporting bands with diverse sound needs (acoustic, rock, or electronic).
• High-end KTV systems: Enhances vocal performance with low distortion, ensuring singers hear their voice clearly alongside backing tracks.
The 14 power transistor pairs per channel ensure the GB1000 can deliver consistent current to speakers, even under high-load conditions. Transistors handle the amplification of audio signals, and more pairs mean the amplifier can distribute heat evenly (reducing wear) and supply more power to low-impedance loads (e.g., 4Ω speakers). This is critical for applications like driving multiple speakers per channel or handling dynamic music peaks.
Yes. Its 2x1000W @8Ω stereo output lets you assign one channel to main PA speakers and the other to stage monitors. The >75dB channel separation prevents crosstalk, so adjustments to monitor volume won’t affect the main mix. Additionally, the low THD ensures both speech (monitors) and music (main PA) remain clear.
The GB1000 operates on 220V~240V AC, compatible with standard power in most regions. Its robust power supply with noise filtering also minimizes interference from unstable power sources (common in venues), ensuring consistent performance.
The GB1000 has a net weight of 32 KG and gross weight of 36 KG. While it’s heavier than compact amplifiers, its 3U rack-mount design fits standard equipment racks, making it easy to transport with touring rigs. For solo use, we recommend a rack dolly to simplify moving it between venues.
