GLABS Z4.20 AMPLIFIER

Description

• The GLABS Z4.20 delivers exceptional power and performance in a compact 1U rackmount design, outputting 4 x 2100W RMS @ 8Ω, 4 x 3360W @ 4Ω, and 4 x 5040W @ 2Ω, making it ideal for large-format PA systems, touring rigs, or fixed installations.
  
• For higher output needs, bridge mode powers up to 2 x 8820W @ 4Ω, 2 x 6930W @ 8Ω, and 2 x 4200W @ 16Ω, enabling robust subwoofer or high-demand full-range configurations.
  
• Class D architecture ensures high energy efficiency, reduced heat and minimal weight without compromising sound quality.
  
• Offers pristine audio with <0.5% THD+N, wide 10Hz–20kHz ±0.35dB frequency response and >102dB S/N ratio, ensuring clean, detailed audio even under load.
  
• Excellent damping factor >5000 (8Ω) and a slew rate >30V/μs maintain tight bass control and dynamic signal response.
  
• Voltage gain: 45.5dB (0.775V to 130V), with selectable input sensitivity (0.775V, 1V, 1.4V) for flexible integration with various mixers and DSPs.
  
• Inputs: Balanced XLR (pin 1 ground, pin 2 +, pin 3 -), with 10KΩ balanced / 20KΩ unbalanced impedance.
  
• Outputs: 2 Neutrik NL4 sockets + 2 binding post outputs, supporting diverse speaker configurations.
  
• Full suite of protection: short circuit, DC, overload, thermal, RF, ultrasonic, and peak voltage limiting—engineered for consistent reliability in any scenario.
  
• Dual-voltage support (110V/220V) and dual F-20A fuses provide operational flexibility across regions.
  
• Idle power consumption <155W, maximum <8500W — optimized for energy-conscious, high-demand environments.
  
• Chassis dimensions: 500mm x 483mm x 45mm (1U), packaged dimensions: 655mm x 630mm x 130mm.
  
• Lightweight and portable at 13kg net / 15.5kg gross, ensuring easy transport and rack integration.
