GLABS HT4.7 AMPLIFIER

Description

• The GLABS HT4.7 is a robust and efficient 4-channel Class D amplifier engineered for high-demand professional audio applications, including touring systems, installations and large-scale sound reinforcement.
• Offers impressive multi-channel output: 4 x 800W @ 8Ω, 4 x 1280W @ 4Ω, and 4 x 1920W @ 2Ω, providing exceptional versatility and power in both stereo and bridge configurations.
• Bridge mode delivers 2 x 1600W @ 16Ω, 2 x 2640W @ 8Ω, and 2 x 3360W @ 4Ω, making it suitable for high-power mono applications or subwoofer driving.
• Wide frequency response of 10Hz–20kHz (±0.35dB) ensures precise and transparent sound reproduction across the full audible range.
• Low total harmonic distortion (<0.5%) and an excellent signal-to-noise ratio (>100dB) offer crystal-clear output, even at high volumes.
• A slew rate exceeding 30 V/μs and damping factor >3000 (8Ω) provide tight control over speaker movement and enhanced audio clarity, especially in the low-end spectrum.
• Selectable input sensitivity options (0.775V, 1V, 1.4V, 2V) ensure flexible system integration, while high input impedance (10kΩ balanced / 20kΩ unbalanced) allows compatibility with a variety of sources.
• Equipped with 4 XLR balanced inputs and 4 Neutrik NL4 speaker output sockets, offering secure and reliable professional connections.
• Comprehensive protection features safeguard against short-circuit, DC faults, overload, overheating, ultrasonic interference, RF interference and voltage peaks.
• Dual-voltage design (110V/220V) with F-20A fuse allows global usability and consistent performance in varied electrical environments.
• Highly energy-efficient with <110W idle and <2000W maximum power consumption, supporting long-term operation with reduced thermal stress.
• Compact 1U rack-mount form factor (483×420×45mm) with a net weight of 8kg, making it ideal for installations where space and weight are critical.
• A trusted amplifier solution for professionals seeking powerful, reliable multi-channel amplification in a space-efficient and durable package.
