Audio amplifier KNIPMG-600 D4

IPdistributionClass D

Product Overview
The KNTECH KNIPMG-600 Series IP Amplifier is a 600W Class-D networked public address/voice alarm (PA/VA) amplifier platform engineered for 24/7 mission-critical installations. It provides intelligent power delivery, high-fidelity audio, flexible output assignment and certified life-safety compliance for environments such as transit hubs, hospitals and large public facilities.

Key Functional Features & Benefits

• Intelligent Power Delivery with Class-D efficiency: 600W Class-D amplification for reduced power consumption and heat dissipation, improving operational lifespan for continuous operation.
• High-fidelity audio: Distortion < 0.5% at rated power and wide frequency response for clear, intelligible announcements that cut through ambient noise.
• Versatile output architecture: Freely assignable outputs per channel with support for 100V lines and direct drive capability to integrate with new or existing speaker networks.

Resilience & Redundancy

• Hot Spare (N+1) redundancy: Integrated standby channel that automatically takes over to provide instantaneous failover and eliminate single points of failure.
• Dual redundant power and network: Dual 48Vdc power inputs and dual RJ45 network ports supporting A/B redundant speaker lines for fault-tolerant operation.
• Certified for life safety: Designed and certified to meet EN 54-16 and ISO 7240-16 standards for Voice Alarm systems.

Monitoring, Management & Integration

• Comprehensive self-diagnostics and monitoring: Continuous checks for short circuits, temperature fluctuations, voltage failures and speaker loop integrity using a 22 kHz pilot tone.
• Intuitive web-based management: Browser-accessible portal for remote configuration, status monitoring and scheduling of announcements with time synchronization.
• Protocol and infrastructure support: RTP, UDP, TCP/IP, FTP and compatibility with standard Ethernet (CAT5/CAT6) and fibre optic networks for seamless integration.

System Architectures

• Integrated N+1 backup system with automatic standby channel enablement and channel replacement behavior when faults occur.
• A+B host architecture: Automatic switch-over between primary and backup hosts and integrated loudspeaker loop monitoring.

Applications
Designed for mission-critical PA/VA applications where intelligibility, availability and certified life-safety performance are required, including transit hubs, hospitals and other large public or industrial facilities.
