オーディオアンプ KNIPMG-600 D4

IP配電Dクラス

Product Overview
The KNTECH KNIPMG-600 Series IP Amplifier is a 600W Class-D networked public address/voice alarm amplifier engineered for high reliability in critical environments. It delivers intelligible, high-fidelity audio with flexible output architecture, integrated redundancy and comprehensive monitoring for continuous 24/7 operation.

Model & Mechanical
Model: KNIPMG-600 D4
Size: 482 (W) x 88.2 (H) x 451.6 (D) mm
Material: Aluminum / Black

Key Functional Features & Benefits

• Intelligent Power Delivery with Class-D Efficiency: 600W Class-D amplification offering high fidelity with reduced power consumption and heat dissipation.
• High-Fidelity, High-Impact Audio: Distortion < 0.5% at rated power and wide frequency response for clear, intelligible announcements.
• Versatile Output Architecture: Freely assignable output per channel with support for 100V lines and direct drive capability for easy integration with existing speaker networks.
• Hot Spare Redundancy (N+1): Integrated standby channel(s) provide automatic instantaneous failover to eliminate single points of failure.
• Dual Redundant Power & Network Paths: Dual 48Vdc power inputs and dual RJ45 network ports (A/B redundant speaker lines) for fault-tolerant operation.
• Certified for Life Safety: Designed to meet EN 54-16 and ISO 7240-16 standards for voice alarm systems.
• Comprehensive Self-Diagnostics & Monitoring: Continuous monitoring for short circuits, temperature fluctuations, voltage failures and speaker loop integrity using a 22kHz pilot tone.
• Intuitive Web-Based Management: Browser-accessible portal for remote configuration, status monitoring and scheduled announcements with time synchronization.
• Protocol & Network Compatibility: Supports RTP, UDP, TCP/IP, FTP and works over standard Ethernet (CAT5/CAT6) and fibre infrastructures.

System & Resilience

• Integrated N+1 backup system: Independent amplifier channels with integrated standby channels that enable automatic replacement when a channel fails; restored channels can be returned to service and alternates used as needed.
• A+B System support: Primary and standby redundancy for hosts; automatic switch to backup host if the primary fails; integrated loudspeaker loop monitoring.

Monitoring & Diagnostics

• Speaker loop monitoring and integrity checks via 22kHz pilot tone.
• Automatic detection and reporting of short circuits, over-temperature, voltage anomalies and other faults.
• Centralized status and fault reporting via web management interface.

Applications
Designed for critical public address and voice alarm deployments such as transit hubs, hospitals, airports and other infrastructures requiring certified life-safety audio and continuous uptime.
