Description
Product Overview
The TCI TCI-2500D is a professional 2-channel Class-D digital power amplifier engineered to deliver 2x500W RMS output for commercial public address and voice alarm installations. Utilizing advanced switching power technology inside a compact 1U 19-inch rack-mountable enclosure, it offers high thermal efficiency, low standby power consumption, and dual-voltage DC battery backup.
Key Features & System Highlights
- High-Power Class-D Topology: Delivers 2 x 500W RMS through switching power supply technology, reducing rack space and heat dissipation.
- Independent Channel Processing: Features 2 discrete channels with separate gain controls, high-cut filters, and Phoenix balanced inputs.
- Flexible Output Matching: Supports both high-impedance 100V distributed speaker lines and low-impedance 4–16Ω loads per channel.
- Energy-Efficient Operation: Integrated auto-standby functionality reduces energy consumption during periods of audio inactivity.
- Comprehensive System Monitoring: Front panel LED indicators provide real-time reporting for Signal, Clip, Protection, and Output activity.
- Industrial Safety Circuitry: Comprehensive auto-protection against short circuits, thermal overload, clipping, DC offset, and current spikes.
