Crown DCI4X1250 – 4-Channel 1250W DriveCore Install Amplifier
Product Overview
The Crown DCI4X1250 is a four-channel, 1250-watt-per-channel installation power amplifier built for demanding commercial AV environments where high output, energy efficiency, and rack-mount reliability are non-negotiable. Based on Crown's proprietary DriveCore technology, the DCI4X1250 is a primary choice for AV integrators specifying amplification for large-format distributed audio systems, house of worship reinforcement, and multi-zone commercial deployments. Its four-channel configuration supports flexible system design with full 70V/100V constant-voltage output and low-impedance operation from a single 2U rack-mount chassis.
Product Description
The DCI4X1250 is part of Crown's DriveCore Install (DCi) Analog Series, engineered specifically for permanent installation in commercial AV racks. Each channel delivers 1250 watts at 4 ohms, with support for 70V and 100V constant-voltage distribution, making it suitable for driving large speaker arrays across extended cable runs in auditoriums, conference centers, and government facilities. The amplifier incorporates Crown's patented DriveCore IC, which consolidates driver and output stages into a single chip, reducing the component count and improving thermal stability. Built-in DSP provides signal processing, limiting, and system protection without requiring an external processor for basic deployments. The front panel LCD and rear-panel control interface allow on-site configuration, while HiQnet protocol support enables integration with Harman system control platforms. The 2U rack-mount chassis is designed for high-density rack installations with front-to-rear airflow for reliable thermal management in enclosed equipment racks.
Key Features
- 1250W per channel at 4 ohms — High output power across all four channels simultaneously for large-venue commercial audio applications.
- 70V/100V constant-voltage output — Supports distributed audio systems with long cable runs standard in commercial and institutional installations.
- Crown DriveCore technology — Proprietary IC integrates driver and output stages, improving efficiency and reducing heat generation in rack environments.
- Built-in DSP — Onboard signal processing includes limiting, crossover, and delay functions, reducing external processing requirements.
- HiQnet network control — Integrates with Harman HiQnet for centralized system monitoring and control in enterprise AV deployments.
- 2U rack-mount chassis — Compact form factor allows high-channel-count amplification within standard 19-inch equipment racks.
- Front-to-rear airflow cooling — Designed for enclosed rack installation with predictable thermal performance.
- Independent channel control — Each channel configurable independently for zone-specific level, delay, and limiting.
- PureBand Flatness technology — Maintains consistent frequency response across the full audio bandwidth for accurate reproduction.
- Comprehensive protection circuitry — Guards against DC faults, overtemperature, and short-circuit conditions to protect connected speaker systems.
Typical Applications
- House of worship main and fill speaker systems
- Auditorium and performing arts center sound reinforcement
- Large conference room and boardroom AV systems
- Government and municipal facility public address
- Multi-purpose room distributed audio
- All-hands and large training room audio systems
- Commercial meeting space background and foreground audio
