CROWN DCi 4|300DA - Four-channel power amplifier, 300W @ 4Ω with Dante? / AES67 network audio, and 70V/100V

CROWN DCi 4|300DA – Four-channel power amplifier, 300 W @ 4 Ω with Dante™/AES67 and 70 V/100 V (EN 54-16)

The CROWN DCi 4|300DA is a high-density installation amplifier delivering four channels of 300W per channel into 4Ω (identical power into 8Ω, 70Vrms and 100Vrms) in a 2U form factor. It features Dante™/AES67 networked audio with primary and secondary ports and Dante 4.0 support for Dante Domain Manager integration, plus a high-performance DSP with JBL presets, HiQnet™ remote control and monitoring over TCP/IP, and EN 54-16 compliance for voice evacuation systems. Powered by DriveCore® technology, it offers over 90% efficiency and variable speed forced cooling that keeps operating noise below 47 dBA @ 1 m.

Product benefits

• Complete integration: Dante/AES67 and HiQnet™ over TCP/IP unify audio and control on the same network.
• High Density: Eight 300W outlets in just 2U, freeing up rack space for other equipment.
• Instant Setup: JBL presets and front panel LCD/mini buttons make setup quick without additional software.
• Critical Reliability: DriveCore® and Active PFC ensure stable, continuous performance in critical applications.
• Load Versatility: Drives 2–16 Ω speakers and 70 V/100 V systems without external transformers.

Use cases

• Public address and voice evacuation systems in airports, hospitals, and large hotels.
• Multi-zone digital audio distribution in auditoriums, convention centers, and temples.
• Corporate and commercial facilities requiring centralized control and network redundancy.

Frequently Asked Questions

• How is Dante redundancy managed? Primary/secondary Dante ports automatically fail over in the event of a failure.
• What is Dante latency? Less than 1 ms, suitable for precise synchronization of multiple channels.
• What load monitoring does it offer? Pilot tone, burst, and sweep via integrated DSP.
