Crown DCI4X300N – 4-Channel 300W Network DriveCore Install Amplifier

Product Overview

The Crown DCI4X300N is a 4-channel, 300W per channel BLU link network DriveCore Install amplifier designed for commercial AV systems requiring both powerful amplification and seamless network integration. Featuring Harman's proprietary BLU link digital audio bus alongside HiQnet system control, the DCI4X300N connects directly into BSS Audio Soundweb London networked signal processing environments. With 70V/100V distributed audio support and integrated DSP, it delivers a complete amplification and processing solution for multi-zone installed sound applications. This amplifier is ideal for systems architects who need tight integration between signal processing and amplification.

Product Description

The Crown DCI4X300N delivers 300 watts per channel across four independent channels, providing robust amplification for commercial installed sound systems. BLU link connectivity allows the DCI4X300N to interface directly with BSS Audio Soundweb London processors and other BLU link-capable devices, enabling single-cable digital audio transport and network control without additional interface hardware. HiQnet networking supports system-wide monitoring, preset recall, and parameter control from centralized software. The amplifier's 70V and 100V constant-voltage outputs are ideal for driving distributed loudspeaker systems in large commercial and institutional environments. Onboard DSP provides parametric EQ, alignment delay, crossover, and dynamic limiting per channel. The 2U rack-mount chassis is designed for standard 19-inch equipment racks in AV closets and equipment rooms. DriveCore amplification technology delivers exceptional power efficiency and reduced heat generation. Balanced analog inputs provide an alternative signal path when BLU link is not in use. Universal AC input accommodates global power requirements. The DCI4X300N is backed by Crown's reliability heritage and Harman's worldwide service network.

Technical Specifications

Frequently Asked Questions

What is BLU link and how does it work in the DCI4X300N?

BLU link is Harman's proprietary high-speed digital audio bus that allows direct connection between BSS Audio Soundweb London DSP systems and the DCI4X300N amplifier over a single cable, carrying digital audio and control data simultaneously.

Does the DCI4X300N require a BSS Audio processor to operate?

No. The DCI4X300N can also accept balanced analog inputs independently of BLU link. BLU link is an optional enhanced integration path for users with Soundweb London systems.

Does the DCI4X300N support 70V distributed audio?

Yes. All four channels include transformer outputs supporting both 70V and 100V constant-voltage operation for commercial distributed loudspeaker systems.

What DSP functions are available on the DCI4X300N?

Each channel has access to parametric EQ, alignment delay, crossover filtering, and dynamic limiting, providing complete onboard signal processing without requiring external DSP hardware.

How does HiQnet benefit the DCI4X300N installation?

HiQnet allows the amplifier to be monitored and controlled via Harman system management software, enabling remote fault monitoring, preset recall, and parameter adjustment from a central control point.
