Crown DCI4X600-U-USFX DCi 4|600 DriveCore 4-Channel Analog Power Amplifier, 70V/100V 600W at Ohm

Deploy reliable, professional audio for commercial, security and paging applications with the Crown by Harman DCi4X600 four-channel install amplifier. Built for integrators, this DriveCore-powered pro amplifier delivers 600W per channel (4 x 600W / 2,400W total) and flexible direct-drive constant-voltage outputs (70V/100V) so you can drive distributed speaker arrays without step-up transformers. The channel-independent Hi-Z/Low-Z selection and bridgeable channel pairs give you design freedom for lobby music, paging to multiple zones, and high-impact subwoofer feeds used in monitoring and surveillance environments.

Engineered for low operational cost, the DCi4X600 includes advanced PFC and an efficient cooling architecture that reduces rack heat and power draw—important for 24/7 security and monitoring installations. At only 2 RU tall, it delivers true rack density for smaller infrastructure rooms and easier system deployment. Backed by Crown’s reputation for durability and a 3-year limited warranty, this amplifier is ideal for pro AV integrators, security installers and facilities managers seeking dependable, high-power installed audio. Specify the DCi4X600 for your next commercial audio, paging or surveillance audio system.

• Maximize installed sound flexibility: four channels of 600W each in a compact 2 RU chassis lets you power multiple zones or distributed speaker networks without extra racks.
• Save on wiring and infrastructure: direct-drive 70V/100V constant-voltage outputs eliminate step-up transformers and allow smaller-gauge cable runs for efficient commercial installs.
• Channel-level versatility: independently select low-Z or high-Z per channel and bridge channel pairs for higher-power needs like subwoofers or stereo zones.
• Lower operating costs and cooler racks: advanced power factor correction (PFC) and efficient cooling reduce heat, energy consumption and fan noise in equipment rooms.
• Integration-ready: remote on/off and professional connectivity simplify control, monitoring and integration with security, paging and building automation systems.
