The Crown CDi 2|600BL DriveCore Power Amplifier is a professional 2-channel, 600-watt-per-channel amplifier designed for commercial and installed sound systems requiring reliable amplification, advanced digital signal processing, and network connectivity. Featuring Crown DriveCore technology, BLU link digital audio networking, and direct-drive 70V/100V outputs, the CDi 2|600BL provides a flexible solution for powering distributed loudspeaker systems.
Designed for houses of worship, cinemas, restaurants, bars, hotels, and commercial facilities, the CDi 2|600BL delivers 600 watts per channel at 4 or 8 ohms, as well as 600 watts per channel in 70V or 100V operation.
Unlike conventional amplifiers that require external output transformers for high-voltage distributed audio systems, the CDi 2|600BL directly drives compatible 70V and 100V speaker lines. This simplifies installation while reducing the need for additional equipment.
The amplifier also includes BLU link connectivity, allowing digital audio to be transmitted and received across HARMAN's BLU link audio network. Ethernet-based control and monitoring through HiQnet Audio Architect software provide installers with convenient access to amplifier configuration, DSP settings, and system status.
With integrated DSP, preloaded JBL loudspeaker tunings, and an intuitive front-panel interface, the Crown CDi 2|600BL combines powerful amplification with the control and flexibility required for modern commercial audio installations.

Flexible Amplification for 70V, 100V, and Low-Impedance Speakers
The Crown CDi 2|600BL supports both conventional low-impedance loudspeakers and distributed audio systems.
For commercial installations using multiple ceiling or wall-mounted speakers, the amplifier can provide direct 70V or 100V output without requiring external step-up transformers.
Each channel delivers up to 600 watts in 70V or 100V operation, making the amplifier suitable for distributed sound systems in restaurants, hotels, retail facilities, and houses of worship.
The amplifier also supports 2Ω, 4Ω, 8Ω, and 16Ω speaker configurations, giving installers flexibility when designing systems around different loudspeaker requirements.
BLU link Digital Audio Networking
The CDi 2|600BL includes BLU link, distinguishing it from the standard CDi 2|600 amplifier.
BLU link provides digital audio connectivity for compatible HARMAN professional audio equipment.
The amplifier can send and receive audio channels over the BLU link network, reducing the need for multiple analog audio connections in larger installations.
This makes the CDi 2|600BL particularly useful in systems incorporating compatible BSS, Crown, and other HARMAN BLU link-enabled equipment.
Advanced Digital Signal Processing
The Crown CDi 2|600BL includes onboard DSP for precise control over audio performance.
Available processing functions include:
-
Input routing
-
Input delay up to 1,000 ms
-
8-band input parametric EQ
-
Crossover processing
-
8-band output parametric EQ
-
Output delay up to 100 ms
-
Crown LevelMAX limiting
These tools allow installers to optimize frequency response, configure loudspeaker crossovers, manage signal timing, and help protect connected loudspeakers.
The amplifier also includes factory-loaded JBL speaker tunings to simplify configuration with supported JBL Professional loudspeakers.
Ethernet Control and System Monitoring
The CDi 2|600BL supports network-based configuration and monitoring through HARMAN HiQnet Audio Architect software.
Using a standard TCP/IP network connection, installers can access amplifier settings, monitor operating conditions, and make system adjustments remotely.
The front-panel interface also allows configuration directly from the amplifier.
For additional integration, the GPIO/AUX port supports external control functions such as preset recall, channel muting, and fault monitoring.
