Crown CDi DriveCore 4|600 Commercial Power Amplifier [Open Box]

The Crown CDi4600 (DriveCore 4|600) is built for medium-size installations like cinemas, houses of worship, bars, and lounges that need more power per channel than the 4|300 while keeping the same 4-channel, network-controllable DriveCore platform. Each channel is rated for 600W at 4 ohms, with dual-mode operation delivering up to 600W into 8-ohm or 70V/100V loads, and bridge-mono mode combining channel pairs for up to 1200W when a single zone needs extra output.

Direct 70V/100V output means the amp powers distributed speaker lines without a step-up transformer at the output, and onboard DSP includes an 8-band parametric EQ, adjustable crossover, up to 1000ms of input delay, and a LevelMAX limiter, all pre-loaded with JBL speaker tunings to speed up commissioning. A front-panel interface handles on-site configuration, and a GPIO/AUX port lets a control system recall presets, mute channels, or cycle power remotely.

On larger jobs, the amp connects to a standard network and integrates with Harman's HiQnet Audio Architect software for centralized control and monitoring across multiple amplifiers and zones.
