Crown CDi DriveCore 4|300 Commercial Power Amplifier [Used]

The Crown CDi4300 (DriveCore 4|300) extends the 2|300's DriveCore design to four channels, giving small and mid-size commercial installs like restaurants and retail stores more zones from a single amplifier. DriveCore technology strips out hundreds of components found in traditional amp designs, which cuts down on variability between units and supports long-term reliability in continuous commercial use.

Each of the 4 channels drives 300W at 4 ohms and can output either 70V or 100V directly, powering distributed speaker lines without a step-up transformer at the output. Onboard DSP includes an 8-band input and output parametric EQ, adjustable crossover, up to 1000ms of input delay, and a LevelMAX limiter to protect connected speakers, and the amp ships pre-loaded with JBL speaker tunings to speed up commissioning. A front-panel interface handles full configuration on site, while a GPIO/AUX port lets a control system recall presets, mute channels, or power the amp on and off remotely.

For larger installs, the amp connects to a standard TCP/IP network and can be controlled and monitored through Harman's HiQnet Audio Architect software, giving visibility across multiple zones and amps from one interface.
