Description
The CDi 4|300 is a four-channel installation amplifier from the Crown CDi DriveCore series, rated at 300W per channel into 4 ohms. Each channel drives low-impedance speakers or a 70V or 100V distributed speaker line directly, with no output transformer. It suits small and medium installations such as restaurants and retail stores.
The onboard DSP comes loaded with JBL speaker tunings. Set the amplifier up from the front panel, or configure and monitor it over a standard network with HiQnet Audio Architect software.
