Crown CDi 4|300BL DriveCore Amplifier with BLU link

The CDi 4|300BL puts 300 W behind each of its 4 channels and drives 70Vrms or 100Vrms distributed lines straight from the output, so a medium install skips the step-up transformer entirely. Crown aims the CDi DriveCore line at cinemas, houses of worship, bars, and meeting rooms, where the amplifier gets racked once and then has to be left alone.

Onboard DSP handles crossover, EQ, delay, and limiting, and the line ships pre-loaded with factory JBL speaker tunings so a common loudspeaker can be dialled in from the front panel rather than a laptop session. A BLU link digital audio bus carries channels in from a HARMAN network, which replaces a bundle of analog runs with one digital link, and network control and monitoring are onboard.
