CROWN CDi 2|600BL - Analog input amplifier + Blu Link, 2 channels, 600W per output channel

CROWN CDi 4|300 – Analog input amplifier, 4 channels, 300 W per channel

The CROWN CDi 4|300 is a four-channel installation amplifier based on patented DriveCore™ technology, delivering 300W continuous per channel into 4Ω and capable of driving loads up to 100Vrms without the need for external transformers. It incorporates a powerful DSP with input router, input delay up to 1000ms, 8-band parametric EQs on input and output, LevelMAX™ crossover and limiters, all configurable from a front-facing LCD interface or via HiQnet™ over TCP/IP. Its universal power supply with active PFC and variable speed forced cooling guarantees over 90% efficiency and reliable operation in commercial and medium-sized environments such as restaurants, shops and multi-zone venues.
