CROWN DCi 4|300N - Four-channel power amplifier, 300W @ 4Ω with Blu Link, 70V/100V / Compliant with EN 54-16

CROWN DCi 4|300N – Four-channel power amplifier, 300 W @ 4 Ω with BLU-Link and 70 V/100 V (EN 54-16)

The CROWN DCi 4|300N integrates DriveCore™ technology into a high-performance installation amplifier with four independent 300W channels at 4 Ω and constant voltage outputs of 300W at 70 Vrms and 100 Vrms without the need for external transformers. Its BLU-Link™ digital audio engine carries up to 256 channels with low latency and, together with balanced analog inputs and a priority router, ensures signal continuity. The HiQnet™ over TCP/IP protocol enables remote network monitoring and control, while programmable GPIO ports and onboard DSP (LevelMAX™ limiters, input/output EQ, crossover, delay, matrix and line monitoring) provide maximum flexibility. It complies with the EN 54-16 standard for voice alarm systems and features front-to-back forced cooling and a universal power supply with active PFC for efficient and reliable operation.
