CROWN CDi 2|300 - Analog input amplifier, 2 channels, 300W per output channel

CROWN CDi 2|300 – Analog input amplifier, 2 channels, 300 W per channel

The CROWN CDi 2|300 is a two-channel installation amplifier based on DriveCore™ technology, delivering 300W continuous per channel into 4Ω and capable of directly driving loads up to 100Vrms without the need for external transformers. It features a high-level DSP with input router, delays up to 1000ms input and 100ms output, 8-band parametric EQs on input and output, a crossover, and the LevelMAX™ limiter suite for loudspeaker protection. A front-facing interface with LCD display and dedicated buttons makes commissioning easy, while monitoring and remote control are provided via HiQnet™ over TCP/IP. Ideal for small to medium-sized installations such as restaurants, shops, or houses of worship, with pre-configured JBL presets to speed up setup.
