CROWN CDi 1000 - Two-channel power amplifier, 500W @ 4Ω, 70V/140V

CROWN CDi 1000 – Two-channel power amplifier, 500 W @ 4 Ω, 70 V/140 V

The CROWN CDi 1000 is a versatile and lightweight (approx. 10 kg) 2U rackmount installation amplifier designed for commercial and AV applications. It delivers 500 W continuous per channel into 4 Ω and directly drives 2 Ω, 4 Ω, 8 Ω, 70 V and 140 V loads without external transformers. Its active PFC switching power supply and mono bridge mode switch enable up to 1,400 W into 4 Ω . It features integrated DSP with crossovers, EQ filters, delays and limiters, as well as an intuitive front-facing LCD display for quick setup. With up to 20 user presets and remote monitoring via HiQnet™, the CDi 1000 combines power, control and reliability in a compact package.
