AMX

AMX NCDI1000 audio component 2-channel amplifier

SKU CH-33R2-1E74R MPN NCDI1000

Two-channel professional amplifier delivering 500 W per channel at 4 ohms with onboard DSP, LCD configuration and 70 V/140 V output options

  • Delivers 1000 W RMS across two channels
  • Drives 2, 4, 8 ohm and 70 V / 140 V loads
  • Front LCD screen simplifies system configuration
  • Onboard DSP handles crossovers, EQ, delay and limiting
  • Universal switch-mode supply runs on any mains voltage

Professional installed-sound amplifier

The AMX NCDI1000 is a two-channel Crown CDi Series amplifier built for permanent installation in commercial venues, houses of worship and education spaces. It delivers 1000 W RMS total output and operates from a universal switch-mode supply. The unit is designed for integrators who need reliable, configurable power in a compact rack format.

Load flexibility and signal performance

Each channel is rated for 500 W into 4 ohms and also supports direct 70 V and 140 V constant-voltage lines without external transformers. The amplifier accepts 2-, 4- and 8-ohm loudspeaker loads. Full rated power at 8 ohms requires a 1.4 V input signal, and the signal-to-noise ratio reaches 100 dB A-weighted. Frequency response extends from 20 Hz to 20 kHz at 1 W.

Front-panel configuration with DSP presets

A built-in LCD screen walks the installer through gain, crossover, EQ, delay and limiter settings without a computer. Up to 20 user-defined DSP presets can be stored and recalled locally. Phoenix-style input connectors and barrier-strip outputs simplify wiring, while proportional-speed fan cooling and short-circuit protection reduce thermal and fault-related service calls.

Questions about this item

Should I choose the 4-ohm or 8-ohm load rating for my speakers?

The amplifier is rated for 2-, 4-, and 8-ohm loads and also supports 70V and 140V distributed line outputs. Select the setting that matches your speaker impedance or line voltage system.

What does the 1000 W RMS rating mean for actual output per channel?

The unit delivers 500 W per channel into 4 ohms in stereo mode. The 1000 W figure represents total RMS power across both channels combined.

How does the 1.4V sensitivity spec affect gain staging with my mixer?

The amplifier reaches full rated power at 8 ohms with a 1.4V input signal. Set your mixer output level to match this sensitivity for optimal headroom and signal-to-noise performance.
