Crest Audio Pro-LITE 3.0 Power Amplifier

Crest Audio Pro-LITE 3.0 Power Amplifier

The Crest Audio Pro-LITE 3.0 is a two-channel Class D power amplifier.

A switch-mode supply keeps the amplifier’s weight low. It provides amplification for passive PA speakers and subwoofers in sound reinforcement systems.

Each channel offers full-range, high-pass or subwoofer operation with a 100 Hz crossover. This allows separate channels to feed subwoofers and mid/high loudspeakers.

Front-panel attenuators set input levels. Five LEDs per channel report active status, signal, ACL limiting, temperature and DC protection.

Main Features

• Automatic Clip Limiting reduces severe clipping as the amplifier reaches its output limit.
• Balanced XLR/TRS inputs connect to mixers and loudspeaker processors.
• Locking speaker outputs help prevent accidental cable disconnection.
• Independent channel filters support separate frequency bands within a system.
• Protection covers temperature, DC, incorrect loads and under/overvoltage conditions.
• A variable-speed fan adjusts cooling to operating temperature.
• Separate attenuators make it possible to set independent loudspeaker levels.
• Bridge and parallel-input modes offer additional system configurations.

Who Is It For

For passive loudspeaker systems where amplifier weight matters. This is the non-DSP version; connected loudspeakers must stay within the stated total load limits.
