Crest Audio Pro-LITE 7.5 Power Amplifier
The Crest Audio Pro-LITE 7.5 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.
- Variable-speed fans adjust cooling to operating temperature.
- Separate attenuators make it possible to set independent loudspeaker levels.
- Thru outputs pass input signals on to another amplifier.

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.
