Crest Audio PRO-LITE 2.0 Ultra-Efficient Lightweight High Power Amplifier (Discontinued)

Description

Details

The Pro-LITE™ 2.0 DSP power amplifier features an incredibly lightweight, efficient design with high power and stable performance -- plus built-in DSP. The Crest Audio Pro-LITE 2.0 DSP amplifier is designed with an advanced, high-speed class D design with a switch-mode power supply that reduces weight while increasing reliability, thermal efficiency and output power in parallel, stereo and bridged modes. The Pro-LITE 2.0 DSP boasts two channels with independent, fourth-order 100 Hz crossovers and power ratings of 540 watts per channel at 4 ohms stereo (up to 2,000 watts bridged @ 4 ohms).

A robust power supply allows these amplifiers to deliver consistent, stable performance with low frequencies. The Crest Audio Pro-LITE 2.0 DSP features an onboard digital signal processor that hosts a suite of delays (0-120ms per channel), adjustable crossovers, adjustable limiters, parametric EQ, HF driver EQ, four user preset storage locations, and stereo/mono operation with lockable security settings. The front-panel LCD screen allows users to quickly identify and assign presets, while the USB port allows users to load presets and enables external setup and adjustment. The Pro-LITE DSP section also integrates Waves® MaxxBass® Bass Extension technology, which uses psycho-acoustics to create precise harmonics that give the perceived effect of boosting low frequencies in the mix. The level of MaxxBass effect can be adjusted from 0% to 100%. Pro-LITE Series power amps are built every bit as strong and solid as audio pros expect from Crest Audio, with heavy-duty circuit boards and added emphasis on mission-critical components like extra-large capacitors and inductors that optimize 2-ohm operation. The onboard protection suite includes Crest Audio's proprietary ACL™Automatic Clip Limiting circuitry, which prevents the amplifier from sending potentially damaging clipped signals to the loudspeakers, as well as DC, Temp, Signal and Active safeguards, all referenced on the front panel with LED indicators. The Pro-LITE Series is backed by a free five-year extended warranty.
