The 2RU Pro-LITE 3.0 Professional Power Amplifier from Crest Audio is designed with a resonant switch-mode power supply and a high-speed class D topology. The amplifier can be operated in parallel, stereo, or bridged mode. It features two channels with independent, fourth-order 100Hz crossovers and a power rating of 830W per channel at 4Ω stereo, and up to 3,000W bridged at 4Ω. The robust power supply is designed to allow the amplifier to deliver a consistent, stable performance with low frequencies. The Pro-Lite amplifier is built with heavy-duty circuit boards and extra-large capacitors and inductors designed to optimize 2Ω operation. The on-board 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. It also features DC, Temp, Signal, and Active safeguards, all referenced on the front panel with LED indicators.
