The 2 RU Crest Audio Pro-LITE 3.0 Professional Power Amplifier is designed with a resonant switch-mode power supply, and high-speed class-D topology. The amplifier can be operated in parallel, stereo, or bridged mode. It features two channels with independent, fourth-order 100 Hz crossovers, and a power rating of 830W per channel at 4 Ohms stereo, and up to 3000W bridged at 4 Ohms. 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 2-Ohm 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.
