Pro-Lite Series Stereo Power Amplifier, 2025 Watts Per Channel at 4 OhmsDesigned for years of reliable, flawless operation under rigorous use, the groundbreaking Pro-LITE series utilizes an advanced design that dramatically reduces weight, while increasing output power, reliability and thermal efficiency. Pro-LITE Series amplifiers are also designed with a resonant switch-mode power supply and a highspeed class D topology, that yields the highest audio resolution and efficiency available. This revolutionary amplifier offers the sonic superiority and unsurpassed reliability for which Crest is famous, in an extremely efficient and lightweight design. Advanced technology and extensive protection circuitry allow operation with greater efficiency into difficult loads and power conditions. In other words, you get an amazingly powerful and efficient amplifier that won't break your budget or your back! The ACL (Automatic Clip Limiting) circuitry ensures trouble-free operation into loads as low as 2 ohms. ACL protects drivers and ensures that sonic integrity is maintained, even in extreme overload conditions. The Pro-LITE's high-efficiency design allows the amplifier to operate at very low temperatures, and does not require massive heat sinks to cool. For your safety, read the important precautions section, as well as input, output and power connection instructions.
Although the Pro-LITE amplifier is simple to operate and housed in an ultra-strong, ultra-lightweight chassis, improper use can be dangerous. This amplifier is very high-powered and can put out high voltages and sizable currents at frequencies up to 30 kHz. Always use safe operating techniques when operating this amplifier.
