Designed 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.
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.
