continue the unbroken Crown tradition of leadership in professional and commercial power amplifier technology.

Features

• 

Exclusive DriveCore Technology  – The patented DriveCore integrated circuit combines hundreds of discrete circuits 

into one chip for better performance, lower power consumption and improved reliability.

• 

Power Saving Modes – Power consumption in sleep mode is less than 1W. 

• 

Auto Standby – Amplifier goes into Sleep mode after 30 minutes of no input signal. 

• 

Remote Power Off – Sleep mode activated via AUX port.

• 

70 V / 100 V Direct Drive – Each channel individually selectable for low-Z or high-Z operation.

• 

100 V Direct Drive Capability – Higher voltage allows more speakers per output and reduced wiring costs.

• 

TLC Protection – Protects amplifier from excessive heat and maintains operation by intelligently applying gain reduction when necessary.

• 

Advanced Protection Circuits – Amplifier and loads are protected against shorted outputs, DC, mismatched 

loads, overheating, over- or under-voltage, and high frequency overload.

• 

Three Year, No-Fault Transferable Warranty – Your investment is fully protected.

• 

Complies with Green Edge by Harman – Environmentally friendly practices in design, manufacturing, and packaging complement energy-efficient operation.
