Cool-Amp Series

High Efficiency Class-D Amplifiers

The ZypherLABS Cool-Amp Series Amplifiers are a turning point, and a breakthrough in the Indian Pro-Audio Industry.

The Cool-Amp series amplifiers are designed to work tirelessly in the harsh operating environments in India – Hot Weather, Unstable Mains Voltage, & Overloaded Operation. These Amplifiers outshine their rivals while driving high-current 2 ohms loads continuously, even in the hottest Indian weather.

The Cool-Amp Series by Zypher Labs is designed with a clear objective of a “No Compromise” High-Performance Audio, with Rock-Solid Reliability – two of the most important requirements for the demanding live sound touring applications.

COOL-AMP Series Features

Very High-Efficiency (96%) Pulse Width Modulation (Class-D) technology almost eliminates cooling requirement and allows continuous 2Ω operation in 45° weather.
Zypher Labs Patented (FFT™) (Filtered Feedback Technology), & optimized layout to minimize switching noise, provides Sonic Performance which rivals High-End Class-A amplifiers with the efficiency of Class-D.
The Cool-Amp series Amplifiers are Optimized for driving demanding 2Ω. These amps are “Built for 2Ω not just 2Ω Stable”.
A three stage Speaker Protection system provides maximum possible protection to the Speakers in the event of a fault.
Full set of Amplifier Protections, including DC Offset, Short Circuit, Auto-Ramp, Soft Start, Thermal, Bus Pumping, Over-Current & Clip Monitoring
Low-Voltage operation down to 170v.
Conventional Toroidal Transformer power supply increases reliability through simplicity, and allows large current draw without tripping..
German Semiconductors, with double current headroom for increased reliability.
