What can be said about Classé amps? We could mention that they are the amplification used in the legendary Abbey Road recording studio. We could also say that they are the amplification of choice for designing the new Bowers & Wilkins speakers. But here at Professional Sound & Acoustics Ltd. we believe we should say nothing and just let you listen to what the world already knows; Classé is the best you can get for your 2 channel and home theatre systems!

Delta Series

Their newest Delta series amplifiers embody all that Classé represents: innovation, technological achievement, consummate craftsmanship,and iconic design. But they are not just the latest in the distinguished line of Classé amplifiers to be launched since 1980. They are new, revolutionary and unique.

Performance first

The original Delta series amplifiers won more than critical acclaim. Elite audio professionals use them to master music and movies that the whole world has enjoyed. Their newest amplifiers are even better. Objectively, pure technical measurements prove they deliver CLASSE's highest performance ever. Subjectively, they simply blow audiences away.

The Classé design team has created the ultimate environment toamplify an audio signal. The entire amplification process occurs ona single board, creating the most direct and transparent signal pathconceivable. Our uniquely miniaturized driver stage is virtually noise free, so every nuance of the original signal reaches the output stage. Here, vast quantities of clean power are controlled with absolute precision. Suddenly, the world’s finest speakers sound even better.

Performance fast

There is a relationship between temperature and performance but it is widely misunderstood. Audiophiles say that optimal performance is obtained when an amplifier is “warmed up,” but what does this actually mean? When is it warm enough and when is it too warm? The exposed heatsink fins found on conventional amplifiers are passive. They can’t help circuits reach their ideal temperature or keep them there throughout a listening session. They run at a temperature wholly defined by their environment and how loud they are playing. This can be far from ideal.

Heat management in Classé’s new Delta series amplifiers is provided by the ICTunnel™ (pronounced Icy Tunnel), a sensor- and microprocessor- controlled technology inspired by the heatsinks found in high-power laser and medical equipment. Mounted inside the unit, the ICTunnel™ actively regulates the amplifier temperature to ensure both optimum performance and reliability.

From room temperature, the amplifiers warm up fast. They reach their ideal temperature in less than fifteen minutes and remain there regardless of how hard they are driven. No conventional heatsink can do this.

In a Class by itself 

Ground-breaking performance, prodigious power, sophisticated controland rock-steady reliability—Classé’s new Delta series is a giant leap in amplifier design. Thanks to exclusive ICTunnel™ and audio technologies, only Classé amplifiers can consistently deliver top performance and reliability in every installation

The Delta Series is available in mono, stereo and multi channel configurations so whatever your need you will find it. Whether you want to use high power mono-amps in your two channel stereo set up or whether you want to upgrade your home theatre sound, CLASSE is the sound you will need.

CT SERIES

CT  series amplifiers come with their own adjustable rack rails and a separate faceplate designed to conceal all mounting hardware along the sides of the rack. The rails adapt easily to common rack depths whileproviding front to back support of the chassis. Hidden inside, our unique Intelligent Cooling Tunnel, or ICTunnel™ (pronounced Icy Tunnel) architecture and related circuitry quietly controls the amplifier temperature, ensuring optimum performance and reliability in enclosed, poorly ventilated environments.

Conventional heatsinks are simply shaped pieces of metal, relying on placement and ambient air to extract heat from the amplifier. The ICTunnel™ is more sophisticated, acting like the human hypothalamus regulating body temperature. The ICTunnel™ utilizes an aluminum bonded-fin heatsink, of the kind used in high powered medical, laser and test equipment. It exploits the principle of low thermal mass, so it heats quickly but can also be cooled quickly. Inside its relatively small size are fins providing nearly 31 square feet of surface area. The key to its operation is how the fins are spaced—as close as possible to each other to maximize the surface area inside the tunnel, but not so close as to heat each other. The ICTunnel™ utilizes a noiseless fan along with pressure and temperature sensors to maintain the amplifier’s target temperature.

The CT series has everything you would expect from the world’s best amplifiers. They are designed for lifetime reliability. They have the power to effortlessly control the lowest impedances imaginable. They have the finesse to resolve the infinitely minute details that are the DNA of great sound. But CT amplifiers add a new dimension. For the first time the world’s best amplifiers can go right where you need them – in the home theater rack.
