CT-5300 5 Channel Power Amplifier, 300wRms x 5 @ 8 Ohms


The Classe Amplifier CT-5300 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 while providing front to back support of the chassis. Hidden inside the Classe Amplifier CT-5300, is the 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 high-end amplifiers such as the Classe Amplifier CT-5300 use heatsinks with high thermal mass that rely on convection to cool the active circuits. They are slow to heat up and slow to cool down. Eventually they heat up their environment and as the air around them gets hotter, they become part of the problem. For this reason, high-powered amps and racks or cabinets don t easily mix.

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 of the Classe Amplifier CT-5300 utilises 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 Classe Amplifier CT-5300 from the CT series has everything you would expect from the world s best amplifiers. They are designed for lifetime reliability. The Classe Amplifier CT-5300 also has 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.
