Meet the Hegel C5 series, the most versatile high performance multi-channel amplifiers on the market. The C5 is available in three different versions, tailored to your needs. You can choose between three, four or five channel configurations, meaning you can build a 5.1 or Atmos theatre system using one or more C5 amplifiers. The Hegel C55 is the five channel version. Perhaps you want to bi-amp speakers or use active cross overs? You could also use it to power multiple speakers in a mastering studio, in a restaurant or in a home. In short, wherever you need high-performance sound with dynamics and ultra-low distortion.

As flexible as it is, the C5-series of amplifiers still maintains the full Hegel Sound. C5 uses the patented SoundEngine2 technology with its many benefits. One of them is the possibility to run low bias, meaning the high power class A/B amplifier do not run as warm as normal, allowing you to install it in a 19” rack. Another benefit of the SoundEngine2 is the very high damping factor (more than 2,000). Higher damping factor means deep, deep bass and complete control of the bass drivers. It is one of the reasons people are talking about the dynamic Hegel sound. Yet the most important is its low distortion. Hegel’s patented SoundEngine2 amplifiers work almost like a noise-canceling headphone. All distortion elements created within the amplifier circuits are dynamically canceled out, by being played back in a negative phase. So no matter how you choose to configure, the C5 series will deliver a spectacular soundstage. Never hard or unpleasant. Always natural, smooth and with incredible dynamics.

Versatility stretches further than the number of audio channels and ways to use. The ability to switch phase individually for each channel or selecting between different gain settings for each channel makes it so much easier to integrate into a larger system. The trigger input and output (allows daisy chaining) means you can place it in a separate room and never worry about switching it on or off. The C55 is 3U (rack units) tall, with massive rackmount ears that are an integrated part of the amplifier shell. When installed in a rack, we recommend 1U spacing on top and bottom. There are also adjustable and detachable rear mount ears. If you do not choose to install it in a rack, feet are supplied in the accessory box. Meaning, the C5 series can fit in any application.
