Hegel Custom Installation Amplifier C55

Hegel C55 Custom Installation Amplifier at Vinyl Sound Toronto, Canada

The Hegel C55 is the five-channel variant of the Hegel C5 series, a range of rack-mountable multi-channel power amplifiers from Hegel Music Systems (Oslo, Norway), available at Vinyl Sound in Toronto, Canada. Delivering 150 watts per channel into 8 ohms across five channels, doubling to 300 watts into 4 ohms and 600 watts into 2 ohms, the C55 brings the full Hegel sound, including patented SoundEngine2 distortion correction and a damping factor exceeding 2,000, to custom installation, home theater, Dolby Atmos, bi-amplification, and commercial audio applications. It is the high-performance multi-channel amplifier that no longer requires a premium price to achieve a reference-grade result.

Full Hegel Performance in a Rack-Mount Chassis

The C55 carries over every core element of Hegel's amplifier philosophy into a purpose-built installation format. SoundEngine2 feed-forward distortion correction actively cancels all distortion elements generated within the amplifier circuits by replaying them in negative phase, functioning in a manner analogous to active noise cancellation. The result is THD below 0.01% at 100 watts and a naturally smooth, dynamic presentation that is never harsh or fatiguing regardless of listening level or programme material. The low-bias Class AB operating point enabled by SoundEngine2 means the C55 runs significantly cooler than conventional high-power amplifiers, making rack installation practical and safe without forced ventilation in most applications.

Built for Any Installation

The C55 is a 3U rack-mount unit with integrated rack ears and adjustable detachable rear mount ears for precise positioning in any 19-inch rack. Hegel recommends 1U of spacing above and below for airflow. Supplied feet allow free-standing placement outside a rack when required. Each of the five channels has individually switchable gain (23 dB or 29 dB) and individually switchable phase (0 or 180 degrees), simplifying integration into complex multi-zone, bi-amplified, or active crossover systems. Trigger input and daisy-chainable trigger output allow the C55 to be placed in a remote equipment room and powered on and off automatically with the rest of the system, with no manual intervention required.

Typical Applications

• Home theater stereo, 5.1, or Dolby Atmos front and surround channels
• Bi-amplification of high-performance two-channel loudspeakers
• Active crossover systems with separate bass and treble amplification
• Whole-home multi-zone audio distribution
• Commercial installations in restaurants, hotels, studios, and performance spaces
• Custom integration with Control4, Crestron, Savant, and other automation platforms via trigger control

Frequently Asked Questions

Q: What is the Hegel C55?
A: The Hegel C55 is a five-channel rack-mount power amplifier delivering 150 watts per channel into 8 ohms, part of the Hegel C5 series. It features SoundEngine2 distortion correction, a damping factor exceeding 2,000, individual per-channel gain and phase switching, balanced and unbalanced inputs on every channel, and daisy-chainable trigger control. It is designed for home theater, Dolby Atmos, bi-amplification, multi-zone, and commercial audio installations.

Q: What is the difference between the Hegel C53, C54, and C55?
A: The Hegel C5 series is available in three configurations: the C53 with three channels, the C54 with four channels, and the C55 with five channels. All three share the same chassis, SoundEngine2 technology, per-channel gain and phase control, and trigger input and output. The choice depends on channel count requirements; multiple units can be combined for larger Atmos or multi-zone installations.

Q: Can the Hegel C55 be used for a Dolby Atmos home theater?
A: Yes. A single C55 provides five channels at 150 watts each, covering a full 5.0 system. Paired with a second C5 unit, a 7.1.4 Atmos configuration or larger is straightforward to achieve. The C55's per-channel gain and phase adjustment and trigger daisy-chaining make multi-unit Atmos installations clean and manageable.

Q: Can the Hegel C55 be used for bi-amplification?
A: Yes. The C55's five independent channels with individual gain and phase control make it well suited to bi-amplifying two pairs of speakers, with one channel left for a third speaker or centre channel. Per-channel gain adjustment allows precise level matching between bass and treble amplifier sections without additional attenuation.

Q: Does the Hegel C55 run hot in a closed rack?
A: The C55 runs significantly cooler than conventional high-power multi-channel amplifiers of comparable output. SoundEngine2 enables a low-bias Class AB operating point that reduces idle heat generation, making rack installation practical in most environments. Hegel recommends 1U of clear space above and below the unit for airflow.

Q: Does the Hegel C55 work with Control4, Crestron, or Savant?
A: Yes. The C55's 5 to 12V trigger input and daisy-chainable 11.9V trigger output integrate directly with Control4, Crestron, Savant, and any other automation platform that supports voltage trigger control, enabling fully automated power management without any manual switching.

Q: Where can I buy the Hegel C55 in Toronto or Canada?
A: The Hegel C55 is available at Vinyl Sound in Toronto, Canada, an authorised Hegel dealer. Contact us to discuss system design, channel configuration, rack layout, and integration with your existing home theater or custom installation setup.
