An alluring entry to the world of high-end audio...
The mission was to achieve perfect symbiosis an ideal fusion of high-end sound with an innovative design concept. MBL teams of developers and designers worked hand in hand in engineering the concept and have broken fresh ground. The outcome is now a new range of superb high-quality high-end audio - the MBL Corona Line.

The way we listen to music at home can attain more vivid quality if each component in the system fulfills its specific task with top precision whilst working perfectly in tune with the other components. When this is achieved, we experience the breathtaking illusion of the artist standing before us in the flesh, fully captivating our attention.

It is the ideal counterpart to the Corona C11 Preamplifier, taking your sound presentation to the next level. Together they flawlessly control the loudspeakers without strain.

The Corona Line hasn't just broken the mold in design terms alone; technically speaking this new product line sets new standards. The outer solid aluminium casing contains a second casing of reinforced steel which screens off the electronics in magnetically shielded slots with full electrical isolation of the power supply units and transformers. The CD player features a state-of-the-art high-quality Slot drive and digital RCA and Toslink inputs as well as a native USB dock for CD audio data. A novel intelligent MBL SmartLink network enables the devices to talk to one another. This means that all associated input signals are controlled by the Pre-Amplifier or Integrated Amplifier and a simple touch of the button on a device or the remote control is all that you need to put the whole Corona system on standby. The power consumption is then under 1 VA (Green Standby).
