TYPE: Stereo Power Amplifier

The mission was to achieve perfect symbiosis – an ideal fusion of high end sound with an innovative design concept. MBL’s 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 Corona Line’s minimalist design is a new byword for restrained understatement combined with classical elegance which makes it the perfect match for almost any type of room. The Corona Line takes its name from the 40mm button shaped like the MBL logo and mounted on the upper side in a corona of light. This signature button serves to regulate the brightness of the display. All products in the range have been carefully coordinated to complement one another and when taken together as a single family unit radiate an atmosphere of truly captivating serenity.



The Corona Line hasn’t just broken the mould in design terms alone; technically speaking too 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 supplies 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-Amplifi er or Integrated Amplifi er 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).

The MBL Corona Line is a fully rounded statement of our proven expertise in audio engineering and design – a consummate fusion of perfect acoustics and design. A truly alluring entry to the world of high end audio.
