Preamplifier mbl C11

Blurring the line between technology and art is the MBL Corona C11 Pre 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.

A system's musical potential can only be fully realised with the assistance of a high-grade preamplifier. MBL have invested all their expertise into the development of the Corona Line preamplifier, holding it to MBL's high-end standard. Unimpeded by any constraints, MBL have created a control centre adept with any kind of music, down to the very finest detail or each subtle change of mood or timing. To achieve this, MBL designed the Corona Line preamplifier around the best available potentiometers for acoustically perfect tracking and volume control. Their sophisticated power supply system would enhance any preamplifier. All subassemblies are carefully isolated to prevent interference that could diminish the music's nuances. MBL's uncompromising approach to development makes for superb quality and consummate musical enjoyment.

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-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). 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.
