  The audio engineer’s amplifier wish list? Abundant power, a compact and elegant chassis, clean lines with dynamic shape, and energy efficiency to satisfy the most ecologically minded homeowner. Can such attributes exist in an audio amplifier? They already do in the MBL C15 monoblock. This MBL audio component can go into Green Standby at the touch of a button, with the C15 consuming less than 1 VA. But don’t be deceived. Capable of unleashing 500 watts of output in an instant, the sleek, high-end C15 is ideally suited to satisfy the demands of any speaker without missing a beat, thanks to LASA – MBL’s Linear Analogue Switching Amplifier technique. This proprietary technology ensures a composed, serene performance is maintained while delivering a warm yet detailed sound with extremely low distortion across the frequency range. Even in the largest of listening rooms, the C15 can pair with a broad range of speakers to deliver unruffled, vivid natural sound.
  It’s not magic…it’s LASA
  MBL’s LASA amplifier technology combines the best capabilities of traditional Class A and Class AB amplifiers with the efficiency of switch-mode topology. LASA delivers the homogeneous THD curve of Class A operation, the stable frequency response (even with complex loudspeaker loads) of Class A / B circuits, and the high efficiency of a class D amplifier. The result is a power amplifier circuit that remains completely poised even under very complex loudspeaker loads. LASA delivers a live-in-studio experience of captivating sound that immerses every listener in a musical wave of notes, timbres and melodies. Quell your thirst.
  LASA/LASA 2.0
  The best of all worlds – amplified

  MBL’s Linear Analogue Switching Amplifier (LASA) is a proprietary circuit technology that brings together what belongs together, the most sought-after features from different amplifier concepts.

  In an ideal world, every amplifier would be a device of simple function and pure character. Like a magnifying glass, it would simply enlarge music signals without omitting, adding, coloring or bending even the most delicate of sounds. And its power supply would be put to use for the benefit of the music alone – not to warm up the listening room with excess heat.

  The world, however, is not ideal. Some amplifiers seem to produce more heat than power, but are capable of enchanting their listeners with rich, studio-quality sound. Other amps deliver a full performance and stay cool, but may sound frosty, rather than sunny; brittle rather than welcoming.

  So, does amplifier technology really have to compensate for every advantage with a corresponding trade-off? Not at MBL, where our developers’ answer to this question is the Linear Analogue Switching Amplifier – better known as LASA. This ground-breaking amplifier concept combines high-energy efficiency with a sound quality that is simply captivating. MBL introduced LASA technology in 2011 with the debut of its Corona Line of amplifiers. Several years later, LASA 2.0 was presented to the world in MBL‘s Noble Line family of amplifiers.

  Amplifier technology – a class system
  The audio world defines the circuitry principles of conventional amplifiers by letters of the alphabet, with different letters representing distinct properties.

  For example, a specific skewing of the music signal, commonly known as artificial harmonics or distortion, is an unwanted addition to the music. Class A amplifiers do not produce any such crossover distortions; they deliver homogeneous distortion characteristics, consistently low across all frequencies of the music signal, even at different volumes. Their function is also largely independent of the electrical properties of the connected loudspeakers. This behaviour has a great effect on the sound, but comes at a cost. Class A amplifiers draw substantial amounts of power and convert a significant portion of it into heat. As such, they require large heat sinks to dissipate this wasted energy, along with plenty of ventilation space on all sides so that ambient air can freely circulate.

  Class AB amplifiers work in Class A mode only when the volume levels are low. When the sound level is turned up they switch to the more efficient Class B operation, which uses electrical power more efficiently and produces less heat. Their consistent amplification at all pitches – technically speaking, their linear frequency response – does not change with the properties of the connected speakers. The drawback to this amplifier class is instances of crossover distortion, where the distortion changes depending on the frequency and power. Audio experts’ rule of thumb is that Class AB amplifiers tend towards non-linear distortion, but depending on the volume intensity, this can disrupt one’s musical enjoyment.

  Class D amplifiers, also known as “switching amplifiers,” are even more efficient. Not even five-alarm party volumes can get them hot. Their compact housing remains, at most, warm to the touch, but their distortions can vary with the pitch of the music, and their harmonic distortion factor is non-linear. They’re also designed to work with the specific resistance value of the connected speakers in mind – a value of 4 ohms for example. But the AC resistance (impedance) of loudspeakers varies with the frequency of the music. In the case of Class D amplifiers, this can lead to fluctuations in the frequency response, and overtones in the treble range.

  The challenge? Is it possible to combine the musical beauty of the Class A amplifier with the stability of the Class AB group and the enormous practical benefits of Class D amps? The answer is a definitive “YES,” and MBL has found it with LASA. LASA amplifiers harness various independent technologies to produce music with a lightness that allows emotional connections. Catchwords like “confident” or “relaxed” are often used to describe the LASA effect in listening test reports. Why is this?

  The laboratory litmus test – overcoming complex loads
  Conventional measurements and standards fail to explain the complex ingenuity behind LASA technology’s capabilities. According to accepted laboratory audio standards, when an amplifier runs at maximum capacity, there’s a measured resistance between the audio system‘s loudspeaker terminals – typically with resistance values of 4 ohms or 8 ohms. But in the real world outside of the lab, the amplifier has to deal with loudspeakers which perform nothing like a well-behaved measuring resistor. The coils and capacitors in the crossovers, and the loudspeaker chassis itself, not only alter the resistance depending on the frequency, but they also react in a lively and unpredictable manner to the phase position (the temporal relationship between current and voltage). Taken together, those complex electrical “interactions” can decisively fluster a power amplifier.

  Through the development and integration of its own proprietary measurement scheme, MBL’s LASA technology precisely simulates complex loudspeaker loads in all possible situations, including the mythical four-quadrant test (4QT). The 4QT measurement diagrams show that LASA amplifiers are able to effortlessly drive loudspeakers with many different electrical properties. With LASA 2.0, the latest development of this successful concept, MBL has further optimized its technology in order to provide musical playback that is always stable, powerful, and brilliantly transparent.
