Fully digital amplification
In close collaboration with some of the finest minds working in the field of digital technology, Steinway Lyngdorf has developed and advanced High End digital amplification over the past two decades. The speed, precision and incredible dynamic range of this proprietary technology took the world by storm when it was introduced in 1996, creating a musical experience against a background of completely “black” silence to enhance the finest musical details.As conventionally defined, the Lyngdorf TDAI product range does not amplify at all. They are digital-to-analog converters with sufficient power (current and voltage) to drive speakers directly, eliminating hundreds of active and passive components, which are a major source of noise and distortion.
Open loop amplifiers with zero negative feedback
In Lyngdorf TDAI digital amplifiers, signal processing is handled 100% in the digital domain, allowing pure digital processing to deliver the full musical potential. Incorporating the world’s most advanced technology, as well as uncompromising component quality, Steinway Lyngdorf creates open loop amplifiers with zero negative feedback.The Lyngdorf TDAI amplifiers employ only a single coil and capacitor to create a 60 kHz, second-order low-pass filter, following D-to-A conversion.Operating at close to 95%, cool-running efficiency, the Lyngdorf TDAI amplifiers generate virtually no heat. Requiring no heatsinks for heat dissipation, the amplifiers are extremely lightweight with a stylish, sleek exterior.To decrease volume, the output voltage of the power supply is simply reduced. This means that the volume control includes no active circuitry, making it an ideal method for uncompromising volume control.
Advantages of Steinway Lyngdorf amplification
The advantages of Steinway Lyngdorf direct digital amplification are immediately clear. The sound is stunning, clear, and articulate, with fantastic soundstage and dynamics. The dead-quiet background is an added benefit. The unusual dynamic range at lower volumes is yet another unexpected benefit of the design.Steinway Lyngdorf’s exclusive, patented digital technologies result in a musical immediacy with astounding levels of silence, transparency and naturalness. Our advanced algorithms ensure absolutely linear conversion and the highest possible audio fidelity.Steinway Lyngdorf offers a complete digital control center, incorporating an electronic crossover, D/A converter, preamplifier, power amplifier and RoomPerfect™ room correction with unconstrained sound and a sense of ultimate freedom.Among the most technologically advanced products of its kind – simplicity is the keyword for its design. All this sophisticated functionality is mounted in a compact space with passive cooling for minimum noise pollution to the environment.
Perfect sound through RoomPerfect™
One of the world’s most sophisticated solutions for adapting the sound system to the room
Most high-end products are developed in sonically-ideal listening rooms with optimized dimensions and acoustic treatments. However, in reality, sound systems are installed in authentic living spaces, not sound labs. Your sound system should be perfect in your environment—and we can promise it will be. RoomPerfect™, developed by Peter Lyngdorf, is the end product of more than two decades of pioneering audio research and development. It is an intelligent system, which not only identifies the characteristics of the sound of your speakers but also requires specific measurements of your room acoustics. It then applies corrections to the signal over a twenty-minute process that leaves you with sound that’s perfectly adapted for the shape, size, and acoustic properties of your room.
Better sound, better design flexibility
RoomPerfect™ allows you to place the speakers the way it works best for the room style. For example, if you position the speakers against the wall, you will enjoy a tighter bass and a higher efficiency from the speaker, while RoomPerfect™ will address imperfections in the frequency response related to the positioning against the wall. If you position the speakers free-standing in the room, RoomPerfect™ will address imperfections in the frequency response caused by delayed reflections from the back wall and side walls. If your room is not perfectly symmetrical in shape or furniture placement, RoomPerfect™ will address these imperfections as well. RoomPerfect™ also improves the performance of each speaker in conjunction with subwoofers. It’s very rare for subwoofers to perfectly align with the speakers – RoomPerfect™ creates a seamless blend.
The uniqueness of RoomPerfect™
RoomPerfect™ works very differently to any alternatives and provides a different level of performance and consistency. Furthermore it is quick and easy to set up and is perfect for stereo systems and home cinemas.
- Focus speaker measurement – RoomPerfect’s first measurement at the main listening seat points the microphone directly at the front speakers. Using a specifically created measurement tone, this measures the speakers with minimal additions from the room. Only by capturing this direct reading from your speakers can RoomPerfect™ preserve the performance rather than changing them to the sound the room correction system dictates.
- Room measurements – The acoustic errors a room creates are a complex three-dimensional problem. The only way they can be fully understood is by measuring all of the room in a three-dimensional way. This requires placing the microphone across the full height, width and length of the room, rather than just around the main seat. RoomPerfect™ is unique in this. Only by fully understanding your rooms acoustics and the intended response of your speakers can the system produce such high fidelity.
- RoomPerfect™ will digitally calculate the correction based on the Focus and Room readouts. It will separate the loudspeaker’s original sound from the room acoustical issues, and only correct what needs to be corrected. Room acoustical problems will be audibly removed, the bass becomes both more defined and deeper, and the soundstaging and imaging between the speakers will improve. There are three settings to chose from: Focus, for the best performance on the main listening seat; Global, for the best performance across a wider listening area; and Bypass, without any correction for comparison.
