The TDAI-2170 fully digital integrated stereo amplifier combines the celebrated performance of the Lyngdorf Audio brand with superior technology that’s second to none.
Equipped with proprietary RoomPerfect™ room correction technology, the TDAI-2170 is a user-friendly component offering two channels and 170 watts of power, as well as optional upgradeable modules to provide a modern addition to any listening environment.
Pure sound, advanced room correction, and the signature Lyngdorf Audio black styling? Well, hello there.
Why room correction? In any audio system, more than 50% of the sound you hear comes from the contribution of the room—echoes, reflections, absorption, and the like.
The solution to this problem is RoomPerfect™, the most advanced room adaptation software available. RoomPerfect™ uses sophisticated technology to adapt the sound system to the environment, rather than the other way around. It assesses each room and adjusts your speakers to account for the specific physical characteristics of the environment, making them sound exactly as the manufacturer intended them to, not the way your room’s limitations make them sound.
That might seem a tall order for a sexy little amplifier—but the mighty TDAI-2170 delivers. It’s tested. It’s proven. And it works.
With the TDAI-2170, nothing gets between you and your sound. You will find no digital-to-analog conversion in the TDAI-2170; the digital signal drives the speakers directly, with no translation and no middleman. The signal follows an unbroken fully digital signal path without sound-deteriorating conversions. What does that mean for you? This unique and technically demanding solution offers noiseless replay at all sound levels, an unsurpassed dynamic range, and the purest sound possible.
Whether used with full range, satellite, in-wall, or on-wall speakers, the TDAI-2170 is the perfect choice for any brand or model on the market. Because of its unique technologies, the long-contested challenge of speaker placement no longer compromises performance. On the contrary. Simply place your speakers up against the wall to get the least amount of damaging reflections. From there, RoomPerfect™ will adapt the speaker to the room and remove any unwanted bass boom.
Have a subwoofer? Not a problem. RoomPerfect™ perfectly aligns the subwoofer and speakers’ frequency response, so differences between peaks and dips in the bass and midrange responses are eliminated. Now, your entire system is integrated and singing. 
When music is being mastered, the level is often very high; upon analysis you will often find several consecutive maximum samples, indicating something has been clipped away from the original signal. Audio that exceeds 0 dBFS (decibels relative to full scale) will sound very compressed because the headroom is nonexistent. Sadly, this harsh sound is often related to digitally stored music, as compared to the sound of vinyl. 
With ICC (Inter-sample Clipping Correction) the TDAI-2170 will handle digital signals as high as +12 dBFS. As it on-the-fly adjusts the signal level through the converters, you will enjoy the full dynamic range and a distortion free sound.
It’s a complex world out there—but the TDAI-2170 can take it on. With an optional HDMI module (ARC/CEC compatible with four inputs and one output), the TDAI-2170 is a smart addition to your existing A/V system. Plus, the TDAI-2170 offers optional streaming USB audio in. You can even go all the way with an optional high-end ADC (Analog to Digital Converter) supplementing the standard analog inputs. Keep it simple or max it out—the options are all yours.
The TDAI-2170, like all Lyngdorf Audio products before it, is a masterpiece of substance and style. The amplifier’s chassis—a salute to modern industrial design—is built like a tank and dressed in the signature black finish fans of Lyngdorf Audio love. The design is complemented with black glass and aluminum in a sleek profile that complements any décor.
