I will not reply to lowballs or "is this still available"
No known Issues. No visible damage.
Note: Battery cover on remote is missing (Not the battery contacts, which still hold the batteries in place, but the plastic cover itself)
The Microphone xlr cable for room perfect May have issues…intermittent. Microphone works when plugged in to amp, but having some recent issues when using the extension cable.
From Lyngdorf:
The TDAI 2200 true digital integrated amplifier is the most versatile amplifier in our range and in the world. The standard version of the compact 2 x 200W digital control centre can be expanded with analog input module and the outstanding RoomPerfect room correction system.
The TDAI 2200 is a fully digital amplifier from Lyngdorf based on the experience gained during the design of the new Millennium platform. The TDAI 2200 is much more than an amplifier, it is a complete digital signal processing control centre for designing advanced audio systems based around active loudspeakers. Active meaning use of active cross-overs instead of ordinary passive filters.
And don't let the actual size of the product deceive you. The compact design of the TDAI 2200 features a powerful amplifier capable of driving difficult loudspeaker loads effortlessly. Also integrated within is a DSP section with equalization and correction possibilities for speaker position and delay, combined with extreme versatility with regard to processing, making this amplifier an obvious choice for the critical audiophile.
This product replaces simultaneously a D/A converter, a pre-amplifier and a power amplifier, requiring only a CD transport as a source. The TDAI 2200 is full of remarkable features like the adjustable power supply voltage which actually works as the volume control. This ensures you full dynamic range - even when playing at very low volume levels.
Power Supply and Volume Control
The Lyngdorf true digital amplifiers are based on non-feedback construction, which means there are no differences in the THD performance at any frequency when it comes to the output stage. In other words, the distortion is very low and linear. However, another major influential factor to the THD performance of a fully digital amplifier is the quality of the power supply. With the Lyngdorf power suppliers we have obtained completely identical and very low impedance which gives a completely flat THD at all frequencies. This is simply a necessity for a high performance implementation of a true digital amplifier.
The power supply uses a toroidal transformer and the advantage of this over a conventional C or El core transformer is significantly less magnetic radiation, something which can potentially induce noise (50/60Hz) which would be very audible. The supplies for the output stage and the microprocessors are kept completely separate since they use separate windings on the transformer.
The result of this truly unique way of controlling the volume level is that a Lyngdorf true digital amplifier gives full dynamic range from maximum volume and down to the 62dB reading in the volume control (which corresponds to as little as 1V RMS on the speaker terminals). This is due to the fact that when the supply voltage to the output stage is reduced, then you lower both the output signal AND the noise floor - and thus the full dynamic range is maintained - also at low volume levels. Perhaps this is one of the reasons why reviewers often mention that Lyngdorf amplifiers play equally well whether you're playing at high or low volume levels.
