Legacy Audio Wavelet II DAC/Line Stage/Crossover/Room Correction


The Legacy Audio Wavelet II is a control preamp, a high-end DAC, a 2/3/4-way digital crossover with time alignment and a speaker correction system that will literally “learn” your room.

“You immediately hear more detail with virtually every recording, and a cleaner and more natural soundstage. The ability to make firmware upgrades will lead Legacy and Bohmer to make steady improvements in processing, operating, and set-up features, and don’t forget, as you look at the price, the Wavelet is also a really good analog and digital preamp and DAC as well. The combination of the Aeris and Wavelet provide some of the most musically realistic sound I’ve ever encountered.” – Anthony Cordesman, The Absolute Sound

In an ideal world you would hear the music exactly as it was intended to be heard. But rooms are not perfect and resonances play havoc below 500Hz. The Wavelet II DSP processor will analyze your room and make the calculations to reduce resonant energy as late as 40msecs. The improvement in tonal balance and pitch defnition is not subtle.

Already have a favorite DAC with a volume control? How about a big vinyl collection? Analog lovers can take advantage of balanced XLR or unbalanced RCA inputs without concern of digital artifacts. An apodizing circuit corrects for the the pre-ringing native to CODECs. Wavelet II has adequate headroom to handle these higher level signals while functioning as a crossover and compensating for room resonances. Wavelet II processes at 56 bits of depth in a domain more than one trillion times finer in resolution than that of a standard CD.

The Wavelet II is by design upgradable. The unit can download firmware updates directly when you choose.

Setup is simple, and the Wavelet II is easily controlled with the included App that runs in your iPad/iPhone/Android or other smart device. Wavelet comes with a precision calibrated microphone and a wifi adapter that allows you to work wirelessly with the Wavelet.

Wavelet II easily integrates in any system.
