Fully developed in-house, our WiSA wireless DSP amplifier transforms the Studio, Twist and Solo into superior fully digital wireless loudspeakers. But where the lossless WiSA wireless connection replaces the loudspeaker cable, to us the real benefit lies in the use of a digital crossover. An analog crossover has to abide the laws of physics that dictate, amplitude can only be reduced and that high frequencies always lead the low frequencies when arriving at the listener’s ears.
In our digital crossover however, we delay the higher frequencies to realign them with the lower frequencies. When the music is recombined at your ear, the fundamental of each note and its harmonics arrive perfectly in time, preserving the true character of each instrument. Furthermore, our crossover is implemented in front of the amplfier. It operates at lower voltage and current levels, reducing the tolerances and distortion found in analogue components. And with the ability to make any desired amplitude adjustments needed, our digital crossover is superior to any analog crossover. Compared to analog speakers you will quickly hear more control, more dynamics and more silence.
Two kinds of Wireless
Why use WISA wireless when I can just stream audio over WiFi, you ask? The Davone all-in-one music system Meander connects to the internet over WiFi and streams music with excellent stereo quality. But stereo reproduction from two seperate loudspeakers, each with their own WiFi connection, is more difficult. Now two independent music streams are downloaded. Playback can not be timed perfectly between both loudspeakers and this leads to audible shifts in stereo imaging.
WiSA is an alternative form of wireless audio that enables perfect timing for not only stereo, but also multichannel. But WiSA is different from WiFi streaming. It simply replaces the loudspeaker cable with a dedicated wireless transmitter and receiver. An external source of music needs to be connected to the WiSA transmitter. If this were to be a music streamer, now again only one music stream is downloaded, solving the timing issue faced by multiple Wifi streamers playing stereo.

How does it Work?
The Davone module consists of 3 major elements. First, the blue PCB, designed in house, houses the microcontroller (a) which is the brain of the Davone module. It's reliable memory contains all the DSP (b) digital cross over FIR algorithms and many functional tasks like setting the DAC digital filters and temperatur monitoring. The high performance 32 bit Velvet Sound AKM Delta Sigma DAC (c) is handling the conversion to analog. The power is supplied by ultralow noise linear regulators and ample capacitance of different types for a virtual battery like performance. The Low jitter Quartz Crystal Oscillator originates the clocking with a jitter less than 100ps rms.The fully balanced output stage minimises noise and is connected directly to the balanced input of the latest generation ICE power amplifier (d). Last but not least, the audio input to the system is supplied by the WiSA wireless receiver (e). Note the four F shaped antennas on the 4 corners for excellent reception in the 5gHz band.
Eye for Detail
High frequency digital signals above 1 MHz, like for example the master clock, need to be routed carefully to maintain high signal integrity. Ideally the connections should be short and direct, but often this is not possible because another signal line crosses it’s path. Textbook four layer print design would divert the trace through a so called via to the bottom layer to cross the obstacle. The second and third layer are used for the ground and power supply planes and therefore already occupied. However, in high frequency circuit design it is vital to keep the distance between the forward and return current traces at a minimum (the path of least inductance). It is therefore much better to route the forward current through the third layer instead of the fourth. That way the return current only has to switch sides on the second layer instead of also jumping planes through one extra via with possible added ground plane noise as a consequence. The improved high frequency current flow is shown in the image above and explained below.
Crystal clear sound
The Quad core DSP enables independent corrections of amplitude and phase, impossible in analog speakers. Aided by the ASRC and low jitter clock, the data is processed at least at 96kHz/24 bits throughout, finally to be converted to analog by the ultra low distortion AKM DAC with balanced outputs.
ICEPower Class D
ICEpower amplifiers combine superior sound quality with high continuous output power. And by connecting it direct to the individual loudspeakers, the high signal quality is fully maintained. A step up compared to analog loudspeakers.
Dolby Atmos Multichannel
If you’ve ever wanted a true 5.1 or 7.1 surround system, but have hesitated because of the wiring requirements, WiSA is for you. The WiSA SoundSend enables Dolby Atmos and lower versions decoding.
Connect to all TV's
The WiSA SoundSend HDMI-ARC input can be connected to virtually every TV manufacturer out there, including B&O, Sony, Samsung and many others. The TV remote will also change the loudspeaker volume.
Some WiSA transmitters come with Chromescast and Airplay 2 built in, making it possible to create a multiroom system with virtually every sound manufacturer out there, including B&O, Sony, Bose and many others.
A Wireless Standard
WiSA is the growing standard in wireless audio transmission, with support from more than 60 manufacturers including LG, Toshiba, Klipsch, and Bang & Olufsen. In other words, Wisa enables wireless connections between audio products from different brands.
