Turn Your PerfectWave DAC into a Music Server
Access your home network and the Web with the PS Audio PerfectWave Bridge. The Bridge is the link between the home network and your high-end audio system. It is a custom designed PC board that slides into the back of a PS Audio PerfectWave DAC. Under the hood is an incredible high-resolution 192 kHz, 32-bit capable network interface with innovations and technological breakthroughs galore.
The Bridge lets you access and play digital music files on your home network, but that's just the beginning. It also allows you to listen streaming audio on the Web, including Pandora and Rhapsody. It gives you access to thousands of Internet radio stations, too. And you wirelessly control these and many other functions via your iPod, iPhone, or iPad.
Unlike Anything Ever Built to Date
The Bridge is unlike anything ever built to date. Instead of a 'quasi asynchronous' clocking system found in most systems we have investigated, the Bridge is a true asynchronous parallel 32-bit system approach. This means that there are actually two low jitter isolated and separate clocks (44.1 kHz and 48 kHz) that are completely unrelated to any other clock in the Bridge for true asynchronous performance.
There is also no digital manipulation of any kind going on in the Bridge, either through sample rate converters or DSPs. While many manufacturers rely on system-wide clocking and digital manipulation to lower jitter and improve performance, the PerfectWave Bridge provides low jitter I2S music without any digital manipulation, and the differences are easy to hear. The PerfectWave combo is simply stunning.
Up to 32-bit, 192 kHz Resolution
The bridge contains all the CODECS (programs) to convert just about any format of audio into what the PerfectWave DAC wants for perfection, which is I2S. Once the Bridge gets a network music stream, it figures out what the native format is (FLAC, WAV, ALAC, MP3, etc.) and converts the format into a pure digital audio stream without any associated clocks. This is important because this data, once converted to its raw format, can then be placed into the 256 mB memory of the 'Digital Lens' and then output in I2S directly into the DAC.
The I2S format has separate clocks and data lines that never mix with each other and therefore there is little to no jitter. The Bridge can accept any format with resolutions up to 192 kHz, 32 bits and feed that info directly into the PWD for sound that simply takes your breath away.
Control the Bridge with iPod, iPad, or iPhone
The Bridge allows PerfectWave DAC owners to enter the world of connected audio. You aren't tied to a computer. You can store your music anywhere in the house (as long as there is a network), you can connect either wirelessly or wired, and you'll be having more fun with your collection than you have in years.
The controller is the interface between your stored library of music and the Bridge. It lets you scroll through everything in the library, create playlists, read cover art, artist's bios, etc. Using Apple's extremely affordable iPod Touch, iPhone, or iPad, you can download PS Audio's TagNPlay app from the iTunes store. Scroll through your music library, find something you want to hear and simply touch the song title. The system immediately begins to play, setting the correct sample rate and filter setting automatically.
TagNPlay will also control every feature on the PWD, including sample rate, phase, filters, inputs and volume. Cover art and artist's bio are sent over from the PS Audio servers automatically as long as your network is connected to the Internet. Everything just happens without anything required from you.
Using the Apple based controller gives you a number of advantages such as full access to internet radio, including PS Audio's own eTracks radio station offering great, commercial free high-resolution programming into your home.
What's Inside the Bridge?
The Bridge is based on 32-bit architecture with the core processor running at 500 MHz and using 256 Mb of high speed DDR memory for the lens. The data is clocked out of the DDR memory into a custom CPLD (Complex Programmable Logic Device) that organizes each of the 32 bit frames into the requisite I2S format. That I2S data is then clocked out of the CPLD with one of two custom, low jitter, fixed frequency asynchronous clocks (depending on the sample rate) and finally leaves the Bridge and into the PerfectWave DAC through high speed buffers powered by a separate supply in the DAC.
The majority of the few connected audio streaming devices on the market today are based on either a small PC type motherboard or off-the-shelf microprocessor based solutions with integrated clocks and little to no control over the way the data is handled and manipulated. With very few exceptions, these solutions do not come close to the performance of the PS Audio PerfectWave Bridge. |
