fi ™ BLUETOOTH IMPLEMENTATION
Bluetooth modules are a fantastic and convenient way in which to share and listen to music from online and mobile sources. It’s not unusual for companies to use such modules as a complete end-to-end or add on solution whereby using the cheap low-grade onboard DAC chips included in the modules and simply passing the analog signal of the module to the analog output section. Our solution is to fully integrate (fi™) the digital information of the CSR aptX® lossless Bluetooth receiver into the entire digital circuit of the DMS-500. This approach ensures that Bluetooth sources have the potential to sound like any other expensive input source whereby utilizing our sophisticated digital topology of parallel DACs and our other integrated digital features such as; TruBit™ Upsampling, and OSO™ Reclocking. Now your Bluetooth sources can truly be high fi .
TruBit™ DSD & PCM Upsampling
Upsampling can be messy, leaving behind lots of digital artifacts resulting in noise and inaccurate signal generation. On the surface, upsampling may seem like a good idea. But if not implemented properly it can be disastrous. Many DACs use modest DSP chips at best, or worse, the DAC chip itself to upsample all incoming digital signals. Typically, this is done as a predefined one - size - fits all sample rate, such as 96 kHz, 384 kHz, etc. On the contrary, Cary Audio’s TruBit™ Upsampling is a sophisticated and powerful process utilizing a dedicated 128 bit DSP engine which allows for up to 10 different selectable TruBit™ sample rates and an increased bit depth of 32 bits. Working in tandem with our OSO™ Reclocking feature, the newly generated signal is cross-checked multiple ways ensuring that the selected upsample rate is as if it were an original native signal. The result is a signal free from digital artifacts that sounds accurate, pure, and a joy to listen to.
PCM TO DSD CONVERSION
Within the TruBit™ Upsampling the DMS-500 can convert any PCM inputs to true DSD256 output. Now with PCM to higher PCM, or PCM to DSD upsampling even the most strident of PCM and DSD proponents can have their cake and eat it to. PCM to DSD conversion takes our TruBit™ technology to whole new level of pure silky smooth analog like sound like never before from digital sources.
OSO™ RECLOCKING
Once a digital signal is transferred into Cary Audio’s digital ecosystem via the digital inputs, it is processed with extreme care to ensure the best possible sound achievable. As a digital source transfers from one point A to point B it creates an insidious digital problem called ‘jitter’. To deal with this, Cary Audio uses something we call OSO™ Re-clocking. This solution re-clocks all signals again once onboard as to ensure all jitter is virtually eliminated to a minute degree. We call this OSO™, short for “Onboard Signal Origination” because this re-clocking and buffering creates a signal so stable and jitter free it’s as if the origin of the signal was generated onboard and not from an external source.
