FEATURES
The following section describes the DMC-600 and DMC-600SE’s basic features. Please read the
Operation Section of this manual to learn more on utilizing these features. The features are subject to
change without notice or obligation.
MULTIPLE PARALLEL DAC TOPOLOGY
While the DAC chip(s) are a piece to the overall solution in creating a reference level digital source
machine, it’s just one part of a very complex puzzle. As DAC chips become smaller and more
powerful with multiple channels per DAC and onboard processing, one could design a good
product utilizing perhaps just one chip, maybe two chips, as many do. For the DMC-600 and
600SE, good wasn’t good enough. We choose to use 3 DACS consisting of 6 channels, 3 channels
per side. This makes for an outstanding product. This configuration is a fully balanced parallel
circuit feeding both the balanced XLR and single-ended RCA outputs for exceptional clarity and
detail.

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 DMC-600 (600SE). This approach ensures that
Bluetooth sources have the potential to sound like any other expensive input source whereby
utilizing our sophisticated digital topology of multiple parallel DACs and our other integrated digital
features such as; TruBit™ Upsampling, OSO™ Reclocking, and DiO™ selectable tube or solid state
outputs. Now your Bluetooth sources can truly be high

TruBit™ 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 I2S and SPDIF digital signals. Typically, this is done as a
predefined
one-size-fits-all
sample rate, such as 96 kHz. 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 7 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 upsampled 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.
