SPDIF/AES Touch Button
This touch button allows you to set your Da Vinci for usage in
SPDIF/AES as the digital input source instead of USB. Please note,
only one input can be selected between SPDIF or AES. Also note
that when SPDIF/AES mode is selected, the real time sampling
rate display is off. Mute, Duet, and LPF modes are still functional!
Chapter 6: Special Features
Duet Mode
Our patent-pending Duet Engine uses analog interpolation to effectively double a
low sampling rate. This technology doesn’t utilize digital up-sampling, over-
sampling, or digital filters. Instead, our Duet Engine uses a sophisticated aligned
timing technology to virtually double the effective sampling rate. Think of Da
Vinci’s Duet Engine as a two-cylinder engine. Each of the cylinders is responsible
for working with the other, doubling the system’s performance and allowing
everything to run smoother. Duet Mode is especially effective when listening to a
“red book” CD’s 44.1K audio. Putting the Duet Engine to work, we can double
this into an 88.2K effective sampling rate, which gives you much smoother high
frequencies and eliminates the need for the notorious “brick-wall filter”.
LPF
Da Vinci's Low Pass Filter (LPF) is built purely in the analog domain; no digital
filters are involved. You can turn on LPF to improve the experience when
listening to low sampling frequency music sources such as 44.1k CD’s audio
files.
