Isolation of Audio and Video

Any audio/video system will

achieve the best performance

when the video system is

electrically isolated from the

audio system.

The audio section of the DX-5

DSD

is completely

isolated from the video section via opto-isolators
that provide total galvanic isolation. This is unusual
and will require some extra effort to maintain this
isolation when also using other video sources.

For the best performance, all other video sources
should link to the audio system with an electrically
isolated connection to maintain isolation between
the video and audio systems. One simple and
effective method is to use the optical digital
output of other video sources. Coaxial digital
outputs can provide isolation if a transformer is in
the signal path. If you are unsure if your
equipment has built-in digital audio transformers,
external transformers are available. To isolate an
analog audio connection, the best solution is to
use high-quality transformers. Jensen
Transformers offers both digital and analog
isolation transformers.

Two-Channel Systems

For over 50 years, the vast majority of music has
been recorded in two-channel stereo, thus the
DX-5

DSD

includes two ultra-high quality audio

digital-to-analog converters. The stereo Analog
Audio Outputs will play all sources at their absolute
highest quality, including all two-channel optical
discs as well as the USB input for computer audio.

In addition, the stereo Analog Audio Outputs will
play a two-channel mixdown of multi-channel
sources, including both movie soundtracks and
musical discs. This allows the Analog Audio
