Analogue Interconnect Recommendations
Over-engineered interconnects made from exotic materials are unnecessary. When selecting cables, the
following characteristics are important:
• Reliable electrical contact
• Low resistance
• Robust mechanical design
Remember that cables act as filters. The shorter the cable, the more transparent your system will be.
Connecting the Power Adapter
To minimize ground noise and hum, it is recommended to connect the power cords of all components to
a single point - usually a single surge protector with multiple outlets. Connecting all components to a
single point, as close as it is practically possible minimizes the differences in ground potentials among
the components.
Using an Upgraded Power Supply
The e20 DAC comes with a 12V/1670mA power adapter. This power adapter has been
tested to comply with the DAC’s power supply and quality requirements and allows for
very high performance. A better unit may allow you to squeeze the last bit of performance
from the e20 DAC. Please be advised that using a different power supply than the one
included in the package may void the warranty.
If you decide to use another power supply, the specifications marked on the back of the
e20 DAC must be observed.
Surge Protectors
We strongly recommend the use of surge protectors for all of your audio and video components.
Isolating the Cable TV Ground
If you have a cable TV connected to your audio system, ensure that the TV cable ground is galvanically
isolated from the audio system ground. The TV cable ground, usually connected to the earth outside
your home, can have a significantly different potential than the audio ground. This condition can cause
audible hum. If you suspect this is the case, use a cable TV ground isolator just before the cable set-top
box or at the RF TV input.
When turning on and off your music system, the power amplifier should be the last
component to be turned on and the first component to be turned off. This prevents
power on/off transients from being transmitted to the loudspeakers.
