Features
The e20 DAC is based on the ES9018 Sabre
32
reference DAC chip. It delivers 32-bit precision capable of
resolving the smallest signal details. The chip features patented 32-bit Hyperstream™ architecture and
Time Domain Jitter Eliminator. ES9018 delivers the industry’s highest performance levels that will
satisfy the most demanding audio enthusiasts.
Windows ASIO Driver Advantages
Using ASI brings unique advantages that are hard to achieve and reliably verify with other Windows
driver technologies.
Automati Sampling Rate Swit hing
PCM data is always streamed without re-sampling. Native Windows 7 drivers often require manual
sampling rate selection and may apply implicit re-sampling when the source rate differs from the rate
set in the Windows Control Panel.
Automati PCM / DSD Swit hing
Audio data is always streamed in its native format. e20 switches automatically between PCM and DSD
modes. DSD streams are processed in their native format without conversion to PCM.
Bit-perfe t operation independent from the Windows volume ontrol and mixer
The Windows volume control and mixer are optimized to provide wide compatibility and easiness of
use. These features come at the expense of sound quality. The resulting output is not bit-perfect or bit-
transparent. Third party proprietary Windows drivers are hard to be verified as bit-perfect because
factors beyond the control of the user can change the Windows sound processing chain.
ur proprietary ASI implementation is completely independent from the Windows sound system and
always operates in Exclusive Mode. nly one player can take control of the ASI driver. When playback
starts the player sets the driver sampling rate to be the same as the native rate of the current media file.
The sound data stream is delivered to the e20 FIF memory buffer without any processing or
manipulation.
Asyn hronous USB mode eliminates jitter aused by the PC or the USB interfa e
Asynchronous USB is a two-way communication method between a computer and an external USB
device. In this method, the USB device is running as a master, and the computer is acting as a slave that
delivers data only when requested by the master.
In the case of the e20 DAC, sound data is requested by the FPGA core and stored in the device FIF
memory buffer. The FPGA core makes sure that the buffer never gets empty during playback. Data from
the buffer is streamed to the DAC chip. The precision of the timing of the output stream is determined
only by the DAC oscillators and it is not degraded in any way by the PC clocks or by delays caused by the
USB interface.

Connectin and Powerin the e20 DAC
Before connecting, turn off the power to all the components in your system.
Connectin the Di ital Inputs
All digital inputs are galvanically isolated to eliminate ground loop noise. The e20 DAC accepts three
digital inputs
• USB - This is the recommended and most capable input. It supports 2 channels PCM up to 32 bit
resolution at standard sampling frequencies from 44.1 kHz to 384 kHz, and DSD from 2.8224
MHz to 12.288 MHz (e20 MK III).
Connect the e20 DAC to your computer using the supplied Mini A-B USB cable. Most standard
Mini A-B USB cables with length up to 6 ft (2m) can be used.
• SPDIF IN1 - SPDIF Input, 75-ohm RCA. Supports 2 channels PCM up to 24 bit resolution at
standard sampling frequencies from 44.1 kHz to 192 kHz.
• SPDIF IN2 - SPDIF Input, T SLINK, ptical. Supports 2 channels PCM up to 24 bit resolution at
standard sampling frequencies from 44.1 kHz to 96 kHz.
Connectin the Line Outputs
The e20 DAC offers two types of analogue line outputs - unbalanced (RCA) and balanced (XLR).
• Make sure that your analogue power amplifier is turned off.
• RCA Line Outputs Left / Right - Connect the Left and Right RCA line outputs of the e20 DAC to
the amplifier line inputs.
or
• XLR Line Outputs Left / Right - Connect the Left and Right XLR line outputs of the e20 DAC to
the amplifier line inputs.
Direct Connection to Analo ue Power Amplifier
If your music sources are digital, you don't need a preamplifier. The built-in volume control allows
analogue power amplifiers to be connected directly to the e20 DAC. Amplification always brings some
level of noise and distortion. Eliminating unnecessary amplification helps to achieve higher level of
transparency.
Avoid connecting the
e20
DAC to receivers and any other sound processing equipment
that performs analogue to digital (ADC) conversion. Digitizing the analogue output signals
back to the digital domain for processing will undo the benefits that e20 brings to you.
Remember that your sound system is as good as the weakest link in the sound processing
chain.

Page | 12
Analo ue Interconnect Recommendations
ver-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.
Connectin 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 between
the components.
Using an Upgraded Power Supply
The e20 DAC comes with a 12V/1200mA 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.
Sur e Protectors
We strongly recommend the use of surge protectors for all of your audio and video components.
Isolatin 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.

Remote Control Setup
The e20 DAC is pre-programmed to work with the supplied remote control. If you like, you can
reprogram the e20 DAC to work with a different IR remote control. The exaSound e20 DAC can be
trained to recognise commands from most infrared remote controls using Sony and NEC IR protocols.
Use the following procedure to change remote control button assignments or to pair the e20 DAC with a
