Connecting and Powering the e20 DAC
Before connecting, turn off the power to all the components in your system.
Connecting the Digital 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, TOSLINK, Optical. Supports 2 channels PCM up to 24 bit resolution at
standard sampling frequencies from 44.1 kHz to 96 kHz.
Connecting 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 Analogue 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.
