Connecting and Powering the e28 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 e28 DAC accepts three
digital inputs
• USB - This is the recommended and most capable input. It supports 2 to 8 channels PCM and
DSD. PCM is supported with 32 bit resolution at standard sampling frequencies from 44.1 kHz to
384 kHz. DSD sampling rates range from
2.8224 MHz to 12.288. Connect the e28 DAC to your
computer using a standard A-B USB cable.
• 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 e28 DAC offers one of two types of analogue line outputs - unbalanced (RCA) or balanced (Mini-
XLR):
• Make sure that your analogue power amplifier is turned off.
• RCA Line Outputs 1 to 8 - Connect the line outputs of the e28 DAC to the amplifier RCA line
inputs.
or
• XLR Line Outputs 1 to 8 - Connect the Mini- XLR line outputs of the e28 DAC to the amplifier XLR
line inputs.
Trigger Output
When the e28 DAC is on, a 12 VDC signal is sent from the Trigger Output to control other devices. When
the e28 returns to Standby, the trigger signal is discontinued.
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 e28 DAC. Amplification always brings some
level of noise and distortion. Eliminating unnecessary amplification helps to achieve higher level of
transparency.
