Connecting and Powering the e22 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 e22 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 up to 12.288
MHz.
Connect the e22 DAC to your computer using the supplied A-B USB cable. Most standard 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 e22 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 e22 DAC to
the amplifier line inputs.
• XLR Line Outputs - Left / Right - Connect the Left and Right XLR line outputs of the e22 DAC to
the amplifier line inputs.
• XLR and RCA can be used simultaneously.
Trigger Output
When the e22DAC is on, a 12 VDC signal is sent from the Trigger Output to control other devices. When
the e22 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 e22 DAC. Amplification always brings some
level of noise and distortion. Eliminating unnecessary amplification helps to achieve higher level of
transparency.
