Power On/Off
• The e28 DAC has an automatic power-on function and it will turn itself on when playback is
detected.
• The e28 DAC automatically turns itself off after a period of inactivity. Use the Power Off Timeout
setting to adjust the inactivity time interval before shutdown.
Volume Control
The e28 DAC volume is controlled by the ES9018 DAC chip. It is independent from the Mac software
volume control and it preserves the maximum possible signal to noise ratio.
The volume level changes in steps of 0.5 dB. At first power on, the volume level is set to match the
volume level of your Mac. If the DAC is not connected to your Mac, when turned on the volume level is
set to -40 dB.
Use the volume sliders in the Audio MIDI Setup window to control the volume for individual channels
and the master volume.
The master volume can also be controlled from the device front panel or using a remote control. When
the master volume level is changed, the value displayed on the Mac screen and on the device front
panel display are synchronised.
Volume Bypass
When the volume sliders for the exaSound driver in the Audio MIDI Setup application are set to 0dB, the
hardware volume control is turned off and the e28 DAC operates in Volume Bypass Mode.
To activate Volume Bypass:
• Set the master volume slider to 0dB.
• Set the left and right volume sliders to 0dB.
• Make sure that your player is not changing the volume level.
