Web Dashboard, Channel Trimming View for Multichannel DACs
exaSound DACs feature ZeroResolutionLoss™ hardware volume control. Audio data is streamed at 0dB
over the USB connection and volume control is implemented by the ES9018/ES9028PRO/ ES9038PRO
DAC chips. This approach preserves the maximum possible signal to noise ratio. The volume level
changes in steps of 0.5 dB.
Volume can be controlled in four ways:
•
Remotely from iPad, iPhone or Android device. Compatible apps include Roon Remote, MconnectHD
Kazoo, UPnP control points like Bubble UPnP and Hi-Fi Cast.
•
From the Gamma Music Server web interface. You can control the master volume and trim the
individual channels.
•
From the volume control buttons on the DAC front panel.
•
With the IR remote control supplied with your DAC.
The Gamma Music Server implements a unique 4-way volume synchronization. No matter which
method is used to change the volume, all volume sliders and the indicators on the DAC display and the
Gamma Music Server web interface are kept in sync.
The sound can be muted by touching the
Mute
switch on the
Dashboard
or with the IR remote control
supplied with your DAC. Pressing or clicking
Mute
again restores the previous volume level.
Note
: AirPlay devices can control the Gamma Music Server volume, however there is no volume
synchronization when volume is changed from the Gamma Music Server or the DAC. AirPlay volume
control steps are less precise compared to other audio streaming technologies.
