Volume Bypass with exaSound DACs
When the volume is set to 0dB, the hardware volume control is turned off and the Gamma Music Server
sets the exaSound DAC in Volume Bypass Mode. To activate Volume Bypass:
•
On the web interface set the master volume to 0dB.
•
Set the left and right volume sliders to 0dB.
•
If you are using a multichannel DAC, set all channel sliders to 0dB.
Maximum Volume Limit
Use the
Maximum Volume Limit
setting to prevent accidental playback at volume levels that are too
loud.
UPnP Server and Music Library
The exaSound Gamma Music Server has a built-in UPnP server. It works with music files stored on
attached USB drive or on the internal SSD storage. Playback is controlled with apps like MconnectHD,
Bubble UPnP, Hi-Fi Cast, Kazoo and others.
Gamma Music Server supports direct connection of up to two USB 3.0 hard-disk drives (HDD) or solid-
state drives (SSD). Up to eight USB drives can be connected to the Gamma Music Server using an
external powered USB 3.0 hub.
The UPnP server scans attached USB drives and the internal SSD storage for audio files. Metadata from
the discovered files, like album, artist, and cover art are organized in media library which is stored on
the internal SSD storage.
When an USB drive is attached for the first time to the Gamma Music Server, or when music files are
added or removed, you have to update the UPnP library. From the web user interface, go to
Settings
page and on the UPnP Music Library tab click the
Update
button. Scanning large USB drives may take a
while.
Before connecting a USB drive to the Gamma Music Server, make sure to empty the Recycle Bin/Trash
Can. The Gamma Music Server may find and include in the media libraries files that are not permanently
deleted.
See
Sharing Attached USB Drives on the Network
for instructions how to copy files over the home
network to the Gamma Music Server.
To avoid accidental data loss we recommend powering down the exaSound Gamma Music
Server before disconnecting a USB drive. Always maintain a backup copy of your music
files. Never disconnect a USB drive during playback.
