OPERATION
MACINTOSH - USB
Open the System Preferences panel on your Mac. You will find it under the Apple menu at the
top left of your desktop. Once open, you will see an icon labeled “Sound” on the second row.
Click that icon to enter the audio setting area. From the three tabs at the top of the sound
window, select “Output”. Select “C-Media USB Headphone Set. “This is the driver that OSX uses
for USB audio output. Selecting this device will route audio to your DAC-100 or DAC-100t using
USB.
MACINTOSH - OPTICAL
If you plan to use an optical input connection, you will need a standard Toslink cable. On some
Apple computers and devices (MacPro, Apple TV), this Toslink cable will plug directly into the
optical port on the device. Some devices, like the Airport Express and Macbook computers, can
connect optically but require a mini-plug adapter. Your local Apple store can help you with this
adapter.
Selecting this input is much the same process as when using USB. Navigate to the “Sound”
control panel as described above. Under “Output”, you will see “Digital Output” as an option.
Selecting this device will route audio to the DAC-100t using the optical digital connection.
MACINTOSH – AUDIO MIDI SETUP
Macintosh computers have a utility for adjusting how audio is handled on the computer. This utility
is called Audio MIDI Setup and is located in the “Utilities” folder. Settings for default input and
output devices are set here, as well as certain parameters for the device in use. To check or adjust
the settings for the DAC-100 or DAC-100t, select “C-Media USB Headphone Set” from the
“Properties For” menu when using a USB connection. On the right side of the window you will see
details of the audio output settings of the DAC-100 or DAC-100t. Under this output section, you
can adjust the output frequency from 44.1kHz to 48kHz. Adjustments to the bit depth of the audio
can also be adjusted here from 16 to 24 bit.
PC CONNECTIONS
It is required you select a high performance media player, one that is capable of high resolution
audio at various sampling rates for hi-resolution playback.
Prior to installing, be sure you have downloaded or copy the Streamlength v126s (or later) driver
software from our website onto your desktop.
NOTE:
• When installing the Streamlength v126s driver software on some Windows 8
computers, Windows 8 may not recognize the installer for the driver. If this happens
you must run the driver installation in compatibility mode.
