2.2 Getting started
This section contains brief instructions to get you up and running quickly. If you need more detailed
instructions, see the Installation procedures section.
First, install the software onto your Windows PC or Mac if necessary:
A USB drive is shipped with your Callia, which contains software to be installed on your Windows PC
or Mac. Note that no software installation is required for use with Linux-based PC, player, streamer
and server devices.
If you intend to play audio from a Windows PC via USB, you MUST install this software since it
contains a UAC2 driver to allow Windows to send audio to Callia. If you don't intend to play from a
PC, but only want to play audio from a Mac via USB, or via one of Callia's S/PDIF inputs, you don't
need to install any software and you can skip to the next section...
... however: we still recommend that you install the software on your Windows PC or Mac since this
will allow you to install future firmware updates, but you can install the software later if you like.
· DO NOT connect the Callia unit to the computer via USB until AFTER software installation is
complete.
· To install the software on a Windows PC, allow the USB drive to auto-run, or else double click on
setup.exe in the root of the drive.
· To install the software on a Mac, double click on the .pkg file in the root of the USB drive.
· In either case, a series of dialogue boxes will guide you through the process.
Next, connect up your Callia:
· Connect an audio source: either an S/PDIF source via Callia's optical (TOSLINK) or RCA S/PDIF
input, or else a Windows PC or Mac host computer (USB cable provided). If you're using a
Windows PC, make sure you remembered to install the software in the previous section.
