The Sigma 2200i display will show the status of the audio stream, so when
using AirPlay, it will show the sampling frequency of the signal as well as its
format (ALAC is the format AirPlay streams use). You may adjust the volume
in iTunes or if using Apple’s free Remote App, change volume and choose and
manage music files from your iOS device (iPad, iPhone, iPod touch). Volume
changes are actually made in the Sigma 2200i so it volume display will change
in response to changes you make in iTunes or with the Remote App. If you press
pause or stop, the display will indicate AirPlay - Idle.
Using an iOS device for AirPlay works the same way. Choose the Music App
icon, tap the AirPlay icon, select the Sigma 2200i from the list of AirPlay
speakers, choose your music and play. Volume is likewise adjusted in the Sigma
2200i by using the volume control on the device.
DLNA
If you have chosen a Media Player other than iTunes and/or wish to stream
higher bit-rate files (up to 192 kHz), the Network connection will use the
DLNA protocol. As with AirPlay, simply setup a source button to use the
Network connection. You can stream audio over this connection whether DLNA
or AirPlay, so you only need to enable a single Network connection to have
access to streaming audio from multiple sources.
DLNA is structured around three basic elements: a Media Player, a Renderer and
a File Server. The Media Player is your control interface. It is a program or App
that could reside on a smartphone, tablet or computer and its job is to allow you
to access your music files and control their playback. Examples of popular Media
Players include JRiver, Twonky and Media Monkey. A File Server is where your
audio data files are stored. Your Mac or PC could be the file server or it could
be an outboard storage device such as a NAS (Network Attached Storage) drive.
When called to be played, the data transit the Network from the file server,
through the Ethernet cable into the Sigma 2200i, which is a Renderer. It decodes
the file, performs any DSP functions you require and converts the audio from
digital data to an analog waveform. It then sets the playback volume and outputs
the signal to your amplifier(s).
The setup of a system for using DLNA can become more complex than an
iTunes/AirPlay system and because of the nearly endless combinations of
hardware and software that may be involved, it is beyond the scope of this
manual. You will need to supply and configure the software for your chosen
DLNA Media Player and DLNA server(s). A Computer Audio Set-up Guide
which provides additional information is available on the Classe website. If you
need assistance, your Classé dealer should be able to help.
