Application
An equalizer can be used to correct or "flatten" the frequency response of speakers rather than
designing the speaker itself to be equalized. Some speaker systems don't use separate woofers and
tweeters to cover the bass and treble frequencies but rather include full-range drivers. However, this
speaker system is sold with an active equalizer designed to correct the poor frequency balance of
those drivers. That equalizer must go into the sound system before the amplifier so that the
amplified signal is sent to the speakers. The signal has its response increased at the frequencies
where the response of these drivers falls off, producing a high fidelity reproduction regardless. Ateis
audio processors give you the same solution without using an external equalizer, it's all done in the
software component PEQ.

Ethernet IGMP Audio Stream
This component is an Internet stream player which receives audio stream and play the streaming source.
The Internet audio stream which sends the audio streaming from the devices such as PC or Terra device,
and compose into the certain RTP format (Real-time Transport Protocol) and play the audio stream via this
component. For example, TerraServer can be the source to stream audio to this component. The
supported format are inlcuded PCM(16K 16Bit Mono), G711ulaw, G711alaw, G722 and MP3.
Note: IGMP address 224.0.0.0~224.0.0.2 is reserved, which can not be used as the IP of IGMP
address.
224.0.0.0: Base address(reserved).
224.0.0.1: For all the hosts on the same network segment.
224.0.0.2: For all the routers on the same network segment.
Note: The [Ethernet IGMP Audio Stream] component will occupy with 1 x message channels, please
