Z/IPStream combines audio processing with MP3 and AAC encoding in one convenient, single-rack unit. The AAC encoder supports AAC-LC, HE-AAC and HE-AAC v2 formats, and is fully managed and configured remotely with any standard Web browser. Z/IPStream features a wideband AGC, 3-band compressor/limiter, EQ, low-pass filter and a precision look-ahead final limiter; processed audio can then be encoded directly to MP3 or AAC streams to feed a remote replication server at your ISP. Streams can be “tagged” with “now-playing” information received from automation systems. Analog and Livewire® I/O are standard.

Plug. Play. Stream.
For years, the way to stream audio to Internet listeners included unbalanced mini-jacks, poor-quality sound cards, one or more PCs to maintain, and a collection of software that didn’t always play nicely together. Broadcasters asked for a professional, PC-free Web streaming solution — and Telos delivers.
Z/IPStream R/1 takes the hassle out of streaming. There’s no PC needed; Z/IPStream R/1 takes just 1RU of rack space. Slide it in and it’s ready to gostreaming. Just send audio to Z/IPStream R/1, make a few setup selections and, within minutes, you’ll be streaming your programming to your favorite stream server or streaming service for worldwide distribution.
Broadcasters know that Telos is the codec expert, and Omnia is the processing authority. Z/IPStream R/1 puts all of our expertise into one integrated streaming appliance. First, incoming audio gets treated to pre-processing from Omnia, using algorithms that work hand-in-glove with Z/IPStream R/1’s codecs to shape and optimize audio prior to encoding. Then, genuine MPEG encoding algorithms from FhG, the inventors of MP3, ensure the most artifact-free sound quality at whatever bit rate you choose. Encode directly to an MP3 or MPEG-AAC stream, then send it to a Shoutcast, Wowza, Icecast, LimeLight, Akamai, Adobe Flash Media server, or other popular streaming server for distribution to your waiting listeners.
Setup is a breeze. Log in with a laptop and Web browser for easy setup or remote control, or tweak the front-panel controls. There’s also a convenient built-in headphone amp with 1/4” jack and volume control for last minute in-the-rack fine tuning.
Z/IPStream R/1 comes with studio-grade analog inputs and outputs, plus Livewire Audio over IP. On the output side, Z/IPStream R/1 delivers fully processed, unencoded audio as well as encoded audio, providing your studio with another source for processed sound. Full network connectivity is provided via two Ethernet jacks, one for the LAN (including Livewire) and the other for the WAN and streaming.
The Professional Choice for Streaming Audio.
Optimizing sound quality is as essential on the web as it is on traditional formats. Z/IPStream R/1 has a built-in processing section that works together with the streaming encoder, optimizing your audio for stunning sound — even after bit-reduction. This isn’t just some cheap leveler – it’s real processing by Omnia, complete with wideband AGC, a 3-band combined compressor/limiter, high-frequency EQ, an adjustable-bandwidth low-pass filter, and Omnia’s famous anti-aliasing final Look-Ahead limiter. There are even a selection of presets, tailored to specific formats and bit rates, to help you get up and running quickly.
Of course, the foundation for high fidelity audio distribution rests on professional encoding technology. The quality of the encoder directly affects the quality of the output. Telos has a long history of partnership with Germany’s Fraunhofer Gesellschaft Laboratory (FhG), the world leader in audio compression research and the inventors of MP3; Z/IPStream R/1 uses genuine MP3 and MPEG-AAC encoding algorithms to ensure the most artifact-free sound quality at any bit rate you choose, from 16 kbps all the way to 320 kbps. No other encoder has this pedigree, or achieves this level of quality and performance. Generic “mp3” encoders can’t come close.
Z/IPStream R/1 gives you a wide choice of genuine Fraunhofer encoding algorithms, which include MP3, the Standard for digital audio. It’s the safest codec choice for compatibility with the widest variety of listening devices. Or choose AAC-LC, a high performance codec for excellent audio quality at lower bitrates. AAC-LC is in widespread use, most notably in Apple’s iTunes. And then there’s High Efficiency Advanced Audio Coding, or HE-AAC, a newer AAC codec which incorporates Spectral Band Replication (SBR) bandwidth expansion to improve audio at very low bitrates. HE-AAC v2 applies a Parametric Stereo feature to HE-AAC codec allowing for even further reduction in bandwidth.
When you’re done processing and encoding, select your metadata source and feed your stream to any SHOUTcast or SHOUTcast v2-compatible media server, or a Wowza server for streaming to Flash clients. Z/IPStream R/1 works with ICECast and Adobe Flash Media and Adobe RTMP servers too, as well as popular streaming services from LimeLight, Akamai, and other popular streaming service providers. You can feed directly to a streaming server on your LAN, to an Internet streaming relay service via the WAN port, or take processed audio from the rear-panel XLR outputs. No matter what your audio source or how you stream, Z/IPStream R/1 delivers flawlessly optimized audio that sounds terrific.
