Streaming Audio Encoder (2001-00254)


Telos Z/IPStream R/1 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 R/1 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.

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 netcasting. There's no PC needed; Z/IPStream takes just 1RU of rack space. Slide it in and it's ready to go -- no more running your mission-critical audio over crash-prone PC hardware and operating systems. 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 Telos is the codec expert. Z/IPStream R/1 puts all our expertise into one integrated streaming appliance. First, incoming audio gets treated to pre-processing from Omnia Audio, 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 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 IP-Audio I/O. 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.
