Seriously, the world’s most powerful & versatile multichannel IP audio codec
The highest codec density in 1U


We made your dreams come true! Our high density 1U IQOYA SERV/LINK multi-channel IP audio codec handles from 4 up to 64 stereo (8 up to 128 mono) audio input and output channels in 1U. Small and potent, IQOYA SERV/LINK can also simultaneously encode and stream the audio inputs in multiple formats and protocols, decode IP audio streams to the outputs, and transcode IP audio streams. This wonderful machine was designed for live remote broadcasting and delivery of audio programs in applications such as multiple STL and SSL links, delivery of multiple WEB radios to CDNs, multiple program delivery to DVB/cable operators, multiple live remote broadcasts, multiple intercom and commentary channels, and IP audio transcoding.What else can you ask for? Oh yes, there is more in stock: IQOYA SERV/LINK features two hot-swappable redundant power supply units, two Ethernet ports, and supports different types of audio I/Os (Analog, or AES/EBU, or MADI, or AES67/RAVENNA, or DANTE, or AES67/RAVENNA+MADI). IQOYA SERV/LINK can be fully controlled and monitored from its embedded WEB pages and through SNMP or web services.
Et voilà, it is all here, potent, versatile and reliable. Your next sidekick for live applications that require power and flexibility. 

The most versatile multi-channel IP audio codec

Possibilities are (almost) endless.


A Fully customizable Swiss army knife

The most configurable codec on the market that adapts to literally all use cases. Try it!


Maximal channel count in a minimal space

We did it: up to 128 codecs in 1U – save space and money with no compromise on channel count

Pay as you grow

Start small – if you want to. You don’t have to use all channels. Expand whenever you need.

Fully secured / 100% secure / A brick-wall security

Full isolation between the internet and the in-house AoIP network to preserve its security.

“When working on the Tokyo Games coverage, my mainhead-scratching challenge was to be able to upstream a large number of channels to Paris while using a minimal office space. IQOYA SERV/LINK is, I guess, the only codec available on the market that offers such potential with a shrunk 1U device – and this is really stunning. Besides, the connectivity addresses an extremely wide range of current standards (DANTE, etc) that definitely sounds promising for future applications”
