KRK Enhances KNS Headphone Range KRK HAS STRENGTHENED its studio-quality headphone offering with the new KNS 6402 and KNS 8402. Building on its KNS 6400 and 8400 headphone models, KRK enhances the durability and comfort of its headphone offerings with these updated models. Delivering an accurate listening experience in a high-performance package, KNS 6402 and 8402 headphones are suitable for studio tracking, editing, mixing, or for any general listening applications.

With a closed-back circum-aural (around the ear) design, both the KNS 8402 and KNS 6402 headphones offer a comfortable listening experience to support music producers through long studio sessions, without any fatigue. Also, the headband features a self-aligning yoke system to ensure the best possible fit. The KNS 6402 model features acoustic cellular foam pads and provides up to 26 dBA of isolation with a 122 dB maximum SPL rating and a frequency response of 10 Hz-22 kHz. The KNS 8402 headphones feature memory foam pads with premium leatherette covers, offering superior comfort during long hours of listening and recording sessions. The KNS 8402 headphones provide up to 30 dBA of isolation to block out even more external noise and feature a slightly higher SPL with a 124 dB maximum SPL rating and a frequency response of 5 Hz-23 kHz. They also feature a cable with in-line volume control, further enhancing the user experience and providing a complete spectrum of volume level options. Visit

Grass Valley and Telos Partner on Cloud-based Intercom IN PARTNERSHIP WITH the Telos Alliance, Grass Valley is releasing Telos Infinity VIP (Virtual Intercom Platform) on its GV AMPP (Agile Media Processing Platform). A professional intercom solution for cloudbased media production workflows, Infinity VIP on AMPP supports essential intercom functionality, including partylines, IFBs, groups and peer-to-peer communication. This new cloud-based production functionality is being beta-tested by USbased OB company All Mobile Video (AMV) and will be live with an AMV customer later in the year.

those flight cases hundreds or thousands of miles; and if requirements change on a production, we have instant access to whatever is needed. All of this is made possible with the cloud by ‘spinning up’ what we need when we need it,” said Eric Duke, CEO, AMV.

“With GV AMPP, every solution is current, this means that we no longer have to amortise equipment; we don’t need a warehouse full of kit in flight-cases; we don’t have to move

With Infinity VIP on AMPP, operators supporting live productions from anywhere can access the application from any connected browser. The microphone and

Telos Infinity VIP on AMPP is a native SaaS solution tightly integrated from both an operational and commercial standpoint for a frictionless experience. The Infinity VIP on AMPP cloud server and virtual panel apps are available from the AMPP app store and deploy in the same way as any AMPP application.

speakers from the connected phone, tablet, or computer allow operators to communicate with team members, while using the same device for performing their job functions using other AMPP-enabled solutions such as switching, audio mixing, replay, routing, and monitoring. Usage monitoring is consolidated with other AMPP applications to provide a single billing experience. While providing the latest in flexible user interfaces, this new intercom solution also provides cloud connection for existing intercom hardware, providing all the benefits of a new cloud-enabled system while retaining existing intercom infrastructure and workflows.

IP Audio Decoder for Radio Broadcasters


BARIX HAS ADDED TO ITS RANGE OF Exstreamer audio over IP codecs with the launch of the Exstreamer M400 IP audio decoder.


The Exstreamer M400 features stereo, linelevel, analogue audio output with RCA-type connections and can decode streams in MP3, AAC-HE, FLAC, PCM, Opus, and Ogg Vorbis formats. Newly added AES67 support enables the Exstreamer M400 to instead be configured as a dedicated AES67 receiver and decoder, enabling seamless integration into AES67-based audio-over-IP networks plus interoperability with Dante-compatible devices. The Exstreamer M400 incorporates the full AES67 interoperability guidelines including RTP audio delivery, multicast addressing, and PTP-based synchronization with a separate master clock device.

Supported discovery methods include SAP (Session Announcement Protocol), mDNS (multicast DNS), and RTSP, enabling the decoder to automatically identify and list available streams from Dante, Ravenna, and other audio over IP solutions that use these protocols. SDP (Session Description Protocol) information can also be manually inserted for interoperability with third-party solutions that do not support these standards. Powered by Barix’s Linux-based IPAM 400 audio module, the Exstreamer M400 features higher processing power than earlier Exstreamer models and a more programmable, software-driven architecture that enables easier expansion, rapid prototyping, and greater customisation. A larger buffer size and advanced buffer management technology can be configured

to further bolster the Exstreamer M400’s resilience to network performance disruptions in applications where minimising latency is not critical. Expanded support for IT security standards includes HTTPS: support for audio streams and the web-based management interface, plus secure, encrypted SIP communication links using TLS and SRTP. Other new features relative to earlier Exstreamer models include IPV6 support and internal audio file storage with externally triggered playback. The Exstreamer M400’s Linux-based architecture enables extensive upgradability. A modern API is planned for future release for developers, replacing previous Exstreamer models’ older CGI control specification. Visit
