KLARK TEKNIK Announces New DN9620 AES50 Extender

DN9620 AES50 Extender (PresseBox) (UK, ) Building on the success of the company's highly acclaimed DN9650 and DN9652 network bridges and DN9610 AES50 repeater, KLARK TEKNIK has added the new DN9620 AES50 Extender to its product portfolio.

A 1U, half-rack width AES50 extender, the DN9620 accepts two CAT5 AES50 streams, multiplexing up to 96 bi-directional channels of 24-bit audio via a single fibre-optic cable (up to 500 m), or a single CAT5E cable (up to 100 m). With its astonishingly low input-to-output latency at a mere 0.105 ms, the DN9620 can be operated at 96 kHz or 48 kHz sample rates and provides multiple clocking options. Utmost reliability is ensured thanks an integrated auto-ranging power supply and genuine Neutrik EtherCon and OpticalCon connectors.

The DN9620 overcomes the inherent limitations of CAT5 cabling, which limit cable runs between AES50 devices to 100 metres (330 feet). MIDAS and KLARK TEKNIK Brand Development Manager Richard Ferriday explains: "The DN9620 serves many functions. It will operate as an optical snake system for any MIDAS, or other digital console which uses the AES50 protocol, it will provide long-haul, optical connectivity between I/O boxes, as well as extending the deployment possibilities of I/O, recording, and other AES50 hardware throughout a building, or campus".

AES50 is an open-architecture digital audio transport protocol which benefits from extremely low latency (<70us.), robust feed-forward error connection and advanced system clocking. AES50 connections carry digital audio and control data bi-directionally, down a single CAT5e cable. The benefits of combining audio, control, and clock into one single network are simplified connectivity, reduced set-up times, and lower investment in cabling infrastructure.

The KLARK TEKNIK DN9620 will be shipped in pairs, complete with a dedicated 19" rack mounting bracket.

MIDAS builds live performance mixing consoles that have been used by the world's most demanding sound engineers, performers and rental companies since 1970. The company is dedicated to raising the standards of sonic quality through its programme of continual research and development and stringent manufacturing processes. MIDAS engineers are also focused on implementing new control functionality and user-friendly desk operation to anticipate and accommodate the ever-evolving needs of audio professionals who specify MIDAS consoles for their major tours, festivals, international events, broadcast projects and prestigious fixed installations.

KLARK TEKNIK was founded in 1971 and in the years immediately following, their innovative approach to design and development allowed them to introduce some truly groundbreaking designs. KLARK TEKNIK was responsible for one of the world's first digital delay and digital reverb units; however it was their concepts for equalisation devices that really changed the world of professional audio resulting in the DN370 and the famous DN360. Today KLARK TEKNIK continues to bring innovation in design and dedication to engineering and sonic quality in both the analogue and digital realm of signal processing.

MIDAS and KLARK TEKNIK are owned by MUSIC Group.
