ACCESS NX Portable
Since ACCESS was introduced over a decade ago, it has become the world’s leading IP audio codec and in that time, IP transmission technology has developed significantly. Comrex has taken its our world-class platform, along with the last decade of technical growth and built a brand new platform for the future – ACCESS NX. ACCESS-NX is the latest incarnation of the industry-standard ACCESS-IP from Comrex and provides a step-change in stability and resilience in IP audio codecs. Equipped with a 5-inch capacitive touch screen and improved user interface, ACCESS-NX is simple to operate in the field. It has 2x Mic/Line switchable inputs plus a stereo tape input plus there is an optional add-on 4-channel mixer making 6x users in all.
IP infrastructure is growing rapidly, and networks are available virtually everywhere. ACCESS NX offers several ways to get connected. Developed from the ground up for use over the public internet, with 2-way, stable, stereo, low-delay audio over pretty much any type of internet connection including wireless systems such as WiFi, 4G and 3G. For those who need to use public Wi-Fi, ACCESS NX can log in to IP networks through the integrated web browser. This allows users to type credentials into login screens and agree to usage terms, which expands networking options. Still need to use POTS? ACCESS NX is compatible with a USB POTS/PSTN modem for use on legacy analog phone lines - USB modem sold separately
ACCESS-NX uses the latest generation of digital processing to provide multi-streaming high-quality stereo audio using CrossLock that creates a Virtual Private Network (VPN) between codec devices. This VPN can have its own rules about when to resend packets and it can do it in a much smarter way by building extra data streams between the codecs that relay important information (e.g. decoder statistics back to the encoder).
Comrex Switchboard Traversal Server was created to make it easy to make connections between Comrex IP codecs. This is especially important when broadcasting over networks that have firewalls and routers and other IT snags. Switchboard allows your codec to sync with a cloudbased server, making it possible to connect without having to know the IP addresses on either end of the link. Switchboard saves all the details of the codecs subscribed to the server. This means that when it’s time to connect, you don’t have to enter any information – you can simply choose the codec you want to connect to from a menu, and hit a button.
Studio Counterpart Codecs
ACCESS-R is the industry standard IP Audio Studio Codec with wide compatibility including N/ACIP SIP-EBU-3326 compliance. It is a platform for CrossLock which is the “reliability layer” that makes it all work and provides balanced stereo analogue and AES-EBU digital audio in-and-out.
ACCESS-NX Rack has the same capabilities as the ACCESS-R and features a new, user-friendly, web-based interface. It also provides AES67 in addition to AES3 and analogue audio.
ACCESS MultiRack has five full-duplex ACCESS audio codecs in a single rack unit. Perfect for large operations, ACCESS-MultiRack allows simultaneous connections to ACCESS Portables (Classic, 2USB and NX), ACCESS Racks (Classic and NX), BRIC-Link (Classic and -II) and software codes including CallMe and FieldTap.
BricLink-II is a cut-down version of the ACCESS, still providing all the clever forward error correction and error masking, multi-streaming and CrossLock. It does not have the full list of coding algorithms but includes G.772 and Opus. Two BricLinks can be mounted side-by-side in 1-U.
While the ACCESS-NX has been optimized to provide complete mobility and solid reliability, the ACCESS Rack has been designed as its perfect studio counterpart. The ACCESS-R rackmount is a 1U unit with analogue stereo audio inputs and outputs plus digital AES on XLRs. There are also serial and GPI ports which can be sent alongside the audio to the connected unit. A standard phone line connection and Contact Closure completes the rear panel. ACCESS Rack can be directly controlled with a keyboard or mouse, a USB touch screen monitor, or driven with a standard web browser. The front panel shows only send and receive audio levels plus network status whilst all setup and connection functions, as well as detailed status, audio levels and network statistics are accessed through the user-friendly web interface. Operation is as simple as selecting a remote unit from the ‘address book’ and clicking Connect, while advanced configuration menus are available for power users who wish to configure all aspects of the audio coding process.
