Brochure

Since it was released in 2005, the Comrex ACCESS Rackmount has
become an industry standard. Now, it’s been updated to incorporate
the latest technological advances.
ACCESS NX Rack features completely redesigned hardware, allowing
for AES67, AES3 or analog audio I/O. NX Rack can connect to Wi-Fi
and 4G modems, and supports a wide range of connection protocols
and audio encoders. It’s driven via a new HTML5-based web user
interface. ACCESS NX Rack is backward-compatible with all Comrex
IP audio codecs and the Comrex FieldTap smartphone app.
Applications
ACCESS NX Rack is the perfect
studio counterpart to ACCESS
remote codecs. With robust encoding
algorithms and CrossLock, the most
sophisticated network management
technology on the market, ACCESS
NX Rack provides solid and reliable
connections over Ethernet, Wi-Fi,
and 3G/4G networks.
ACCESS NX Rack is also a reliable
point-to-point IP audio codec. For
connecting from studio to studio,
or maintaining a 24/7 connection,
ACCESS NX Rack provides a
reliable connection for long-term
broadcasts.
Switchboard
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 cloud-
based 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.
CrossLock
Quite simply the most advanced
network management tool on
the market today. When used in
“bonding” mode, CrossLock gives
users the ability to manage and
bond multiple data connections
together simultaneously. When
a new network is introduced,
CrossLock will immediately evaluate
how much bandwidth is available,
while factoring in latency and jitter
information, and combine the two
connections to take advantage of all
available bandwidth. In Redundant
mode, all data will be sent over
all networks. CrossLock can also
monitor each data connection
individually and, when necessary,
apply appropriate error correction,
recovery, or concealment
techniques.
