The nWall
The MediaMatrix nWall is a surface mount CobraNet interface panel with two analog
microphone/line level input channels. The device converts audio from the input channels to a
CobraNet audio stream. It can then be routed via CobraNet bundle transmitters over a local
area switched network using CAT5e UTP cable.
The nWall eliminates the need for long runs of analog microphone cables terminated in racks
of patch bays as typically seen in ballrooms and convention centers. As the connection to the
nWall uses CAT5e UTP cable with network standard RJ-45 crimp connectors, the installation
time, number of terminations required and associated cost are all minimized.
The nWall can be used in numerous places such as hotels, bars and restaurants, schools and
many other venues.
Notes
:
If you want to control and monitor an nWall using an NWare project, you will need an
nControl unit or nTouch 180 unit. If you simply want to transmit audio from an nWall onto
the CobraNet network these devices are not required. However, before any connection can
be made you must configure the nWall with an IP address by Using
CobraNet Discovery
(on page 19) or by using
NWare
(on page 20).
The nWall can only be powered via an IEEE 802.3af PoE compliant network switch. This
must provide up to 15.4W of DC power (minimum 44V DC and 350mA) from each
individual port over CAT5e UTP cable.
Features
Two unbalanced TRS 1/8” (3.5mm) mini jack inputs - summed mono for PC and Aux
consumer line level audio products support off the shelf consumer audio cables.
Balanced XLR inputs - mic/line selectable gain via front panel 3 step rotary switch allows
quick source setup at the wall panel. XLR connector is latchless to minimize mechanical
damage to the interface panel.
Digital patching - using MediaMatrix NWare any number of nWall panels can be patched
to any number of NION processors on the fly, eliminating the need for expensive patch
panels and greatly reducing setup time between events.
Analog to digital conversion at the wall panel reduces problems with buzz, hum, ground
loops and other cable issues, also eliminating the need for isolation and impedance
matching interfaces.
Structured cabling to greatly reduce critical path delivery time and costs.
Power over Ethernet (PoE).
Low power requirements.2-gang NEMA mount.
CobraNet audio transport via switched network and RJ-45.
Easy wiring and installation.
Cost effective.
