MediaMatrix Simplifies Digital Audio Transport With New nWall Series Interface Panels

June 13, 2012

Peavey® Commercial Audio proudly introduces thenew MediaMatrix® nWall™ 1.1, a surface-mount input/output panel, and the nWall 0.2, a surface-mount audio output panel.

The nWall 1.1 and nWall 0.2 offer high-quality analog-to-digital and digital-to-analog audio conversion and CobraNet transport for MediaMatrix, the most flexible and capable audio networking system and the pioneer of computer-based audio processing and control interfacing systems. Designed with the consultant and contractor in mind, nWall Series interfaces offer flexible remote configuration and deployment options to provide an efficient and elegant solution for any number of applications.

“The nWall Series is an extension of the growing line of MediaMatrix products designed to put entire solutions at the fingertips of the designer and contractor,” said Hartley Peavey, founder and CEO of Peavey Electronics Corporation. “MediaMatrix continues to expand to include an entire range of control products, all designed to allow the integrator to design, create and deploy complete systems without the additional expense, programming and complexity of third-party control systems.”

The nWall 1.1 features an XLR connector that can be configured for multiple audio input sensitivities from -56, -26 to +4dBu, selectable via rotary switch on the unit’s front panel. The XLR input supports electret condenser and dynamic microphones plus line-level audio with 15V DC phantom power. In addition, a 1/8”(3.5mm) TRS mini jack accepts a nominal -8dBU signal that is summed to mono and mixed with the XLR input.

By converting a balanced XLR input and a 1/8” input into a digital audio stream at the panel, the nWall 1.1 greatly reduces buzz, hum, ground loops and other cable issues, eliminates the need for isolation and impedance matching interfaces, and replaces long analog cable runs with a single CAT5e UTP cable.

The nWall 1.1 also provides one line-level output, via a balanced XLR connector or a 1/8” TRS mini jack output.  The line output level can be adjusted with a three-position rotary switch on the face of the nWall 1.1 panel. 

The nWall 0.2 features two balanced analog outputs converted from a single CobraNet network connection. The nWall 0.2 provides one XLR connector and one 1/8” TRS mini jack connector for each output.  The level of each output may be adjusted with a three-position rotary switch associated with each output on the face of nWall 0.2 panel.

MediaMatrix nWall Series interface panels fit in a standard two-gang NEMA back box, and are powered over the attached network cable from a network PoE-capable network switch that conforms to IEEE 802.3af.

Any number of nWall panels can be patched to any number of MediaMatrix NION®processing nodes on the fly, eliminating the need for expensive patch panels and greatly reducing setup time between events.

  • CobraNet audio transport via switched network and RJ45
  • Crimp connectors greatly reduce critical path delivery time and costs, replacing the need for skilled labor to solder/terminate typical analog interface panels
  • Electronic 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.
