Audio Network In Wall Interface Panel
The audio network interface panel shall be an in wall surface mount panel housed within a NEMA 2-gang back box designed for fixed installation in engineered
audio and communication systems. It shall provide up to 4 input analog audio channels supporting both microphone and line level balanced and unbalanced line
audio sources with input attenuation being selectable from rotary switches located on the front panel. The balanced analog audio inputs shall provide for 15V
DC phantom powering for microphones. The audio network interface shall be powered from Power-over-Ethernet according to standard IEEE802.3af. The
audio interface panel shall be a 2 channel device, where internal circuitry shall mix and sum mono the TRS mini jack and XLR inputs for each channel allowing
for the audio inputs to be transmitted over an audio network. The audio network shall be CobraNet™, operating on a 100Base-T Ethernet physical interface.
The network interface panel Ethernet port shall be side mounted to ensure connected network cable has sufficient bend radius. Remote set up and control
via Ethernet shall be possible for CobraNet settings. A software device to control the audio network interface panel shall be available for integration into the
NWare configuration file. The audio network interface panel shall be the MediaMatrix nWall or approved equal.
Front Panel Connections
2 x balanced XLR3 (F) inputs (latchless).
Rotary (3 step) switch supports each adjacent
XLR. Selectable gain attenuation: -56dBu / -26dBu
/ +4dBu (nominal) with +20dBu (peak) headroom
for each setting.
2 x unbalanced TRS (F) 1/8th inch mini jack inputs
summed to mono then mixed with XLR, -8dBu
(nominal) +12 dBu (peak).
2 x blank label boxes for custom labeling of each
input channel.
Rear Panel Connections
LAN: RJ-45 socket for CobraNet and control
communications on 100Base-T Ethernet. Requires
Power-over-Ethernet (PoE) via an IEEE 802.3af
capable network switch.

(Allocated to XLR inputs)
CobraNet Performance
2 audio sub channels at 48 kHz sample rate,
5.33ms latency to CobraNet transmit bundles.
System Configuration
Audio interface panel IP settings, CobraNet bundle
settings and sub channel mapping assignments
remotely accessible via Ethernet network
from within MediaMatrix NWare software and
CobraNet Discovery Utility software.
Power / Data requirements & connection
Requires IEEE 802.3af PoE compliant network
switch that provides up to 15.4 W of DC power
(minimum 44V DC and 350 mA) from each
individual port over CAT5e UTP cable.
Power over Ethernet (PoE):
Consumption = 350 mA (Max)
Mechanical Specification
Dimensions: 4.57" (116mm) W x 2.0" (51mm) D
x 4.5" (114mm) H
Net Weight: 1.54 lb. (0.70 kg)
Mounting: NEMA 2-gang finish plate, requires
2.25" clearance depth minimum. Mount in metal
box coupled to EMT conduit.
NOTE: Take care to ensure that back box
and conduit coupling hardware, wire or other
terminating devices do not obstruct the installation
of the nWall circuit assembly.
Finish
Grey powder coat on 18 gauge CRS.
