Facilitating real time audio tr

The top-rated NX-100 and affordable NX-100S Network Audio Adapters share
many common features and functions related to transmitting high quality
audio signals over IP networks such as LANs and the internet in real time.

NX-10 0S

Real time transmission of high quality audio signals over
IP networks.

Audio can simply be transmitted as IP packets via a router or an
intelligent switch. Without any network delay, the audio broadcasts
will only experience delay times as minimal as tens of milliseconds.

Audio signal quality maintains high fidelity over a wide
frequency range from 50 Hz up to 14 kHz

The NX-100/NX-100S incorporates efficient ‘‘sub-band ADPCM’’
audio compression technology that preserves delicate musical
instrument nuances and allows the emotional content of a
person's speech to be transmitted as well. Malfunctions and
emergency signals and other sounds can also be accurately
monitored and evaluated thanks to the high level of fidelity. If a
higher level of audio performance is required, the NX-100 will
also uncompress (PCM) audio transmission. Sampling frequency
transmission rates can be selected at 8kHz, 16kHz, or 32kHz to
best suit the transmission frequency range.

Multi transmission modes available — LANs and dedicated
lines as well as transmitting audio over the internet.

The NX-100/NX-100S supports NAT and IP Masquerade
(IPMASQ or MASQ) networking which present technological
difficulties to conventional VoIP (Voice over IP) technology and
protocols such as H.323 and SIP. These advanced abilities of the
NX-100/NX-100S result in dramatic cost savings for both
installation and operational costs.

Note: Connected to the internet, the private IP address is converted into a global IP
address by the router. NAT and IP Masquerade perform this address conversion.

Equipped with the Voice Packet Loss Recovery and
sampling frequency adjustment functions

The NX-100/NX100S employs three modes that are employed to
recover lost packets. Both also adjust sampling frequencies at the
sending and receiving ends so that uninterrupted continuous
broadcasting may be possible for long hours even if
communication interference should occur on the network.

Simultaneous multi-location broadcasting and two-way
communication capabilities widen scope of applications.

A single NX-100/NX-100S unit can simultaneously transmit audio
signals to a maximum of 4 locations in the Unicast mode and to
up to 64 locations in the Multicast mode. This makes it possible to
effectively perform company-wide broadcasting and also to
integrate broadcast diffusion functions.
Every NX-100/NX-100S is equipped with independent audio input
and output connectors that can be operating simultaneously,
allowing use as a broadcast monitor or as a communication
device responding to the location receiving the broadcast.

NX-10 0

8 channels of contact inputs/outputs are provided. The
RS-232C port on the NX-100 can be used to send serial data
to and from remote areas.

Control input signals as well as audio signals can easily be
transmitted to remote locations. The signals can be employed for
power on/off control of the PA amplifier which receives the voice
output. In addition, other useful tasks include broadcasting start
using the sensor or timer, activating an external music source
and selecting the broadcasting area for each of the input
terminals.

Software-driven operation or through input terminals.

Multiple NX-100/NX-100S units can be operated via an IP
network employing the supplied operation software and
broadcasting can also be initiated and terminated using the input
terminals for the maximum operational reliability of a hardware
solution. A full system can be assembled without including a
single PC.

Simplified setup and maintenance using supplied setup
software or web browser.

Supplied setup software makes it easy to perform routine tasks
such as changing settings, checking operational status, and
updating firmware for all NX-100/NX-100S units on a network.
The NX-100/X-100S is an exceptionally low maintenance
product, even allowing any PC without setup software
installed to complete tasks via web browser for individual
NX-100/NX-100S units.

NX-100S dedicated features.

The NX-100S is equipped with an indicator for audio input signal
as well as a peak overload indicator, allowing at-a-glance visual
confirmation of status. In addition, the NX-100S also provides
phantom power on the audio inputs.

Differences between the NX-100 and the NX-100S

NX-100 NX-100S

Power source Input
RS-232C port Yes No
Input signal LED No Yes
Input peak level LED
Phantom power supply
IPv6-compatible Yes No

The NX-100 is the first audio equipment to sport the
IPv6 Ready logo. Dedicated firmware update must be
installed on the NX-100 to make it fully IPv6-compatible.
