NETWORK AUDIO ADAPTER
NX-100S
DESCRIPTION
FEATURES
The NX-100S Network Audio Adapter will perform real time
transmission of high quality audio signals as well as control
data over IP networks such as LANs and the internet.
Particularly effective for transmitting audio to remote locations
as the ability to use the internet instead of dedicated lines
reduces operational costs. The NX-100S can also be fitted
with an optional rack-mounting bracket to allow it to be
mounted in an industry standard (1 unit size) EIA rack.
● Wide-ranging audio bandwidth from 50 Hz up to 14 kHz
with high fidelity sound and perfect clarity.
APPEARANCE AND DIMENSIONAL DIAGRAM
Rear View
● Without network delay, audio signals only have a minimal
delay of milliseconds.
● Efficient sub-band ADPCM audio compression technology
retains delicate musical instrument nuances as well as the
emotional content of a person's speech.
● Higher audio performance achieved when using
uncompress (PCM) audio transmission. Selectable
sampling frequency transmission rates of 8kHz, 16kHz, or
32kHz to best match the transmission frequency range.
● NAT and IP Masquerade (IPMASQ or MASQ) networking is
supported with cost savings for installation and operation
compared to using dedicated lines.
● The NX-100S employs three modes to recover lost packets.
● Supplied setup software or web browser can be used for
setup, adjusting settings and maintenance for a network.
Firmware updates can also be performed.

● The NX-100S also adjusts sampling frequencies both at the
sending and receiving ends so that uninterrupted
continuous broadcasting may be possible for long hours
even if communication interference should occur on
networks.
● Two-way audio signal transmission is possible even with
two NX-100S units as every unit is equipped with an audio
input and output.
Side View
● The multicast-capable NX-100S allows simultaneous
transmission of audio signals to be made to multiple
locations depending on transmission method:
Unicast: up to 4 locations,
Multicast: up to 64 locations.

● The NX-100S's contact input can initiate and terminate
audio transmissions without dedicated control equipment
such as a PC.
Unit: mm
● Hardware use ensures operational reliability over just
software-driven applications.
● The NX-100S is equipped with an indicator for audio signal
in as well as a peak overload indicator, allowing at-a-glance
visual confirmation of status when making settings.
● The NX-100S provides phantom power on audio inputs.

Note 2: Voice Packet Loss Recovery
Voice Packet Loss Recovery is a processing method when
a voice packet cannot be received due to communication
interference.
Silence: Method of processing lost sectors as silence.
Redundancy: Method of accurately outputting continuous
losses of up to 8 packets.
Resend: Method of accurately outputting continuous
losses of up to 15 seconds.
Note 3: Required band
Required band represents the frequency band required for
voice transmission. When it is necessary to transmit serial
data, a transmission band is separately required.
