TTOOAANNXX--110000SS
The TOA NX-100S network audio
adapter was awarded “Best Audio
Routing Product For Commercial In-
stallation” at the AV Communica-
tions Excellence Awards Banquet
held June 7, 2005 at InfoComm 2005
in Las Vegas.
“We’re extremely pleased and ap-
preciative to be recognized by the
industry with this award,” said
Steve Mate, Sr. marketing manager
at TOA Electronics, Inc. “With over
two years of successful installa-
tions, the NX-100 technology has
proven to be a solid, reliable solu-
tion for distributing audio over IP
networks.”
PRODUCT OVERVIEW
TOA NX-100 series network audio is
a reliable and easy to use method
for transporting mic or line-level au-
dio signals over IP-based local and
wide area networks (LAN/WAN), as
well as the internet. Applications in-
clude wide area paging, background
music or messaging audio distribu-
tion for airports, corporate campus-
es, convention centers, railway sta-
tions and transit systems.
The flagship model NX-100 trans-
ports variable bandwidth, bi-direc-
tional audio, up to 14 kHz, as well as
serial RS-232 and contact closure
data. Each half-rack sized unit in-
cludes a balanced mic/line input
and output and a 10/100BaseT Eth-
ernet jack for connection to stan-
dard network hardware. The rear
panel includes eight programmable
trigger inputs to initiate and termi-
nate audio transmissions, eight pro-
grammable open collector control
outputs and an RS-232 serial port
for data transmission/reception.
The NX-100 also has a built-in
web server to support browser-
based programming, control and
monitoring from any network-con-
nected PC. Other features include
multiple error correction modes, ex-
ternal 24 VDC input, and Flash-up-
gradeable firmware.
The new streamlined and cost-ef-
fective NX-100S includes all of the
same features as the NX-100 minus
the RS-232 transport and external
24 VDC capability. Enhancements
include front panel signal and peak
LED’s plus phantom power for con-
denser microphones.
Both the NX-100 and NX-100S are
backed with a five year warranty.
FEATURES
The NX-100 Series Network Audio
converts a mic or line level analog
audio signal to digital packets for
transport over IP-based networks to
other network-connected NX-100’s
for conversion back to analog. The
NX-100 significantly reduces instal-
lation and operational costs when
distributing audio signals to multi-
ple remote locations by allowing
the use of existing data networks
(LAN, WAN and the internet).
The NX-100 can simultaneously
send and receive audio to/from sin-
gle or multiple NX-100’s at remote
locations. In addition to the audio
stream, the NX-100 can simultane-
ously transport RS-232 serial data
and contact closures for remote
control of peripheral equipment.
Transmission Method
Each NX-100 has a fixed MAC ad-
dress and requires a static IP ad-
dress. Each NX-100 communicates
with single or multiple NX-100’s in
Unicast or Multicast modes. In Uni-
cast mode, the NX-100 can send up
to four identical streams to up to
four NX-100’s over LAN, WAN or the
internet. In Multicast mode, the NX-
100 can send a single stream to up
to sixty-four NX-100’s within a multi-
cast-capable LAN or WAN.
Front and Rear Panel Features
The NX-100 front panel includes
Link/Activity, Full-Duplex/Collision,
Status, Error and Run LED indica-
tors plus a recessed hardware Reset
button. The NX-100 rear panel in-
cludes a balanced mic/line input
with adjustable volume control and
a balanced line output. A standard
Ethernet port (10/100BaseT) allows
connection to Ethernet-based net-
work hubs or switches. An RS-232
serial port is configurable as a TCP
client/server or for UDP data trans-
port with adjustable baud rate up
to 115200 bps. Eight programmable
contact inputs can be used to trig-
ger Broadcast Patterns (described
below) as well as activate single or
multiple contact outputs on remote
NX-100s. The NX-100 is powered
with the AD-246 AC adapter or ex-
ternal 24 VDC power supply. Alter-
native versions of the AD-246 are
available for worldwide use.
Sampling Rates And Audio Quality
The NX-100 provides three audio
quality modes: 50 Hz to 14 kHz (32
kHz sampling), 50 Hz to 8 kHz (16
kHz sampling) and 50 Hz to 4 kHz (8
kHz sampling)—analogous to FM ra-
dio, AM radio and telephone quality
respectively. The network band-
width for each mode depends on
packet size, compression on/off and
packet loss recovery settings.
Delay Time
The delay time (latency) of a
point-to-point NX-100 transmission
depends on several factors includ-
ing sampling frequency (audio qual-
ity), packet size, compression and
packet loss recovery settings. The
minimum delay possible is 20 mil-
liseconds. Because of this, the NX-
100 is not intended for use in live
sound or similar applications but is
instead well-suited for paging, mes-
saging or background music distri-
bution over existing data networks.
Broadcast Patterns
You can store up to 20 broadcast
patterns or “audio distribution pre-
sets” in each NX-100. A broadcast
pattern can be configured to trans-
mit audio to single or multiple units
or to receive audio from a specific
unit. Patterns can be activated us-
ing the eight contact inputs, or with
the included operation software as
described below.
Contact Inputs And Outputs
Eight contact inputs are assignable
to activate broadcast patterns
and/or contact outputs on other
units. The eight contact outputs are
open collector type with adjustable
contact off delay time from 0 to 60
sec. Each contact input and output
is individually configurable as mo-
mentary/latch and normally
open/closed. Each contact output
can also be configured to activate
to indicate an error condition.
Built-In Web Server And Browser
Programming
Each NX-100 has a built-in web
server allowing configuration and
monitoring via common web
browsers.
Transmission Data Format
The NX-100’s audio stream uses
the User Datagram Protocol (UDP).
The serial RS-232 and contact closure
data are transported using the Trans-
mission Control Protocol (TCP).

ment, manufacturing and distribution
