FAULT DETECTION

X-DA4125EN can self-protect from overheat, over current, over voltage

and under voltage. For example, when the internal temperature reaches

its critical limit, the overheat protection circuit will shut down the power

amplification module and activate the protection indicator light on the

front panel.

X-DA4125EN can detect power supply errors automatically during operation.

The built-in fuse will provide over current protection to the main power supply.

When a shout circuit is detected in the main power supply circuit, the power

will be automatically shut down.The backup power supply will then be enabled

to replace the main one.

When a fault, self-protection or self-testing happens, its audio input fault por

on the rear panel will short circuit and a fault signal will then be sent to the

control unit in the network.

SAFETY

The device adopts lightweight design. The front panel is made of UL94V-0 fire

proof ABS material, protecting the machine under extreme conditions.

A cooling fan is equipped for heat exhaustion so that the machine can maintain

high working efficiency. The amplifier can work without main power in emergency.

VOLUME CONTROL

When HN-D32N Noise Detector is installed, X-DA4125EN can adjust volume

according to the ambient noise automatically to ensure high sound intelligibility.

required applications.

Features

INPUT/OUTPUT

X-DA4125EN supports both balanced and unbalanced audio inputs.

To receive unbalanced audio inputs, simply connect the ground port

with the negative input port to the rear panel. X-DA4125EN can receive

audio signal from XDCS2000/EN via Ethernet through the RJ45 standard

port.

X-ND100 (Digital Noise Detector) is used to detect ambient noise,

automatically calculate the noise SPL, and transmit the SPL data to

X-DCS3000. It is an important component tofulfill the function of automatic

volume control. While broadcasting, the sound is mixed with ambient noise.

In order to measure the noise SPL accurately, X-ND100 measures

broadcast signal from speaker lines, comparing with the signal from

microphone to get the actual noise data.

FEATURES AND BENEFITS

• Connect toX-DCS3000 by a pair of cables, through which fulfill

communication and power supply.

• Max. 5 noise detectors for each channel.

• Max. transmission distance is 1000m.

• Flush-mounting in ceiling.

• Currently collect broadcast signal and noise signal.

• Fire-proof ABS shell.

• Ideal for indoor installation.

Functions

The function of the keys on X-K8 can be configured as:

• Zone selection. Each zone represents one speaker line.

• Group selection. Each group represents multiple speaker lines.

• Broadcast task selection. The operation mode of the keys can be configured

press or toggle.

• Volume control

• Zone Close

For different key functions, the LED indicators display differently. When

the key is configured as zone/group selection, the LEDs can indicate the

selection status, fault and working status. When the key is configured as

broadcast task, the LEDs can indicate the broadcast status of the task.

FEATURES & BENEFITS

• Power supply from X-NPMS or X-NPMK

• Eight configurable keys

• A two-color LED indicator for each key

• Flexible label slot with changeable labels

• Each X-NPMS or X-NPMK can connect up to 8 extension keypads

• Support rack mount or desktop flush mount

• CE & CB Complied

TOUCH SCREEN

Users  can operate directly on the innovative  7-inch

color LCD touch screen without adding an extra key

module unit.With the touch screen, users can super-

vise  the  system  status,   select  broadcast   zones,

assign  zone  groups  or  other  broadcast   controls,

including setting playlists,  timing broadcastings  etc.

With   the   built-in   configuration   software,   zones

broadcast status or button functions can be configu-

red easily.

CONNECTIONS

X-618  system  can  connect with up to 250 X-NPMS

via  Ethernet.  X-NPMS   can  be   used   as  a  node

anywhere in the network. To  reduce wiring cost,  the

devices can be connected  into an  existing  network

provided that there is sufficient band width to reduce

wiring cost.

AUDIO TRANSMISSION

The  device  comes  with  a  detachable  gooseneck

microphone.  Users  can  change  different  types of

microphone   for   different   real-time   broadcasting

requirements.  The  received  audio  signal   will  be

digitalized to eliminate sound distortion during trans-

mission.

The built-in speaker  not only  can be  used for zone

monitoring but also full-duplex intercom with other X

NPMS in the network.

X-NPMS  supports  fail-safe  operation.  Even  when

the  connected  DCS  fails,  X-NPMS  is  still  able to

communicate  with  other  X-NPMS  and   broadcast

through other DCS  in th network.

INDICATORS

POWER indicator:  Show  power supply status,

green means normal .

RUNNING indicator: Show devices working

status, flashing green means normal.

FAULT indicator: Show faults of system.

If  there  is  a  fault, the  indicator will be  flashing

yellow. And when the fault  is confirmed, it  keeps

lighting yellow.

The  indicator  will  be  off  when  the  system  is

normal.

NETWORK  indicator:   Show  network status.

Yellow   means   network   connection  failure.

Flashing   yellow   means  network  has   been

connected  but the station  can’t communicate

with other device.

Green  means  normal.

MIC  WORKING  STATUS  indicator: show  the

working  status of microphone.

Yellow  means  a  fault  of  microphone.

Flashing   green  means  broadcasting  warning

tone.

Green  means  microphone  is   working.

The indicator is off  when  microphone is normal

and not  working.

• Easy  touch  screen  operation  with 7’’  TFT  LCD  screen

and  simple  user  interface.

• Optional  gooseneck  microphone  or  PTT  microphone.

• Built-in  loudspeaker  for  audio  monitoring  and  inter

communication  function.

• Configurable  keys  for  audio  task  delivery,  zoning  and

grouping.

The X-NPMS connects to the X-618 system, transmitting audio

and  control  signal  through the Ethernet.  It  is used  for  live

paging, audio task delivery ,  audio  monitoring  zones ,  and

intercommunication.
