Description of NAP500 (500W,3U) IP/TCP Network Audio System IP-NAS software Series

ThelP PA amplifier range is an ideal network audio solution for multiple speakersmiddle

sizedapplications. It is used to transmit program from internet to its built-inamplifier then

to100V,70V or low impedance loudspeakers. So the normal connection way as below:

Controlport by RJ45 connector to LAN switch and speaker outputs to loudspeakers.

ThelP network audio adopter is of 19 rack mount design, it is built-in a poweramplifier

outputrated at 60W, 120W, 240W to 500W. This LAN network technology also allow this

lPnetwork audio adopter with amplifier could be installed anywhere of the LANsystem,

thusthe cable wiring cost could be saved.

Thebiggest advantages of the network audio system are: Super distance audiotransmission,

simultaneousmaximum program task and non-dedicated network wiring.

Multipleloudspeakers could be directly powered by the built-in power amplifier.

It isalso designed of local end-user program selection from server by remotecontrol. Local

volumealso could be adjusted by remote control. Remote control is also could be usedto

writeand change the lP address. Password is needed to access control the equipment’sto

avoidunintentional error.

Thenetwork audio adopter also is designed with a local microphone input and alocal line

input,a volume control could be used to adjust the speaker loudness. Three wiredvolume

controlis also optional to be connected to this unit. Two reserved communication portsby

RJ45type for future upgrade. One serial communication port only shall be used towrite

in orchange the IP address.

Automaticenter standby mode if no input is detected for 5 minutes and automatically

backinto service once input is detailed.

Twolevels of priority output: Voice evacuation system with highest priority andlocal

inputwith secondary priority over program source. However, the local input andprogram

sourcepriority could be customized.

Indicatorsinclude output level meter, amplifier power indicator, protection indicator and

equipmentpower indicator.

Hightemp, overload and short circuit amplifier protection
