KNTECH IP Based PAGA System and PA System

Main PA Server for PA System

1. A/B system Main server can choose active/standby hot backup.
2. A/B active / standby IP amplifier hot backup.
3. The speaker cable is connected to the spare power amplifier. The main power amplifier works normally. When the main amplifier fails, it will automatically switch to the backup amplifier.
4. All amplifiers are IP amplifiers, can play different audio sources at the same time.
5. The Console and the main / backup IP amplifiers are automatically connected to the A/B main server, and when the A server fails, it will automatically switch to B server.
6. PA linkage box can be customized to connect with third-party systems through RJ45/dry contact, audio source/RS485 Modbus RTU/ModbusTCP//RS232 and other protocols to linkage broadcasting function.
7. The beacon control box supports that when the broadcast is started, the beacon turned on, and when the broadcast is ended, the beason are turned off automatically.
8. A single smart speaker uses the original audio cable for self-detection and report the speaker state to console.
9. The speaker line loop automatically detects and reports failures. Even if the speaker line is cut, the remaining speakers can continue to work normally.

KNTECH PA System

PA Ssystem A+B Model

1. A/B system host active backup hot backup.
2. A/B active and standby power amplifier hot backup.
3. The speaker cable is connected to the spare power amplifier. The main power amplifier works normally.
When the main power amplifier fails, it will automatically switch to the backup power amplifier.
4. All power amplifiers are IP power amplifiers.
5. The dispatcher and the main and backup IP power amplifiers are automatically connected to the A/B host, and
when the A host fails, it will automatically switch to the B host.
6. The warning light control box supports that when the broadcast is started, the warning lights are turned on, and
when the broadcast is ended, the warning lights are turned off.
7. A single smart speaker uses the original audio circuit to perform fault self-detection and report actively.
8. Speaker circuit loop detectio

KNTECH Amplifier with A/B Redundant Line

Customers can decide whether each amplifier needs to be equipped with A/B redundant 100V output according to the project budget.

Speaker Line Detection

Check whether the line is working properly by monitoring the speaker line.

The Software of PA console to update the health status of the horn line in real time.

If the wire is broken anywhere in the middle, other speakers still work normally without any influence.

Singal Speaker Healty Status Detection

Unable to into tunnel?Hard to find which speaker fail?

Too high to reach speaker?Hard to find which speaker fail?

KNTECH PA system just siting in the office and monitor all speaker health status.

Customers can choose the version of IP amplifier with speaker health check module,
Conventional two-core speaker cable, no need to add lines.
The PA console can monitor the health status of each single speaker in real time.

Singal Speaker Healty Status Detection

1. Amplifier send detect signal to each speaker

2. Speaker feed back detect signal to amplfier

3. Amplfier send detect siganl to PA server

4. PA server send detect result to console to display

Interface with the Third-party Model

Use various ways to connect with third-party systems

Realize the automatic linkage broadcast of fire control system, broadcasting system and telephone broadcasting system

Protocol automatic linkage method:

Dry contact/3.5mm audio interface ModbusTCP/ModbusTCPRS485/Modbusrturs232

Analog audio mode

dry contact method

Interfacing with Telephone System

Interfacing with the telephone system through the telephone interface software of KNPA08-TEL

Extreme cases in which-reliability

1. Standby power amplifier power output power of any main power amplifier machine.

2. The standby power amplifier machine can replace any one of the main power amplifier machine.

3. Automatic switching of the main spare power amplifier, without manual operation.

4. The main and standby networks are paralyzed, go through mode.

5. Multiple design to ensure the normal operation of all the main power transmitters in the system.

PAGA Main System

Type A and Type B connection for Beacon and Speaker

All the beacon feeded power from IPIOBOX1. no need local power feed. Line for beacon only with out speaker.

There is a Connector box connection between the speaker and the alarm lamp.

The alarm light flashes when the speaker is broadcasting.

When the speaker is on standby, the alarm light is standby too.

Each alarm light requires no local power supply. Each light centralized power feeding.

Each alarm light requires a terminal box for wire connection.

Connector terminal box in waterproof grade IP66

Flash light IP66.

Remarks: Audio signal cable 100V standard 2-core speaker wire

The master and backup identities of the same power amplifier can be switched at will

The hardware of the main power amplifier and the backup power amplifier are exactly the same. You only need to choose whether it is the main power amplifier or the backup power amplifier on the software interface, and you can switch between the main power amplifier and the backup power amplifier at will.
