This power amplifier unit is an 8-channel IP power amplifier. The output power of each amplifier channel is adjusted according to the connected speaker load, limited only by the overall power budget of the whole amplifier The units is connected to the central exchange unit via Ethernet CAT5 or CAT6 or fiber cable.The amplifier is a Class D power amplifier due to its especially high efficiency, low power consumption and long life.
This network public address system is suitable for tunnels, docks, factories, schools, Hospital,subways and other places where the environment is harsh and noisy.

IP Amplifier, 600W 4/8-channel Class D power amplifier
The amplifier adapt the maximum output power of each amplifier channel to its connected loudspeaker load,with freeassignable output power per channel for a total maximum of 600 watt per amplifier, supporting 100 V operation with direct drive capability and outputs.
The amplifier have a built-in independent spare amplifier channel for automatic fail over.The amplifier
with dual Ethernet ports for redundant network connection.
The amplifier with automatic fail over to an analog lifeline input
The amplifier have dual power supply inputs and power suppliers.
The amplifier have front-panel Light Emitting Diode (LED) indications status
The amplifier is rack mountable (2U)
The amplifier is certified for EN 54-16 and ISO 7240-16, marked for CE and be compliant with the ROHS directive orequivalent.
Flexible collocation :
Independent amplifier channels; integrated standby channels can be enabled
automatically in the event of channel failure;
Primary and standby redundancy:
when the IP amplifier plays audio sources, the standby channel can replace any damaged audio channel at any time, whichever fault occurs first.
When the damaged audio channel is restored, the alternate channel can replace another damaged channel.
1. Primary and standby redundancy:
when the IP amplifier plays audio sources, the standby channel can replace any damaged audio channel at any time, whichever fault occurs first.
When the damaged audio channel is restored, the alternate channel can replace another damaged channel
2. 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.
3. Integrated loudspeaker loop monitoring.
