The Details Related Solution Related Cases Related Video Download

Descriptions:

The 8-zone power amplifier has a built-in 500W digital power amplifier and integrates 8 independent power zones. It can be installed in the broadcasting room or remote machine room, and is connected to the system via Ethernet to share the network audio source. It also allows 4-channel local audio input, making it the preferred device for building small and medium-sized broadcasting systems.

Features:

* Supports speaker loop grounding, open circuit and short circuit detection, and automatic amplifier protection in case of short circuit fault.

* Supports 3/4-wire speaker loop wiring, fire alarm broadcasting, audio control and forced cutting, and maximum volume output.

* It has 8 programmable trigger input online interfaces, which can trigger the pre-programmed voice messages to the specified partitions.

* It has 8 programmable trigger output online interfaces, which can output short-circuit voltage-free relay control signals to third-party equipment to achieve online automatic control.

* Supports the amplifier to enter power saving mode when there is no signal input to save energy.

* Supports connection with linkage fire alarm controller to realize fire alarm linkage control.

* Provides a DC 24V backup power input interface (24V DC power provided by an external DC power charger) to realize main and backup power supply.
