VA 6100MS 8 Channel Changeover

€2.168,00

VA-6100MS changeover integrates the main and standby power amplifier conversion functions, ground detection, open circuit detection, and short circuit detection of the speaker circuit. It is also compatible with three-wire and four-wire volume controller wiring. It does not require additional wiring and power supply, and has 8-channel programmable dry or wet node trigger inputs and 8-channel programmable online output signals. The controller can be combined with Class D digital amplifiers and traditional analog amplifiers to build a user audio amplification system, providing a safe, stable, and economical solution for the system.

Features:

* It adopts 2U chassis with highly integrated and modular design.

* Supports real-time detection of speaker loop grounding, open circuit and short circuit, and automatic protection of the amplifier 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.
