Mixer Amplifier 240W TOA A-3524D
คุณลักษณะของ Mixer Amplifier 240W TOA A-3524D
- A-3500D amplifier can be a local amplifier integrated with a building-wide voice alarm system. As the amplifier receives the emergency signal, which can automatically override the local sound, emergency messages will be delivered at the maximum level regardless of master output volume settings.
