IP network terminal EV-9003
Product Overview:
Receive and amplify network audio signal, local amplification and network audio in one. Commonly used in the use of power is large, such as school sports ground or outdoor green belt and other places, common in the network after the pre-amplifier with pure post-broadcast amplifier used together.
Detailed parameters:
● Adopt network audio module high quality digital audio transmission,
● Automatically turn on or off the power of the external power amplifier according to the sound.
● Built-in three-level signal priority function:
Local signal priority (local input signal priority, and the priority level can be preset, network music plays the role of background sound)
Emergency broadcast priority (network control audio source, can achieve timing playback, network control audio source, can achieve timing playback, emergency broadcast priority input, the broadcast signal will automatically close the local input signal, play network emergency broadcast signal)
Local signal mandatory priority (in the case of emergency broadcast, can start the local mandatory priority function, to achieve artificial local emergency broadcast function).
●1 channel network signal input; 2 audio signal output; 5 channels microphone 1 channel power control;
● Extensible connection of four power amplifiers
● To achieve cross-gateway device control: each channel independent control volume, strong interpolation priority silent sound.
