Solar network sound column; Built in embedded network audio decoding module, which completes the reception and decoding of network audio streams;
Adopting high-speed industrial grade 1GHz SOC chips.
Built in embedded network voice decoding module, dual channel output amplifier, differential output stereo signal purity.
Select multiple different host audio source programs and play them locally; It can play broadcast programs from its own host, including paging, fire alarm automatic insertion, etc.
IP addresses can be configured statically or dynamically to obtain; There is a unique encoding sequence number that can receive personalized timed playback programs from the server separately, or can be grouped arbitrarily.
Digital audio input, high fidelity sound quality, and the ability to reproduce the true amplification of human voice and music. Equipped with intelligent power management function, the device adopts a built-in low-power CPU with a standby power of ≤ 3W. When there is a playback task, the imported digital amplifier chip has a conversion efficiency of over 90%, with low heat generation and long lifespan. Using imported Jimei audio coupling capacitors for good sound reproduction and quality. The physical volume of the device has a remote adjustment function. When the terminal automatically starts and plays tasks, the tasks also have independent volume management, so there is no need to repeatedly adjust the physical volume. One line for multiple uses, fully utilizing existing network resources, avoiding redundant installation of lines, compatible with TCP/IP network protocol, can be connected to any location on Ethernet, truly realizing the integration of broadcasting, computers, monitoring networks, etc., and supporting cross gateway, cross routing, interconnection through network connection to set IP addresses and network configurations.
Featured features: Supports remote hyperlink sound source playback [convenient for subsystem secondary development and calling] [optional],
1: Distributed decentralization allows each client to be an independent entity, and multiple audio service network nodes can be added. Device unique address authentication encoding addresses can be added as authentication. Easy to expand with no quantity limit.
2: Add scheduled tasks, daily tasks, monthly tasks, single tasks, and event triggered tasks. The task can be set with a start date and a stop date, with weekly and monthly blocking positions. The task content can be played for a limited time, randomly, or in a sequential loop.
3: By clicking on the broadcast, you can temporarily select certain devices for live streaming based on actual needs, such as computer sound card sound or microphone speech.
4: Partition broadcasting, select pre-set areas for fast broadcasting of the entire area.
5: Sound pickup function: [module optional] a. It can be used for environmental sound monitoring; b. You can forward the environmental sound to a certain audio device or a group of audio devices for long-term monitoring. c. Can conduct full duplex two-way intercom. Adjustable microphone sensitivity with 64 levels of amplification and an ultra wide pickup range.
6: Alarm linkage: The entire range of equipment supports dry contact alarm input, which can collect and feedback the alarm signal information recognized by the Hikvision camera to the system for recording, and at the same time, the point alarm information is highlighted in red. The monitoring computer emits an alarm sound, which can be set as message recording or trigger a task based on the specific content of the point, to broadcast the specified content to the designated broadcasting equipment group. At the same time, the on duty personnel can quickly shout at the alarm point.
7: Video linkage: Add NVR streaming media RTSP or RTMP streaming addresses within the local area network for large screen monitoring. Each video is bound to a set of broadcast speakers, allowing for immediate broadcasting upon viewing.
8: Choose

Configure cache unit

After playing the audio file once, it is cached locally and intelligently managed to keep files with high usage frequency and automatically clear files with low usage frequency [saving bandwidth and data consumption, such as suitable for playing background music/advertising audio for a long time, or playing anti black and anti evil activities]
