Amber SL404 Overview
Amber series powered speakers are designed for intelligent network system construction and have digital and analog dual-link backup inputs . This series of powered speaker uses TENDZONE's proprietary audio processing technology to achieve natural sound playback and inherit TENDZONE's good sound quality .
It uses TENDZONE Vailink network transmission protocol and realizes network audio transmission through the RJ45 network interface. It also has an XLR-Fanalog input interface, which serves as a link backup for network audio transmission, with network priority and automatic switching. It provides stable and safe protection for major integration projects.
Features
Basic Functions
- Built-in digital signal processing, using Chinese Rockchip ARM as the processing and management core
- Built-in dual-channel intelligent digital power amplifier, the speaker is driven in bi-amp mode
- Adopting Vailink network audio transmission protocol, it seamlessly connects with AI audio algorithm processing service platform. The platform design software can uniformly design signal routing and management, manage multiple devices in a unified manner, and remotely switch devices on and off
- 2 Vailink gigabit network interfaces, supporting dual-link redundant backup. If one link fails, it will automatically and seamlessly switch to the other link
- 1 XLR analog input interface , automatically switches to analog input link when network links fail
Operation and Maintenance Management
- Built-in electret omnidirectional professional test microphone to monitor the sound restoration status of the speaker in real time
- The platform software can remotely monitor the working status of the speaker, including: output current, output voltage, temperature, output protection status warning, amplifier module channel mute status display, output limit warning
- It has the function of device search, which can be queried remotely and let the device display location reminder
- Color LCD display, which can display device information and parameters, and can turn pages and confirm parameters through encoder
