The DB3000 digital mixing console is a series of products tailored for Chinese broadcasting institutions, including the DB3000S (upgraded version), DB3000S (classic version), and DB3000E (compact version). The DB3000S (upgraded version) and DB3000S (classic version) adopt a plug-in chassis structure, with custom optional interface cards and support for hot plugging; DB3000E (compact version) is a fixed interface form; All three mixing consoles can be equipped with a control panel that supports electric thrusters.
· Excellent technical architecture
The core architecture of distributed FPGA+DSP uses SHARC floating-point processor as the main DSP, with SIMD core and hardware acceleration functions such as IIR filter enabled
The deeply optimized Linux kernel supports superior human-machine interface and reliable network communication mechanism; Modular and split structure design can meet the needs of different scene configurations
· Stable security strategy
Redundant power supply and hot swappable mechanism, built-in network switch to ensure long-term stable operation of the system
Equipped with multiple alarm and recovery technologies such as shutdown, clipping, and reverse equalization, it accelerates the detection and handling of faults
Equipped with hierarchical permission management function, it can prevent broadcast suspension accidents caused by misoperation
· Remote monitoring and management
A second pre listening/monitoring bus has been added to the core routing, which can be sent to the remote end through the network to view the current status of the mixing console and the level changes of input and output signals in real time
Complete lossless monitoring of input and output buses without affecting broadcasting, and can also perform remote configuration, error correction, and takeover under authorization
The system uses AES70 open remote management architecture (customizable NMOS protocol by users), which can be managed and routed by third-party systems
· AoIP cloud mixing console
Equipped with AoIP function, capable of bidirectional transmission of 24 bit uncompressed digital audio signals through the main control board in both primary and backup modes
Customizable selection of AES67+AES70 or other modules, with 64 in and 64 out AoIP channels and latency less than 5 milliseconds
Equipped with device interconnection function, under the action of network management software, it can realize resource sharing, routing backup, collaborative processing and other applications
Features
Networked, modular, and split broadcast grade digital live mixing console
Meets the Level I requirements of the new version of the "GY/T 274-2013 Digital Mixing Console Technical Specifications and Measurement Methods" standard
Primary and backup AoIP interfaces, following GY/T 304-2016 (AES67) and GY/T 322-2019 (AES70) standards, can support other protocols by replacing modules
Support MADI bidirectional access, facilitating multi-channel interconnection with other devices
A complete busbar structure, including PGM, REC, N-X, AUX, MONITOR, etc., with 4 monitoring and 4 intercom channels, totaling 10-16 stereo busbars
Each channel has A/B selection (or 16 out of 1), phase correction, equalization, and dynamic switching
Dual power supply redundancy design, no single power node, blade power supply supports hot swapping
Fanless design, ultra quiet operation, suitable for use in recording and studio rooms
The pusher and control module use a high contrast, wide viewing angle color TFT screen as the display unit
Select high-end products for the pusher (P+G, ALPS optional)
Dedicated watch bridge design, industrial grade quality, equipped with a multi-point touch capacitive screen, flexible and convenient operation
The device does not rely on a table bridge during normal operation, and the table bridge can be used for parameter configuration and real-time monitoring
Built in network switch, capable of control and management through AES70, facilitating user integration and monitoring
When the audio chassis loses network connection, it automatically maintains its current state without interrupting local sound
Loudness meter and true peak meter that comply with national standards and ITU-R standards, the mixing console has automatic mute function, with a loudness meter
NTP Network Standard Inter inch Synchronization Technology
