DMA2100 / DMA220 / DMA2300 / DMA21M Smart Audio Solution for Government and Enterprise Training Rooms




  I. System Overview


Traditional training rooms often face challenges such as fragmented audio management, high maintenance costs, complex on-site operations that disrupt training sessions, unstable audio transmission that affects teaching effectiveness, and rigid system architectures that struggle to scale with evolving business needs and new application scenarios.



Project Requirements

● HD Audio Reinforcement: Equipped with digital DSP amplifiers, the system supports multiple audio inputs and features anti-feedback and limiter functions to ensure clear and stable audio quality for lectures and multimedia playback.
● Local Control: A wall-mounted control panel enables quick source switching, volume adjustment, scene selection, and one-touch muting for simple and convenient operation.
● Remote Management: Supporting network connectivity, the system enables remote power control, status monitoring, fault alerts, and centralized volume adjustment, allowing unified intelligent management of multiple training rooms.
● Stable & Reliable: Featuring overload, short-circuit, and over-temperature protection, the system supports long-term continuous operation and is ideal for high-frequency training environments.

 Solution Overview


System Architecture:


The solution is composed of two core components: a centralized management and control center and independent audio reinforcement units deployed in each training room.




Management and Control Center


A management computer equipped with dedicated management software enables centralized monitoring and control of all training room audio devices via the LAN. It allows administrators to view device status, remotely power on/off devices, select audio sources for different zones, and adjust volume levels by zone, significantly reducing operation and maintenance costs.


Independent Audio Reinforcement Unit for Each Training Room (Standard Configuration)


● Audio Pickup Device: The D5815 Wireless Microphone System, including the D5811 Handheld Microphone and D5812 Lavalier Microphone, captures instructors' voices wirelessly and connects to the amplifier microphone input channel via an audio cable.
● Main Control Device: The DMA2300 Dual-Channel Digital DSP Mixer Amplifier integrates pre-mixing, DSP audio processing, and power amplification into a single unit. It supports multiple audio inputs, including Bluetooth, line input, and digital audio, and features built-in feedback suppression, limiter, equalization, and other advanced audio processing functions.
● Local Control Panel: The DMA21M Smart Touch Wall Control Panel connects to the amplifier via an audio control cable, allowing instructors to switch audio sources, adjust volume, change scenes, and mute the system with one touch directly in the training room, without accessing the equipment room amplifier.
● Audio Reinforcement Terminals: A variety of speakers can be flexibly configured according to different training room sizes and layouts, including the DSP7908 Full-Range Speaker, DSP6050 Wall Mount Speaker, and DSP8060C Ceiling Speaker. These speakers are connected to the amplifier’s power output terminals via dedicated speaker cables to ensure uniform sound coverage throughout the room.
