| Frequency Response | 20 Hz – 20 kHz | |
| THD+N (Preamp) | ≤ 0.4% (at 1kHz, 0.775V) | |
| Signal-to-Noise Ratio | ≥ 85 dB | |
| Power Voltage | 160V – 240V, 50/60 Hz | |
| Equalization (per channel) | Low Frequency (LF) | 80 Hz, ±15 dB adjustment |
| Mid Frequency (MF) | 2.5 kHz, ±15 dB adjustment | |
| High Frequency (HF) | 12 kHz, ±15 dB adjustment | |
| Amplifier Section | Output Power | 200W × 2 (at 4Ω load) |
| THD+N (Amp) | ≤ 0.05% (at 1kHz, 80Ω) |
Key Performance Notes:
Dual THD+N Figures: The mixer's preamp section has a distortion figure of ≤0.4%, while the integrated power amplifier boasts a much lower ≤0.05% distortion, indicating a clean and powerful amplification stage.
Wide & Flexible EQ: The generous ±15 dB adjustment range across three frequency bands provides significant tonal shaping capabilities for different sound sources and environments.
Stable Power Output: The 200W per channel (into 4Ω) offers substantial power for driving passive speakers in small to medium-sized venues like conference rooms, classrooms, houses of worship, or mobile DJ setups.
The MX402D is packed with features that enhance its functionality and user experience beyond its core mixing and amplification duties.
Versatile Input Connectivity & Design: The mixer is built on an analog, ultra-low noise circuit design with good headroom. It supports 4/8/12 channel microphone/line inputs, offering flexibility for various setups. A critical feature for studio-grade microphones is the provision of +48V phantom power, allowing direct use of condenser microphones without external power supplies.
Digital Integration and Effects: It successfully bridges analog and digital workflows. The built-in 16 DSP digital effects processor provides a variety of reverb and delay effects to enhance vocals and instruments. Furthermore, the USB access design with an LCD display allows users to directly insert a USB drive to play MP3/WMA files, making it an excellent source for background music or playback.
Professional Output and Monitoring: For master output control, it features a 5-band stereo equalizer. It also includes dedicated outputs for stereo headphone monitoring and recording, enabling real-time mix checks and connection to external recording devices. System status is clearly visible via 2-way high-precision level meters.
Build Quality and Durability: Constructed for the rigors of regular use, it employs high-quality components within an exceptionally rugged construction. The use of 60mm high-grade durable faders ensures smooth, reliable, and long-lasting operation.
The MX402D's integrated design (mixer + amplifier) makes it a perfect all-in-one solution for applications where simplicity, portability, and space efficiency are paramount.
Public Address and Speech: Ideal for school auditoriums, conference halls, and places of worship for clear speech reinforcement.
Portable Performances: Excellent for solo musicians, singers, or mobile DJs performing in cafes, small wedding receptions, or community events.
Fixed Installations: A reliable choice for background music and announcement systems in restaurants, retail stores, or fitness centers.
Band Practice: Provides all necessary inputs for a small band, with enough power to drive practice space speakers and built-in effects for vocal enhancement.
The MX402D stands out in the crowded market of compact mixers by integrating a high-power amplifier (200Wx2) that many competitors omit. While many mixers offer USB playback, the combination with phantom power, multi-channel EQ, and professional DSP effects at its price point presents a strong value proposition. It is positioned as a professional-grade workhorse for users who need an integrated, no-fuss system without compromising on essential features or audio quality.
The LAIKESI MX402D 4-channel power mixer console is a thoughtfully designed, feature-rich audio solution that effectively combines a flexible analog mixer with a clean, powerful amplifier and modern digital conveniences. Its robust technical specifications, highlighted by low-distortion amplification and comprehensive connectivity, are packaged in a durable chassis suitable for mobile and installed applications. For audio operators seeking a single unit to handle mixing, processing, and amplification duties reliably, the MX402D represents a compelling and professional choice.
