  • Standard 2U rack-mount design featuring a metallic painted steel panel, offering a cost-effective yet premium appearance.
  • Available power configurations: 2×150W/8Ω, 2×250W/8Ω, 2×350W/8Ω, 2×500W/8Ω, and 2×650W/8Ω; all models support 4Ω loads.
  • 2.8-inch color LCD display.
  • Primary operations are performed via a jog dial, with independent volume buttons for each audio source to facilitate convenient adjustment; user-friendly interface design minimizes the risk of misoperation.
  • Two 6.3mm microphone inputs with independent volume control, reverb effect processing, and 10-band digital equalization per channel.
  • Two rear-panel balanced microphone inputs featuring independent volume control, reverb processing, and 10-band digital equalization (adjusted after mixing with the 6.3mm inputs). These inputs offer selectable 48V phantom power (with independent switch control) and input sensitivity options of 5mV or 250mV to accommodate both conference and handheld microphones.
  • Three audio line inputs, each with independent volume control and 10-band digital equalization.
  • One stereo audio line output with various preset EQ effects available after mixing.
  • The three line inputs can be mixed with the four microphone inputs and MP3/BT sources for flexible output routing.
  • Bluetooth and MP3 playback with support for USB and Micro SD cards (compatible with MP3, M4A, WAV, APE, and FLAC formats, including lossless formats up to 44.1kHz/48kHz 16-bit); each source features independent volume control and 10-band digital equalization.
  • Built-in anti-feedback functionality for microphone inputs.
  • Microphone priority function offers six mixing depth levels: 100% (original mix with AUX and MP3 signals), 70%, 50%, 30%, and 10% (AUX and MP3 signal levels reduced to 70%, 50%, 30%, and 10% of full volume, respectively), and MUTE (AUX and MP3 signals reduced to zero).
  • RS485 remote control support for comprehensive volume and equalization adjustments.
Overview Specifications Related Products Solutions Latest News & Cases

The conference digital mixer amplifier is a series of public address amplifiers integrating equalization, pre-amplification, and post-amplification functions. The entire series has been redesigned with a contemporary aesthetic, featuring all-digital amplifier architecture. Each model is equipped with a 2.8-inch color LCD screen and a rotary encoder (jog dial) for intuitive user interaction, along with independent volume control buttons for each audio source, enabling straightforward level adjustment. The series maintains the original power output while achieving cost efficiency comparable to the previous generation, significantly streamlining the complex front-panel layout of the MK69 series and offering a more user-friendly human-machine interface. The expanded power range and integrated RS485 remote control capability have broadened the application scope of these amplifiers.

This product series is equipped with 3 stereo input ports, 2 6.3mm microphone inputs, 2 XLR microphone inputs, 1 stereo line output, 1 recording output, and 2 amplifier output terminals. Bluetooth/MP3 playback, 3 stereo channels, and 4 microphone inputs each feature independent volume control with 10-band digital equalization per channel. After mixing the three audio sources, independent EQ presets with a variety of effects are available. The microphones incorporate anti-feedback functionality, and the amplifier provides a master output volume control.
