Disclaimer

The MR4 ACTIV is intended for professional use by trained clinicians. Users must follow all operating instructions and safety guidelines. This device is not a substitute for medical evaluation or comprehensive clinical care.

The MR4 ACTIV is engineered for professionals who need a powerful, portable, and clinically capable super-pulsed laser system without the limitations of traditional AC-powered units. Combining 905 nm super-pulsed laser emission with 875 nm infrared, 640 nm red, and 470 nm blue LEDs, the MR4 ACTIV delivers a broad therapeutic range suitable for musculoskeletal care, inflammation control, acute injuries, and performance recovery. Its peak output of up to 25,000 mW provides meaningful depth while keeping average power extremely low, maintaining the safety profile of a Class 1M device.

Each wavelength serves a specific therapeutic role. The super-pulsed 905 nm laser drives deep tissue photobiomodulation with minimal heat, allowing safe application over joints, ligaments, and muscle groups. The 875 nm infrared diode supports deeper circulation and metabolic activity, while the 640 nm red LED enhances superficial blood flow and tissue repair. The integrated 470 nm blue LED adds antimicrobial and surface-level healing potential, making the MR4 ACTIV a uniquely versatile multimodal tool.

Designed with mobility in mind, the MR4 ACTIV offers up to eight hours of continuous cordless use, giving clinicians the freedom to treat on the field, in the clinic, or in remote environments. Six built-in presets and Multi Radiance’s signature LaserSweep™ frequency modulation simplify operation, allowing providers to deliver consistent, repeatable outcomes without manual programming.

For sports medicine teams, chiropractors, rehabilitation therapists, and veterinary professionals who need a rugged, portable, and clinically validated super-pulsed platform, the MR4 ACTIV stands out as one of the most capable systems in its class.
