The HumminGuru LUMI Record Stabilizer is a multi-functional Hi-Fi accessory with a built-in ambient light and turntable speed test. Its primary function is to secure the record to the turntable platter with a 300g weight, which improves sound quality by reducing vibrations and resonances, and stabilizing platter speed.
Beyond acoustic benefits, the LUMI enhances the listening environment. Its integrated ambient lighting with 9-color settings casts a soft, adjustable glow from atop the platter or can be used as a standalone accent light, setting a captivating mood for every session.
It also offers practical utility with a built-in stroboscopic light and disc, allowing audiophiles to quickly verify and adjust the turntable's rotation speed. Its rechargeable feature and the handy charging base provide easy charging and neat storage.
With all its features integrated into one elegant design, the HumminGuru LUMI lifts both the sound quality and the joy of the vinyl listening experience!
Ambient Lighting
The LUMI's built‑in ambient lighting can be used on or off the turntable as mood lighting, with 9 color LED lights (red, orange, yellow, green, teal, blue, purple, fuchsia, and an RGB color-changing gradient). This creates a warm, eye-catching visual centerpiece for the setup, enhancing listening sessions and user comfort. Press the center button on top of the stabilizer to activate/change the ambient light, and it will automatically power off after one hour of use to conserve power.
Turntable Speed Test
The LUMI includes a speed test function to verify a turntable rotation speed for precise playback. The test, which requires the LUMI stabilizer and the included 50Hz stroboscopic disc, supports speeds of 33 1/3, 45, and 78 RPM.
Press the right-side button on top of the stabilizer to activate the stroboscopic lighting at its base. Place the 50Hz stroboscopic disc on the turntable platter, fitting it over the spindle. Turn on the turntable and set it to the desired speed (33 1/3, 45, or 78 RPM). Direct the stroboscopic light at the revolving disc from approximately 10cm away and observe the moving markings to verify the speed. Make the speed adjustments as needed.
Observe the Stroboscopic Disc
When the turntable operates at the correct speed, the pattern on the disc will appear motionless. This visual effect occurs because the frequency of the stroboscopic light is synchronized with the speed markings on the disc. If the pattern seems to move slightly forward or backward, the speed is either too high or too low. Use the turntable's pitch control to adjust the speed until the dots appear stationary.
- Stationary dots: The speed is accurate. (Turntable speed setting: 33RPM)
- Dots moving forward (left): The speed is too high. (Turntable speed setting: 33RPM)
- Dots moving backward (right): The speed is too low. (Turntable speed setting: 33RPM)
Rechargeable & Storage
The Lumi is USB-C rechargeable and comes with a practical charging base that conveniently stores the stroboscopic disc.
