Know before you buy
The device uses a hall effect sensor paired with a small magnet placed on your platter. This allows it to track rotation with extreme precision and report the speed to three decimal places on the LED display.
Yes, the Roadrunner is designed as a universal tool. Because it relies on an external sensor and magnet system rather than a specific connection to the turntable's motor, it can be used to verify speed on virtually any turntable.
When connected to a compatible Condor PSU, the Roadrunner acts as a feedback loop. This allows the system to automatically adjust and lock your turntable's speed to within 0.005 RPM, providing a level of stability that manual adjustment cannot achieve.
Absolutely. By tracking the total hours your turntable has been in operation, it provides a reliable metric for knowing when to replace your stylus or perform routine maintenance, ensuring your records are always played with a fresh needle.
The unit is quite compact, measuring approximately 3.5 inches long by 2.5 inches wide. Its small footprint and aluminum construction make it easy to place near your turntable without cluttering your setup.
The Roadrunner features multiple operating modes, including a sleep mode. You can use the device to verify your speed during setup and then dim or disable the display to ensure it doesn't distract from your listening experience.
