Operation

There are now two modes of operation that allow you to change speeds without stopping the turntable, one of which also allows you to mute the phono stage while you change record. A switch at the back of the Radikal allows you to select between the following modes:

  • Normal Operation:
    • When the LP12 is powered off, a short single press of the LP12 switch will start the deck on 33 rpm mode
    • When the LP12 is running, a long press and hold of the switch will change the speed to 45 rpm
    • When the LP12 is running, a long press and hold of the switch will return the speed to 33 rpm
    • When the LP12 is running, a short press will power off the LP12


  • Enhanced (With Mute):
    • When the LP12 is powered off, a short single press of the LP12 switch will start the deck on 33 rpm mode
    • When the LP12 is running, a short press will apply a soft mute (-25dB) to the phono stage while you replace the stylus. The LED will flash when muted – simply press again to restore volume.
    • Press and hold for a couple of seconds to change speed to 45 rpm. A short press will enable and disable mute as above.
    • Press and hold for a couple of seconds to return speed to 33 rpm, or longer to turn the LP12 off.



  • LED Behaviour:
    • The red LED indicates 33 rpm mode
    • The green LED indicates 45 rpm mode
    • A bright LED indicates that the Radikal is adjusting and calibrating the speed
    • A dim LED indicates that the LP12 is running at the correct speed
    • Either LED is flashing indicates in soft mute mode.


  • Power Up: The first time the Radikal powers on it will use a default value to set the initial motor speed at 33 rpm. Calibration is then performed every few rotations, allowing the platter speed to settle between adjustments, until properly calibrated 33 rpm has been achieved. The calibrated setting for that LP12 is then saved in memory. This process usually takes around a minute. On subsequent power ups the most recently generated calibrated speed setting is recalled from memory and used as a starting point. Getting up to calibrated speed at 33 rpm from stationary then usually takes about half a minute (some time to reach speed, then a few calibration cycles to check and refine the speed). The results of this calibration cycle are then stored to memory.


  • Startup Mode: On startup the deck only ever spins at 33 rpm until it gets up to this speed, which usually takes about half a minute. Only after this will it attempt to adjust the speed if 45 rpm has been selected. Even if 45 rpm has been selected during the startup period and the LED has gone green, it won’t actually try to change the speed to 45 rpm until 33 rpm has been achieved.


  • Operational Mode: If the platter is stopped or slowed down during operation (something which should not be done), the Radikal will always revert to 33 rpm mode to recalibrate. Only after it has achieved 33 rpm will it switch back to 45 rpm mode if applicable. The LED does not turn red to indicate that it has switched to the 33 rpm calibration cycle if the LP12 is running at 45 rpm.


  • Changing Speed: If the LP12 switch is used to change the speed between 33 rpm and 45 rpm, the speed change happens within a few seconds; the calibration is what takes the extra time. The Radikal will not attempt to change the speed to 45 rpm until it has callibrated at 33 rpm. If it appears to be taking longer than expected, it’s possible that the deck is calibrating at 33 rpm before attempting to change to 45 rpm.

Your Linn Radikal will need to be installed and configured by your Linn retailer.

Note
The motor used with the Radikal (2009 variant) and Radio (2021 variant) are different and not interchangeable. Therefor a Sondek that has been installed with a Radikal (2009 variant) motor needs to have this updated to work with a Radikal (2021 variant)
