Adjusting The Speed - Rega Planar 6 Manual De Instrucciones

Adjusting the speed

Note: We recommend the Rega strobe kit to accurately measure the
speed during adjustment (sold separately).
Note: The speed is adjusted whilst running at 331/3 RPM and any
adjustments made at 331/3 RPM will be automatically be applied to
45 RPM.
1. Select 331/3 RPM.
2. Press the speed programme switch on the rear panel once to put
the unit into setup mode - The 'Programme mode' LED will now be
permanently illuminated red.
3. Adjust the speed via the speed adjustment control using the
supplied 1.7mm allen key. Turning clockwise will increase the speed
and turning counter clockwise will decrease the speed. The step
size is 0.01 RPM. Only make small adjustments of up to five 'steps' at
a time to ensure accurate adjustment. Check the speed after each
adjustment to achieve the best accuracy.
4. When the speed has been correctly set, press the speed
programme switch once to put the unit back into run mode. The
programme mode LED will now go out and flash approximately
every ten seconds indicating the speed has been changed from the
factory setting. Your turntable is now set and ready to use.
Returning the Neo to factory settings
This process is recommended when fitting a new drive belt to your
turntable or after a service to help optimise the range of adjustment
available to you.
1. Select 331/3 RPM.
2. Press and hold the speed programme button for ten seconds.
3. During the first five seconds, the LED will illuminate solid followed
by flashing for the final five seconds, before returning to solid.
4. Press the speed programme once more to return to 'run mode' . The
unit is now reset to factory default.
Note: We recommend changing Rega drive belts every five years to
guarantee optimum performance. Using the Neo with old worn belts
may result in lower performance and variation in speed stability.
Use of mobile phone apps to check and adjust
the speed
Rega, along with a London mastering studio, have used the iPhone
RPM app (available on the App Store) developed by Philip Broder
to check and adjust the speed of a turntable using the Neo, with
positive results. We have verified the basic accuracy of the RPM app
using Rega's in-house speed measuring equipment, but as this is
a third-party app we cannot guarantee the readings because of
uncertainties, which could be caused by the age, condition, and
operating system of the phone the app is installed on. If you are in
any doubt, you should check the calibration of the RPM app using a
suitable reference.
Rega Strobe and stroboscopic disc (sold
separately)
The best way to adjust the speed of your Planar 6 is to use the
Rega Stobe kit. A stroboscopic disc is an optical instrument used to
measure the speed of the turntable by freezing the bars on the disc.
The bars are illuminated by an accurate quartz locked LED pulsing at
100Hz.
Using the Strobe kit
Simply place the strobe disc on the turntable platter. Switch on the
100Hz LED and hold it approximately 2cm above the rotating strobe.
If the bars do not appear to move and are stationary, the speed is
33.33 RPM. If they move to the left, the turntable is running fast, and
conversely, if they move to the right, the turntable is running slow.
If over one minute the bars appear to move by one bar to the left or
one bar to the right, the speed is 0.016% fast or slow respectively.
Using the speed control on the Neo it is possible to achieve +/-
0.05% or +/- 1.3 RPM.
Note: If over one minute the bars appear to move by two bars to the
left or by two bars to the right, the speed is 0.01 RPM fast or slow
respectively. Using the speed control on the Neo it is possible to
achieve +/- 0.01 RPM, which is one step of the speed adjustment.
Warning: Because of the nature of the stroboscopic effect of the disc
and the LED light, we strongly recommend anyone with photo-
induced epilepsy not to use this device. Although this condition is
very rare, we must make the user aware of this condition. Ask your
dealer for assistance if required.
