Adjusting The Speed - Rega P6 Mode D'emploi

SPEED ADJUSTMENT (FACTORY SET
- ONLY ADJUST IF NECESSARY)
The speed control functions are sited on the back panel of the Neo:
Speed program switch: This enables the set speed mode.
Program mode LED: This indicates the two modes of operation:
Factory default mode and speed adjustment mode.
Speed adjustment: This encoder is used to adjust the
speed. The step size of the speed control is 0.01 rpm.

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 program' switch on the rear panel
once to put the unit into setup mode - The 'program
mode' LED will now be permanently illuminated red.
3. Adjust the speed via the 'speed adjustment' control using a 1.7
mm 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
program switch' once to put the unit back into 'run mode'. The
'program 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 down the 'speed program' switch until
the 'program mode' LED flashes every few seconds. Keep
the button pressed until a solid LED is illuminated.
3. Whilst illuminated, press the 'speed program' switch button
once again to fully factory reset and return to 'run mode'.
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 100 Hz.
USING THE STROBE KIT
Simply place the strobe disc on the turntable platter. Switch on the
100 Hz LED and hold it approximately 2 cm above the rotating strobe.
If the bars do not appear to move and are stationary, the speed is
331/3 rpm. If they move clockwise, the turntable is running fast, and
conversely, if they move anti-clockwise, 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.
WARNINGS
Do not unplug the power supply from the turntable whilst the unit
is on - turn off the power supply before unplugging. Do not operate
the power supply without the turntable connected. A 24 V AC plus a
20 V DC signal present on the pins of the plug - if these are shorted
it will cause damage to the power unit. Use only with the Rega PS1
power supply or Neo. Never expose the unit to rain or moisture. Do
not open the case covers. There are no user serviceable parts inside.
The Neo incorporates resettable fuses in the driver
amplifier to protect it from overcurrent faults, which will
cause the turntable to run erratically or not at all. If in the
rare circumstance these are activated, they are reset by
turning off the Neo via the front panel for approximately 10
seconds. If the fault should persist, consult your dealer.
