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
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.
