SETUP – GETTING STARTED
Switch the mains power on. Push the power button on the front panel to turn the Neo on - When the
power supply is switched on, the Rega logo will illuminate RED. Red indicates that 331/3 RPM is selected.
To change to 45 RPM, press the 33/45 button, this will turn the Rega logo to GREEN and will select 45 RPM.
To re-select 331/3 RPM, press the button again.
IMPORTANT: When using the Neo, always position the drive belt in the 331/3 top position of the drive
pulley as shown.
To minimise the risk of hum being picked up by the cartridge, the Neo should be situated as far from the
turntable as the cables will allow.

SPEED ADJUSTMENT

Speed control adjustments are located on the rear panel of the Neo.
Speed programme switch – This enables 'set speed' mode.
Programme mode LED – This indicates the two modes of operation: Default mode (factory speed setting)
and running in the speed adjusted mode.
Speed adjustment – This adjusts the speed. The step size of the speed control is 0.01 RPM.
IMPORTANT: If your drive belt is five or more years old it's highly recommend that it is replaced as this can
cause small inconsistencies in speed which could prevent optimum adjustment when setting the Neo.

MEASURING THE SPEED
Rega Strobe Kit (sold separately)
The best way to adjust the speed of your turntable is to use the Rega Strobe 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.
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.
