XONE VF-1
RIAA Option Fitting Instructions
1
An RIAA pre-amplifier compensates for the characteristics of vinyl reproduction by attenuating the high
and boosting the low frequencies, according to the standard slope specified by the Recording Industry of
America.
The XONE VF-1 is available with a factory-fitted RIAA preamp option to allow a high quality magnetic
cartridge turntable to be used as an input to the unit.
This option is only available on units fitted with
an issue 4 (or later) main PCB.
The issue number is printed on the PCB, and can be checked by
looking through the ventilation slots on top of the unit, without the need to remove the cover.
Retro-fitment of the RIAA option is possible – this involves removing the unit’s cover. Due to the mains
voltages present within the unit, this is not considered a task for the end user. These instructions are
provided for reference –
any work on the internal parts of the unit should be carried out by
technically competent personnel.
For information on how to use the
XONE VF-1
please refer to User Guide AP5917. Should further
assistance be required, please contact Allen & Heath Technical Support (details on our web site
www.allen-heath.com).
Before Starting
Read these fitting instructions carefully before starting. For trouble free installation and operation heed all
the precautions noted. The unit must be fully unplugged and removed from its rack, plinth or other
furniture before carrying out the work. Normal workshop tools are required, including a Torx (starhead)
T10 screwdriver. Provide a suitably large, well lit work surface such as a service workshop bench. To
avoid damage to the cosmetics of the unit ensure that the work surface is clean and clear of obstructions.
Allow enough time to carry out the work properly and test the results.

003-360 x1 RIAA Option circuit assembly
