Introduction
Your Rega P7 has been designed to be effective, easy to use and above all
- to reproduce music better than any other turntable. We have omitted all the
usual gimmicks and genuinely concentrated the manufacturing costs on the
high quality components and design necessary to reproduce records
accurately.
For example: a complex sub-chassis suspension is normally necessary to
reduce motor noise. However they are difficult to maintain and degrade
performance. Rega have designed a unique phase adjustable power supply
which eliminates motor vibration at source and therefore eradicates the need
for a suspension.
Rega's design skill and the use of extremely high quality components ensure
that your turntable will perform at its optimum. The tips we give here may
help to give you maximum musical enjoyment and ease of use for many
years.

Design Innovation:
Tonearm
The P7 has a new tonearm, the RB700, improving greatly on the previous
model, the RB600. The aluminium tube has been specially coated in a
unique finish and the entire bearing housing has been redesigned and is now
manufactured to even higher tolerances.
The tonearm tube itself (which is a one piece silicone/aluminium casting) is
very rigid, whilst being low mass. The tonearm assembly is concentrated
around precision, hardened stainless steel, miniature ball races of the
highest quality. The bearings fit on to ground shafts and into the tonearm
using interference fits. This means that no adhesive is required and therefore
none of the associated (component - adhesive - component) losses in rigidity
prevail. It is fitted to the plinth by a 3-point fixing which is CNC machined out
of a single solid block of Stainless steel. This provides the strongest most
rigid base structure possible for the tonearm and causes less stress on the
plinth and the RB700's bearing housing, and therefore the least possible
resonance.
The RB700 tonearm is designed to make cartridges work harder, maximising
the cantilever acceleration and travel as much as possible with the utmost
accuracy within the cartridge body thus providing new levels of information.

Hints and Tips
1) Mount the turntable on a
rigid, level surface. A light
shelf or turntable support
(such as our own) screwed
to a wall or in an alcove is
ideal. Avoid mounting on
hollow or heavy cabinets or
anything mounted on a
wooden floor.
2) Try to keep the lid closed
while playing the records.
This will prevent dust falling
on to the records and make
cleaning unnecessary. There
may also be a sonic
improvement.
3) Don't use any record
cleaner that works while the
record is playing or any
cleaners that use water or
solvents. If you keep your
records stored in their
sleeves, avoid touching the
playing surfaces, play with
the lid down and keep all
water and fluids away,
cleaning should not be
necessary. Don't worry about
visible dust on the record
surface, the stylus brushes
this aside and any that
collects on the stylus can be
easily blown away. In
general, record cleaning is
overdone and one should not
believe all the claims made
by
record
cleaner
manufacturers.
4) Leave the turntable
running during a record
playing session. Switch on
before the session and only
switch off after you have
finished. Use the electronic
speed control to change
speeds.
5) Don't lift the centre hub
out from the main bearing.
The bearing is factory
assembled with a film of
special thick lubricant. If the
centre hub is removed this
film may be disturbed.
6) Rega turntables are
designed
to
optimise
performance for music
reproduction and therefore
no compromises have been
made to give quick start
times. The normal time taken
for full speed to be reached
is between 5-10 seconds.
11
7) The arm earth (or ground)
is automatically connected
through the arm cable
screening. No other earthing
should be necessary.
8) Save the original packing
in case you ever need to
transport the turntable.
9) Don't use any polishes on
the turntable or lid. To clean
or dust, wipe gently with a
soft cotton duster (slightly
damp only if necessary).
10) Always deactivate the
power
supply
before
disconnecting the turntable.
Should you experience
any problem with your
turntable or wish to
enquire about servicing
please contact your
Rega dealer.

Caring for your P7:
Service
To keep your P7 working perfectly, please ensure that your turntable is
returned to a Rega trained dealer for servicing at the recommended interval
periods (2000 hours playing time).
Transporting your P7
Should you need to transport your P7, to avoid any possible transit damage,
the following recommendations must be followed.
1. Remove tonearm balance weight and secure the arm in its rest with tape
or covered wire. This will ensure no sudden or violent movement is
transmitted to the delicate bearings.
2. Remove ceramic platter. When removing, hold down the metal hub at the
same time as lifting the platter on each side. When removing or replacing,
ensure it is done evenly to avoid chipping to the platter.
3. NEVER place your P7 upside-down or on its side. This would allow oil in
the hub/bearing assembly to leak and cause speed and or wear problems.
4. If you have to ship your turntable or use a carrier, use ALL the original
packaging. If in doubt ask your dealer.

Platter
The platter is produced from a ceramic oxide powder which is compressed,
fired and diamond ground to size. (Because this platter is as stiff and hard
as sapphire, the only improvement that can be made would me to make it
from diamond.) This is a first in the industry at volume production levels.
Even so, each platter takes many hours to produce. Expensive detail design
ensures it only sits on three points on the centre hub. We have also used
new techinics to achieve better speed stability of the turntable by using
ceramic weights to provide a flywheel effect to the platter.
Plinth
The new P7 plinth is made from an even lighter material than the original
Planar which again offers advantages over its predecessor. The plinth is of
a skeletal design. This allows the mass to be reduced and the rigidity
increased in comparison to a solid section construction. All organic materials
used in the production of the plinth and surround are obtained from
sustainable sources.
Motor
The motor is a high specification, P9 24V twin phase synchronous unit
controlled by Rega's unique and innovative TT PSU power supply. The motor
drives the computer-numerically-controlled (cnc) machined pulley and sub
platter/hub-bearing assembly via a twin belt drive. Two belts are used so that
any small inaccuracies in one belt will be cancelled out by the second, giving
unusually low levels of wow and flutter.

Interconnects
We have used the highest qualitypurpose designed high current power and
phono connectors and low noise, wide bandwidth interconnect cable. These
are genuine professional products and are the best available for the job. Do
not attempt to fit any other wires or cables.
Power Supply
The compact TT PSU uses exactly the same high stability crystal locked low
distortion sine wave generator as is used in the heart of the P9 power supply.
This, along with an efficient drive amplifier fed from a stabilised DC power
supply, generates a 24V AC balanced signal of less than 0.05% distortion,
which is completely un-affected by any changes in the mains/line voltage
and conditions. This then drives the improved Rega anti-vibration circuit,
which is situated beneath the turntable.
The speed change is achieved by changing the frequency of the drive
voltage; this is because the speed of the platter and motor is directly
proportional to the motor drive frequency. A relay switches in the required
phase compensation & anti vibration circuit to eradicate motor vibration to a
minimum at both speeds.

The recommended tracking force can now be applied by means of the tracking
force control - always use a force which corresponds to the upper limit of the
cartridge makers recommended range.
Set the bias adjustment slider to the same number as the tracking force control.I.e. 1.5 g tracking force = 1.5 on the bias slider.
Your turntable is now ready to use.

Set tracking force.
Fit the cartridge to the tonearm (this should have been done
by your hifi dealer!).
Note: If you are going to use another manufacturer's
cartridge, please be aware that they may use deeper
bodied cartridges than our own. It may be necessary to add
our "Rega Arm Spacers" to obtain correct VTA (Vertical
Tracking Alignment). 2mm, 4mm and 10mm sizes are
available and a sleeved arm nut is supplied for use with
4mm and above. The spacers simply sit underneath the
arm raising it to the required height.

See page 7 for Turntable diagrams.
With the cartridge fitted using the alignment protractor
supplied, ensure that the tracking force control and bias
adjustment slider is set to zero. Slide the balance weight
along its shaft until the stylus is "floating" just 1mm clear of
the record. It is worth noting, that the tonearm will drift back
to the bias housing; this is perfectly normal due to its virtually
frictionless bearings.

Power Supply/Turntable setup:
The tips we give here will help to give you maximum musical enjoyment and
ease of use for many years.
Carefully remove the turntable from the packaging.
Place the turntable on a flat surface, (see hints and tips).
Ensure the tonearm interconnects are connected to your amplifier (switch
amplifier off first).
Connect TT PSU to the mains using the lead supplied.
Connect the turntable power interconnect from the PSU to the turntable.
Make sure the mains transformer is plugged in and connected to the PSU switch on.
Push the power button on the back of the PSU to turn on:
When the power supply is switched on, the front power L.E.D. switch will light
up red. This also indicates that 33 rpm is selected. To deactivate 33 rpm
press the button inwards, this will turn the L.E.D. to green and will have
selected 45 rpm. To deactivate 45 rpm press the button again and the L.E.D
will return to red re-selecting 33 rpm.
To switch off at any time, simply press the power switch on the TT PSU.
