Foreword
Analog music experience
The STUDIO MASTER T700 turntable is a high-end turntable with innovative
technologies. It is made exclusively from materials of the highest quality in
Germany and distinguishes itself through its clear, elegant, and timeless
design. It is top of its class and provides music lovers with an impressive,
audiophile music experience. Thanks to the built-in phono preamplifier, the
T700 is compatible with all Revox products – such as Joy S119, Joy S120, and
also the M series as well as with products from the past (Evolution, Emotion,
Exception, B series) and can be easily integrated into a Revox Multiroom and
Multiuser System. It is also compatible with other conventional audio
products.
Integrated phono preamplifier
A special highlight of the STUDIO MASTER T700 is the unique, integrated MC
phono preamplifier. The integration of the preamplifier enables the best and
shortest connection between the pick-up and preamplifier and thus leads to the
highest signal quality while preventing interference. For this purpose, the
tonearm strand, for instance, is tightly twisted and directly soldered to the
input of the preamplifier. In addition, there is a galvanically separated
power supply for the phono preamplifier and the motor control, which prevents
mutual, negative interference.
Electronic speed control
To ensure the best sound quality, absolute speed accuracy is essential. For
this purpose, the T700 has a high-precision, quartz-accurate PLL speed control
via a contactless optical sensor. It corrects the deviations (e.g. caused by
ambient/temperature fluctuations, aging of belts and bearings, friction during
the scanning process) and ensures compliance with the absolute target speed
with a tolerance of 0.1%. In addition, the belt drive in, conjunction with a
high plate mass and an optimally designed plate bearing, already leads to
almost perfect synchronization. The soft start for a slow motor start-up
guarantees reduced belt wear.
Note on wearing parts
The mechanical and electrical design of the T700 turntable is aimed at
providing several years of use and enjoyment of music.
Owing to the principle, however, there are two components, namely the pick-up
system including the needle and the drive belt, which are subject to a certain
amount of wear and tear or aging and should be replaced if necessary. Revox
recommends replacing these two components either after 500-800 hours of
operation or 4-5 years, whichever comes first.
Assembly and installation
The STUDIOMASTER T700 turntable is a mechanical precision instrument and is therefore dismantled before transport so that the turntable bearings and tonearm bearings are not damaged during transport. Before dismantling, each T700 turntable is completely assembled, the shaft and bearings are aligned with one another and a complete final test is carried out. Acoustic monitoring of the T700 in a hi-fi chain concludes the test.
Note on turntable storage:
Should you, as a dealer or customer, set up several T700 turntables at the
same time, the turntable bearings of the individual package units may not be
interchanged. After the turntable bearings have been leveled in the factory,
the bushing, and axis match and form a mechanical unit.
Note on gloves
when you open the inner box of the T700 Turntable, you will find a pair of cotton gloves. These are included so that the T700 can be assembled without leaving fingerprints or scuff marks. It is particularly important to use cotton gloves when fitting the drive belt. Under no circumstances should it come into contact with grease or oil, otherwise adhesion to the pulley is no longer sufficient and the rubber belt ages prematurely. Should the belt come into contact with grease/oil, it can be cleaned with alcohol/isopropanol. Only insert it again when the belt is completely dry.
Note on temperature
Before starting with the assembly, the turntable and all of its components
should have reached room temperature. This is particularly important for
assembling the turntable bearing since low temperatures lead to different
expansion or contraction of the bushing and axle and the correct fit may not
be given.
Assembly step 1: Checking the DIP switches
Prior to installation, unless you want to install a different pick-up, you
should check the DIP switch position of the integrated phono preamplifier on
the underside of the chassis. This is set to factory-assembled Ortofon Quintet
Bronze MC system with a terminating resistor of 100 Ω and again for 300 µV
(0.3mV) output voltage. A detailed description of the integrated phono
preamplifier can be found in the chapter Phono preamplifier.
Fig: Factory setting phono preamplifier for Ortofon Quintet Bronze
Assembly step 2: Placing sub-platter and platter
In the next step, first, remove the plastic cover plug from the platter
bearing. Make sure that no sharp-edged objects are used that could damage the
soft sintered bronze bearing bush. The plug should be kept in the accessories
box for future transport.
Attention: There is a loose, polished steel ball in the bearing bush that can
fall out if you now turn the chassis through 180°!
The aluminum sub-platter and the POM platter are provided as a unit in the packaging. Release the sub-platter from the platter by applying slight pressure onto the steel axle. As a precaution, this should be done above a soft cushion so that the sub-platter cannot be damaged if it falls. After loosening, the sub-platter with the steel axle can be inserted into the socket. Due to the tight fit, the sub-platter or the axle slides very slowly into the bearing. The axle has already been treated with special oil in the factory before the running-in phase and does not require any further action – not even after years of operation. Now place the black platter onto the sub- platter.
Assembly step 3: Fitting the drive belt
You should wear the enclosed gloves to attach the drive belt so that no
grease/oil can get onto the belt. The easiest way to do this is to first place
the belt around the large platter with two hands and then encircle the pulley
(drive shaft motor) by means of a slight pull. For an even application of the
belt, turn the platter a few revolutions by hand
until the belt is in the middle of the pulley.
Assembly step 4: Mounting the tonearm weight on the tonearm
For assembly of the counterweight, it is advisable not to loosen the transport
lock, which is attached to the tonearm holder.
Take the tonearm weight from the accessories box and place it evenly onto the
thread of the tonearm. You can now “screw” the tonearm weight by turning it
clockwise by applying slight pressure. The tonearm weight does not have an
internal thread, but two inserted silicone rings that contribute to decoupling
from the tonearm. A little pressure is therefore necessary until the first
silicone ring “grips” the external thread of the tonearm.
Turn the tonearm weight until there is approx. 26 mm distance between the
tonearm weight and the tonearm bearing, see figure below. This distance
approximately corresponds to a bearing weight of 23 mN (2.3g) when the Ortofon
Quintet Bronze pick-up is mounted. This is also the recommended tracking force
for this system. A precise adjustment is carried out in a second step using
the digital tonearm scale included in the scope of delivery.
Now remove the transport lock on the tonearm mount.
Assembly step 5: Setting the tracking force with the digital scale
In the penultimate step, the recommended tracking force is precisely set with
the help of the digital tonearm scale. For the preassembled Ortofon Quintet
Bronze pick-up system, the tracking force should be 23 mN, which corresponds
to approximately 2.3g at an altitude of 0-2000 m. For the measurement, pull
the protective cover horizontally off the tonearm scale and place the scale on
the turntable (without record and without anti-skating weight).
Now the needle guard of the pick-up is removed. Switch the balance on with the button and lower the needle directly onto the center (marked point) of the balance using the tonearm lift. By means of the displayed value, you can now decide whether the tonearm weight has to be screwed closer to the tonearm bearing (value is less than 2.3g) or whether the tonearm weight has to be turned outwards (value is greater than 2.3g).
The tracking force of 2.3g recommended by Ortofon should serve as a reference
value and may be adjusted within a range of ± 0.2 g according to your own
preferences. The possible range provided for the tracking force of the Quintet
Bronze System by Ortofon itself is 2.1 – 2.5 g.
A detailed description of the Revox tonearm scale can be found in the Tonearm
scale chapter on page 12
Assembly step 6: Attaching the anti-skating weight
As an anti-skating device, the T700 has a weight that generates a
counterforce via a small pin on the tonearm bearing. This small weight is
located in the accessories box and is attached to the pen with a small thread
via a deflection unit. For the 5.0 g anti-skating weight (diameter 9 mm) is
recommended to use the middle groove in the pin. If you have the smaller 1.8 g
anti-skating weight (diameter 6 mm), the outer groove is recommended.
Note:
The determination of the tracking force (assembly step 5) must always be
carried out without the anti-skating weight, as otherwise measurement errors
may occur. With the help of the tonearm scales you can easily determine the
weight of your anti-skating weight.
Assembly Step 7: Connecting T700 turntable
In the last step, connect the T700 turntable to the power supply and the hi-fi
amplifier.
Power supply:
On the back of the T700 turntable is the input socket for the external power
supply, which is included in the scope of delivery.
Insert the barrel connector into the socket labeled DC Power. Only the power
supply unit supplied by Revox may be used.
Third-party power supplies can cause damage and malfunctions that are not
covered by the warranty.
Technical data power supply unit:
input 100-240 VAC / 50-60 Hz
output 12 – 15 VDC / minimum 1A
Audio connection:
The T700 has a very high quality MC phono amplifier, which is preconfigured
for the Ortofon Quintet Bronze pick-up system in the factory. At the output of
the cinch sockets Analog Line Output, the T700 outputs a stereo audio signal
at line level. This means that the T700 can be connected directly to any
analog input of an amplifier, receiver or an Audiobar from Revox without the
need for a separate phono preamplifier. These inputs are usually identified
with the names Line-IN, Analog Input, Aux, CD, Tuner, Tape.
Note: The T700 must not be connected to an MC or MM input of an
amplifier!
A separate ground line, as is usual with turntables without an integrated phono preamplifier, is not necessary with the STUDIOMASTER T700. Thanks to the amplified signal at line level, the risk of interference is no longer as critical as with turntables without a preamplifier. However, for audiophile reasons, Revox recommends using a high quality, well-shielded cinch cable. Specialist stores or retailers can provide good advice on this matter.
Operation
Testing after assembly
Before you put on the first record, you should carry out a test after
assembling the T700. Connect the T700 to the mains; the STOP button on the
glass surface lights up in red. The tonearm is in its holder and the needle
guard underneath the cartridge has been removed.
Now start the turntable at the low speed by touching the button on the
surface. Immediately the turntable begins to turn. As long as the target speed
of 33 ⅓ revolutions per minute has not yet been reached, the lighting under
the button pulsates.
Once the target speed is reached, the button lights up continuously.
For the sake of clarity, the button is only labeled with the number 33, but
the speed is of course regulated to precisely 33 ⅓.
In the next step, the higher speed of 45 revolutions per minute can be tested
by touching the button . Here too, the lighting under the button pulsates
until the target speed is reached.
In both cases, the target speed should be reached after 3-6 seconds. If the
time is longer, the speed control should be calibrated. This is done on the
back of the T700 using the two adjusting screws of the spindle trimmer next to
the power supply.
You will find a detailed explanation of this in the chapter on target speed
setting on page 10.
Finally, the horizontal level of the installation location for the T700 can be checked with the aid of the circular level included in the scope of delivery. The circular level (Fig. 2) is located in the accessories box and is simply placed on the surface that is to be tested. The air bubble should remain within range of the 1 ° mark.
Playing a record
After this test, you can now put on a record. Please note the specified speed
for which the record was pressed. As a rule, longplaying records with a
diameter of 30 cm require a speed of 33 ⅓ revolutions per minute, the smaller
single records, with a diameter of 7 inches (17.5 cm), require a speed of 45
revolutions per minute. The speed is often also referred to as the playback
speed. For some small 7 inch records you need a single adapter / puck (not
included) that reduces the large inner diameter of a single from 38.1 mm to 7
mm on the regular mandrel in the middle of the turntable. Alternatively, you
also get plastic clips that are clipped in and remain permanently attached to
the single.
A single adapter can be safely stored in the accessory box in the compartment
of the circular level.
An incorrectly selected speed does not cause any damage, neither to the
needle nor to the recorder, it is only manifested in a wrong pitch; keyword
“Mickey Mouse effect”
Note on the turntable platter
The turntable of the T700 is made of POM, a type of plastic which has a very
low resonance and can be specifically used without the turntable support. If
you are still a fan of turntable support, you can of course use one. For this
you should note that the height setting of the tonearm may then have to be
adjusted to the higher position of the record.
How this is done is described in the chapter Adjusting the tone arm height on
page 11.
Cleaning the record
Before starting playback, the record should first be cleaned with the
turntable brush. Dust on the record leads to crackling noises during playback
and can settle on the sensitive needle.
A turntable brush with carbon fibers is included with the T700 and is located
in the accessories box. Place the brush vertically on the rotating record, the
brush pointing towards the center of the record, similar to the second hand
on a clock. The brush remains on the record for a few seconds and is then
slowly pulled outwards. If necessary, repeat this process until no more dust
particles are visible on the record.
To clean the brush, the carbon fiber comb is simply swiveled over the bar in
the brush frame. Compressed air from the can (photo accessories) helps with
thorough cleaning of the brush.
Attention: Please do not use compressor air, it contains fine oil
components.
The carbon fibers should not be touched, in order to prevent a greasy film
that causes them to stick to each other.
Starting playback.
If the record is rotating at the correct speed, check whether the tonearm lift
is in the upper position. To do this, swivel the lift lever from the lower
position (Fig. left) to the upper position. The lift slides up to just below
the tonearm. Now you grasp the system carrier (also known as the headshell)
and pull the tonearm out of the tonearm holder to the left, over the lead-in
groove of the record. The lead-in groove is on the outside diameter. With the
lift lever you lower the tonearm and the music begins to play.
Stopping playback
The T700 does not have an automatic limit switch. When the record is finished,
the needle remains in the groove and the record player continues to turn until
the stop button is pressed. When the turntable is at rest, you raise the
tonearm again with the lift lever and then manually guide it back into the
tonearm holder . The tonearm lift may remain in the upper position, because if
it is correctly adjusted, it does not exert any pressure on the tonearm when
it is in the holder.
Caution
If there is no record playback, the tonearm should always be “parked” in its
holder.
A needle that remains in the groove for days or weeks can damage the needle
bearing and thus reduce the tracking ability.
The lead-out groove is near the center of the record
Basic settings and maintenance
Liability
The correct setting of the mechanical components of a T700 turntable requires
experience and know-how. Revox cannot accept any liability for damage caused
by personal handling. If in doubt, please always contact your specialist store
or retailer!
Phono preamplifier
The integrated phono preamplifier is designed for MC (Moving Coil) cartridges.
For these systems it can be adapted very precisely to the sensitivity (gain)
as well as to the recommended terminating resistor. Revox only uses gas-tight
DIP switches for configuration, which can be set with the help of a small
miniature screwdriver. Other switch systems, such as toggle switches or
relays, unlike DIP switches, cannot guarantee the required contact reliability
for years. The braid of the tonearm is directly soldered to the input of the
phono preamplifier by hand. This ensures that the audio signal, which is
sensitive to interference, reaches the phono preamplifier via the shortest
possible route.
The phono preamplifier is located on the underside of the T700 in the area of
the two cinch sockets. To set the DIP switches, the turntable including the
sub-platter should be removed for safety reasons when the T700 is placed on
its side. The tonearm should be in the tonearm mount.
Important All DIP switches must always be laterally reversed with the
same values. Only in so doing can the left and right audio channels behave
identically.
Terminating resistor (MC Loading)
The two 6-pin DIP switches can be used to adapt the terminating resistor to
the pick-up in the range of 47 – 2000 Ω. A selection of 6 completely low-noise
Susumu resistors are available, which can be used individually or
simultaneously. If only a single resistor is selected with the DIP switch,
i.e. the DIP switch is in the ON position, the printed value is the
terminating resistor. In the case of the Ortofon Quintet Bronze pick-up
system, Revox decided on a value of 100 Ω – see Figure 2.
Intermediate values can also be implemented by connecting 2 or more DIP
switches at the same time.
The general formula for this is:|
---|---
For two DIP switches the formula is:|
Example: DIP switches 100 Ω and 470 Ω are in the ON position, resulting in a terminating resistance of approx. 82 Ω
The smallest terminating resistance is achieved when all 6 DIP switches are in
the ON position. This results in a value of approx.
25.3 Ω. The highest terminating resistance of 2000 Ω is available if only DIP
switch 2000 Ω is in the ON position.
Sensitivity (MC Sensitivity)
The phono amplifier can be adapted to different sensitivities of MC systems.
There are 4 levels for output voltages of 150 µV, 300 µV, 600 µV and 1200 µV
to choose from. The gain of the phono preamplifier and thus the output
voltage of the audio signal are set via the sensitivity. The equalization
takes place according to the RIAA characteristic (Recording Industry
Association of America).
Attention: DIP switch
Contrary to the selection of terminating resistors, only 1 DIP switch may be
in the ON position when setting the sensitivity.
A mixture of different sensitivities is not permitted.
The phono preamplifier is set to the Ortofon system Quintet Bronze in the factory, which provides an output voltage of 300 µV (0.3 mV at 1000 Hz, 5 cm / sec.) – see figure on the right.
Fig.: Factory setting for sensitivity
Target speed setting
The tonearm of the STUDIOMASTER T700 turntable is set in the factory to the
pre-assembled Ortofon Quintet Bronze pick-up system. This includes the
parallel alignment of the tonearm to the turntable, the setting to the two
angle-neutral fixed points and the azimuth alignment of the pick-up.
Furthermore, the PLL circuit, which is implemented via optical scanning below
the turntable, is set to the target speeds of 33 ⅓ and 45.
Over the years, it may be necessary to readjust the target speed due to wear
and tear and aging. This can be seen if it takes more than approx. 3 -6
seconds to reach the target speed after starting. The calibration is carried
out separately for each of the two target speeds. All you need for calibration
is a miniature / watchmaker’s screwdriver that is 2.5mm wide. The setting is
carried out on the back of the T700 in the Speed Calibration area.
Calibration of target speed
Start the calibration procedure for 33 ⅓ revolutions per minute by pressing
down on the two touch buttons and at the same time for about 5 seconds. The
two buttons will now start pulsating. Now take the miniature screwdriver and
turn the spindle trimmer on the back of the T700 in one direction and watch
the pulsating button for a moment. The result is only achieved after 2-4
seconds! If the button pulsates faster, you have moved further away from the
target speed and have to turn in the other direction. The minimum deviation
from the target speed is reached when the button lights up continuously. You
can now conclude the calibration by pressing the stop button .
In the second step, proceed in the same way with the target speed of 45 revolutions per minute by pressing down on the two touch buttons and at the same time for approx. 5 seconds.
Replacing the pick-up
The pick-up system should be exchanged after 500-800 hours of operation. If an
Ortofon Quintet Bronze is used once again as a replacement, the alteration is
very easy. The needle guard should be put on for removal. First, the 4
connecting wires are removed from the cartridge using tweezers. Then the two
screws in the system carrier are loosened with the included Allen key SW 2.0
until the pick-up can be removed. To assemble the new system, proceed in
reverse order. For a system change with different mechanical dimensions,
readjustment of zero crossing, tonearm height, anti-skating, and tracking
force is necessary. With the screw (Torx TX10 or Allen key SW 2.0) the pick-
up can be set to the correct zero crossing. A tonearm adjustment template is
required for this, e.g. from Schön, Ortofon, or similar.
Adjusting the height of the tonearm
The height of the tonearm of the T700 can be adjusted. This can be necessary
if e.g. a different cartridge is installed or when turntable support is used.
In the delivery condition, the tonearm is already correctly set to the Ortofon
Quintet Bronze and does not require any adjustment. Provided that the record
is placed directly on the black turntable without the turntable support.
The height of the tonearm is changed by loosening the two hexagon socket screws on the tonearm base and by changing the height of the tonearm tube vertically. A 3.0 wrench is required for the two Allen screws. You can find this as an accessory in the accessories box; it is the largest of the Allen keys.
A correct height is reached when the tonearm is parallel to the record when it is lowered. With two small blocks, e.g. with Lego or Fischertechnik building blocks which are placed on an old record below the tonearm, you can quickly and easily determine the parallelism. The further the blocks are placed from one another, the more precisely one is able to recognize a non-parallel alignment. After the correct tonearm height has been determined, the two Allen screws SW3.0 have tightened again with light force.
Setting the azimuth of the stylus
The azimuth describes the angle that is formed by the stylus of the pick-up
system and the record when viewed from the front.
It should be exactly 90 degrees to the groove/record. When the T700 is
shipped, the azimuth is already correctly set to 90 °.
The azimuth is set by turning the system support (headshell) in the tonearm
tube. To do this, the small cylinder screw must be loosened using an Allen
key SW 1.5 – see figure below
The azimuth is set correctly when the pick-up system/stylus is exactly perpendicular to the turntable surface. With the Ortofon Quintet Bronze pick- up system, the azimuth can be very accurately determined with the help of a small make-up mirror that is placed under the pick-up. Viewed from the front, every small difference/misalignment in the horizontal plane can then be clearly identified. Carefully tighten the small screw again by hand after the adjustment process.
Tonearm scale
Revox delivers the T700 with a digital tonearm scale in the accessory box for
precise determination of the tracking force. This allows you to set the
tracking force recommended by the manufacturer of the cartridge to an accuracy
of 0.01 g. A test weight of 5.0 g is included in the accessories box for
checking the measurement accuracy.
The scale plate is very sensitive and therefore has a protective cover that
can be pulled off to the right. The protective cover should be used when the
balance is not in use.
The tonearm scale has 3 buttons with the following functions:
M Measurement
Switching between different units of measurement.
Power
Switches the tonearm scale on and off. There is an automatic switch-off
function after approx. 120 seconds.
T Tare
This key can be used to perform a zero adjustment. To do this, the scales must
be placed on a flat, horizontal surface. If the tare key is pressed and held,
the currently measured weight is classified as a value of 0. After resetting
the supplied test weight, the tonearm scale should show a value of 4.98 – 5.02
g.
Calibration
Calibration should only be carried out if there are problems with determining
the tracking force or the enclosed test weight of 5.00 g is not displayed
correctly.
Procedure: Switch on the scale with the power button and wait until the scale
shows 0.00 g. Now press and hold the power button
until the display shows – 0 -. Wait until the displays flash the required test
weight of 5.00 g. Now place the enclosed 5 g test weight on the scale. The
display now shows 5.00 g continuously and ends the calibration process with
the display PASS. If you now remove the test weight, 0.00g appears. The
calibration is complete.
