STUDIO
MASTER T700 Turntable

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 a gain for
300 µV
(0.3mV) output voltage. A detailed description of the integrated phono
preamplifier can be found in the chapter
Phono preamplifier
.
