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 (

ecording 

I

ndustry 

A

ssociation of 

A

merica).  

 
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.

Target speed setting  

The tonearm of the 

STUDIO

MASTER 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.
