A Message From the President 

 
Thank you for choosing the Magnum Dynalab “

MD 90T

” FM Tuner. Great care 

has been given in the design, manufacturing and selection of components for the 

MD 90T” 

FM Tuner. This complete process will insure that your listening 

experience will be optimized for years.  
 
The front end of all Magnum Dynalab tuners is an exclusive “in house” designed 
and manufactured component, we are the only company in the world that does 
their own R.F. “Front-end”. The reason that we design and build our own front-end 
is that no other manufacturer can make one that meets our exacting 
specifications. The importance of a front-end to the tuner is the equivalent of a 
high performance laser mechanism to a CD transport. The front-end must gather 
the FM signal and isolate it from the extraneous aberrations inherent in the 
environment as well as the FM stations adjacent to it. Our rigid criteria for our 
tuners and their front-ends insure that you get the most out of your FM reception 
with the highest degree of consistency available in the industry.  
 
To insure that all specifications on our tuners are met at ALL frequencies, we 
manually align our tuners front-end at three frequencies (92 MHz, 101.5 MHz 
and 106MHz). This process optimizes tuning performance across the entire FM 
band, so that you attain the same levels of quality regardless of where you are 
tuned. 
 
These procedures also ensure that the balance between SENSITIVITY, 
SELECTIVITY and MUSICALITY are maintained. Your tuner is now optimized to 
reject strong adjacent channel noise, provide more consistent levels of tuning 
performance across FM band and to have a superior ability to isolate the station 
you wish to listen to from the extraneous interference of the FM signals. 
 
Once again MAGNUM DYNALAB thanks you for including our product in your 
audio system, we are sure that you will have years of listening pleasure from your 

MD 90T

”. If there is anything else we can offer to aid your enjoyment in listening 

to FM, please feel free to contact us on our toll free number, 1-800-551-4130 
or via email at: [email protected]
 
 
Respectfully yours,  
Larry Zurowski 
 
 
 
President
