SETTING UP YOUR MD 90 

 
1.

 

Place your tuner the shortest distance possible from your pre-amplifier/ 
integrated amplifier, being careful to avoid areas that may cause extreme 
temperatures.  
 

2.

 

Connect your tuner to the pre-amplifier, using cables/ inter-connects that are 
consistent with the rest of the inter-connects in your system. For a single 
ended (un-balanced) system the cables will be connected to the RCA 
connectors labeled “unbalanced out” on the rear panel of your tuner to an 
unused aux. input on the rear of your pre-amplifier/ integrated amplifier. For 
connection to a balanced system, the balanced cables will be connected from 
the XLR outputs marked “output balanced” on the rear of your tuner to the 
balanced inputs on the rear of your pre-amplifier/ integrated amplifier.  
 

3.

 

Connect your FM antenna cable to the 

ANTENNA IN 

terminal on the rear 

panel of your tuner. The connection type on the back of your tuner is an “F” 
connector (75 ohms). Should your antenna cable be 300 twin lead, you may 
convert this to 75 ohms with a 300 ohm to 75 ohm balun/ transformer.  

 
4.

 

Make sure that the center conductor of the cable is properly inserted into the 
connector. If you do not possess an antenna, attach the 

temporary

 wire 

(enclosed in box) to your tuner. Place this into the “F” connector input on the 
rear of your tuner. 

 

Please note that the piece of wire provided should only be used as a medium 
to test and setup the tuner, to maximize performance with your tuner a better 
antenna system is recommended. Magnum Dynalab offers a number of 
different antennae, these antennae are discussed in the 

Reception Techniques

 

in the back of the manual. If you have any questions please call your dealer or 
contact Magnum Dynalab directly. 

  

 

5.

 

Unwrap the EIA AC cord and plug the EIA end into the rear socket marked 
“Power Input” on the rear panel of your tuner. Plug the other end of the AC 
cord into a 120/220/230/240 volt continuous AC source that you are 
using.  
 

Note: Many countries that use 220/230/240 volts have a special FM 
transmitter, tuning de-emphasis for these countries may be different. Please 
consult Magnum Dynalab for the correct usage. If your tuner is used in a 
country where the tuning de-emphasis is set incorrectly the sonic performance 
will be seriously affected.
