Cartridge Settings  
 

MC & MM Gain Options 

Before listening to the Zphono XRM you should select the appropriate gain for your cartridge.  
The most typical settings are 40

 

dB for MM and 60

 

dB for MC.  This is a good place to start but 

you may want to experiment to see what sounds best in your system.  

We suggest turning off 

the Zphono XRM before making gain changes to prevent an audible “pop” noise. 

 
 

MC Gain Options: 

50

 

dB   

For high output moving coil cartridges. 

60

 

dB   

For low output moving coil cartridges whose output is less than 0.5

 

mV.

 

  

MM Gain Options: 

40

 

dB   

Appropriate for most moving magnet cartridges.

 

50

 

dB   

For low output moving magnet cartridges.

 

 
 

 
 

MC Input Impedance Adjustment

 

The Zphono XRM’s Impedance adjust knob allows you to fine tune the input impedance for MC 
cartridges over a range of 50 ohms to 1050 ohms.  Cartridge manufacturers recommend what 
they consider to be an optimal load impedance. However, their published specification won’t 
necessarily give you the best results in your system.  We encourage you to experiment with this 
control and use whichever load impedance you feel results in the best performance of your 
system.  
 
 
 

Audio Output Connections 

The Zphono XRM Output jacks connect to the line level input jacks on your line stage 
preamplifier, integrated amplifier or receiver.  Both balanced XLR and unbalanced RCA output 
jacks are provided.  If your preamplifier, integrated amp or receiver is equipped with balanced 
XLR inputs we recommend using the Zphono XRM Balanced XLR output jacks for the maximum 
rejection of external noise. The balanced and unbalanced jacks are active simultaneously.
