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.
