Connecting & Adjusting your Zphono XRM
Always disconnect your Zphono XRM’s AC cord and line stage preamp or integrated amplifier AC
cords before making or changing the input or output connections. Inserting or removing turntable
cables or output interconnects while the Zphono XRM and your integrated, line stage preamp or
receiver are turned on can result in a blast of sound that can damage your loudspeakers. Make
sure there is no strain or tension on any cables that could cause them to pull loose.
Turntable Connections
The Zphono XRM has separate input jacks and circuitry for MM (moving magnet) and MC
(moving coil) cartridges. Connect your turntable’s signal cables to the Input jacks on the Zphono
XRM that correspond to the type of cartridge you are using. You can connect two turntables
simultaneously if one turntable has an MC cartridge and the other turntable has an MM cartridge.
You can also use a turntable with two tonearms provided one is equipped with an MC cartridge
and the other with an MM cartridge. If you are unsure what type of cartridge you have then start
with MM since it is the most common.
Use the MM Input jacks if your cartridge type is MM.
Use the MC Input jacks if your cartridge type is MC.
Ground Connection
The turntable’s ground wire attaches to the Zphono XRM Ground terminal at the left side of the
rear panel. If you are using two turntables or a single turntable with two tonearms connect both of
their ground wires to this ground connection.
Note: In some systems eliminating hum or buzz might require connecting your turntable ground
wire directly to your integrated amplifier or preamp instead of to the Zphono XRM. You can use a
chassis screw or the outer ring of an RCA connector. In rare instances hum might be lowest if
your turntable ground wire is not attached at all.
Important Note: Turntables and phono preamps are very sensitive to electromagnetic fields that
can cause audible hum. To minimize hum follow these guidelines:
 Place your turntable(s) as far as possible from amplifiers and AC power
line conditioners.
 Run your turntable signal cables as far as possible from power amplifiers
and AC power line conditioners.
 Do not route the turntable signal cables parallel with any AC cords.
 Wherever turntable signal cords must cross AC wires they should cross at
a 90
o
right angle.
 It might be necessary for you to experiment with the exact positioning of
the turntable signal cables to minimize hum.
