Connecting your Zphono•USB
Always disconnect the AC cords to your Zphono•USB and power amplifier(s) before
making or changing any input, output or trigger wire connections.
Inserting or removing an
input or output cable while the Zphono•USB or power amplifiers 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. The Zphono•USB has a few connectors with
which you might not be familiar. Please read this section thoroughly before making
connections.
Audio Input Connections
Phono Input Jacks and GND
Connect your turntable’s signal cables to the Phono Input jacks on the Zphono•USB. The
Phono Input jacks should only be used with a record player. Any other source such as a tuner
or CD player should be plugged into the Line 1 or Line 2 Input jacks. The turntable’s ground
wire attaches to the GND (Ground) terminal.
Choose the Correct Cartridge Setting
The Cartridge Switch has 3 settings to select the gain/loading for the type of cartridge you are
using. There are three positions for the cartridge switch: MC-100
Ω ,
MC-47k
Ω and
MM-47k
Ω .
Choose the setting that best matches your cartridge type:
 The MC-100
Ω
setting is for most moving coil (MC) cartridges. It provides the higher gain
required for MC cartridges and a 100 ohm load that is recommended for most MC
cartridges.

The MC- 47k
Ω
setting provides appropriate gain for MC cartridges and a 47k ohm load
that you might prefer for your MC cartridge. You can try the MC-100
Ω
or MC-47k
Ω
to
see which setting sounds better in your system.

The MC- 47k
Ω
setting is also appropriate for moving iron (MI) cartridges such as Grados.
 The MM- 47k
Ω
setting is for all moving magnet cartridges. It provides appropriate gain
for MM cartridges and a 47k ohm load that is recommended for most MM cartridges.

Some very high output MC cartridges will sound better with the MM- 47k
Ω
setting.
If you are unsure which setting is best for your cartridge we recommend that you contact your
dealer or the manufacturer of your cartridge. You can also experiment and simply use the
setting which sounds best in your system. The majority of turntables use MM type cartridges
so start with this setting first.
