Line 1 and Line 2 Input Jacks
Connect the audio output jacks of line level sources such as a CD player, tuner or other audio
device to one pair of the Zphono•USB Line Input jacks. These are included so you can
conveniently record sources other than a turntable to your PC. The line inputs are not affected
by the settings of the Cartridge switch or the RIAA switch.
Audio Output Connections
There are 2 audio outputs on the rear panel of the Zphono•USB, one is a standard analog audio
output and one is a digital USB output for recording to your computer.
Line Out Jacks (Analog)
The Line Out jacks are for connecting your Zphono•USB to your stereo system. The L and R
Analog Out jacks carry the analog audio signal at a fixed level that is comparable to the analog
output level on a typical CD player or tape deck. The Line Out jacks are not affected by the
RIAA switch.
USB Out Connector (Digital)
The USB Out connection is used to record music to your computer. Use the included USB
cable and connect the USB Out to one of the free USB connections on your computer. This
cable is a standard computer cable. If you need a longer cable you can find one in any store
that sells computers. The audio level of the USB Output is determined by the USB Gain control
located on the front panel. See the USB Gain instructions on page 11
for information on how to
correctly set the USB Gain. The RIAA EQ can be turned on and off for the USB output. A
further explanation of the RIAA EQ is on page 8.
Other Connections
GND (Ground) Connector
The ground wire of your turntable should be connected to the GND connector. If it is not
connected you will most likely hear a loud hum in your speakers.
AC Line Cord
Connect the AC cord only after you have connected all of the other wires. The power cord
supplied with your Zphono•USB is an IEC standard AC cord. If possible, plug your Zphono•USB
into the same AC outlet into which your accompanying audio components (particularly your
preamp and power amplifiers) are plugged. If different AC outlets are used the ground potential
may be higher or lower between the outlets, resulting in audible hum in the speakers.
