Input Button
Press the Input button to select the desired input. There are three inputs, Phono, Line 1 and
Line 2. This will change both the analog Line Out and the digital USB Out to the selected input.
USB Clip Indicator
USB Clip will flash red when the input level to the analog to digital (A-D) converter for the USB is
overdriven. If USB Clip illuminates while you are recording to your computer the recording will
sound very distorted. When the USB gain is set correctly USB Clip should not light at all, or flash
very infrequently only for the loudest musical peaks. Instructions for correctly setting the USB
gain are on page 11. Please note that the USB Clip indicator is only active when you have
connected the Zphono•USB to a computer using the included USB cable.
USB Gain Adjustment Knob
The USB Gain control sets the volume level for the USB output. It has no effect on the analog
Line outputs. In order to get the best recording quality it is very important to properly set the USB
Gain every time you record an album. Instructions for setting the correct USB gain are in the
following section.
Once the USB Gain is set for a particular album it should not be touched again
until recording for that album is finished.
