Parasound Zpre2 - Troubleshooting Common Issues; No Sound Problems; Remote Control Malfunctions; Audio Interference and Hum

ARE YOU HAVING DIFFICULTY?
No sound
- Check that AC is live.
- Check that input and output cables are secure at both ends.
- Make sure it is switched to the correct input.
- Is the unit on? Check setting of the Auto-Man switch.
Remote does not operate
- Zpre2 won’t respond to the remote control. Press remote’s Zone button then remote’s 1 button.
- Weak or dead batteries in remote. Replace batteries and please recycle old ones.
- IR Interference. Insure that the front panel IR receiver is not obscured or exposed
to direct sunlight or to an LCD or a plasma TV screen.
- If you can not select an input other than Input 1, turn off the Priority auto select feature by
holding the Preamp In 1 button down for 4 seconds (see page 8).
- IR zone code setting does not match the unit. Change zone numbers so they match.
- Incorrect remote. Must be Parasound PTZ-1 or using IR codes corresponding to PTZ-1.
Background Hum
- Move audio cables and AC cords away from each other.
- Try different routes for the audio cables and AC cords.
- Make sure insulating shoulder washers are used if unit is rack mounted.
- Try reversing the direction of the AC plugs in other components, one by one.
Distorted and Weak Sound
- Make sure the gain of the power amp is not set too low.
- Are you trying to use Zpre2 with a turntable? It does not have a built-in phono preamplifier
stage. You will need a phono preamp such as the matching Parasound Zphono.
