Sound is distorted | Only plug turntables into this input, do not plug in CD | |
players or other Line Level sources. Turn down the | ||
Phono Input | ||
INPUT GAIN CONTROL. Check the EQ settings. | ||

| Make sure you are using good shielded audio cables. | |
| Some less expensive audio cables can be susceptible to | |
| hum and interference. Keep your audio cables away | |
I hear hum. | from AC power cables and AC transformers. Make sure | |
the mixer is not mounted too close to high power ampli- | ||
| ||
| fiers or lighting equipment power supplies or ballasts. | |
| Make sure your turntables are properly grounded to the | |
| back of the mixer if they include a grounding wire. | |
|
| |
| If you are using a microphone, make sure that you are | |
| not too close to the speakers or headphones. If you hear | |
I hear | feedback on the phono input, then the turntable may be | |
mounted to close to the speakers and/or subwoofer. | ||

Also, make sure the turntable base is placed on a sur- | ||
