This FAQ guide explains the Pioneer DDJ-SX microphone input options and how to connect a microphone correctly. 

The Pioneer DDJ-SX has two microphone input options. 

Mic Input 1 (channel 3)

• Input switch on front of unit must be switched to MIC. 
• Either an XLR connector or a phono mic plug (1/4"/TRS) cable can be used.

Mic Input 2 (channel 4)

• Input switch on front of unit must be switched to MIC.
• A (1/4"/TRS) cable can be used.

NOTE: Connecting your Microphone while the DDJ-SX is powered on can cause unwanted noise / distortion. Before you connect your microphone make sure the "channel gain knob" and "channel fader" are set to ZERO. This will stop loud unwanted noises / distortion going to your speakers while you connect your Microphone.

Troubleshooting.

"My Microphone Input Sounds Distorted, what should I do?"

1. Check the impedance level for your microphone.

• The standard input level/ input impedance for the DDJ-SX mic is "-52dBu/10kΩ."
• Does your mic match the impedance level required by the Pioneer DDJ-SX? 

If the impedance levels don't match you can purchase a microphone attenuator. 

• This lowers / increases the microphone impedance level to suit the DDJ-SX Mic input level.
• Plug this device into the end of your Mic XLR cable before it's plugged into the DDJ-SX unit.

2. Are you using a wireless microphone? 

• Does the wireless microphone have a gain switch / gain adjustment knob? 
• Lower the wireless microphone gain output knob. 

Note: The Pioneer DDJ-SX does not support LINE output wireless microphones. We recommend you use a wireless microphone which has a switch for selecting LINE/MIC output options. Always use the MIC output option when connected to a Pioneer DDJ-SX.
