I am selling my Pioneer DJM-400 DJ mixer, which I have used at home for many years. I used it almost every day, and there are no problems with sound output or normal operation. There is no crackling, and the faders and EQ are smooth. However, due to the following defects, I will sell it as junk: • The effect selection switch is broken, and the effect function cannot be used (photo 8) • The effect buttons sometimes blink on and off spontaneously • The MIC EQ knob is missing, and the MIC 2 LEVEL adjustment knob is cracked and missing (photo 9) * Power-on and sound output have been confirmed. It can be used without problems for normal 2-channel mixing. * Recommended for repair, parts replacement, or as a custom base. I only used it indoors and in a non-smoking environment, so the condition of the housing is relatively good. I am selling it because I am replacing my equipment. Please note that this is a junk item, so no returns or refunds will be accepted. The items for sale are the DJ mixer itself and the power cable only. The original box and instruction manual are not included. When shipping, I will wrap it in bubble wrap (protective material) and pack it securely. - Model name: DJM-400 - Number of channels: 2 channels - Function: BEAT EFFECTS - Headphone output: With headphone output - EQ: LOW, MID, HIGH - Master output: With master output level adjustment
