How to fix a Pioneer DJm-909 Music Mixer that does not turn on?
If your Pioneer Music Mixer does not turn on, the power cord may not be properly connected. Ensure that the cord is securely connected to a power outlet.
Why can't the BPM be measured correctly on my Pioneer Music Mixer?
If the BPM cannot be measured or the value is strange on your Pioneer Music Mixer, it could be due to several reasons. The input level might be too high or too low; adjust the TRIM dial to set the input level around 0 dB on the peak level meter. BPM measurement may also be inaccurate with certain tracks, so set other channels so that the input level is around 0 dB. You can also manually strike the TAP switch to count BPM.
What to do if the effects don't work on my Pioneer DJm-909 Music Mixer?
If the effects are not working on your Pioneer Music Mixer, check the EFFECT switch. If the hand is released when the switch is in the [ON] position, it will return to [OFF]. Either hold the EFFECT switch at the [ON] position, or set it to [LOCK ON]. Also, ensure that the effect MIX/DEPTH dial is properly adjusted and not set to [MIN].
Why is my external effector not working with my Pioneer DJm-909?
If the external effector isn’t working with your Pioneer Music Mixer, make sure that the top panel’s SEND buttons (MIC SEND, CH-1 SEND, CH-2 SEND) are turned on for the corresponding channel you wish to apply effects to; the indicator light should be on. Also, verify that the external effector’s output coupler is connected to the RETURN jacks.
How to troubleshoot a CD player fader that won't start with my Pioneer Music Mixer?
If your CD player's fader won’t start with your Pioneer Music Mixer, ensure the top panel’s FADER START button is set to On. Additionally, check that the rear panel’s PLAYER CONTROL jack is properly connected using the control cord between the unit and the CD player.
