TROUBLESHOOTING TROUBLESHOOTING Incorrect operations are often mistaken for trouble and malfunctions. If you think there is something wrong with this component, check the points below. Sometimes the trouble may originate from another component. Thus, also check the other electrical appliances also in use. If the trouble cannot be rectified even after checking the following items, contact your dealer or nearest PIONEER service center. Symptom No power No sound, or sound volume is too low. Microphone sound isn't produced in BOOTH output. No digital output. Sound is distorted. Cross fader doesn't work. Can't perform fader start with CD player. Effects don't work. External effector doesn't work. Sound from external effector is distorted. BPM can't be measured. Measured BPM value is incorrect. The measured BPM value is different from the value published with the CD. MIDI sequencer can't be synchronized. Possible Cause ÷ The power cord has not been connected. ÷ Input selector is set incorrectly. ÷ The rear panel's DIGITAL/CD input selector switch or DIGITAL/LINE input selector switch is set incorrectly. ÷ Connection cables are connected incorrectly, or connections are loose. ÷ Jacks or plugs are dirty. ÷ The rear panel master output attenuator switch (MASTER ATT) is set to -12 dB, etc. ÷ The rear panel's MIC SIGNAL switch is set to [CUT]. ÷ The digital output sampling frequency (fs) does not match the specifications of the connected component. ÷ Master output level is too high. ÷ Input level is too high. ÷ CROSS FADER ASSIGN switch setting ([A], [THRU], [B]) is incorrect. ÷ The FADER START button is set to OFF. ÷ Rear panel CONTROL jack is not connected to CD player. ÷ Only the rear panel CONTROL jack is connected to the CD player. ÷ Effect channel selecter setting is incorrect. ÷ Effect parameter 2 adjust dial (LEVEL/ DEPTH) is set to [MIN]. ÷ Effect selecter is not set to [SND/RTN]. ÷ Effector is not connected to rear panel SEND/RETURN connector. ÷ Effect channel selector is set to incorrectly. ÷ Input level from external effector is set too high. ÷ Input level is too high, or too low. ÷ BPM may not be correctly measurable with some tracks. ÷ Some differences may occur due to differences in BPM detection methods. ÷ MIDI sequencer's synch mode is not set to "slave". ÷ MIDI sequencer is not supported type. Remedy ÷ Connect to power outlet. ÷ Set input selector to playback component. ÷ Set the rear panel's DIGITAL/CD input selector switch or DIGITAL/LINE input selector switch to match the component being played. ÷ Connect correctly. ÷ Clean soiled jacks/plugs before connecting. ÷ Adjust rear panel master attenuator switch (MASTER ATT). ÷ Set rear panel's MIC SIGNAL switch to [ADD]. ÷ Set rear panel sampling frequency selector to match the specifications of the connected component. ÷ Adjust master output level (MASTER LEVEL) dial or the rear panel master output attenuator (MASTER ATT) switch. ÷ Adjust the TRIM dial so that the input level approaches 0 dB on the channel level indicator. ÷ Correctly set the CROSS FADER ASSIGN switch for the desired channel. ÷ Set the FADER START button to ON. ÷ Use a control cable to connect the CONTROL jacks of mixer and CD player. ÷ Connect both the CONTROL jacks and analog input connectors. ÷ Correctly select the channel on which you wish to apply effects. ÷ Adjust the effect parameter 2 adjust dial (LEVEL/DEPTH). ÷ Set effect selector to [SND/RTN]. ÷ Connect effector to the rear panel SEND/ RETURN connectors. ÷ Use the effect channel selector to select the audio source to which you wish to apply the effects. ÷ Lower the output level of the external effector. ÷ Adjust the TRIM dial so that the input level approaches 0 dB in the channel level indicator. ÷ Adjust other channels as well so that the input levels approach 0 dB in the channel level indicator. ÷ Strike the TAP button to set BPM manually. ÷ No remedy is necessary. ÷ Set MIDI sequencer's sync mode to "slave". ÷ MIDI sequencers that do not support MIDI timing lock cannot be synchronized. Static electricity or other external interference may cause the unit to malfunction. To restore normal operation, turn the power off and then on again. 22
