Is the external effecter's audio output level set appropriately? Adjust the external effecter's audio output level.

There are three possible causes.

1. If the audio input level is too high or too low, the BPM value may not be correctly measured. Adjust the [TRIM] knob so that the channel level indicator lights up to around [0 dB] at the input sound's peak level.
2. Depending on the track, the BPM value may not be correctly measured. In this case, use the [TAP] button to input the BPM value manually.

The values may differ slightly due to different methods used for measuring the BPM. This is not a malfunction.

There are six possible causes.

1. Is the [USB, LINE, PHONO] selector switch set to the proper position?
Turn the [USB, LINE, PHONO] selector switch and set it to the channel's input source.
2. Are connection cables properly connected? Connect the connection cables properly. For details, see "Connecting input terminals" and "Connecting output terminals" in the operating instructions.
3. Is [MASTER LEVEL] set to the proper position? Adjust [MASTER LEVEL] so that the master level indicator lights up to the orange indicator at the peak level.
4. Is [TRIM] set to the proper position? Adjust [TRIM] so that the channel level indicator lights up to the orange indicator at the peak level.
5. Are terminals and plugs dirty? Wipe any dirt off terminals and plugs before connecting.
6. Is [MASTER ATT.] set at for example [-12 dB]? Switch [MASTER ATT.] at the [UTILITY] screen. For details, see "Changing the settings" in the operating instructions.

There are two possible causes.

1. Is [MASTER LEVEL] set to the proper position? Adjust [MASTER LEVEL] so that the master level indicator lights up to the orange indicator at the peak level.
2. Is [TRIM] set to the proper position? Adjust [TRIM] so that the channel level indicator lights up to the orange indicator at the peak level.

If the sound is distorted even after the input/output level has been adjusted, the level may exceed the power amplifier's maximum allowable input level. Set an appropriate level using [MASTER　OUT][ ATT] at the Setting Utility . The level can be attenuated by 25% at -12dB, by 50% at -6 dB. This setting does not affect the master level indicator.

There are two possible causes.

1. Is an analog player with an internal phono equalizer connected? When using an analog player with an internal phono equalizer, connect it to the [LINE] terminals.

2. Is a computer sound card (audio interface) connected between the analog player and this unit? If the computer sound card's output has a line level, connect to the [LINE] terminals. For details, see "Connecting input terminals" in the operating instructions. If the analog player is equipped with a PHONO/LINE selector switch, switch it to PHONO.
