Pioneer DJM-850 Operation Manual - Page 26

Problem Check Effect sound cannot be monitored - even when the [CUE] button for [BEAT EFFECTS] is pressed. Sound is distorted when an analog player is connected to this unit's [PHONO] terminals. Or, lighting of the channel level indicator does not change even when the [TRIM] control is turned. Have you connected an analog player with a builtin phono equalizer? Is an audio interface for computers connected between the analog player and this unit? Remedy The circuit generating the [ECHO], [UP ECHO], [SPIRAL], [REVERB], [ROLL], [SLIP ROLL] and [REV ROLL] echo sounds is positioned after the effect circuit, so the effect sound cannot be monitored. This is not a malfunction. For analog players with built-in phono equalizers, connect the player to the [CD/ LINE] or [LINE] terminals. (page 8) If the analog player with built-in phono equalizer has a PHONO/LINE selector switch, switch it to PHONO. If the audio interface for computers has a line level output, connect it to the [CD/ LINE] or [LINE] terminal. (page 8) If the analog player has a PHONO/LINE selector switch, switch it to PHONO. 26 En
