Pioneer DJM-850-W Operating Instructions Manual page 25

Problem
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.
Check
—
Have you connected an analog player with a built-
in 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 7)
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 7)
If the analog player has a PHONO/LINE selector switch, switch it to PHONO.
