Problem Sound of a computer cannot be output from this unit. Check Are this unit and computer properly connected? Are the audio output device settings properly set? Is the input selector switch set to the proper position? 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 Connect this unit and the computer directly using the included USB cable. (page 6) Select this unit with the audio output device settings. For instructions on making settings for your application, see your application's operating instructions. Set the input selector switch to the [USB */*] position. (Page 12) For [ECHO], [SPIRAL], [REVERB], [ROLL], [SLIP ROLL], [REV ROLL] and [VINYL BRAKE], when the effect is off, 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 5) 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 5) If the analog player has a PHONO/LINE selector switch, switch it to PHONO.
