A maximum of four DN-SC2900 units can be connected.• Before starting, use “Utility” – “Preset Setting” – “Network ID”(vpage 44) to set the Network IDs.Set “Utility” – “Preset Setting” – “Relay” (vpage 45)to “ON”.The mode switches to relay playback.• In relay playback, tracks are played in the following order.• If relay playback mode is off for a unit, tracks are not played.• If a “Network ID” number is missing, the number is skipped forplayback.“Network ID” : 1 “Network ID” : 2“Network ID” : 4 “Network ID” : 3• When “OFF” is selected in “Utility” – “Preset Setting” – “Relay”(vpage 45), normal playback is resumed.• If relay playback mode is set to ON during playback, relay playbackstarts from the next track.n About the track playback orderDepending on the playback mode, the track playback order differs.For details, see “Setting playback mode” (vpage 26).In SINGLE playback modeWhen playback of the track ends, playback of the next track starts onthe player registered with the next “Network ID”.In CONTINUOUS playback modeWhen playback of the last track ends, playback of the first track startson the player registered with the next “Network ID”.Network playback operationsAutomatically adjusting BPMWhen multiple DN-SC2900 units, are connected on the network, theBPM value from the desired player (MASTER) is set as the BPM on allother players (Slave) (BPM SYNC function).n Set as “Master”This sets the device that will be the standard when adjusting theBPM value.Press and hold BPM SYNC on the device that you wantto be “MASTER”.• “SYNC Master” appears on the display.• BPM SYNC flashes, and the “Master” setting is complete.• When the “Master” is set, all other connected players are set as“Slave”.• If another player is already set as “Master”, set the other players to“Slave” before setting the desired unit to “Master”.n Setting the “Master” BPM to the “Slave” BPMPress BPM SYNC on the unit set as “Slave”.• “BPM-SYNC” is shown in the display, and the BPM is set to the“Master” BPM.• The PITCH indicator flashes, and the pitch value is shown in thedisplay.• Pitch adjustment is locked.• When the pitch value at which the pitch slider is locked is matched,the pitch lock is released.• Even if the connection between units in the BPM SYNC status iscancelled, pitch lock is maintained.• When the track on the “Master” unit changes, the “Master”settings are transferred to the initially synced “Slave”. At this time, ifthe pitch is locked for the “Master” device, pitch lock is maintained.NOTEThis setting cannot be used unless one of the devices is set to“Master”.HOT CUE 1 ~ 4SEL.BPM SYNCMIDI BANK 2 MIDI13 Pitch slider
