The SEND/RETURN terminal enables audio output from the channel selected by the effect channel switches in the BEAT FX section (1 - 4 channel, MIC, CROSS FADER A/B or MASTER) to an external device.
You can apply Beat FX and external FX at the same time thanks to the independent Send/Return section.
You can change the SEND/RETURN effect routing using the [SEND/RETURN] switch and [RETURN TYPE] switch.
Selectable effect routings are as follows:
-[SEND/RETURN] switch
You can change terminals for SEND/RETURN.
When you select [1/4" JACK], the audio signals input to/output from the [SEND/RETURN] terminal on the back of the unit, in the same way as the DJM-900NXS.
When you select [USB], the audio signals input to/output from the USB terminal at the upper right section of the operation panel. This enables digital SEND/RETURN to Inter-App Audio effector applications on an iOS device such as RMX-1000 for iPad without deteriorating sound quality.
-[RETURN TYPE] switch
You can change RETURN effect routing.
When you select [AUX], the sound with the effect returns to a different channel where [RETURN AUX] is selected at each channel input switch (1 - 4).
When you select [INSERT], the sound with the effect returns to the same position selected by the effect channel switch. You can completely switch the original sound to the sound with the SEND/RETURN effect.
