There are three types of volume adjustments: with the TRIM control, with the channel faders and with the MASTER LEVEL control. What is the difference between them?
TRIM: This adjusts the audio level input to the deck section or to the respective channels from an external device.
Channel faders: These adjust the audio level output from the respective channels for mixing.
MASTER LEVEL: This adjusts the audio level output to an external device from the DDJ-SR.
