Why does sound come out of my PC/Mac or the built-in speaker of my mobile device incorrectly?

■rekordbox for Mac/Windows
When PC Master Out is turned on, you can output the audio from your PC/Mac's speaker.

■rekordbox for iOS/Android
Sound isn't supposed to come out of the mobile device when one is connected to the unit. Connect a power speaker, power amplifier, etc. to the [MASTER] output terminal on the unit to output sound.

Note:
When connecting an iPhone or iPad with a USB Type-C port, you can easily enjoy DJing with low latency without external speakers by the following methods.
Enable [Output audio from the iPhone speaker only] or [Output audio from the iPad speaker only] in [Settings] > [Audio] in rekordbox for iOS.
If enabled, audio output and some operations will be restricted as follows.
・Listening with headphones connected to the unit is not possible.
・The audio output can't be adjusted by turning the [MASTER LEVEL] knob on the unit.
・No master audio is output from the unit.
・Audio from the microphone connected to the unit won't be output from the mobile device.
