Please note - your DAW may not automatically select the Scarlett 2i4 as its default I/O device. In this case, you must manually select ‘Scarlett 2i4’ as the driver on your DAW’s Audio Setup* page. Please refer to your DAW’s documentation (or Help files) if you are unsure where to select the ASIO or Core Audio driver. The example below shows the correct configuration in the Ableton Live Lite Preferences panel (Mac version shown).
Example of Usage The Scarlett 2i4 is an excellent choice for several different recording and monitoring applications. Some typical configurations are shown below.
If you are using a capacitor (condenser) microphone, press the 48V button to supply phantom power to the mic. Don’t turn this on if you’re using any other type of mic. Each channel of the Scarlett 2i4 has a PAD button on the front panel; pressing this reduces the input sensitivity by 10 dB. You may find this useful if you are feeding the input from a line level source when the output is particularly “hot”.
stereo amplifier; in this case, the outputs should be connected to the amplifier’s inputs.
Connecting Scarlett 2i4 to a DJ mixer The Scarlett 2i4 makes an excellent interface between a laptop running DJ software and the channels of a DJ mixer. In this setup, Outputs 1 and 2 can be connected to Line Inputs 1 and 2 of an external DJ mixer, and Outputs 3 and 4 to Line Inputs 3 and 4. Connecting in this way means that all mixer facilities, such as EQs and crossfading, are easily accessible.
