The outputs can be connected to amplifiers and speakers, powered monitors, headphones, an audio
mixer or any other analogue or digital audio equipment that you wish to use. Although all inputs and
outputs on the Scarlett 18i20 are routed directly to and from your DAW for recording and playback,
you can configure the routing within your DAW in order to meet your precise needs.
The accompanying software application, Focusrite Control, provides further routing and monitoring
options, as well as the ability to control global hardware settings such as sample rate and
synchronisation.
Two completely new features have been added to the Third Generation 18i20: talkback and
secondary monitor speaker switching. The Talkback function uses the built-in mic to let you speak
to the musicians through their headphones, though the talkback signal may alternatively be routed
to any other combination of outputs. The ALT function lets you connect a second pair of monitor
loudspeakers to Line Outputs 3 and 4 and switch between the pairs to reference your mix on a
different set of speakers. Both functions can be activated from the front panel but they can also be
configured and selected on-screen from Focusrite Control.
All inputs on the Scarlett 18i20 are routed directly to your DAW software for recording, but Focusrite
Control also allows you to route these signals internally within the device to the outputs so that you
can monitor the audio signals with ultra-low latency - before they arrive at your DAW, should you
need to do so.
The Scarlett 18i20 also has connectors for sending and receiving MIDI data, and for transmitting
word clock to ensure synchronisation with other items of digital audio equipment.
