the level at the main monitor outputs on the rear panel, but can be configured in Scarlett
MixControl to adjust the level at any of the unit’s ten analogue outputs.
11. DIM and MUTE – two switches controlling the 18i20’s monitor outputs; DIM reduces the
output levels by 18 dB, while MUTE turns the outputs off. By default, these switches affect the
main monitor outputs 1 and 2, but may be configured in Scarlett MixControl to act on any of
the analogue outputs. The switches each have an associated LED (DIM: yellow, MUTE: red)
indicating that the function is selected.
12. VOLUME 01 and VOLUME 02 – connect one or two pairs of stereo headphones at the two ¼”
(6.25 mm) TRS jack sockets below the controls. The headphone outputs always carry the
signals that currently routed to analogue outputs 7/8 and 9/10 (as stereo pairs) in Scarlett
MixControl.
13. POWER - AC power switch and LED.
14. Rack ears for mounting the Scarlett 18i20 in a standard 19” equipment rack.
