Connecting Scarlett 18i20 to loudspeakers
The 1/4” jack MAIN outputs on the rear panel (Line Outputs 1 and 2) will normally be used to drive
your primary monitoring speakers. Self-powered monitors incorporate internal amplifiers with a
volume control, and may be connected directly. Passive loudspeakers will require a separate stereo
amplifier; in this case, the rear panel outputs should be connected to the amplifier’s inputs.
All the line output connectors are 3-pole (TRS) ¼” (6.35 mm) jack sockets, and are electronically
balanced. Typical consumer (hi-fi) amplifiers and small powered monitors will probably have
unbalanced inputs, either on phono (RCA) sockets, or via a 3.5 mm 3-pole jack plug intended for
direct connection to a computer. In either case, use a suitable connecting cable with jack plugs at
one end.
Professional active monitors and professional power amplifiers will generally have balanced inputs.
When mixing, you might want to use several pairs of additional speakers (mid-field. near-field, etc.)
to check how well your mix translates to other types of speaker. You can connect additional pairs of
