Inst (Instrument) Button And Line Level Inputs - Focusrite Scarlett 4i4 4th Gen User Manual

Important
If you accidentally send 48V phantom power to the wrong input, most modern
microphones of other types, e.g., dynamic or ribbon, will not be damaged, but some
older microphones may be. If you're unsure, please check your microphone's user guide
to ensure it is safe to use with 48V phantom power.

Inst (Instrument) Button and Line Level Inputs

The Inst (Instrument) button only affects the 6.35mm (1/4") line input for the selected channel.
It changes it from an input suitable for line-level devices to an input better suited for instrument-
level devices.
To enable or disable instrument mode for the 6.35mm (1/4") jack input, press the Inst button
once. Green shows Inst is enabled, and white shows Inst is disabled. When you enable Inst and
connect a jack to your Scarlett, the minimum gain for the input is changed to +7dB.
Note
When the Inst light is white, the 6.35mm jack input is at line level.
When Inst is enabled (green) you can connect instrument-level devices to the 1/4" inputs such as,
but not limited to:
• Electric or electro-acoustic guitars directly and via effects pedals.
• Electric basses
• Acoustic instruments with pick-ups such as violins, double-basses etc.
When Inst is disabled (white) you can connect line-level devices to the 6.35mm (1/4") inputs such
as, but not limited to:
• Synthesisers
• Keyboards
• Drum Machines
• External Microphone Preamps
Instrument/Line Software Control
