Output Control And Level Meter; Headphone Output - Focusrite Scarlett 4i4 4th Gen User Manual

Note
Air Presence & Drive is only available at up to 96kHz, you cannot use it at quad-band
(176.4kHz and 192 kHz) sample rates.

Output Control and Level Meter

The Output control and Output level meter are related to the signals going to Outputs 1 and 2 on
the back of your Scarlett 4i4, the outputs you'd most often connect to monitor speakers.
The Output control sets the level at the outputs from nothing (fully anti-clockwise) to full-scale
output (fully clockwise).
The Output Level meter around the Output level control is a pre-fade meter (it is not affected by
the control's position) showing you the signal level coming from your computer.

Headphone Output

The headphone output is a 6.35mm (¼") TRS jack. Many headphones have a 3.5mm TRS jack, to
connect them to your Scarlett 4i4 you must use a TRS 6.35mm to 3.5mm adaptor.
The control above the headphone output controls the level going to your headphones.
Some higher impedance headphones may be quiet using them with a Scarlett 4i4, we
recommend using headphones with an impedance up to 300Ω.
Note
Some headphones and jack adaptors may have TS or TRRS connectors, for example,
if they have a microphone or volume control built into the cable. It's unlikely these
headphones will work properly. If you're having issues, use headphones and a jack
adaptor with TRS jack connectors.
Speaker, Line, and Headphone Output Routing
The headphone output can be assigned a combination of hardware inputs (direct monitoring)
and software playback channels.
For more information on creating a mix for your headphone output, see
Mixer [36].
The Scarlett 4i4 headphones output is independent of the line outputs 1/2 and 3/4 giving you a
completely independent headphone mix.
