4.4 Monitor vs. Master Level

It’s important to make a distinction between MONITOR LEVEL control and level of the stereo bus output, as controlled by the

MASTER FADER.

When using the US-224’s analog inputs, only the TRIM controls actually affect the input level to the audio software application. When using the US-224’s Digital inputs, the digital audio data received at the US-224’s digital input is passed directly to the audio application without any gain or other modifications.

When monitoring audio playback from the application via the US-224, the level is controlled by that track’s software gain control (which, in turn, is controlled by the US- 428’s channel FADERs), the MASTER FADER, and the LINE OUT or PHONES OUT level controls.

The LINE OUT and PHONES level controls directly affect the audio levels that appear on the LINE OUTPUT and PHONES jacks, respectively. The audio level produced at the DIGITAL OUTPUT is not affected by either control.

The MASTER FADER is the final level control affecting the digital stereo output to the application, consequently changes made to the MASTER FADER level will also affect the output level to the speakers.

Thus, if you want to simply reduce the volume of your listening environment, you’ll want to use the MONITOR LEVEL control to do this without affecting the level of your stereo mix.
