The bottom half of the panel is dedicated to the hardware outputs of the
Mobile I/O. Much like the analog inputs, each of the eight analog outputs
has a set of controls associated with it. The controls are similar to the analog
input controls. Each output channel has:
1. Parameter Popup control
• The Parameter Popup control allows you to save, recall, and manage all of
the parameters associated with an analog output in one place. The control
is documented in detail later in this chapter (see: “
Parameter Popup
Controls ” on page 50). All presets are automatically shared between all
of the output channels.
2. Level Standard popup menu
• This control allows you to select the output level for the channel. The
available choices are:
• Line +4
This format supports output levels up to +26 dBu. The standard set-
ting with the trim knob set to 0dB yields a +24dBu output when the
digital signal driving the DAC is 0dBFS. This corresponds to +4 dBu
nominal with 20dB of digital headroom. You can use the trim knob to
adjust the analog output level to be consistent with the needs of
other audio gear. The output impedance is approximately 50 Ohms.
This format is appropriate for interfacing with professional audio
equipment.
• Line -10
This format supports a nominal output level of -10dBV with 20 dB of
digital headroom. You can use the trim knob to adjust the analog out-
