Universal Audio OX Operation Manual page 15

SPEAKER VOLUME (4)
This knob adjusts the loudness of the guitar speaker(s) connected at OX's rear panel TO
SPEAKER output jack. Six knob positions and five carefully crafted attenuation levels are
available.
Position 1 is the quietest available setting. Position 5 is the loudest available setting. At
position 0, the speaker is OFF for silent operation.
SPEAKER VOLUME does not change the signal level being routed into the digital
section, which receives signal before this loudness control. This feature allows you
to change the guitar speaker volume without changing levels at the LINE / MON,
HEADPHONE, and S/PDIF outputs.
Note: The guitar speaker volume is determined by the overall combination of
amplifier power and output impedance, guitar speaker impedance, and OX's rear
panel IMPEDANCE knob.
LINE OUT (5)
The signal level at OX's rear panel stereo LINE / MON outputs is adjusted with this
knob. LINE OUT does not change the level at OX's SPEAKER, HEADPHONE, or S/PDIF
outputs.
Rotating this knob fully counter-clockwise to the "0" position shuts off the LINE / MON
outputs.
HEADPHONE Knob (6)
The volume of OX's front panel stereo HEADPHONE output is adjusted with this knob.
HEADPHONE does not change the level at OX's SPEAKER, LINE / MON, or S/PDIF
outputs.
Rotating this knob fully counter-clockwise to the "0" position shuts off the HEADPHONE
output.
HEADPHONE Output (7)
This TRS stereo unbalanced output jack accepts standard ¼" stereo headphones.
Headphone volume is adjusted with the HEADPHONE knob above the jack.
Important: Changing RIG settings and/or presets can cause a sudden jump in
headphone output levels. Exercise caution when adjusting Rigs (via RIG knob or
OX software app) when HEADPHONE output is at higher levels.
