PUSH-BUTTON ROTARY ENCODERS
All of the knobs on the Audio Express front panel
are push-button digital rotary encoders. In many
cases, you can either push the knob, hold it in, or
turn it to make a setting.
POWER SWITCH
Push the PHONES knob to power on the Audio
Express. Push in and hold the knob to turn it off.
PHONES
From the factory, the PHONES jack (Figure 6-1)
mirrors the main outs, but it can mirror any other
output pair (digital or analog). See “Phones
Assign” on page 30.
VOLUME CONTROL FOR PHONES AND
MAIN OUTS
Push the PHONES knob repeatedly to cycle among
three volume control modes, as indicated by the
+main LED:
Figure 6-2: When the red “+main” LED is on, the PHONES knob
controls both the headphone out and the main outs.
As you turn the PHONES knob to adjust volume,
the MIC/INST ladder LEDs (Figure 6-1) provide
visual feedback.
