Input Channel − USB Player Overview
The Overview screen provides an abbreviated view of
each section in the Input Channel USB Player function.
Only the primary controls are available for adjustment in
the overview.
1. Overview button – Selects the USB Player
Overview screen.
2. Reset button – Sets all the PEQ controls to their
factory default position.
3. Digital Nain knob – Compensates for digital audio
files that are too low or high in level.

PEQ section

4. Parametric EQ graph – A graphic representation of
the equalization curve based on the PEQ settings. The
trace dims to indicate that the PEQ is Out (disengaged).
• EQ graph vertical scale
level from -20 dB to +20 dB.
• EQ Nraph horizontal scale
frequency from 20 Hz to 20 kHz.
5. – Engages / disengages the equalizer.
EQ Out/In
6. EQ Handles – Touch, hold, and drag to change the
Frequency and Gain of the associated frequency band.
The frequency band button must be engaged to see
the handles.
7. button – Engages / disengages the high-pass filter. The HPF is variable with a range of 20 Hz to 2,000 Hz. It passes
High Pass filter
frequencies above the setting while cutting those below.
8. Parametric Band 1 and 2
of 20 Hz to 20 kHz.
9. Nain control knobs and readouts – Adjusts the gain at the frequency setting of the associated filter. Range of -15 dB to +15 dB.
10. Freq control knob – Sets the frequency of the associated filter.

Dynamics Section (AGC)

AGC is used to compensate for variations in the audio level of the source material. Refer to the AGC topic for complete details.
11. ANC display – Graphically shows the relationship of the controls as they are set.
12. ANC In switch – Engages / disengages the AGC.
13. meter – Indicates how much the signal level has been altered by the AGC. The center (0 dB) indicates that no gain change is being
Reduction
applied. Rightward movement of the meter indicates that gain is being applied. Leftward movement indicates attenuation (reduction) of the
signal level.
NOTE!: Select a control then use the Nudge buttons to adjust.
14. Max Target control – Sets the maximum level that the AGC will maintain.
15. Min Target control – Sets the minimum level that the AGC will attempt to maintain.
16. control – Sets a limit on the amount of gain the AGC will apply regardless of the target settings.
Max Nain
17. ANC Threshold control – Sets the level at which the AGC becomes active / inactive. Signals that fall below the threshold level are assumed to
be intentional silence and the AGC will apply no additional gain.
18. Release control – Adjusts how long the AGC holds its gain change after the input signal level changes.
