Figure 2–5 Audio Menu 2

Pressing the Flat button brightens the Flat setting and darkens the

Bass and Treble settings to brown, and produces a flat response. This

is the default setting. However, the Bass and Treble settings are

retained so you can recall them the the next time you press the Flat

button, the Bass button, or the Treble button.

Press either Treble or Bass and then rotate the Channel Volume to

increase or decrease the response of each. The range is

± 12 dB in 2 dB steps.

Pressing Bass a second time moves the highlight to the Low Cut

setting. Pressing the Channel Volume knob turns low cut on or off.

When it is turned on, an additional low cut filter is engaged in the

speaker path.

Press the Channel Volume knob for at least three seconds to return to

the Main Screen.
