API 550A Controls
Band Controls The three EQ bands (HF/MF/LF) are controlled by
dual-concentric switches. The inner knob controls the
band frequency and the outer knob controls the band
gain. Available values for these controls are listed in
Table 7 below.
Frequency
Frequency determines the center frequency of the
band when the filter is in peak mode and the cutoff fre-
quency when the filter is in shelf mode. The frequency for the band can be set
using any of these four methods:
1.
Drag the inner concentric knob to the desired value, or
2.
Hover over the inner concentric knob then use the mouse scroll wheel, or
3.
Click directly on the frequency value label to switch to that value, or
4.
Click on the band label (HF/MF/LF) or units label (kHz/Hz) to cycle
through available values.
Gain
The gain for the band can be set using any of these three methods:
1.
Drag the outer concentric knob handle to the desired value, or
2.
Click the “+” or “–” text labels to increment/decrement values, or
3.
Hover over the outer concentric knob then use the mouse scroll wheel, or
4.
Click directly on the gain value label to switch to that value (this method
works only when Controls Mode is set to “Circular” in the UAD Control
Panel Configuration panel).
