• Ballistics: Rotating this knob adjusts the float. Pressing and then
rotating adjusts the bar. Ballistic timings are valid only at 48 kHz.
• Limits: Rotating this knob sets the upper limit of the display.
Pressing and then rotating sets the lower limit. Top and bottom
limits are adjustable in 1 dB increments. This function is available
on the custom meter scale only.
• Lower Scale: (This function is available on the custom meter scale
only.) This knob controls the size of the lower part of the scale in
relation to the overall scale. You can reduce the size of the lower
part of the scale to allow more accuracy in viewing the upper part.
Rotating this button sets the division point between the upper and
lower parts of the scale in 1 dBr increments and it moves the arrow
in the meter display up or down. As you adjust the division, the
percent of full scale (%FS) in the Size section of this function, is
continuously recalculated. Likewise, if the Limits control is
adjusted, the %FS is also recalculated.
