The IBP can be a little baffling at first. It doesn't help that the button controls aren't clearly marked for in/out function, but the manual clears this up so it's worth repeating here for reference.

Phase Adjust

90°/180° This switch determines the range of the Phase Adjust parameter. This is useful when finer Phase Adjust resolution is desired.

When the switch is disengaged, the Phase Adjust range is 180°.

When the switch is engaged (darker), the Phase Adjust range is 90°.

Phase Center

Lo/Hi This switch sets the range of frequency emphasis.

When the switch is disengaged (lighter), the Phase Center range is Hi.

When the switch is engaged (darker), the Phase Center range is Lo.

Note: Use of the 90°/180° and Lo/Hi parameters are typically used for in-

dividual tone signals such as a kick drum or toms as opposed to program ma-

terial.

So the lower or latter indication refers to the button "up" position. This could be marked better.

The delay adjust is just that, a simple sample delay, from 0 to 4mSec. Meaning all frequencies are delayed the exact same amount. So I won't bother showing its effect here.

Note that the phase plots wrap, i.e. the first plot below indicates the phase at about 20kHz is 360 degrees.
