Within the peak limiter field to the left of the hit monitor is a meter that displays the limiter gain currently applied The meter will not register if limiting is not active The values it can display are 4dB to slightly less than OdB in increments of 1 dB Note that increasing limiter attenuation moves the meter downwards contrary to the motion of the coarse peak meter A B Registers The A and B registers store the band input processor and peak limiter parameters in a local area outside of the workstation host for quick comparisons The round unlabeled buttons to the right under the downward ar row store the operational parameters to the correspond ing register The store button will turn blue whenever the operational parameter set matches that in the register else it will be colorless The square buttons to the left under the upward arrow transfer the parameters in the labeled register to the operational parameters All Bands Bypass The all bands bypass button activates and disables all dynamic equalization for comparative evaluation DEQ In signifies that dynamic equalization is on DEQ Out signifies that it is off When a band is in solo mode this button enters a special mode with a Solo On label Clicking the button in this special mode will deactivate solo mode Effect Bypass The effect bypass button is equivalent to the bypass function for the host workstation This button is acti vated by a

8. To this point this issue has not been resolved It is best practice to dismiss the about window using the red button in the upper left corner once the parameter window settings are made Parameter Window Level The parameter window competes with other windows in the workstation project for visibility If the work routine requires accessing the parameter window only on occasion it should be sufficient to leave the parameter window on the base level of the workstation which is the default for the initial instance of DynPEQ If on the other hand the routine requires accessing and referenc ing the parameter window often the parameter window level selector allows the option to raise the display level of the parameter window above the workstation win dows so that the parameter window will float above the workstation level If this floating window level obscures important elements of your project to the detriment of workflow the parameter window level selector can then be reset to return the parameter window to the worksta tion base level Operation Tips The maximum peak indicator can be used to record the highest level encountered with a source program and dynamic parametric equalizer settings To attain a setting that will adjust this peak to 0 dB or the highest setting without encountering a limiter hit one may wish to adjust the input level to accomplish this Adjusting the input level however cannot guarantee this unless
