12.0 Room Curve and Add Curve
Room Curves
Quick Reference
Room Curve will convert an RTA display of bars and
convert it to an eq curve.
Add Curve will add a stored eq curve to the current eq
curve.
These two utilities are to be found in the RTA Menu and can be
accessed by pressing the RTA key and then selecting one of them using
the speed strip.
Each environment in which the remote is used will have a
characteristic response curve which can be measured and stored using
the Real Time Analyser built into the FPC-900r. This curve will be a
record of the frequency response of the room either flat or after the
user has added equalisation to the sound source. The FPC-900r has
twelve program memories set aside for storing these room curve
records.
It may be that a good sound has been created by careful use of the
Varicurve equalisers and the resulting, adjusted room response is
recorded to either duplicate at a later time with a different band at the
same site or to use as a optimum equalisation response at a different
venue. Room curves created from an RTA response can, of course, be
used as the target response for the Auto EQ system detailed in the next
Section.
This utility is only available when there is an RTA bar display on the
screen. Selecting ROOMCV on the speed strip and turning the
parameter control will run the utility. The room curve algorithm
calculates filter parameters which best approximate the curve
produced by the
