I'm not sure if I know what you mean by different curves, the choices are Trinnov off or on. If it is on you can calibrate using the microphone at 3 listening positions. (Rather than actual physical locations you could run different profiles with different room acoustic properites - i.e. change in furniture placement, drapes open / closed, etc). But when Trinnov runs it is all automatic calculating horizontal angle, vertical angle, distance, -6dB point, Level and delay for each speaker.
If Trinnov is off you can manually set 2 profiles - ref 1 and ref 2 which can be stored in memory. Manual profiles adjust speakers used, cross over frequency for each, speaker distance, speaker level trim, LFE level. There is no adjustment for horizontal and vertical spatial adjustment like Trinnov calculates within the manual mode.
If you are using Trinnov EQ for each position you can adjust:
1. Room EQ -
B. Phile 1 - to adjust the frequency response of the all the speakers except the front speakers to match to characteristics of the front speakers.
C. Phile 2 - To adjust only the low frequency response of all the speakers to correct for the acoustic properties of your room.
D. Natural - to adjust the frequency response of all the speakers with a modest boost below 200 Hz and a slight cut above 10 kHz
2. Trinnov Spatial mapping
A. DLY + LVL - The distance and speaker levels are compensated so that all speakers seem to be the same distance from the listener and all speakers seem to be the same level.
B. Autoroute - each input channel is routed to the nearest speaker, according to the input stream format and to the ITU standards
C. 2D remap - no elevation compensation is done, the remapping calculation takes into account the coordinates of the speakers in the horizontal plane only.
D. 3D Remap - the remapping matrix is computed according to all the Trinnov criteria in order to produce the best spatial correction
3. Trinnov Remapping
A. Cinema - front speakers are suppose to be +22.5 and -22.5 degrees from the center channel
B. Music - the are supposed to be +30 and -30 degrees
4. Cinema EQ - on or off - on to compensate for edgy or shrill move sound tracks.
I prefer natural Room EQ and 3D remap. Does that answer your question?
