I'll get back to you later about dates. In the meantime, I am going to try to figure out how to make a 5.1 out of my 2.0 PEAK. If you have a simple explanation you could post, that would be helpful. Seems like you have done this quite a bit. I don't always find the manual all that easy to follow. But I really should be patient and read this section again.
I assume you mean you have a Peak 2.0 system and you want to do a 5.1 PRIR measurement? You can't "make" a 5.1 PRIR from a 2.0 PRIR. You have to make a 5.1 or 7.1 PRIR during the measurement process. I know that might be obvious, but I just wanted clarify since your statement was not clear.
The process of creating a 5.1 or 7.1 PRIR from a 2.0 speaker system is not hard. It is a lot of steps though. But once you get the hang of it, it's pretty easy.
The key to the whole process is the setting, "Menu-SPK" , "Save at end" setting. Essentially you leave "save at end" set to NO until the last pair of measurements.
So here's an outline of the process for a 7.1 PRIR from two speakers:
1) Save at end: NO - do a measurement of the two speakers as Left and Right channel
2) Save at end: NO - face away from the speaker, and get closer to the speakers (move towards front of room, still equidistant from each speaker.) Do a measurement with those speaker as the
Ls and Rs channels
3)
Save at end: Yes - face away from the speakers and move to the sweet spot. Do a measurement with those speakers as the
Lb and Rb channels
Since the last measurement has "save at end:YES", once you are finished with that measurement, it will ask you to name and save your PRIR and you are done!
So that's the idea. There are other settings you have to change, but I just wanted to give you an overall idea of what you are doing.
Here's a more detailed outline of the steps:
- Do a CAL to check audio levels. Make sure you only have the L and R channels active.
- "Menu-SPK"
Save at end:NO
"Excitation Menu" - I set it to 12seconds, 1 pass
- In that same menu, select "Speaker Mode Menu" - set "Speaker Mode:LR"
- Exit out of all the menus
- Press SPK
- Turn all channels off except the L and R channel (usually channel 1 and 2 are on and all others off). To turn the channels off, press the corresponding numbers on the remote.
- Press OK to start the PRIR measurement.
- Once the measurement is done, go back to the "menu-SPK" menu
- Leave everything the same, except select "Speaker Mode Menu" - set "Speaker Mode:LsRs"
- Exit out of the menus
- Press SPK
- Leave all the other channels alone. Just turn on the Ls and Rs channels (usually channel 5 and 6). To turn the channels on, press the corresponding numbers on the remote.
- Move closer towards the front of the room and then turn around and face away from the speakers. Press OK to start the PRIR measurement. (To know where to look for "Look left" and "Look right" I use a laser level and find points on the back of the room that are 30degrees to each side of center from your current position so I know where to look.)
- Once the measurement is done, go back to the "menu-SPK" menu
- Change "Save at end:YES";
- Select "Speaker Mode Menu" - set "Speaker Mode:LbRb"
- Exit out of the menus
- Press SPK
- Leave all the other channels alone. Just turn on the Lb and Rb channels (usually channel 7 and 8). To turn the channels on, press the corresponding numbers on the remote.
- Move back to the sweet spot and then turn around and face away from the speakers. Press OK to start the PRIR measurement. (To know where to look for "Look left" and "Look right" I use a laser level and find points on the back of the room that are 30degrees to each side of center so I know where to look. These points will be different than the Ls and Rs points.)
- Once this measurement is done, since you had "Save at end:YES", the PRIR measurement is done and you are prompted to enter the PRIR name and description.
- Keep pressing OK until you are back at the main screen.
- You now have your new PRIR measurement stored in memory position 64
- The first thing I do at this point is copy the PRIR to another internal memory location since position 64 will get automatically overwritten the next time you do a PRIR. Then I also copy it to the SD card just in case.
- Now load your new PRIR into a preset and check it to make sure it sounds OK. This step is VERY important since I have found all sorts of problems with PRIR measurements. I even like to compare it to some of my best PRIR's to make sure I got a good one.
There are actually a lot of other things to check, but I didn't want to have 50 steps!
Again, I find the key to this whole process is really understanding what you're doing from a overall standpoint so it all makes sense to you. If you are just following the steps and have no idea what you're doing, it can get very frustrating and confusing especially if something goes wrong.
It's not that hard, except the first few times.
Good luck!
Please let me know if I made any mistakes above.
