Hi Again,
Audyssey initially produced some strange results for me, but i did some research and finally managed to get a sound i'm very happy with - remember its your system and you have to be happy with the sound.
Some tips i picked up to get Audyssey working for me:
- First make sure the calibration microphone is set up and positioned correctly. It should be at ear height when seated and MUST be pointed towards the ceilling. If you have high backed seats that could interfere with the sound path to the microphone, then raise the microphone above the seat back. Ideally the microphone should be positioned on a camera tripod or similar stand. The room should be as quiet as possible during calibration. Use three calibration positions as directed in the manual, not three measurements at one position.
- Turn up the crossover on the back of your subwoofer to the maximum and set the gain (also on the back of the subwoofer) to around 50%. Run the auto setup procedure and examine the results. If the sub trim levels in your amp are towards the extremes of the range, increase or reduce the gain (on the back of the sub) accordignly. For example - since your sub woofer trim is reported at minus 15db, it means the calibration has detected your sub as being too loud and is trying to reduce it. Hence i would decrease the gain (on the back of your sub) further and repeat the auto set-up until you get a trim value away from the extreme end of the range (close to zero would be ideal). The problem with a trim level at -15db is that the amp cannot go any further so for all you know, a trim of -20db could be required but thats outside the adjustable range of the amp.
- Once you get the sub trim at a reasonable level, concentrate on your other speakers. Next check the distance measurements recorded for your satelite speakers. This is easy to check with a tape measure - fine tune accordingly. The results are usually accurate but if they are a mile out, it signifies something is going wrong with your calibtation. Dont pay too much attention to the distance measurent reported for the sub, as Audyssey attempts to compensate for any delays originating from the LPF by changing the distance.
- Next check frequency cut off values reported by your amp. As a starting point check these against the specifications given for your particular speakers. Also bear in mind that the positioning of your sat speakers will have an effect on how much of the low frequency range Audyssey thinks they can handle. For example a corner position in your room is likely to generate more of a bass response over a speaker on a stand away from any walls. As a general rule, its ok to increase the crossovers but not to decrease them.
Next sit back, put on your favourite blu ray and enjoy the fruits of your hard work.
Lee.
