<font color='#000000'>I got the RXV-2400 last week. Here are my first impressions.
YPAO couldn't be simpler to use. It detected which speakers I have and their sizes correctly. It determined that my left front was further away than my right front. This may be because the front speakers are satellite/woofer systems and the woofer on the left one is a bit further away from my listening position. With this setting I found that sounds from the center were seeming to be coming more from the left so I opted to set the speaker distances to the same value using the manual setup.
The parametric EQ is interesting. I set it to optimize for bass accuracy. In my system it tended to boost low bass by 3-4 db, and cut bass at 350 hz; it also cut treble in the 13khz range, not sure why it was meddling up there since I was optimizing for bass? On one of my surrounds it had two settings centered at 250hz - this would only make sense if each setting was given a different "q", or frequency bandwidth - but there is no way to tell, the receiver only tells you center frequency and boost/cut db, not "q". BTW, on some forums people are saying that the parametric eq only has 1/3 octave center frequency resolution, this is wrong as I had one case were there was a setting at 200hz and another at 250hz.
Once the parametric eq is set, you cannot change it manually. You must choose between auto parametric eq and manual graphic eq. You can switch between parametric and graphic however. I left the graphic eq at its flat position and switched back and forth to gauge the effectiveness of the parametric eq vs no eq. I liked the paramtric eq results - more bass, a bit brighter sound. In comparison the flat eq sounds, well, flat
- not as lively. However, I did not correct for volume difference between the parametric and flat eq, so that may be affecting my judgement.
I have not tested the auto parametric eq for repeatability - eg if I run the setup over again will I get the same settings? Since there is no way that I know of to "save" my current settings, I'm reluctant to overwrite them with new ones which I may not like as much. If anyone knows how to save the configuration of the receiver and restore it later, I'd love to hear how to do it.
A few other points:
The multi-channel input is not associated with one or more input devices as it is on Onkyo and Sony receivers. Its a global setting, you either are using the multi-channel input or not, no matter which input device is selected. This makes it hard (impossible?) to set up a programmable remote to switch between devices without requiring the user to manually toggle multi-channel on or off when required.
You don't seem to be able to set the bass and treble from the remote - silly, since this is one setting where you want to be in your listening position when you make it.
The receiver doesn't remember the DSP or decode mode for different signal formats. On the Onkyo 801, you can set a different listening mode for each different signal type that comes from each input source. For example, if your DVD player
also plays compact discs and the DVD video signal is Dolby Digital and the compact disc signal is PCM, then you can set a different listening mode for each. For example, you can configure it to use pure stereo decoding for a PCM/Analog input on the DVD player, Dolby Pro Logic II Music for a Dolby Digital 2.0 signal on the DVD player, and THX for a 5.1 Dolby Digital signal on the DVD player. The Yamaha always selects the last compatible DSP/decoder used on that input.
The receiver does not remember the last setting for Dolby Digital EX and DTS ES - eg Auto, On, or Off - it always resets to "Auto" when powered off. This means you can't set it to always upsample 5.1 signals to 7.1 signals.
Overall, I really like the Yamaha.</font>
