The p99rs is a tuner preamp you're most likely hearing clipping from you amps.

Also, I can't get my volume past 35 unless I stand outside the car. Sound pressure level is too much past that.

It does not clip at any volume or EQ setting when I had connected to an o-scope. You sure that the distortion ain't related to speakers/amps?

Does the P99 have a bright sound signature ? Some installer have comments that it is too sharp and bright ,will felt fatigue after prolong listening ? Any input on this ?

Absolutely not. If it sounds "bright" it's a tuning issue and nothing else!

Anybody have experience with iPhone 5 compability? Mainly what connection cord to use, and how Pandora/Spotify work.

Also you won't get any higher quality than that.
The P99RS bypasses the iPod DAC so which iPod you use won't matter.

AFAIK, stuff like Pandora and Spotify are BT only since the Lightning connection is digital.

My friend has an iPhone 5. Works with the P99 just the same as his previous iPhone 4. Also works with the third generation iPad.

The P99 is a very good bang-for-the-buck head unit. Also competition proven where I'm at.

Yes, there is a steep learning curve. But once you get the hang of it, tuning actually becomes straightforward.

Yuuuup. Thats one of the greatest features of the unit (bypassing the DAC's)

I simply stated classic because its the ideal ipod imo. If utilizing a format such as ALAC, WAV etc, the high capacity comes in handy. No other Ipod offers 160gigs.

Ah, gotcha. I agree. My old iPod video is on its last legs so a classic might be in my near future.

Has anyone tried to use the iPad mini with this deck? In general, I imagine most other decks operate the same. I'm wondering if you could use the iPad as a source and simply have it sit there and look cool. Most decks bypass the isource's interface entirely essentially locking you out of using it. I could test with my gen1 iPad but it's possible it'd behave differently.

Anyway... just wondering.

is bypassing the interface the same as bypassing the DAC's?
with the P99 you can choose to still use the ipod interface if you like too.

lol, i'll try a mini in a few weeks with my new install if you don't have a definite answer by then :P

I suppose if the iPhone 5 works with the P99, the iPad mini would too. They both use the new "Lightning" connector.

The P99 allows you to choose how to select songs from the iDevice. You can use the head unit, which locks-out the iDevice interface, or you can use the iDevice, making the P99 work like a simple aux-in.

If I have a passenger who has his/her own iDevice, I set the P99 to the second mode. Otherwise, it is in the first mode.

why do you think this is better than playing a CD with pink noise? thanks.

You'll have higher flexibility with direct control from a laptop. You can run several types of noise, sine sweeps, MLS sweeps - these you extract additional data from via FFT. These can be recorded inside an app like aRTA and saved as a wav file, a Memory card/CD can then be used for playback, it's just inconvenient. I recommend using aRTA in combination with RoomEQ, they have more features than most people asks for.

Major reasons why laptop generated is better than CD-PN:

*Easier control by far... imo
*Adjust level directly from the computer (including left-right channel mute)
*Look for resonances with generated tones
*Initial impulse can be used for measuring of T/A and phase
*Distortion measurements (sweeps and single tone via RTA)
*Group delay/waterfall/HD vs FR graphs/phase-impulse response measurements
*MLS allows for gated measurements (limited usability because of low resolution with fast gate times, which is required to eliminate sound contribution from early reflections)

-- Note that RTA/PN and swept sine are not the same thing. RTA in combination with pink noise plays all frequencies at the same time. Sine sweeps does only one tone at a time. Pink noise can be uncorrelated or correlated as well. Stereo noise is uncorrelated and mono noise is referred as correlated. Measure FR in stereo and T/A with mono PN if you use this approach --

The only problem I see with using a laptop is that you FR from the auxiliary input is not going to be the same as the FR from the CD transport. There will be some degradation of the signal due to the fact that you are at the mercy of the analog source of the laptop which then goes through an A/D converter to be processed digitally and then back to analog. Makes more sense to me to start with the source that you will be using to listen to music.

For measurement purposes that difference would be neglectable imo.

You would be surprised how much a half db makes in overall tonality...but then again, not everyone is building their system for competition either.

I recommend using aRTA in combination with RoomEQ, they have more features than most people asks for.

Major reasons why laptop generated is better than CD-PN:

*Easier control by far... imo
*Adjust level directly from the computer (including left-right channel mute)
*Look for resonances with generated tones
*Initial impulse can be used for measuring of T/A and phase
*Distortion measurements (sweeps and single tone via RTA)
*Group delay/waterfall/HD vs FR graphs/phase-impulse response measurements
*MLS allows for gated measurements (limited usability because of low resolution with fast gate times, which is required to eliminate sound contribution from early reflections)

-- Note that RTA/PN and swept sine are not the same thing. RTA in combination with pink noise plays all frequencies at the same time. Sine sweeps does only one tone at a time. Pink noise can be uncorrelated or correlated as well. Stereo noise is uncorrelated and mono noise is referred as correlated. Measure FR in stereo and T/A with mono PN if you use this approach --
thanks for the info. i am definitely going to try it. do you have any links for impulse measuring to determine T/A? I tried searching but could not find much. My truerta does have impulse.
