    Audio quality of Apple TV/NetFlix HD Movie Soundtracks

    What I found more disappointing with the two titles I purchased from AppleTV was the picture quality of their HD coding. DVD thru the Oppo upscaler was the clear winner. I've stuck with BDs delivered from Netflix ever since.

    Dirac Live

    Does your sound card have >2 outputs? If so, can you not find some software to run to do the crossovers? Something like this Linkwitz-Riley VST would plug into AudioMulch.

    Trinnov ST2

    They are not excluding bug fixes or updates to such things as speaker config options (mappings) or any other tweaks they may wish to offer down the road. The Trinnov software is licensed. Even though it runs on a PC and could theoretically talk to other of their hardware platforms with different...

    To Equalize or Not to Equalize: That Is the Question

    Good questions. Not having used those devices, I can offer no insights there. I suspect this unit will not be your cup of tea, since even though it is analog on/out, it is DSP inside. Nonetheless, have a read of the PEQ-55 product information to get familiar with a great set of features aimed at...

    To Equalize or Not to Equalize: That Is the Question

    The Cello Pallete seems much more intuitive for me unless you want to take a deep dive and become conversant with the peculiarities of yesteryear mastering EQs. A stroll through great analog studio tools of the past is in the UAD Manual.pdf available here, describing their reincarnations as DAW...

    Speaker/Room calibration

    Err, that's because there are 4x 15" subwoofers in there. :rolleyes: Have you checked a room mode calculator? The room is 13' 4" wide. Plug it in.

    Speaker/Room calibration

    Umm, so one can hear the bass? How would that help the lateral modes?

    Speaker/Room calibration

    I agree, and suspect all the trapping at the front/rear of the room is doing rather little for the 40 Hz mode, as that rattles between the side walls so would still exist even if Bruce knocked the front/rear walls out of the building. The cool thing about these Evolution speakers is their...

    Speaker/Room calibration

    Ahh, ok. So it looks like those "woofer" locations are not doing much to cancel that 40 Hz mode. The new plot does show a much improved response, one that looks addressable by EQ, if that were an option... I understand the subs self-powered. Do you have access to the line level input signal...

    Speaker/Room calibration

    Bruce, is this plot showing the response of one speaker, or both? Could you run a plot with both driven as mono?

    Speaker/Room calibration

    Yes. That choice was driven by two factors. The option for a pair of midwall subs (one of the better Welti solutions) was not physically possible as a retrofit to the room. And the BassQ supports 4 sub outputs, so why not? The external EQ being the BassQ driving the subs. All other EQ happens...

    Speaker/Room calibration

    Consider what happens with an infinite bass trap: playing the speakers outside. There is no dip. The dip means the bass is in fact not being trapped. It's so much more effective to kill these bass modes with multiple subs, no room should be designed without them.

    Speaker/Room calibration

    How much of that trapping reaches 6' from the hard walls?

    Speaker/Room calibration

    Neither speaker controls nor DRC will have any effect on the 40 Hz null. Adding a subwoofer or two, now that's a different story. Or, as we may soon find out, so may be driving the two mains together.
  15. R

    Speaker/Room calibration

    A room mode calculator shows the first length mode is 26 Hz and width is 42 Hz. And apparently neither do bass traps. :( That null at 40 Hz is pretty severe, and I suspect is not what you are hearing because you are measuring each speaker by itself, but playing them together. Assuming most...

    Trinnov ST2

    Sometimes it's fun riding back there in the rumble seats! :D C'mon, let that Seaton stretch its legs. [For other readers -- Ken has a sofa located behind the MLP. There is additional bass excitation provided free of charge.]

    Trinnov ST2

    That's weird. I see it, and apparently DonH sees it. Can you see it here?

    Trinnov ST2

    It not only overdrove the subs at higher levels, but exposed low frequency junk on movies and music recordings that seemed unintended at best, so I toned it down. The Harman curve is much more practical. I visited RUR's system over the weekend and subjected him to that curve, using the 1/3d...

    Trinnov ST2

    They offered curves with different amounts of bass. None of which worked for my sensibilities. My target in the bass looks more like Harman's Synthesis or Holman's -30 dB curve from his "Loudness Compensation: Use and Abuse." Figure 3 as attached. The black line above is the Synthesis, the...

    Trinnov ST2

    IMHO, the main issue is no user control over the target curve. It's a deal killer for me. Dirac Live has target curve editing (much like Audyssey Pro and Trinnov's own systems), and according to Carl Huff, Dirac is sprucing up the U/I, so the RS-20i and Carl's own eminent standalone EQs ought to...

    When we learn to read the Constitution as intended I'll start listening to performances with period instruments. :rolleyes: :D

    Equalizers - Is it time to take them out of the closet?

    The need for equalization has nothing to do with bitrate compression. Any format can benefit from EQ. And as others have said, EQ cannot fix what lossy compression does, but it surely can reduce some of that glassiness that passes for "digital quality" internet radio. :rolleyes: I had the SAE...

    Massive Hum on Monarchy M-150 Power Conditioners.

    Good info. Could try a local electronics school, or a product testing or repair facility where they need to use exact line voltage -- or to bring up "dead" products slowly. A Variac is nothing esoteric. It's the comparison to 120v that will provide most insight. If you could either look at the...

    Massive Hum on Monarchy M-150 Power Conditioners.

    They were noisy on day 1, or has it increased over time? And the noise is the same even with no loads connected at all? If the transformer is not designed for the correct operating voltage range, it could be saturating the core, which leads to not only a distorted sine wave output but could make...

    Is Physical Media Still Relevant?

    I too found ripping my CDs to HDD was a liberating experience, which helped me enjoy long-ignored discs. And on some very rare occasion where a track has bothered me for years, I can now just load it into Adobe Audition and "fix" it. Like the 8-sec fade-in on Eva Cassidy's "Autumn Leaves" or the...

    Esoteric Beethoven SACD set

    Not sure to whom this is addressed. I have several SACDs, but no interest in ripping the CD layer, as that a) defeats the purpose in listening to the hi-res track, and b) misses out on the 5.1 mixes, which sometimes (but unfortunately not often enough) sound better than the stereo mixes. If I...

    Esoteric Beethoven SACD set

    When I want to extract CDs, I use iTunes. The iTunes in the MacBook Pro was open but would not recognize the disc, which it auto-ejected.

    Esoteric Beethoven SACD set

    If my MacBook Pro is any indication, your fears are well founded. It plays regular CDs fine, but will not play these hybrids. Yet my venerable Sony CDP-X55ES from mid '80s plays them fine.

    Latest news on Lexicon MP-20 Processor

    Luckily for us, there are experts who are drilling down into these matters year in and year out, such as at Audyssey, Dirac, Trinnov, and Harman, just to name the ones attached to commercial products. There are many more in academia whose output appears in numerous AES papers. To amplify on my...
