Orange County Speaker Repair can repair Altec speakers and compression drivers. They are in Garden Grove, CA, just east of L.A. http://www.speakerrepair.com/ The model you have is either the model 19 (if the horn is metal) or the model 14 (if the horn is plastic).
When nuclear weapons testing ceased, analog tape machines were still the norm. While the machines that the military used for the nuclear experiements were professional grade (Ampex and Berlant-Concertone), the microphones and the pickup locations of the sound were definately secondary...
Download a free copy of TrueRTA (www.trueaudio.com) which has 1 octave resolution - good enough for general HT subwoofer calibration. Set the generator to "pink noise" and run the output of your soundcard to your receiver. The upgrades of this program are cheap if you want resolution tup to...
Of course the debate can be fanned forever if that is what is desired. I would encourage you to seek out someone who encodes DVD sound at an authoring house and try to sort out the differences yourself if interested. All my experience points to them both sounding pretty much equal at the end...
The comparison shootout was with the theatrical codecs. Yes, I don't eliminate the possibliity that there are genuine differences in sound between the codecs. However I have found that in the vast majority of instances where I have made comparisons, the differences that were directly...
You are quite right. However I also said somewhere in one of those threads that while I preferred DTS, I knew why I did, and it had nothing to do with the DTS codec itself, but rather with the way the sound was altered. I just liked their EQ and the way the surrounds were pumped up. There was...
That would seem to be a logical assumption. They are, after all, in the marketing loop when they offer an alternative sound format on their DVDs. I don't have any information one way or another on this however.
Aside from higher levels of the surrounds seeming "more enveloping", the Fletcher-Munson curves which plot the frequency "response" verses SPL relationships of our ears can enter into the picture. As the sound pressure level is increased, the audibility of bass frequences (and to a certain...
I figured marketing played very heavily into it, considering DTS's reputation for hype. Lossy encoding would seem to trump any audible benefit of higher bit depth/higher sample rate original recordings, with any real-world audible difference being very minimal, if audible at all to the average...
Yes, it is distressing to see some of the marketing hype that gets foisted on the consumer, and I have posted extensively in an attempt to dispell some of these myths. I have found that the Dolby Digital tracks sound the most like what I hear on the masters in controlled experiments, but it...
When I do comparisons, I either listen directly from my preamp/processor, or take the analog outputs of this device into the ProTools HD. Admittedly while this is not as pure a method of extraction as it might be, it is nonetheless the mode that an average consumer would use in actually...
>>>So I am left wondering whose experiences do I accept as being valid; and who is showing off, like a noisy windbag, to the group. One set of salient points remains clear. Roger Dressler, a well-known and highly respected professional in the field, is willing to put his reputation on the...
>>>Yes, but are there any other ways possible to get the surround effects? For example, is there a way to get the sound of a plane flying overhead without using some sort of processing. Is it even possible to encode that much information on a film without any compression? I have noticed that...
Yes, do you people REALLY expect me or anybody else to reveal an actual name in a public forum? It is nonsense to demand that somebody publish their identity just "to taken seriously". I work freelance (as does just about everybody in my field) and do not represent a company as Mr. Dressler...
The comparisons were and are done at my studio. They are comparisons of the original music masters as delivered to the dubbing stage, and the print masters from the dubbing stage to the DVD copy of the movies those masters have been mixed into. The original master elements are played back on the...
The whole argument about DD vs DTS is kind of like arguing about which of two extremely ugly women is "prettier". BOTH DTS and Dolby Digital stink as far as ultimate sound quality goes when either of them is compared to the original print master. EVEN IN THE HOME ENVIRONMENT! >>>How so? I...
Feeling a bit testy there Roger? :frowning: At any rate, as I am sure you know, the motion picture dubbing stage is an ideal venue to do a comparison between the uncompressed print master and Dolby Digital encoded copy of this source. It is the only place where you can hear the master played...
>>>>If I visit a mixing stage, will I be able to compare the source to the Dolby Digital or DTS tracks that will later appear on the DVD? If they don't make the encoded tracks right at the dubbing stage, how did you make the comparison? Do you bring the DVD back to the stage 6 months later and...
>>>Whether or not the sound designer/engineer/mixer ect., is an individual or a team is irrelevent. The point is that the DTS and DD soundtracks are different. And in the movies I've listen to, the differences are consistant.
>>> So then why they are credited a such?[sound designer]It is true that it gets done by a team of people but in many cases one person gets the credit,because of his "design" that might get implemented by his team,but it is his design.Yes the director has a final say,and some are more involved...
There is no such thing as "THE sound engineer" on movies. There are teams who mix the movie, there are teams that create the sound effects, there are teams that edit and loop the dialogue, and there are teams that create, record and edit the music (I am a member of this team). All of these...
Generally, studio monitors are made to take more abuse than home speakers. They are usually more revealing of flaws in recordings than a home speaker would be. Cost is also more of an issue in home speakers - some studio monitors get very expensive. Studio monitors are usually not a good...
>>>Fortunately, good quality powerful amplifiers have as much or more bias current than their smaller counterparts. So that really isn't true. I would think of a good high-powered amplifier as having its operating range extended farther upwards, but not reduced at the other end. Of course, this...
I copied this from another forum. I don't know if it's true, but it sounds logical at least: Basically, the more efficient your speakers are, the less gain you want from your power amplifier. A more powerful amplifier has more gain than a less powerful one, and the inherent noise from the...
This magazine has tons of ads and info on manufacturers of new output transformers and associated parts. There are actually quite a few companies making them! www.vacuumtube.com I use tubes for my front L,C,R speakers in an active bi-amped configuration. I use solid state for the side and...
