A Music and Sound Quiz

[White Fox]

OK...

 

First off, if you know the answer for sure here let's wait a bit. Give those who don't a chance for some fun. Two or three days, and let people guess the answers. Also, please do NOT google the answer. That isn't any fun for anyone. Let's see how many people guess correctly...

 

1. Many of our "Home Theater" Systems today make use of four or five small speakers for to sort the treble into many different channels. And the base is often carried in one low frequency woofer speaker.

 

Here ist he first question. Is this idea new or was it used when stereo Hi Fidelity units first came out so many decades ago. Did some of them have two treble speakers, with one "middle" speaker for bass? Is it True that they had middle low frequency speakers in the initial days of stereo because low frequencies are not directional. and two separate hi frequency speakers for "Left", and "Right". Or is that false. They never had a single low frequency speaker.

 

Question 2. True...In the early days of stereo, records were made in both stereo and mono. Stereo records were more expensive. Or False. When stereo records came out mono were no longer available from then on.

 

Any guesses anyone?

OK, you can translate in a couple of days once everyone has had a chance to participate...

 

I knew that You, OFF, and BrGr would know this one for sure...

Totally out of my area of expertise, but I'll take a shot at one of 'em.

 

(1) Not a clue here ... Won't even guess. Over my head.

 

(2) I think it's Option One - When records first became available, mono and stereo records were available, with mono appealing to the more budget conscious consumers.

Question 1:

 

Bi-amped or tri-amped sound systems have existed since, at least 1930 or 1940. Electro Voice "Voice of the Theater" speakers have been used in movie theaters practically since "talkies" were invented. The original Electro Voice "V.O.T." speakers had two separate speakers for different frequencies of sound. One larger cone for lower frequencies and one or more smaller cones for higher frequencies. Each set of speakers is powered by a separate amplifier. This is done to keep the low frequency speakers from "eating up" all the power from the amplifier, thereby allowing for better sounding bass with out losing the high frequencies.

 

Question 2:

 

I know that records were produced in both monaural and stereo during the same period of years. Many records of the day advertised "In Stereo!" right on the cover. Monophonic records were produced with "hill and dale" grooves where the needle moves up and down, in the vertical plane only. The first stereo records that were invented were incompatible with old mono phonographs and they were shortly replaced by a system that was playable on old mono turntables. (But you would only hear the sound in mono.) Popular wisdom of the day dictated that it was bad to play stereo records on mono turntables because the old needles would damage the grooves. Today, this would not be a problem because, even if the pickup cartridge is mono the stylus is designed to move freely in the groove without damaging the records.

 

This brings us to the question of the cost of stereo records versus mono. Yes, they WERE more expensive, at first, because the early system required two mono cutting machines be bolted together in order to cut stereo grooves. Thus, it was twice as expensive to produce stereo records as it was to produce mono. Later on, after production costs came down, stereo records became cheaper but they were STILL more expensive than mono, not because of any increase in production costs but because the public perceived a greater value in stereo records. Therefore, record companies could demand a higher price for stereo records.

 

This very same principle carried over when the record companies switched to CDs instead of vinyl. Even though CDs are cheaper to produce than vinyl, they are more expensive because most people think CDs are better than vinyl. Since they are "digital quality" people are willing to pay more for them. This happened again when DVDs replaced VHS video tapes. It is happening yet again now that Blu-Ray is being promoted as an improvement over DVDs. Only this time, the public is getting wise. Blu-ray sales have been quite flat because the public isn't willing to pay a premium price for Blu-Ray over DVD. They have been fooled one time too many.

 

Consequently, movie studios are dropping the price of Blu-Ray movies because not enough people are buying them.

This is a translation of the gobbeldy gook above?

 

[White Fox]

Yep,that is Worker's specialty. His answer is more complicated than mine would have been. But he has the knowledge to back it up.

 

But yes indeed, there were small hi fidelity systems made way back in the old days with two separate channels for treble as those sounds are directional, and one bass speaker (more expensive of course) for the supposedly non directional low frequency signals. One left speaker. One right speaker. And one middle speaker for bass. And of course it is used today to bring stuff out ultra cheap!

 

And for records. Yep, there was a time when you could purchase mono OR stereo. As you said JG. For the high spenders you had stereo. For the cheap bastard... (sorry typing error) for the cheap individuals like me there were the mono records.

It was in ROT13. Rotate the letters of the alphabet 13 places.

A = N

B = O

C = P

and so on...

 

This is done because it is very easy to decode. Just rotate the letters 13 places again.

N = A

O = B

P = C

 

 

It is done so that people who want to read it can but people who don't want to read it don't get their game spoiled.

Happens to the best of us ...

Interesting. I would have translated ROT13 as the runt of a very large litter.
