HELP me with my Seminar!

How is it related to your course ?? Are you thinking of going inside the electronics of the HiFis ??

Benks why don't you push arj, big ears or pritvi to give you some good links to informative sites. What component of hifi are you planning to talk about.

Here is a link which gives you good basic info and going too technical will make your college mates shiver in their pants......... just jokin'

Amplifiers :

http://linux.about.c...htm?terms=amplifiers

http://stereos.about.com/cs/audiofaq/g/amplifier.htm

Follow the links in blue at the bottom.more info there as well.

You can as well give them an educative seminar that PMPO and RMS ratings are all craps....

Use this web for more info on amps and speakers.

As you always write ..........my two cents

that's right i will be looking into the electronics side as well as the acoustics(cabinet design and configs, room, speaker placement, bass traps). will also figure crossovers,types of xovers, speaker systems(two way ,3 way , planar speakers), amplifier classes, bissing, impedance matching, capacitors, ground loop hum,cd technology and the future of audio software as well as a look at vinyl technology.
DAC's and transports will also have their share not to mention tubes and preamps and digital processors.
there is a lot but i wil cut some of them short and will focus mailny on stereo and a liitle on HT.

i just got a lot of material yesterday(got them xeroxed) will be getting the next(huge one) batch by next week. a lot of reading to do.

hence i need ur guidance.
Ben

Maaan thats quite a lot if you could care to share it with me after your seminar.............I too can learn

hey mohan,
i'm hoping that most of us can learn on the fly while i finish my seminar.
have to give an initial 15 minute talk on 4th of april so i need to get some things in order. the topic and the contents that i need to put in not to mention the paradigm that i need to follow to present it in a very comprehensive and as precise as possible way as there is way too much to talk about. all of my friends visualise a mini component system like a sony or a aiwa when we talk about audio systems. i hope to broaden the minds of my fellow peers on audio(if that'possible
and they have the patience to hear me out. mostly i'm doing this as a learning experience)
Ben

benks....

basics on speakers design. enjoy.

manek.

oops forgot to mention the kingpin

Benks why don't you push arj, big ears or pritvi to give you some good links to informative sites. What component of hifi are you planning to talk about.

Manek

benks....
only 15 minutes ? how will you cover all that stuff in 15 minutes ? I suggest you dont try and cover many topics but just the a few so that more can be spoken about each topic.

Whats the seminar format ?

Manek.

Benks i suggest you to generalise the topic and give some gyan in those 15 mins instead of cramming it with tech stuff.

guys, on 4th i have to give an intial report kind of thing to my seminar guide on what topics i will be talking on and wht exactly is teh subject and how it is relevant and what importance does it have in the real world.
regarding the format of the seminar. basically i need an intro a body and a conclusion.i have to figure out these things and importantly what goes whre(which follows which topic next) in the body of the seminar. i need a good and strong opening as well as closing.
Ben

hey guys,
just got my cell number.
its 9886574770.
cheers,
Ben

reminds me of my seminar days

Benks..the fun in this is in the research.

how about taking Class T digital amplifiers as a topic and doing some research on it ?

this is a hot topic and many say the future of amps is in that direction.

not only will it be a unique topic, but you are sure going to have a fun time learning up on it as well as , maybe even put together a DIY model (If you can get the tripath chips)which you can then use as a computer amplifier !

this will give you some info on this

ben i think you first have to form an opinion and put it forth as your topic. as in if u strongly believe that tubes are the best amps around to recreate music you should present that as your hypothesis and back it up with research on benefits of tubes and counter arguments and arguments highlighting the disadvantages of solid state. is there one type of tube amp you'd design if you had to make the future?

most everyone in college does 'general' research. it pays to have an opinion of your own and then structure a seminar around that opinion. which means you got to sit down alone and decide what is the one thing about music that moves you the most. is it subs? is it speaker placement? is it how tubes recreate that magic?

you can imagine how the structure of the seminar will drastically differ depending on what you pick as your focal point. of course in each topic you will cover the basics but the seminar will have a point to it instead of mass research just cut down to an hour. the point isnt to demonstrate your knowledge of the field. the point is to put forth to the world (your college) an innovative and creative opinion you have and then back it up with research. pretend you're an inventor or a pioneer. how would you like the future of audio to look like if it was all in your hands?

ps: i'm in adverstising and for a living i trick people daily in buying stuff. a good rule is keep it simple and leave your audience with just one thought. it becomes complicated otherwise and they miss the point u want to make - tubes are best amplifiers for example. then throw in ur research on how tubes evolved why they make sense even today, why better than solid state etc.

or - without a sub your home theatre is incomplete. so u'd probably cover independent subs and speakers like deftech with have built in subs and hte pros and cons of such designs and how you might build a completely new prototype, wiht suitable electronic arguments backing ur theory.

sorry for the rambling and reps in places. rushed.

if i remember right you're interested in working with burr brown. then make ur seminar about chips!

do research on what's the next hot thing in chips, where the technology is going and do a paper on that. if you have a really strong hunch or creative idea about a revolution in chips or improving some existing design, it might even help you get that job with burr brown. it shows interest and dedication from college times. trust me it'll help in some years.

maybe hand out packet of potato chips with a summary of your project on the packet to the guys judging you, and to the junta crowd before you start prattling away. wil hardly cost you anything and it might just add that impact and establish the topic in a fun way. now that's professional advice for free

hey Arj and steive,
that's a lot of food for thought.
i will seriously think it over tonight and arrive at a desicion.
yes u have made a point that it would sound overly complicated wth the audience not latching on to wha ti have to say if i broah the entire subject.
and yeah, burr brown and DAc's that really is a good one so is Tripaths' amps.
will think it ovwer and let u guys know latest by tomorrow morning
Ben

hey guys,
i decided to give a talk on transports and DACs like steive suggested but will skim over the entire stereo setup for abt 15-20 minutes with the rest of the 40 minutes dedicated to transports and DACs.
steve, u are right man. it would be very helpful for me int he future.
besides, my guide is one of the only two doctorates in my dept and now i have a reason to ask for a reccomendation letter from him for my higher studies.
already have some great sites picked out but will definitely appreciate all the help i can get. any old books or articles or webpages, anything and i'll be very grateful.
Cheers,
Ben

p.s: now i have to figure out a proper title for my seminar and get my things in to order.

hey stevie,

burr brown is now part of texas instruments.. so benks needs to think about getting into TI

yeah i know that.
i was pretty surprised when i found out a couple or so months ago.
BTW, u should be help me the most in this regard.
Cheers,
Ben

yeah ravi, ben comes from the city of IT and he gets it all backwards and lands up in TI

all the best ben! i wont be able to help you with the techie part of transports and dacs but if you need help with presentation or tips do let me know. thats my area of expertise. suggest you surf for industry contacts at burr brown and other related manufacturers and ask them pertinent questions like what's the future for transports, dacs whats the next big thing? whats an area that still needs to be cracked. should be of help in giving ur presentation a direction.

thanks fo rthe offer steve. surely will come to u for the presentation part as this Dr.guide of mine is a tough nut to crack.he isn't so easily impressed.
that's the reason i asked ravi as he has first hand knowledge and is already doing what i am aspiring to do. designing chips and tht to at the hly grail of chip companies.
.
Cheers,
Ben

benks,
would be glad to help you anyway I can.. I am into designing ADCs, so I have it all backwards too
I believe DACs along with class D amplifiers would have enough punch for presentations.. check out TIs PurePath technology too. I am personally interested in class D amplifiers for audiophile quality of the future - currently these are viewed as low cost solutions for portable and high power audio, but they are just as much potent as the BB DACs used in the early CD players were. When the CD technology was first introduced people were aghast at their music being chopped up and served up... there is a similar reaction to class-D now for high quality applications, but future developments to this techcnology might hold a different story! The all digital path right until the speaker would take all other equipment right out of the quality equation and might just provide the best fidelity!
Whats next...? Maybe chopping up of the speaker too and let it go digital!!

Hey Ravi,

I can already sense the tube guys trying to find your whereabouts, so they can come and lynch you

big-ears, er.. maybe there could be CDs made from Vinyl and digital amplifiers made using tubes, so both worlds would win out and my hide saved
well no offsense meant to the tube guys out there, and as usual, its one persons's opinion!

That's a good one.

Lump all the digital stuff into a tubular space-frame chassis and make everyone happy?

ravi,

I am definately part of the lynching mob



I'm sure viren would join me without hesitation.

manek.

uh oh... I should have known... trouble brewing...
hey manek, I grew up listening to a valve radio.. and played around with a few 6J6s, but not really listened to a good valve amp.. maybe if that happens sometime, you could roll your sleeves back down and Lyrita would have one more customer

ravi , I'll let you into a secret, I lynch with my sleeves rolled down....its this trick unsuspecting move to make the lynching painful and ugly



ravi you need to listen to valve amps of today. You have a few good choices in cayin, cadence, quad, prima luna, lyrita, CJ, nagra etc depending on your budget.

Honest to god, they are something else compared to ss. But then again you will know the magic of valves only when you hear them seriously.

manek.

hey guys,
there doesn't seem to be too much information on DACs and transports on the net. the ones i have come across so far have been more spcific on the chips rather than the implementation of the chip in the circuit and almost no information on how transports work and what kind of tech it is evolving into.
i'm seriously thinking to include more of the rest of the setup and cover the entire stereo setup since i already have a lot of material on hand not to mention the wealth of knowledge u find on the net.
if only u guys can guide me towards some more info on DACs and transports i will need to reevaluate the contents of my seminar.
will try to get away by telling my guide something tomoorrow but will need to put som ereal efforts from then on.
Ben

p.s: regarding the tubes.i'm waiting to hear my first tube as well what u with u guys touting its ability to transform and take u into a whole new world of stereo performance. now, i'm more than eager.

benks....

you must hear tubes, they sound good and look cool as well.

manek.

Benks didn't you listen cadence tubes at AP and the oh so beautiful glow from the tubes will make you go weak at the knees.......I felt the sound was in air....and soothed my ears which is tortured from the Noise pollution in our city.... but way too above my budget....

sub boss.... good tubes are expensive, no doubt but one has to save up for them and then buy them....and once you do there is no turning back to SS

manek.

ok guys,
i'm sorry if i have wasted ur time on this post.
hope that this is the end of this thresd.
maybe i need to curb my postings for a while.
so , i will no longer be taking part in this forum, atleast till my project and my seminar is complete.
i will keep in touch with u guys on the personal level.

PM me and i'll check it up on my mail.
those of u who have my nuber, feel free to call.
anyone wanting to drop by for a listen cal me.
and mohan, call me and we'll setup the time and date for my Nad and ur Klipsh to get together.
its better this way as i can concentrate on my career for sometime.

thank you,
and cheers,
Ben

p.s: thanks to big_ears and Manek for everything.
u guys have been very supportive.

Hey Benks,

You don't have to take jibes personally!

Do cut down on the time you spend on the forum for a while, if you think it helps you in concentrating on your career, but don't give up altogether.

The success of such fora is dependent on the cross-interest generated between members, and, unless I am very mistaken, your thread has evoked interest substantial enough!

Don't worry, keep posting, life is to be enjoyed to the hilt and too precious to go through wearing blinkers.
