Building a DIY 5.1 Audio Video Receiver – Part 5
So far I have finished bringing up 4 of my 5.1 speakers in my DIY 5.1 AVR project. If you missed, check out part 1, part 2, part 3 and part 4 of the series. Next I wanted to bring up my sub-woofer. Since I have an active sub-woofer, I did not need any amplifiers to drive it. I just need to connect the output signal from my audio source directly to the sub-woofer input. But there is a catch. If you connect the audio source directly to the sub-woofer, the sub would be wasting a lot of energy which may heat up the driver and may damage it. Moreover driving the sub with all the frequencies will give boomy muddled up sound. So we need a low pass filter or a crossover.

Building a DIY 5.1 Audio Video Receiver – Part 4
As I mentioned in my last post, after measuring the frequency response and testing the TDA 7498, I decided to buy one more. The board I bought earlier did not have the right LC filter for a 6 ohms speaker. It was designed for 8 ohms speaker. So I decided to use that board for my rear surround speakers which were also 6 ohms. However, it is fine to have a slightly poor quality amp for the rarely used rear speakers.

Building a DIY 5.1 Audio Video Receiver – Part 3
The TDA7498 class D amplifier board that I purchased to power my front speakers was working great. The audio quality is at par with what my Pioneer 5.1 AVR delivered using class AB amplifier. I could not tell the difference in audio quality. None the less, I wanted to make sure the quality is really as good as my ears led me to believe. Enter a function generator and oscilloscope to make sure the frequency response is satisfactory over the range of audible frequencies (20 Hz to 20 kHz).

If you did not read part 1 of building a DIY 5.1 AVR, I suggest you start from there. Here is some important points from my previous post --

Building a DIY 5.1 Audio Video Receiver - Part 1
Alright, you already know the story of my electronics going puff during a power surge. One of the electronics that got burnt was my unnecessarily expensive Pioneer 5.1.2 AVR. The reason I put emphasis on unnecessary is because I rarely used all the features of the device. Don't even know why I spent all the money :). After it stopped working, I opened and checked everything that I could figure out. But I didn't notice any obvious problems. The AVR just boots up, turns on the amplifier relay and turns off. Since it failed during COVID lock down, I couldn't do much about it.

Tax Filler Script
The Indian tax filing has become even more tedious now. Going forward, starting from assessment year 2020-21 (financial year 2019-2020) one needs to report each and every equity redemption that results in long term capital gain in Schedule 112A. It used to be optional last year. Instead of reporting every transaction you could just report the aggregate value. But it is not optional anymore. This increases the burden on the tax payer especially if you have made a lot of small transactions.

How And Who Should Pay Advance Tax
I just payed my second installment of advanced tax, so I thought I will write down the procedure. It will be like a reference for me in the future and might help some one as well. It is actually a pretty simple process that does not really warrant a post, but here we go anyway.

The Sweet Spot: Comparison With MMM
Recently Mr. Money Mustache (MMM) wrote a nice article on finding the sweet spot as applicable to various things in life. For example, a successful tech career's sweet spot is when someone has worked for 10-15 years and has accumulated a few million dollars (in the US context). The "too less" side of things is when the person is earning $15/hour. The too much side is when they have accumulated tons of wealth but at the cost of 40 years of stressful work.

My Corpus Reached All Time High And I am Worried
Just recently, my corpus has reached an all time high. I thought we are in the middle of a world wide pandemic. How come the markets don't seem to care? Agreed that I don't understand markets, but still, this is completely unreasonable. Various indices and stocks in India, as well as in the US, are hitting all time highs. But the economy is hurting. Where am I going wrong in my understanding? Well, there is nothing new happening really. Mr. Market has always been manic-depressive and probably will continue to be that way forever.

Franklin Ultra Final Payment From Vodafone Segregated Fund
Yesterday, Franklin Templeton announced that Vodafone Idea has made full payment of the principle along with interest. If you recall, a few funds from the AMC were holding Vodafone Idea papers which were downgraded to junk. As a result, Franklin has moved those papers to a segregated fund. Franklin already made a partial payment last month after it received interest payment from Vodafone. Now the AMC will be paying out the full amount from the segregated funds.
