Kofi Annan in: "Seven-Pound Mono Amp"

Kofi Annan · 23rd November 2006, 06:28 PM

Finalized a seven-pound mono amplifier yesterday. Loud, LOUD L O U D sound for a mono amp and no distotion whatsoever. Its very small-- fits in the crook of your arm-- but it does get awfully hot.

Any advice on further modifications to get the gain down would be much appreciated. Just can't seem to turn it down low eneough to avoid ear-splitting volume levels.

See for yourself:

There's something of a squawk in the upper midrange.

Heartiest congratulations! If it's your first, I can break the news to you: the days of sleep are over.

Congratulations to a great piece of work!
Hope you had plenty of fun "building" it!

yup definitely not (yet) a DIY project.

be advised however, that the unit's power consumption will increase over time - and if you think it's loud now, wait until it's fully broken in (18-30months)

congrats

congrats!

you'll certainly get used to loudness and efficiency of this class.......

pinkmouse · 23rd November 2006, 11:01 PM

Congratulations!

So how long before you go for the 7.1 surround sound experience?

Just be glad you only 'built' a mono-block.

If you ended up with a stereo unit, there would be even more cross-talk to contend with.

Congrats, buddy. Fatherhood is a wonderful thing: be faithful to it.

I expect the damping factor needs to be corrected several times
a day.

Congrats Kofi.

When are you planning to expose to soldering gun... and i guess in 15-18 months you'll need a new Mac so the younin' will have their own.
