Setting up PA system: line arrays, class D stereo amp, 31-band stereo EQ, mixer, and 4 condencer microphones. I made frequency response as flat as possible using my usual technic of acoustic feedback, so people can move and speak freely without thinking about microphones.

Some snacks in the same room provided by other volunteers...

Volunteers organized everything very well!

Linear Sytems brought some samples of devices they produce. Particularly, low noise JFETs to replace devices that Toshiba does not produce any more.

Other people brought lots of parts to give avay by lottery.

...including 10,000 MicroFarad capacitors, 250 Volt!

Image


...power FETs

Image


...and many speaker drivers!

Jan Didden brought from Europe bunch of new books and magazines and very interesting device. It sensed head position and adjusted stereo balance, so sound sources were always localised in the same places.

New Linquitz dipoles sounded fantastic today!

I approached him and said Hello from Russian DIYers who bck in 1980'Th copied his active crossovers and EQ.

He said that I was the 3'Rd one who said the same, but was obviously pleased. Smile

Nelson Pass started his speech, and we went to walk. When we come back he was standing in front of the public speaking softly, a microphone behind his back... I moved one microphone in front of him, so at least the end of his lecture was audible...

Jim AKA 6L6 said short speech about audio community and support of each other. Later 2 guys approached me asking where is he, they want to join the community and get some support! Smile

Funny, but I took no pictures of Scott Wurcer, because I was listening. Particularly, he brought very interesting idea about getting polarizing voltage for condencer microphone capsule using optical devices that are being manufactured for solid state relays. But I took a picture of Linear Systems' representative Paul Norton!

Here you can see Burning Amp EQ, such curve was needed to make frequency response almost flat for higher sensitivity, so people could speak on the distance from microphones. However, when microphones were left behind they were almost useless...
