Analog loudspeaker management devices

Sorry for my english. I don't know if the subject is misleading.

I am asking for older, proven to be good, FOH gear they don't have to vintage. They can be even "lo-fi" but robust and reliable. Is it called FOH: eqs, x-over and time correction etc? Particulary relating to loudspeaker management and they should be analog. This is not a wanted topic. I'm asking for help from those who know about this stuff. I don't have that kind of knowledge, yet..

I have been thinking about replacing my berry dsp with an analog system. I don't know if it makes any sense. At least i would look cooler : D lots of 1U gadgets.

I've had for a while now a dream of vintage rig with all analog system.

Is BSS TCSs analog? Is there some analog time correction units? Should i make them myself, i know there's most of what i need in ESP-pages.. : ) the sound quality might not be that good hah.

Re: "you won't find Analogue delay units that are adjustable across the range"

You can, although they are somewhat few and far between these days.

The Klark Teknic DN 34, used in delay only mode, is a good example. It has dual "Bucket brigade" delay elements in differential mode to reduce noise.

The BBD IC is the SAD1024, datasheet available here:

Otherwise there are numerous Analog crossovers capable of having added EQ

Edit: add IC type and link

it appears that the SAD1024 IC is very difficult to find, however a replacement which is available could be the MN3007.
Some useful info here: http://music-electronics-forum.com/t23353/

Good luck with constructing something based on these delay ICs. I did some designs and built a number of delay units based on the SAD1024 back in the 1970's, so PM me if you'd like assistance although my memory of some details may be missing!

After reading a few posts about it it doesn't seem to have a good reputation about the sound quality. I understand the difficulties of analog time correction and using such with precision : ) audiomik wrote: Otherwise there are numerous Analog crossovers capable of having added EQ Can you name one? Here's what i was looking about: http://sound.westhost.com/project09.htm of course it doesn't have to be a DIY. Also analog limiters are of interest and i think this could be easily done as a DIY? 6in 6out limiter unit? And one more thing how hard is analog phase adjustment? I'm starting to realize how much these 1U DSPs can do! : D

Is Klark Teknik devices good quality?

Generally yes, bit better than most. I'm bidding on the £78 one, the two cheaper units are good aswell but Im not on those.
