Need a 4 way electronic crossover

I have a 45 year old Sony electronic crossover (model TA-D88B) which has been great and have owned it since 1978 but am having a problem with it now.  In the event I have to replace it can anyone recommend an excellent electronic crossover?  I've seen the Marchand line but it gets mixed reviews.  I need a 4 way system (sub-woofers, woofers, mid high horns, and tweeters).

Thank you for any advice- I did not know where else to post this so put it under amps/preamps.





suggest you find a local electronics repair shop and take it for a service/restoration. you may find it can be repaired easily. 

Its definitely worth saving. and after a restoration probably sound like new. 

right now the state of the art for analog crossovers is the CS Port ACN400. but it’s not cheap. if you want a cheap one it will likely need to be digital, or a cheap pro-audio product from a web site like Sweetwater.

I believe this would work.

Supports all standard crossover points and slopes + has built in EQ which is very handy for taming bass modes.

Thank you all for your advice.  I'll look into the CS Port and trying to find a good repair shop.

I had a Marchand crossover and it was an exceptional piece.  Well-built and sounded great.

I have not seen mixed reviews for Marchand.  Occasionally used ones come up for sale.  New are 800 to 1000 approx.  

There is also a new brand that advertises quality parts used.  The name escapes me.  They have 2 models priced at $599 and $799.

I would also fix the old one, if possible. 

I am currently using a Marchand and it works as advertised, it doesn't do anything deleterious to the signal.  Having said that I would attempt to have the Sony rebuilt simply because you obviously like what it does.




Thank you all for your responses, very helpful.  I will try to have my Sony crossover fixed as it's a great piece and would like to keep it.  If not able to do so I will look into getting the Marchand.
