Hi everybody,

does anybody have the schematic of the card for the 4355, crossover 290 Hz/ 18dB?

I ask for a friend.

Thanks and regards

Dieter

Hi Giskard,

i have a new question:

in the manual for the 5235

http://www.jblproservice.com/pdf/Vin...5%20manual.pdf

Jbl wrote that for the 51-5145 card R1 is 5,2 k ohm.

In your post you have a copy where R1 is 6.2 k Ohm.

What is right?

Or i am wrong?

Please help me and my friend.

Best regards

Dieter

Good eye Dieter!

Here you go:

Looks to me like the 5234A manual is right and the 5235 manual is wrong.

Looks to me like the 5234A manual is right and the 5235 manual is wrong.

Yea, looks like a typo. Besides the curve (thanks, Giskard!), all the 18db/Octave cards have R1, R2, and R3 of same value, both in the 5234A manual (5234A Manual - Link) and in the 5235, except for that 290 Hz card.

Another typo for the record books.

"all the 18db/Octave cards have R1, R2, and R3 of same value"

Yeah, except when you're building the 4430/4435 card which also uses the 18dB/octave card.
