617-8a xo

[magnarc]

Greetings from a still warm Sydney...

I'm getting a number of 617-8As together to put into service as cinema surrounds for a film fest, and have discovered two have stuffed XOs, well the caps. I've been searching high and low for a schematic for the XO so my more tech orientated colleague can fix it. Has anyone ever seen or got one?

Thanks!

Nat

2-way, 1500Hz, 12dB per octave each band. Easy peasy. See 617-8a brochure on AltecPro website.

Cheers, Marshall.

Thanks for the info, but I need the cap values if poss.

I've never seen a posted schematic.

There's about half a dozen out in the barn. I will open one to see if they are marked

Caveat: moving fast is sometimes an issue, may take a day or so

Maybe i can save the old fella a trip to the barn.

The one i'm looking at appears to have 10uF and a 2ohm resistor in series with HF, and 16uF across the LF.

Good thing you posted when you did. It was only an hour and a half, so I had just made it to the kitchen...another 4 or 5 hours I might have been outside...
