Need good pics of BXi1608

need good pics of the location around the phase shift pot, and the bass boost pot.

Perry Babin · 16th February 2011, 06:17 PM

I have photos. What specifically do you need to see?

807tubenut · 16th February 2011, 06:24 PM

the resistor and cap values for the bass boost circuit, and the phase shift circuit, I'm adding bass boost and phase shift to a AQ1200

See if these are good enough. Let me know when you have them so I can pull them off of the server. View them at 100% to see the fine detail.

and while I'm here, I noticed on the driver cards out of a few korean amp's, there is a spot that looks like it's for a switch, says something to the effect of "ON(cant make out this letter/number)9v:OFF

got any idea what that's for? I was pondering it as being a low/high voltage override of some sort.

Which amps have this?

807tubenut · 16th February 2011, 07:20 PM

got the pics, thanks Perry!

The Hifonics brutus series that iv worked on, has the card, this aq1200 (being the same pcb as the BXi1608) has it, and a few others iv done. Here is the card.

I think I saw a transistor in that location in one amp but I'm not sure. Is it possible that it was to be used instead of the adjacent transistor?

If you can name some of the other amps that use this board, I'll see if I have photos of any of them.

It could very well be a transistor location, but not for the SMPS driver section, looks to be part of a voltage divider, Once I get this AQ back up and going, ill get some readouts on the pins.
