You could see how much John at Orchid would charge you?
Takes the fun out of it of course...

Ignore the post count, I have no idea what I'm doing...

True, and at least I'd be sure he'd design it properly... But the fun aspect would definitely be a loss...

Stereo balanced input - (X32 control room outputs)
Stereo unbalanced input - (Logitech BT receiver)

The details aren't entirely clear from the manual, and the block diagram indulges in a fair bit of 'artistic licence', but it appears that the BKP is actually unbalanced throughout. It appears to ignore the cold leg of the inputs completely, and the outputs appear to adopt an impedance-balanced approach, although its hard to see how that would work reliably given the inherently variable source impedance of the volume control.

That's not to say that being unbalanced won't work -- it obviously will and does -- but it could lead to oddities...

BKP features not required on custom box :-
Dim

I wouldn't be so quick to dismiss the Dim function. When using a conventional pot (rather than a stepped attenuator), channel tracking is inherently poor at low listening levels. Using a Dim switch extends the useful working range of the control downwards by 20dB which is very useful for late night working, checking mixes at low level, and for answering the phone or having a conversation without having to tweak the volume knob.

Dim is, I believe, easy enough to implement so I will draw it in the schematic even if I don't build it into the first version.

Review, Pilot now set-up, it’s completely transparent, it works, review over.

Sam, the BKP is indeed flawed, the input resistance of the ring input is low at 1k and can therefore cause distortion with some sources. As you say, the output is not even close to balanced but AFAICT there is a 'cold' signal.

Other than those flaws, the box works very well and if it seems to satisfy your requirements I would suggest you get one and simple make NE5532 buffers for the inputs and a pair of symmetrical outputs ? The LM4562 will be even better, lower noise and greater drive capability though I doubt you would hear any difference.

Lot less trouble than a 'New Wheel'?

Dave.

Think of how many ads we could get in the mag if all my reviews were that short... :bouncy::think:

I’m always here Hugh, I'm looking forward to doing a one line review of the Behringer/Neve 8068 reissue.

NO!!!! Many are too short as it is. I cannot think of it now but there was a review of something quite high end and complex last year that was dismissed in less than a page.

Might I have the temerity to suggest "quantity" often triumphs over "quality"? Or, if not "quality" certainly 'depth'? And, compared to many 'skinnies' I buy occasionally, SoS magazine is STUPIDLY cheap! Another quid is surely justified especially if it means reviewers can take just a bit more 'time'?

Sometimes there’s not a lot you can say, beyond it meeting certain personal requirements, and it sounding sort of "OK" and most gear these days "is" sort of OK there aren’t any real turds, do you remember those "stereo" radios in the 70’ that were just one speaker with two cardboard tubes going to a couple of fake grills? we need more stuff like that to liven things up!

Surely Sam would just send you more stuff to review? ;)
