I have also used 6 transformers on the output, or my my current unit that has 4 transformers and 2 stock outputs. No problems at all with levels, I get 2V RMS I think.
Scott, how are you controlling overall volume?

I am afraid there are no tests or suchlike for this unit. I bought it blind, hoping it will work. Luckily it does. Quiet and noise-free..
With great difficulty at the moment! Waiting on the 6 gang pot I have on order. Just experimenting with the digital input, will revert to analogue for the time being. I'm getting better input level with the digital so will go that way ultimately, also means a couple less conversions so must be the optimum way
digital input going red, is this an issue when going from AES3 to spdif? I can not hear any clipping though. Some black tape doing the job well 😀
On digital signals the input VU meters should see red from time to time. As long as the digital signal itself isn't clipped, the DCX input will not be.
I presume all it means is that the input from the CD player is approaching 16 1's or 24 after upsampling? In the end it is what it is I can't see there being any advantage to attenuating the digital input?

The output meters shouldn't be as high, if you have the crossover turned on. Think about how crossovers work. 😉
Yes, it's ok, I edited post above, I forgot I'd attenuated the input, output meters are up where they should be, I've taken xover into account, I'm not that daft, haha. My 6 gang pot has just this minute arrived 😀😀
Have fun with the pot - is that legal? Let us know how well it works. You'll end up having 2 volume controls on the outputs, right? The 6-gang, then the volume on the amps themselves.
I'll be using 4 gangs for the time being with my WAW set up. I'm planning to use just one volume control but may have to attenuate further, what do you suggest?
Thanks for link to chip data sheet. Not a word about distortion.
But I am curious about the how well these devices pan out when implemented. Seems there are a whole bunch of similar (identical?) devices out there.

Can anybody offer some further guidance on buying an electronic ganged 6-channel volume control?
I couldn't be much happier than with my SPDIF coax to Input A and a multi-gang pot output control.

You'd want your amps to have their overall gain set fairly low, I would think. That gives you a better range on the 4-6 gang pot. Have you read the article on gain structure? It could help you understand how to set up things.
Yes, I'm aware of gain structure, I don't use a preamp. I'm probably going to need to connect individual pots after the ganged pots on the amp inputs, is there a prefered way to do this? The ganged pot is 10k log, would similar value afterwards be ok, the amp's input impedance is 22k?
I'm using S/PDIF as input, not having any problems that I'm aware of, quite long runs of any old coax to hand. If there was an issue with level would it be easily apparent?
When using the SUM function to make my stereo subs mono, I'm having to attenuate them both, does that sound right, ie even though it's doing it digitally they are still mixing in an analogue way if you see what I mean?
It is just the sum, like analog if you want.
I found you got to boost the sum if I remember correctly.
I think it was like 6dB.
