I'm interested. Just trawling through all the posts to see if support for multichannel operation with individual channel trim for active speakers with BPPBP ended up being supported.
Individual channel trim will double the number of relays.
At this time Maya offer individual volume per input, not channel.

Tibi

Just put your name on the google spreadsheet.
Maya - Group Buy registration 2018 - Google Sheets
For example I have added your name. Than you need to mention what you need to have on display power on, instread Vicol Audio. For example "Koldby Amp".
Max 16 characters.
Also you need to mention display color.

Tibi
Thanks I must have overlooked that collum. Is that incl. the Hans board? and what are the shipping to EU country. You only have price for Europe Non EU. Maybe it is Europe incl. non EU ?
Thanks for observation. Hans VoICB is included in MAYA BPBP price.
I have added shipping price for EU - 22 euro.

I should note that it doesn't require a doubling for active speakers. Imagine a 3 way setup with two each of woofer, mid and tweeter. The trim would be on on a pair of channels so one board for woofer, one for mid etc.
I can do the trim in DSP so it's not a deal breaker and will add one chunk of functionality I need. I will think this over.
Planning on using this with aksa lender pre, with a phono stage in same chassis. Possibly with tone controls also. An ambitious project for me, it will be a while before I get to building it, but this Maya would make it very nice.
For those who subscribed till now, Maya units are ready. Still few things to tune on firmware.
Standby moving dot was implemented - will publish an youtube link shortly.
I'll start to collect money after 15June and ship shortly after.

The display is 16 x 2, with a 16 character limit on the custom name, will the second line still read "Vicol Audio"? Or will it be blank?
Blank or whatever you want to have. No Vicol Audio on display.
Taking in consideration that I have to modify source code and compile for each order, please note that this is one and only group buy that will offer this option.

What I wrote will fill the first line, 16 characters including the spaces, I edited on the spread sheat as it was more than 16 characters. Thank you for the quick reply.
If there are more than 16characters I'll split in two, or you may add // to indicate me where first line end and second start.

Alright, I re edited the spreadsheat, hopefully I did it correctly, thanks for the clarification.
Tibi,
I have a question. I subscribed for Maya Balanced.
Later if I changed my mind and want to use it with BPBP can I use it changing the firmware (provided I have Hans VoICB PCB)?

Hi Tibi, Can I ask a few questions?
Can I still add a second line to my display text: LABFIVE // PREAMPLIFIER
So LABFIVE on the first row, PREAMPLIFIER on the second row. Can both be centered?
This custom text is gone when we install new general firmware in the future I suppose?
The Maya balanced is my main part of the preamp. I may or may not add a balanced line stage after Maya in this chassis, but I will not add a power amp in the same chassis. So, my idea is that I won't use the speakers relay/delay (and also not the softstart). I suppose the display will still show 'Connecting SPKrs' right? Is there a reason why I should use the speaker relays in my situation? The speaker relays are suitable to switch balanced output?
I suppose I can easily change your two buttons for 'on/off' and 'select' with a bulgin SPST-NO, right ? I want to have the on/off bulgin with blue led like my other equipment. Is there a place on the Maya controller/display board where I can get some power for this bulgin button led after turning on?
Do you possibly have a drawing in front panel express (FPE) of the oled display and the IR receiver ?
Thanks in advance!

Hi Pieter,
Yes you can add one more 16 char line. Both can be centered.
Yes, this custom name is lost when new firmware will come. But at this time Maya is a mature product, we are working to produce documentation and improve mobile applications. I'm confident that you'll be happy with current firmware.
You can change in settings speakers delay to a very short time.
In case of tube preamp, you still may use speakers relays to disconnect output during power up. Same in case you have a preamplifier with high DC output.
Speaker relays are not suitable for balanced output.
Maya have two push buttons, one for power and for menu selection.
Bulgin SPST-NO is not good for this. You may use a nice push button for power with blue led.
You may use one speaker relay to get led light on power button. Or you may use Soft Start relay for same function.
I'm not familiar with front panel express, but a FreeCad front pannel is available at vicol audio : MAYA - world best stepped volume attenuator
