Well I have not put it into regular use yet but everything seems to work properly and very well. The relays are much quieter than the Maya relays. I still have some work to do though. My chassis contains a phono preamp and a three way crossover as well. The Maya controls power to the other components and I have a few issues to resolve with that. It should by ready in a few days.
A big THANKS to you Hans for the design of these add on boards for the BPBP. Also Tibi and Dan at Vicol Audio deserve credit for making this possible.
Thanks, Mike
Thanks Dan,
To all:
This Firmware 1.1 should be the universal version for all BPBP users, with just 2, 4 or 5 inputs and includes the software that enables glitch free volume switching.
Hans
Hi Hans,
You mentioned 2, 4 and 5 inputs (?). There are some 6 inputs boards waiting for the VolCB and Maya, mine included
Maybe you mean 6 inputs?Thanks and Regards,
Enrico
As Hans explained to me in an email there are also 6 input board.No problem... Better I asked for
Thanks Hans for your amazing support
All the Best
Enrico
For this and only this , here the attached firmware .
Please test and feedback.
Thank you and best regards.
Version 1.2 can indeed be used by all variants of the BPBP with either 2, 3, 4, 5 or 6 inputs.
The point is of course that when you select an input that you don't have, the system does display this input on the display.
So when you have a 4 input board and you select input 6, this results in silence.
With the 2 input version, you can go from input 1 to input 2, but when selecting input 3 to 6, you go simply back to input 1.
But I do not see this as a big problem.
After having discussed these points, Dan proposed the following:
I will implement in the future a new firmware truly universal :
in the settings I will implement 2 new sub routines
- one in which the user can set a number 2,3,4,5,6 depending on how many inputs really has
- one in which the user can set the max gain of his BPBP to let the gain on the LCD match the real gain.
Both setting will be saved in a config file in Eeprom and loaded at power on.
But it will take some time , at least 1 month .
The point is, are those not able to load a new firmware version willing to wait another month, or shall everything be shipped by now with Firmware 1.2

Hi Hans, I would like to see the real attenuation on the display because I can feed the preamp with +4 dB. To wait one month more doesn´t matter. But if other people can´t wait, I will be able to live with the existing firmware.So do what you like to do and many,many thanks for the great work you are doing.
Will be soon. Some people still doing some testing. I'll post here when I have an update.

I have good news.
Received the Maya controller plus VolCB and 4 input board last week.
After having installed firmware version 1.2, I have tested all functions and was impressed. Everything worked the way it should work, including the glitch free volume control and the remote control.
One thing needs some further explaination:
The Maya mute function is realised by deselects all incoming channels, so with the 4 input and the 6 input boards this will work perfectly.
But for a standard 2 input BPBP the input selection is with just one relay, selecting either one channel or the other.
So the Maya mute function will automatically result in playing one of both channel.
It is up to Tibi now whether he wants to deliver all outstanding orders with version 1.2.

Excellent! (fancy putting up a photo or two?)
How did you feel about the volume level reading?
Good news indeed! Thanks Hans
If the version 1.2 cover all the various configuration should be useful to have it already installed
Best Regards,
Enrico
That is outside the scope of the Maya Controller.
There is however relay K3 on the BPBP that can short circuit the output.
With just 2 channels you can use this relay to get a mute function, simply by pulling the base of T3 to V- with a switch.
A more complex solution is to connect an NOR port to channel 1 and 2 of the PCF channel selection chip and let this port steer a relay that shorts the base of T3 to V-.
In that case the Maya Mute works also for the 2 channel version of the BPBP.
