Hi,
I just built the BANK but it doesn't work.
The LEDs work fine but I actually mesure 9V DC on the Outputs...
Is there any shematic of this module available anywhere?
Cheers

I had to do two repairs on this project:
1) For R86, as I lost the component or maybe forgot to buy it I DIYed a resistor in series who's value is 119.4k instead of 120k
2) C114 is directly soledered to the neighbouring pin as I destroyed the corresponding place of the PCB where it should have been soledered.

Does anybody see anything wrong?

The Gerber file and some help would be very welcome.

Has anyone been able to get access to a schematic for the Bank? I know it is based on the YuSynth module, but it would be easier to debug problems if a proper schematic is available. I also have issues with the LED jacklights, which aren't present on the YuSynth module.

Bank is based on another design detail of which can be found here.

I just bought one of these second hand and am also struggling with how low the output level is on this thing.

Listening to the mix output with input level at max, HP and LP fully open and bands set in the middle, the level drops 16dB through the high gain input and 33dB through the low gain input. If I crank my mixer to compensate the sound quality is a fair bit worse than the input signal. I assume the freq gain pots are set to +- from unity in the middle? I feel like it's pretty unusable as it is.

Any help much appreciated.

No, the frequency pots only cut (apart from the little resonant peak the filters will introduce) as far as I know. The easiest way to increase the output level is probably to increase the gain on the output buffers, that's RN1, R85 and R86 in Yves' design (there's no schematic for BANK so can't tell exactly which ones correspond).

I have recently purchased a BANK on eBay. All is good but the low and high pass pots do very little. The low pass is noticeable but rather weak but the high pass is very difficult to hear any difference. Compared to videos I have seen of other modules (such as the Behringer Filter Bank) there should be a noticeable difference (especially with pink noise).

Is there something wrong or are these filters just to tweak the sound?
