The pictures are too tiny :-(
Its hard to see, but it looks to me, as if the BBF has no FX enabled.

But what looks strange, why do you use XLR 1? in mono (L) and Line IN 4? mono (R) ?

The Kwai is a piano I guess and it has for sure asymmetrical line outputs to phone.

So you can not mix on the BBF symmetrical and asymmetrical inputs, that should be clear.

From the product specs the BBF Pro has:
2 analog inputs AN1/2 for Mic and symmetrical line in
2 analog inputs AN3/4 for asymmetrical line / instr inputs

So, please use the 2 asymmetrical line inputs AN3/4 for the Kwai and best in stereo mode, its a stereo signal.

Ok, misunderstood, so BBF.
Then use Analog IN 1/2 in stereo mode.
And pls see handbook p.8, the comment when you use XLR inputs with an asymmetric connection:

"The Babyface has two analog microphone inputs that can operate as line inputs with levels up to  +12  dBu,  when  set  to  0  dB  gain.  The  electronic  input  stage  uses  a  servo  balanced  design  which  handles  unbalanced  and  balanced  signals  correctly,  automatically  adjusting  the  level  reference. When  using  unbalanced  cables  with  the  XLR  break
out  cable:  be  sure  to  connect  the  'ring'  contact of a stereo TRS jack, and pin 3 of a XLR jack, to ground. Otherwise noise may occur, caused by the unconnected negative input of the balanced input."

is there anyway to increase the gain on AN1 by 0.1 to 0.9 or is it only by 1.0's

The reason I want to increase the gain :

There is a 0.2db difference between the  XLR L =-20DB &  THE INST R = 19.8db in total mix fx .
I realise this is small just thought if it could be adjusted by 0.2 the I could balance out this PITA connection to my kawai.

Anyways like I said it's not even noticeable anyways

Thanks

>2 X Hoser cables / TRS's out from kawai phone jacks to XLR's IN'S AN1+ AN2 ( these are the cables )
>total mix fx - AN1 is set to stereo

It works - however middle C + 1 octave (approx ) either way is really bad ???
sounds like an overwhelming reverb that squashes the tone of the piano notes from middle C outwards either way approx 1 octave .

-So for example if I hit middle c on the piano all I hear is 90% reverb + 10% piano tone > (something is not right )
-When I go 1 octave up Or down to the next C note on the piano it is 100 piano tone ( working perfectly)

(Let me say that reverb sound is what it sounds like - like the tone is squahed to death and can't breath ) best way I can describe it - totally unusable .

Any suggestions ! Also why does it works with AN1 + INST flawlessly ? I think I have a dud snow edition !

1) TRS L only plugged into the kawai ) to XLR L Analog BBF IN
RESULT : same result no good - middle c sounds like a smoker who can't
2) exactly the opposite to :1)
Result :  same result no good

3) swap of both : 1) & 2)
Result : same result no good

4) ok now I wondered something else  !?!?!? When I connect the  (TRS to XLR L  BBF )+ (TRS to TS R BBF INST )> we know it works this way BUT when I disable the ( inst - orange button in total mix fx , leaving only AN1 L now live - AN1 now works clearly - properly as it should !

Why will AN 1 L not work on its own
But when I combine it with INST R I have proper stereo and then when I disable INST in total mix fx I have proper AN1 L ? I am mind boggled

any suggestions what's causing this
