Ampeg V4-B (2016): no signal from preamp out / DI

[Kevsy71]

Hi all,
My Ampeg V4-B works great into a cab, and I thought I'd try a DI recording. 

Chain: P bass -> 0dB input on V4-B -> DI out -> Focusrite Scarlett 2i2 'Line' input. My speaker cab was connected.

Nothing registered at the Scarlett (tested with other preamps, and working fine). I heard the bass as normal through the speaker.

Tried taking 'Slave out' and 'Preamp Out' to the Scarlett, again nothing.

But: when I feed another Preamp into 'Power Amp In', then the DI works.

Any ideas please? It's as if the V4B preamp->power amp chain is working fine for speaker output, but not for the preamp->DI/Preamp out/Slave out circuits.

Cheers!
Kev
