TW Prudence question

[Raoul Duke]

Greetings all,
First time poster/long time lurker.
Been searching here and reviewing the MOBonTV YOUTUBEs looking for info about the “attenuator” installed in Matt’s original KF Express (Prudence). Not finding anything specific so thought I’d ask here. Anyone know what’s going on under the hood there?

Thanks in advance!
