Team TalkBass: I've got a new GK 700RB-II and finally got around to testing the DI. It works fine with the button in the preEQ position, but in the postEQ position there is no audible output. I would expect some volume difference, but the sound goes completely away. EQ is set full noon with Boost at 3:00 o'clock and Woofer at noon. Any ideas on other things to try? I've made various adjustments to the EQ and input stages with no luck. Also reached out to GK support via email without a response (two weeks ago). Thanks.
