Details
Controls: Per-channel locking ground lift switch, per-channel signal/ground-lift LEDs, power switch, 115V-220V mains selector
I/O: 4x front-panel locking 1/4" instrument input jacks; 4x rear-panel 1/4" input/passthrough jacks (parallel wired); 4x XLR mic-level outputs; IEC mains
Notes: 4-channel, all-triode vacuum-tube DI box; reimagining of the D.W. Fearn VT-I/F design (flagged D.W. Fearn heritage) — effectively four VDI circuits in one 2-space rackmount chassis. All-steel construction. Manufacturer page does not state whether input/output transformers match the VDI's (VDI explicitly cites a custom Jensen output transformer; not restated for 4DI, so topology field left as tube/valve only rather than assumed transformer-coupled). Price $3,400 MSRP per Vintage King search result; not listed on manufacturer site.
