2016年10月18日 · I have a dbx 386 dual channel tube preamp. It was out of service for some time and when I recently put it back in the rack only a couple of LEDs turn on. On inspection it seems that the larger of the two transformers supplying power to the PCB has transformed into a Gandalf No-Pass Filter ("None shall pass!"), i.e. voltage in to the transformer ...

2008年6月25日 · I'm trying to connect my dbx 386 tube preamp to my E-MU 1212m sound card using S/PDIF. I've bought the proper cable to use and connected it from the dbx 386 S/PDIF out to the 1212m's S/PDIF in. I've messed with the session settings in the 1212m's Patchmix, but I still can't get any sound on my computer to come in from the S/PDIF in.

A friend gave me a broken 386 and after going though it and getting it working, I am wondering if it might be wise to add a transformer on the input. I haven't traced it out myself to confirm Bushy's trace of the circuit but it looks like its using a 4580 op amp for the first stage of amplification. This would seem to give us questionable CMRR.

2007年3月9日 · Im alittle torn between two preamps right now, which are the dbx 386 and the Aphex 207d. both of these are tube, which doesnt matter if they are tube or solid state, the idea is to get the best out of my PreSonus fire interface by adding two additional mic preamps via S/PDIF and also considering using the preamp as a front end for vocals.

The dbx 386 Dual Vacuum Tube Preamp with Digital Out is a dual channel tube microphone preamp that comes with the additional capabilities of digital output. With the included digital outputs, the unit is the perfect companion for recording and tracking vocals, or any applications needing microphones, both in the analog and digital domain.

If I were to send the the signal from the 2-610 with the balanced XLR outs into my dbx 386 Tube Preamp balanced XLR balanced ins, then used the S/PDIF out on my dbx into my Emu-1212m sound card, would I still be able to get the Universal Audio 2-610 tone? or would running it through the dbx 386 kill the tone or possibly make it better?

NEED HELP with broken channel on dbx 386. bentothesmith 5 June 2012 I am not experienced in this area, but there are no places within a 2.5 hour drive to take this thing to.

iv'e had my dbx 386 for some time now and i am still having trouble getting it to sing to my e-mu 1818 interface. there is no input in my S/PDIF dsp channel. Cubase clock source is set to S/PDIF but sample rate changes from the dbx don't affect the rate in cubase.
