    For anyone that uses a radial jdi have you ever tried the speaker route. I've had mine not to long but haven't ran it in that mode live yet. Actually I've just became hip to this process. Sounds like it might even sound better?

    I have not and only used the JDX that way for guitar with successful results.

    I did it when I had one, and it worked very well that way...

    I have been Countryman 85 speaker DI'd a few times, for my sound the highs need taming at the board, otherwise fine. Since I got my AkgP2, DI begone.

    Just to double-check whether I'm understanding properly, can the JDI take a speaker-level input, or does it just have a speaker-emulating feature that tames the high end some?

    From what I've gathered is this:
    You can run a 1/4 instrument cable from your cabinet (parallel jack) to the DI. You have to first hit two buttons on the DI
    1. -15 pad
    2. Speaker button

    This will send a wet signal to the board and also will engage a feature in the DI that supposedly emulates a 12 driver.

    Have not tried it yet but it sounds worth trying? Might sound better?

    Thanks for that, that was my understanding from the manual, as well, just double-checking

    I just recently bought an AD200, which doesn't have a preamp out or a loop or anything, so it's either be able to DI a speaker out or DI my bass only, and why the hell have a nice amp and not hear it, even in fold.

    It works really well that way. Ground lift, polarity/phase switch, 15db signal pad, all make it flexible too. I've used it a few times to take the speaker out of my 40 watt tube combo to a power amp/ speaker cabinet onstage too. Sounds great.

    The manual doesn't specify either way, but wouldn't you use a speaker cable instead of an instrument cable?

    Just got an email response from Radial confirming it's a speaker cable you use from the cabinet to the JDI.

    Considering a JDI at the moment.

    If it is a 1/4"jack then the signal is carried the same way isn't it? Are they saying speaker cable purely due to the wattage going thru it?

    Well, it's actually the current going through it, but yes.

    Yup. You're just inserting the DI between amp and cab rather than between bass and amp, hence the requirement for the pad, etc. I've used JDI's for a long time, but I've never actually tested one out for a speaker level DI.

    I picked up a JDI when the DI out on my Eden started to get noisy... seemed a cheaper route than the multiple tech visits. I initially used it with the speaker function running it out of the speaker output of the amp with good results but I felt like the speaker sim rolled off the tone too much for my taste. After recording with the JDI both ways i opted for just running it in front of the amp and letting the FOH do any tweaking needed... now i change my stage sound with the amp and just let my bass run full out front which keeps the sound guy from giving me dirty looks when I want more bass on stage.

    I have one and haven't tried going that route. Most guys behind the desk want as flat of a signal as you can give them, which usually means putting the DI between your bass and your amp. The JDI largely sits in the gear bag as my head has a "Pre-EQ" direct out that keeps most sound guys happy, but occasionally they want a box instead.

    It sort of flies in the face of buying a "good rig" when most of the time the house sound wants to bypass it completely and it becomes basically a stage monitor for you, but it gives the sound guy more control. When you give the sound guy a "wet" signal with your EQ already dialed in if you have a frequency emphasized on your amp that really doesn't work in that space, it makes the sound guy's life difficult. That usually means you either get buried in the mix or sound like crap all night.

    If you have really developed a tone that is unique and a solid enough style that a flat eq or the standard "this is what bass sounds like" eq the sound guy usually runs with won't work for you, you need to have that conversation with the sound guy. Sending him a signal that isn't what he wants when he doesn't know why is going to make no one happy that night.
