Suggestions for passive DI box

[Gunsfreddy2003]

Evening all,

 

Looking for suggestions and recommendations for a good passive DI box for use with bass - I've looked at the Radial JDI but it seems quite pricey for a simple DI box.

 

Happy to hear any other suggestions and alternatives please.

 

TIA.

Orchid DI - simple cheap and works well

I'm a big fan of Palmer Passive Di boxes. They are very well built and sound great. I use the Wipper.

Thanks for that - I had opted for one of these at lunchtime:

This one is a lot cheaper than the JDI

Definitely. Either that or a Radial ProDI or JDI secondhand. 
 

I have the Pro and picked it up on clearance for £49. This was a few years ago, mind.

Though - not reading the title of the thread - orchid is not passive

It can be phantom powered.

Still not passive and phantom isn't always available on some PAs or can't be activated on a per channel basis, which might make some setups difficult to cable.

 

Passive DI boxes are great because you don't have to worry about issues like this or batteries going flat. hey can sit in your equipment bag until they are required and you know they will be fine. I have 6 channels of passive DI I take to gigs for my band. That's one for everything we need and a spare. I wouldn't contemplate an active DI device unless I was in charge of the non-battery power for it.

On the other hand Active Di and phantom power has been a solution for the last half century 🤣

Active DI Boxes powered by phantom power are fine if it's for your own PA. For use with an unknown PA where phantom power may not be available or may only be activated in groups of channels where it may not be appropriate for some of the other equipment connected, it is safer to use a passive DI box.

 

All the problems I have encountered with signals from DI'd equipment not reaching the mixing desk have been down to active DI boxes. Replacing them with one of the passive DI boxes that I always carry has sorted out the problem every time.

If you shop around a bit you should be able to find the radial ProDi or a stagebug SB2 secondhand, that's what I did, managed to get a pro and 2 stagebugs used for the well under price of a new JDi (i think about £50 each?)

 

the build of another pedalboard means i'm on the lookout for another SB2 as well

Hope you don't mind me piggybacking your thread Gunsfreddy.

 

If I have a passive p bass, but run through a Cali 76 18v comp pedal, should I look for a passive rather than active DI box? Thanks

It shouldn't make any difference. The whole point of a DI box is that it takes instrument and/or line-level signals and converts them to balanced line for the mixing desk. Whether the DI box is active or passive should make no difference to the impedance it presents to the input signal.

 

IME a good passive DI is slightly more reliable since it doesn't require a power source or phantom power which may not be available, and doesn't cause problems when connected to equipment with non-standard earthing.
