  • 4-ch Passive Instrument DI


The PDB4 is a four channel passive direct box that features four quality fully transformer isolated direct boxes in a 1U 19-inch rack mount chassis. Inputs and outputs of each of the four channels are isolated to maximize channel separation. Transformer isolation on each output helps to eliminate system ground loops. It is a rock solid, roadworthy interface for connecting outputs of electronic musical instruments (or other audio sources) to the balanced inputs of mixer consoles and other balanced audio products. The PDB4 also allows connection of a music source to an instrument amplifier while simultaneously patching it to a mixer.

There are some reviews about noise issues with this product. I'm running this in my bands compact live rig and things are very close. Even have a MacBook charger right on top. I don't have any noise issues and all my outgoing Di's sound great. $100 each? WORTH IT. Read the manual, -20dB for line level input. 0dB for instrument level input.

I use this to run a 4-channel mix for my Alesis Strike Pro SE on stage. Has worked flawlessly! Brand was recommended by one of my guitarists. I do not regret going with it. You can spend more on other brands. But, why?

This box is durably built. Each channel seems to be consistent. Probably best suited for live application. Levels are on par with typical entry level DI's. Excellent Value.

Great price and great product. It helps keep clutter on the floor from piling up. I bought 2. 2 rack spaces and 8 direct boxes. I'm a happy camper. It's way cheaper than buying 8 d-boxes.

This unit is a perfect solution to our church's need for an ever present DI input solution. Whenever we needed a couple of DI boxes to accommodate a particular necessity for the Sundsy morning worship service, we'd akesyd be one short. The single boxes would either get misplaced or "walk off" in someone's gig bag (eventually they'd be returned, but weren't present when needed). Now we have four dedicated DI channels on the stage buss going back to the board. As it is passive, there's no need to plug it in or flip an on switch. The sound quality is more than adequate for a live application like a Sunday morning service and as its attached, it can't "go on a walk-a-bout".

This device works as advertised. It works well for my particular use case of eliminating problematic ground loops in unbalanced line-level signals.If my intention for this device was to transform between instrument-level and mic-level I probably would've sent it back as it seems very prone to picking up noise even when just using it as a "cable" by plugging an instrument into the input and an amp into the THRU port.I was able to get rid of those problems by improving the shielding, but I would've preferred just spending a bit more money on an appropriately shielded product instead.

Nice unit. More convenient than using individual DI boxes.

No es súper robusta, pero funciona para estudios de grabación donde no necesites moverla constantemente

I use two of these for connecting multiple synths and keyboards into mixers. These will save your synth if the mixer, or venue wiring is not properly grounded. For the money, they are really good and work well. I can't tell the difference in sound reproduction with it or without it, but I get piece of mind knowing my synths won't be used as a path to ground when someone hits the phantom power switch....

Perfect di for live. It's a passive di , not required any batteries.

Works well. I don't like the ground lift switches being on the back. If you rackmount this, it is hard to access the switches. Other than that, great cheap fix for my studio.
