OVERVIEW

Passive DI gives you level control to tame hot signals from high output instruments.

The SPDI passive direct box from Live Wire Solutions features a 1/4" high impedance instrument input and output plus balanced and floating low-impedance XLR output that ignores +48V phantom power.

Variable attenuation provides maximum input flexibility, while Lift mode severs ground connection between the input and the XLR output. GND mode leaves ground connection intact between input and XLR output.

FEATURES
  • 1/4" high impedance input and throughput
  • Balanced XLR output
  • Ground lift switch
  • 0/-20/-40 dB attenuation switch
  • Heavy duty, all-steel chassis
  • Rubber skid pad
SPECIFICATIONS
  • Weight: 0.75 lbs.

Bought two of these to solve a ground loop problem between a Rocktron tube pre-amp and ADA tube head in my guitar rack. There was a very faint but annoying 60 cycle hum present I had been living with for years and these DI boxes eliminated it completely. My amp is now dead quiet for the first time EVER. BUT -- I did notice an attenuation of the signal from the pre-amp into the amp inputs, even with the DI boxes set to zero on the attenuation pad. About 20%actually, definitely enough to notice. I had to increase the output signal from my pre-amp and bump up the high end slightly to compensate, no problem after doing that. I have not used passive DI boxes much so this is probably a "feature" of the passive design and to be expected. Otherwise, they work great, built sturdy and a great value overall.

The pad sw in my unit was intermittently passing/not passing signal in the 0db position. I fixed the problem by removing the sw from the case and filing the rectangle opening a bit longer to allow the sw to fully lock into it's 0db position. It's cheaply made but does it's job and sounds fine for live work.

Good price, good quality.

Comments about Livewire SPDI Passive Direct Box with Attenuation Pad:

Used this box at our church to interface the audio from a DVD player to the sound system while showing music videos. Has a wide frequency response, bass response is excellent (music videos are a good test for bass response). It's in a heavy steel case with a three-position input attenuator switch and a ground lift switch. Two paralleled 1/4" input jacks and an XLR male output jack. If we need more DI boxes in the future, this is the one we'll get.

For the money, you can't beat this box. It's easy to use and well built. In fact, I am ordering two more units today so that I can have them for live acoustic performances.

Simple. Well built. Effective. Periodically I experience ground loop hum depending on the venue. I keep one of these in my bag of tricks to resolve.

      Awesome Direct Box

      By Dean Rohleder

      from Kansas

      See all my reviews

      Comments about Livewire SPDI Passive Direct Box with Attenuation Pad:

      Musician's Friend's customer support is fantastic! Very fast shipping too.
      Ground lift sw. & attenuator are great additions to this VERY inexpensive direct box. I perform in a very electrically noisy environment and this thing really shields out that noise, both 60 cycle & RF interference is non exesitant.

      I also use this as an interface to plug my guitar into my computer's mic jack. It matches the impedance perfectly & cuts out all the noise even when using a 20' guitar cable.
      Built like a tank. You won't crush this in your Roadie bag. Well built, even has a LARGE non skid pad on the bottom.
      Can't beat the price here either. Only one other that's more inexpensive & it's usually out of stock.

      Comments about Livewire SPDI Passive Direct Box with Attenuation Pad:

      Bought and used 3 boxes when found out our venue only had XLR and we had to wire up an acoustic guitar, bass guitar, and electronic drumkit (instrument cable output). Plugged them in and all 3 worked fine with Ground Lift off and 0db attenuation. Sounded clean. No issues. Only used once so far so cannot comment on long-term durability, but boxes were metal and seemed solid.

      Comments about Livewire SPDI Passive Direct Box with Attenuation Pad:

      Good quality construction, good strong signal, quiet. Great buy for the bucks.
      Attenuation pad is a nice xtra.
      Solid. Metal case, rubber pad on bottom, should last a long time. Use it in my studio at home and to send the output from my bass to the PA and my amp on gigs. Works great in both applications.
      You could pay a lot more and not get anything better.

              This box works great. I've had one for 2 years now & it works great and has always been reliable. I bought this one for a friend that likes mine. It's never let me down yet so untill it does, I gotta call it great. I guess we'll have to see if it will last the test of time, like I said, right now it's a little over 2 years & still going strong.

              Comments about Livewire SPDI Passive Direct Box with Attenuation Pad:

              I really cannot rate this unit at this time. I just bought it and have had no opportunity to use it yet. It certainly is a sturdily-made DI box and I love the XLR ins and outs and the 1/4" ins and outs. The attenuator pad is an extra! Only drawback so far is that one of the four tiny screws is missing that holds the top of the case to the bottom. No problem, even at that.

                  This unit does exactly what I need it to do. I use it to record bass in my home studio. It works great. It changes the high impedance output of the bass so that I can plug into my low independence input on my DA interface. Great product for the price.

                        I bought two of these for live, duo acoustic performances. I spent time trying to find a pair for our guitars that wouldn't break my bank and should hold up and do what I needed them for. I am very impressed with them. I use a ibanez pf series acoustic with a rosette positioned pick up that's removable. It sounds amazing!! The acoustic feel and sound is amazing and still sounds natural through the pa. If your gigging with out one of these and are in the market, buy! I have used these multiple times now for hours at a time and so far I have had no issues.
