Kopul PDI-40 Overview

  • 1Description

The Kopul PDI-40 High-Performance Passive Direct Box lets you connect an unbalanced, high-impedance signal to a balanced, low-impedance input. It is most often used for plugging a keyboard, electric guitar, or electric bass guitar directly into a mixing console's microphone-level input. The PDI-40 can also be used in DJ applications for converting unbalanced +10 dB DJ mixer signals to balanced, line-level signals. This allows you to connect your DJ mixer to a mixing console and cuts down on noise that can be picked up in longer cable runs.

For live performance and recording applications, the PDI-40 features a parallel output for connecting your instrument to an amplifier, while simultaneously sending signal to the mixer. There is also an attenuation switch to lower the signal input by -20 or -40 dB, and a ground-lift button to minimize hum and noise caused by ground loops.

    Kopul PDI-40 Reviews

    High-Performance Passive Direct Box is rated 4.9 out of 5 by 8.
    Rated 5 out of 5 by from Well built I use the Kopul PDI-40 for live gigs and in a recording studio. It is a well built piece of equipment. Metal casing with all the ins and outs I need. It is quiet, with solid ground lift and attenuation switches. There are certainly more expensive and loaded boxes out there but I cannot imagine that they are any better put together.

    Rated 5 out of 5 by from Well built and clean sound I never expect this would be a great product. The brand was never heard of. Works flawlessly and built like a tank. I even use it to connect a laptop sound to the main mixer. I just have to use an adaptor from 1.8 to 1/4 then xlr cable to the mixer. Now the question is how long will this last? Overall it's a great product from Kopul and the price was perfect.

    Rated 4 out of 5 by from Just what I needed I am a keyboard player that needed a good, reliable direct box for live gigs. The price range of the different passive DI boxes is staggering. I read a lot about what the different boxes did and what users had to say about them. I ended up going with these -- the fact that they were on sale was a nice bonus -- and they do just what I needed.

    Rated 5 out of 5 by from Just what the engineer ordered! This direct box worked perfectly, meeting the needs of a guest musician at my church. It interfaced perfectly between the output of her guitars electronic effects generator and my mixers microphone input.
