Ensure virtually any active instrument in your repertoire gets a strong, noise-free signal with the Heritage Audio P DI One, a passive DI box with a custom magnetic transformer and a balanced, transformer-isolated output stage. With the noise-blocking transformer, you can enhance samplers, keys, synths, and more while eliminating RFI and DC-born noise.

The P DI One offers excellent signal integrity and superior noise rejection thanks to its premium circuit components and gold-plated I/O connectors. The DI box provides a -15 dB input pad for overly hot signals and a ground-lift switch for eliminating grounding loops. The enclosure is constructed from durable 14-gauge steel for complete protection of the internal PCB. Along with metal switches, this DI box is built to last, even under intensely rigorous usage. Input and thru jacks are 1/4" and the output is over XLR 3-pin.

Versatile and Pristine

Being a transformer-based unit, its output is isolated from the instrument and there is a further provision for lifting the ground, as well. An additional -15 dB pad switch helps with hotter instruments and even allows speaker outputs to be plugged into the P DI One. A thru parallel connection rounds out the pack, and all I/O jacks are gold plated and isolated from chassis.

Bring Out the True Tone of Every Instrument

The P DI One works best with active circuit instruments like keyboards, synths, drum machines, samplers, and some guitars and basses, when they are required to be plugged into a PA or recording system. By matching the instrument's output level to a typical microphone level, converting it to a balanced signal and minimizing noise, you can be sure you'll achieve the strongest, clearest signal possible.

Passive Design for Minimal Noise

Thanks to its passive, power-free design, the P DI One converts the impedance from high to low and balances the signal using a magnetic transformer that transfers audio while blocking unwanted DC voltage and RFI. This makes it especially effective at eliminating hum and buzz from ground loops while maintaining the tone of your instrument at every stage.

Great frother/stirrer especially for the price.
Color: Black, Size: Rechargeable
Best one available. Have used cheap ones from the store that work pretty good, but batteries are a pain. This is rechargeable and it has a push button that allows you to start it right away without having to turn it on to start it kind of like a power drill. If you start to press it it goes slow the harder you press the faster it goes. The different attachments are great. We use it for both coffee frothing as well as mixing up electrolyte drinks with water with the included mixing attachment. Crazy powerful and easy to use.

Strong motor. Works great
Color: Black, Size: Rechargeable
I really like this frother. The fact that it’s variable speed, rechargeable, and can spin at a high rate are all great features. I use it to blend collagen powder and cream into my coffee every morning. Also sometimes use it to Blend drinks. Strong motor. Like that the whisks are removable for cleaning and that it comes with different ones.

Works well, long use on single charge, high torque - be careful when starting
Color: Black, Size: Rechargeable
Not the most inexpensive powered whisker bur I've used other Typhor products and found them reliable for the task designed. I fell they don't cheap out on the rechargeable battery so I don't fell they will catch fire, as we are hearing about from other cheaper rechargeable items. I liked 2 things about this model the speed control is by a pressure single switch which I can control, not just pick speed 1,2,3. The swappable tips allow for different uses. I don't drink coffee but use the item to whisk eggs for an omelets and it has the torque to mix them without effort. In Fact need to only use half power else it will splatter out of my mixing vessel.

Still The Best Frother Ever!
Color: Black
I love how it is easy to use, how it holds a charge, and how much power it has. I've only charged it once since I got it & I've been using it on a daily basis!!! Though it isn't a long time, I'm happy with it so far! I definitely will recommend it to anyone looking for a great frother. If you are looking for one, look no further! You won't be disappointed! I've read some comments where they found it to be too strong that their drink spilled everywhere. But for me I have not had any incident of spilling over. I have used it both for my coffee and my matcha tea and it worked great without any spilling over. You just have to start with the lowest power and ensure that you have a large enough container to have a room for your frothing. My sister tried to use it recently during her visit to make us matcha tea. However, she experienced spillage all over the cup, because she had used a small cup. Otherwise, she liked it very much and said she will get one when her battery operated one stops working... Another thing I like about the product was the customer service that I had received. When I got my first order which came quickly, it wasn't working after having charged it over 24 hours. It was not turning on at all. I returned it and ordered a replacement which I received within a day or two. This time after charging it for the recommended amount of time, I was a bit skeptical when I turned it on. However, I was pleasantly surprised that it worked like it was supposed to and it has been working ever since having charged it only once so far. I may come back and give an update depending on how it does after 6 months of use, so keep in tune... I don't know if there is a way to write a new entry as a follow up to the old entry, so I'm going to add my follow up comment over here. May 23, 2025 - I love my frother more than I can say in words. It's functionality has not changed a bit from the time I have purchased it. It charge lasts several weeks to few months before I charge it again and the power is still the same. Recently I decided to buy another one for my office use. I like the white color and so tried it but that one wouldn't even turn on. And then I got a gray one to have a different color. That one was much weaker than the black one I own. Then I replaced it with another gray one within few days. I tried it and it was exactly the same as the one I already replaced. So then I decided to go with a black one again hoping that it would be the same as the one I have. The black one did much better than the gray ones in the strength or power of the frother. However, it is weaker than the one I already have been using since last August. While I am not very happy with the quality being inconsistent in all of the ones I have tried including the recent pictures of the black one, I have decided to keep the black one because it is relatively better than the gray ones I tried. What I don't understand is why there is inconsistency in the quality of the same product by the same maker. I am beginning to wonder if the black one I purchased in Augusta last year was anomaly of a quality and a good way. Maybe I lucked out on my older black frother, but I'm unsure if quality is going to get better if I were to order another one. I have a sister who is a pro in making coffee drinks and she was the reason I had ordered this frother to begin with. She uses a battery operated one at this time and I have been thinking about getting her one like mine. While I am still skeptical, I am going to give it a shot and order her one sometime soon. If it doesn't work, I guess we will return it back. But one thing that I am grateful is that I have been able to return every one of those that I have tried recently with no issues. I hope that I don't have to return my most recent purchase in black. I was not even able to review the new purchase because of the item being the same color which is crazy.

Outstanding Frother!
Color: Space Gray
Exceptional! This frother is in another league compared to the cheapo push button frothers. The motor is smooth, quiet and powerful. This has an intuitive thumb dial on top that operates smoothly with a wide range of smooth speed adjustment. It’s gentle enough to froth a little bit of milk for a macchiato and powerful enough to scramble 3 eggs. The head is removable for easy cleaning. It’s also rechargeable. I charged this the day I bought it on April first. I use it at least twice a day. It’s September 26th today and I have yet to recharge it and it’s not showing any signs of needing a charge. One minor quibble is that they give you 2 of the same frother heads. They are built so well, that I don’t imagine it ever wearing out. It would have been nice to get a whisk or something different. Not a deal breaker at all though.
