It features level control, multiple input options including 1/8" TRS, 1/4", and RCA, and a mono merge function, making it an essential tool for musicians and sound engineers seeking versatility and superior sound quality. ## Description A passive DI intended for use with your laptop and other devices, the Radial Trim-Two is one of the most flexible direct boxes we've seen at Sweetwater. From its convenient 1/4", RCA, and mini-TRS inputs to its ready-access volume control, the Trim-Two is a must-have for AV presenters, DJs, and keyboard players. The inputs are wired in parallel, letting you split the signal to feed your monitors or another destination. Under the hood, a pair of beefy Eclipse transformers isolate and balance the signal, delivering linear frequency response and handling up to +15dB, giving your -10dB consumer-level devices plentiful headroom. Radial Trim-Two Stereo DI at a Glance: Convenient and easy to use Built Radial tough Convenient and easy to use The Radial Trim-Two rocks a front-panel stereo level control, which makes it easy to adjust your volume in any setup. The stereo-to-mono switch is equally handy, letting you effortlessly collapse Review: The Trim Two Passive - a fantastic solution for converting unbalanced to balanced audio signals - Prior to purchasing the Trim Two Passive, I had used (more like "tried") two other passive Direct Injection boxes (DI Box) from different brands. The reason I started using a DI box is due to the fact that I have the Presonus Eris E5 Mk II desktop active speaker system. This particular speaker brand provides inputs on the rear for balanced XLR and TRS cables, along with unbalanced RCA cables. The problem is that although the speakers are absolutely superb sounding, their RCA inputs tend to be very, very sensitive to RFI noise (i.e. hum, buzzing, hiss, etc) and I was experiencing a persistent, annoying buzz. After doing quite a bit of research, I've come to realize that you can convert unbalanced signals to balanced versions with the use of a Direct Injection Box, or more common referred to as "DI Boxes." As I mentioned, I tried two previous DI boxes - all solidly constructed from other brands, but they were inexpensive, ranging from $29.95 to $49.95. And although they got rid of the RFI issues I had been experiencing, they had some slight, yet noticeable audio quality issues such as a slight roll off of high frequencies, and with the last DI box I tried, the bass wound up being overly bloated. In addition, my gain/volume levels dropped a good 10 - 15 DB which was quite noticeable, causing me to have to turn up the gain on all of my input components such as DAC's to their maximum level to offset this gain issue. Then I heard about and read articles about Radial Engineering and their highly rated line of DI Boxes, saw the reviews, and decided to try this Trim Passive Two DI Box for a number of reasons, but specifically for the gain volume control they have on this box. So when the box arrived, I was extremely impressed with the superb (built like a tank) build quality, the inputs, and the quality of the materials used. It took all but a minute to install and I began listening to music - mostly classical and jazz. And there was "no" gain loss at all. All I can say is "wow," because the audio quality was there - nothing added, nothing subtracted. All the dynamics of large orchestras such as experienced with classical music, were there. Bass was solid - and I mean tight (not bloated as with previous DI boxes), and the mids and highs were natural without any perception of any roll-off characteristics. It was readily obvious that you get what you pay for here. This is perhaps the best $150 that I've expended on an audio-related device in a long time. The Radial Engineering Trim Two Passive not only got rid of all of the RFI noise I was experiencing with the Presonus speakers (which, by the way, are known for that issue), but when now using the balanced XLR connectors to the speakers - the sound quality just began to sing!!!! So DI boxes convert unbalanced audio signals that are typically related to RCA audio cables, and then convert them to quiet (noise-free) balanced audio output. In the case of the Trim Two Passive, the output side uses XLR cables which the Presonus speakers have also. I just couldn't be happier with my purchase and I highly recommend any of these Radial Engineering products. Remember, it's easy to at first spend $30 to $50 or so on a cheaper DI box, but in most cases, you will lose quite a bit of gain plus some audio deterioration. Pay a few dollars more - stick with products like you see from Radial Engineering and you will be quite satisfied. Have a great Life.... Review: Awesome! Connects iPod to mic cable - This device works great to let me play music from my iPod through the sound system at church. The volume control on the device is convenient, and there are multiple connectors for flexibility. I connect the iPod with a 3.5mm cable and plug a microphone cable into the device. ## Features - Stereo Passive DI with Level Control - 1/8" TRS Input Connectors - Mono Merge - 1/4" - RCA ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #37,254 in Musical Instruments ( See Top 100 in Musical Instruments ) #2,499 in Stage & Studio Cables | | Customer Reviews | 4.7 out of 5 stars 35 Reviews | ## Images ![Radial Trim-Two 2-Channel Passive a V Direct Box - Image 1](https://m.media-amazon.com/images/I/71v8dU6hcoL.jpg) ![Radial Trim-Two 2-Channel Passive a V Direct Box - Image 2](https://m.media-amazon.com/images/I/71weJV3TVoL.jpg) ![Radial Trim-Two 2-Channel Passive a V Direct Box - Image 3](https://m.media-amazon.com/images/I/719o-Tc6zvL.jpg) ![Radial Trim-Two 2-Channel Passive a V Direct Box - Image 4](https://m.media-amazon.com/images/I/71dU8zoeirL.jpg) ![Radial Trim-Two 2-Channel Passive a V Direct Box - Image 5](https://m.media-amazon.com/images/I/71v2URXnZbL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Trim Two Passive - a fantastic solution for converting unbalanced to balanced audio signals *by B***N on December 17, 2020* Prior to purchasing the Trim Two Passive, I had used (more like "tried") two other passive Direct Injection boxes (DI Box) from different brands.

Connects iPod to mic cable *by G***N on December 16, 2025* This device works great to let me play music from my iPod through the sound system at church. The volume control on the device is convenient, and there are multiple connectors for flexibility. I connect the iPod with a 3.5mm cable and plug a microphone cable into the device. ### ⭐⭐⭐⭐⭐ Excellent for running tracks *by A***L on January 30, 2025* This is perfect for a simple set up for running tracks from an iPad. I have tried every set up imaginable in the 12 years I’ve run tracks in my bands and this is the BEST solution hands down. I can sent the click and track to FOH via XLR and it to my small mixer via 1/4” at the same time, ensuring I’m in total control of my track mix. It also allows me to turn down the volume affecting only the FOH while still leaving it on for me if I need to kill tracks out front or if I want to test tracks without blaring them thru the PA. And Radial products are absolute work horses. They can handle the toughest of road warrior conditions.
