I do allot of A/V work and own a few of these. I also own other similar items from other manufacturers. This adapter is perfect for tying in any PC computer, iPod, iPad or similar devise to a pro audio sound system and works like a charm at doing so. Rapco Horizon is a good company that makes quality products here in the USA. I also have the other model from Rapco listed below with the ground lift switch. It's kind of a nice feature to have. But with my experience, I usually find myself flipping that ground lift switch to get rid of the noisy interference. So instead, I'm an electrician and electronics guru. I just saved myself the money and have been buying this Rapco model without the ground lift switch and have been opening up the item and disconnecting the ground wire from pin 1 of the XLR connector where the ground lift switch would be in place of and permanently leaving the ground in the lifted position. I also bypassed and removed the potentiometer "volume control knob" on my PC DI's because it would usually add confusion to the presenter when they are having a sound problem and are trying to trouble shoot without a sound tech present. I like to set the audio level of the laptop computer output to 75%, then adjust the mixes input gain and volume. That typically works pretty well and leaves the presenter some wiggle room for volume adjustments on the PC. Other great products to use of similar type. Rapco Horizon LTIGLBLOX Laptop Interface With Ground lift Rapco Horizon- LTIGLBLOX "With Ground Lift Switch" This is the second most cost effective solution out of the four different types listed on here. What I like about the model listed is they have the 1/8" stereo wire permanently attached and won't walk off or become detached accidentally during use. A great value and built well. Switchcraft 318 Mini AudioStix Switchcraft - 318 AUDIOSTIX Another great choice. Doesn't have the 1/8" Stereo wire permanently attached like the Rapco products listed above. But a Black 4 foot 1/8" stereo to 1/8" stereo cable is included. This is the more expensive adapter of the four products I have listed here. Whirlwind Isopod Whirlwind - Isopod I like this model for certain uses because it doesn't have the volume control on the adapter. When people are doing presentations and aren't getting audio for one reason or another, a volume control can confuse them and they end up turning it down creating a chain reaction of events of audio issues. But on a negative side. The 1/8" Stereo cord can become unplugged. I do like that option sometimes depending on how I'm using it and placing it in the system. For Example. If run a combo VGA / 1/8" Audio cord from Laptop to the Projector. At the end of the VGA cable plugging into the projector. I'll hook up the other end of that 1/8" Audio connection to the Isopod and convert to the XLR run to the Audio Mixer. Please remember, all of these DI adapters only support Mono operation and not stereo. Meaning it's taking a Stereo connection from the Laptop or Tablet and converting it to a Mono connection. If you need stereo operation, then you will need to go with some other PCDI interconnects. Try looking up Whirlwind PCDI for starts.

Do not believe the myths that it is safe to simply plug a 1/8" to 1/4" adapter into your system. The wiring on your mini plug is completely different than a balanced 1/4" TRS or unbalanced 1/4" mono plug. This device is awesome and allows on the fly, immediate, volume control without having to go straight to your mixer controls. We use this for our laptop integration into our sound system at church, and it works great. Highly suggested. ## Frequently Bought Together - Rapco Horizon LTIBLOX Laptop Interface Device - Amazon Basics XLR Male to Female Microphone Cable for Speaker or PA System, All Copper Conductors, 6MM PVC Jacket, 6 Foot, Black - Rapco Horizon LTIGLBLOX Laptop Interface With Ground lift --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/3502899-horizon-ltiblox-laptop-interface-device](https://www.desertcart.de/products/3502899-horizon-ltiblox-laptop-interface-device) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-08-11*
