Should I get Pyle-Pro PDC21 for $8 or is this significantly better?** A: A normal DI box is $50 so I wouldn't go too much lower than this. These seem to work well. I've only had one go bad in the past year or so and I purchased like 8 for my church. **Q: Can this reduce a speaker level signal to a line level signal? E.g. if I wanted to take a speaker level and connect it to a mixer.** A: YES. The other answers are not accurate. This device as well as many other DI Boxes can make a Line Level 'copy' of the high power signal going to a speaker. This is a common use however this yes comes with a major caveat. The source (1/4 " INPUT) can be a highly amplified signal, such as the speaker output of a 100W guitar amplifier. The output signal (XLR OUTPUT) will be what the mixer wants (Line Level). CAVEAT: There must be a load connected to the THRU (Parallel OUT on this device). This load can be a speaker or speaker load simulator, basically what you would normally connect to the amp. Without a load connected, no signal flows and nothing will be output. Worse yet, without a load connected, many amps will fry. Amp to DI box to Speaker(1/4" OUT) and Mixer (XLR OUTPUT) is commonly used by guitarists. This allows the PA Mixer or Recording Audio Interface to get all the good sound that the guitar signal chain has built, only missing coloring from the speaker cabinet. If needing your speakers to be silent while still getting a good output on the XLR, adding a decent amp Attenuator or Load Simulator after the DI Box can reduce the power reaching the speaker to or near zero. Note: Many higher end Attenuators and Load Simulators have a built in DI Box. **Q: can i use this to hook up my 6505+ to my m-box?** A: If you have the combo version, it has an XLR out already, so no DI required. The head version doesn't seem to have this option, so you could use the preamp out, but I'm not sure if you could hear a difference between using a DI or running the 1/4" into the line level input of the M-Box. You'll lose the tone you get from the power amp tubes either way. The main point of a DI is to convert a 1/4" instrument signal to a balanced XLR signal if you're going into a stage snake. Effectively running a 50' or 100' 1/4" cable will generally introduce noise and reduce signal quality, so the DI is a great option. I've used this passive DI box in live situations for the past year, and it's worked like a champ. I run my tracks (from an iPod) through it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solucionó mi problema de ruido *by H***Z on 23 January 2026* Excelente calidad, solucionó el problema de ruido (con el switch ground-lift) que tenía al usar un bajo eléctrico ### ⭐⭐⭐⭐⭐ Produto muito bom *by M***O on 8 April 2025* Produto entregue em perfeitas condições, conforme previsto ### ⭐⭐⭐⭐⭐ Qualité et fonctionnement *by G***É on 8 February 2025* Fonctionne tel que prévu, peu de perte aucun bruits. ## Frequently Bought Together - Behringer Ultra-DI DI400P High-Performance Passive DI-Box - GearIT XLR Microphone Cable (10 Feet, 10-Pack) - XLR Male to Female, Balanced Shielded Cable for Mic Mixer, Recording Studio, Podcast - Black, 10ft, 10 Pack - GEARit Guitar Instrument Cable (15ft 2-Pack) 1/4 Inch to 1/4 inch TS Straight Male to Male 6.35mm Mono Jack with Alloy Connector and Nylon Braid --- ## 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.gr/products/288942052-ultra-di-di400p-professional-high-performance-passive-di-box-black](https://www.desertcart.gr/products/288942052-ultra-di-di400p-professional-high-performance-passive-di-box-black) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-16*
