The Denon DJ Prime 4+ is, for us, the best standalone DJ system: four full decks, a 10.1 in touchscreen, balanced XLR outputs and no laptop required. It is a serious investment rather than a learner's buy. Here is what it does well, and where its limits lie.
The Prime 4+ is a different kind of machine from the laptop controllers above it. It is a standalone system, which means it has its own computer, its own screen and its own software, Denon's Engine OS, so it plays your music straight from a USB stick or SD card with no laptop in the chain at all. That laptop-free reliability is exactly what working and mobile DJs need, and the Prime 4+ pairs it with four full decks, a large 10.1 in touchscreen and the professional connections a real venue demands. At around £1,499 it is a professional investment, not a first deck, but for what it is, nothing else here comes close, which is why it is our best standalone pick.

The verdict from Andre Silva, DJ gear reviewer
The best standalone system, for the serious or working DJ. The Denon DJ Prime 4+ is a different kind of machine: a four-deck standalone unit that needs no laptop, reading your music straight from a USB stick or SD card through Engine OS on a large 10.1 in touchscreen. It has the connections a real venue needs, including balanced XLR master and booth outputs, a separate zone output, and microphone and line inputs. At around £1,499 it is a professional investment rather than a learner’s buy, but for mobile and club work where reliability without a laptop matters, nothing else here comes close.
The big motorised-feel jogs and bright screen make it feel like a club booth condensed onto one slab.

The Prime 4+ is the right system for the working, mobile or aspiring professional DJ who needs to play without a laptop and wants room to grow into four decks. Its defining feature is standalone operation: there is no laptop to crash, run out of battery or freeze mid-set, because the unit reads your music directly from a USB stick or SD card through Engine OS on its large touchscreen. The professional connections, balanced XLR master and booth outputs, a separate zone output for a second room, and microphone and line inputs, are exactly what a venue or a mobile rig needs. For someone who is gigging or about to, it is a machine you will not outgrow.
It is decidedly not for beginners. At around £1,499 it costs five to fifteen times as much as the laptop controllers here, and a learner does not need four decks, a zone output or balanced XLRs while they are still mastering the basics. Anyone starting out is far better served by our best overall pick, the Pioneer DDJ-FLX4, or the budget Hercules Inpulse 200 MK2. Buy the Prime 4+ when you are ready to invest, not to learn.
Running without a laptop is the Prime 4+'s reason to exist, and it does it superbly. You load a USB stick or SD card, and Engine OS reads your library, waveforms, cue points and playlists directly, with no computer involved. The large 10.1 in multi-touch screen is bright and responsive, showing four waveforms at once, and you browse, search and set cues right on it. Built-in Wi-Fi adds streaming services, so you are not limited to what is on your drive. For reliability at a gig, where a laptop crash can end your set, this laptop-free design is genuinely reassuring.
The Prime 4+ gives you four full decks, each with a large 152 mm jog wheel carrying an on-jog display that shows the artwork and the position, so you can mix, layer and route four sources at once. There are thirty-two performance pads in total, eight per deck, for hot cues, loops, the sampler and slicer. The jogs are substantial and feel close to club players, and the whole control surface is laid out like a professional booth condensed onto one slab. It is a lot of capability, and it rewards a DJ who has the skills to use it.
This is where the Prime 4+ leaves the laptop controllers far behind. It has balanced XLR master and booth outputs for clean, professional connection to a venue's PA, a separate zone output to feed a second room independently, and two microphone inputs and two line/phono inputs for external players or turntables. It is mains powered rather than bus-powered, as a unit this capable needs to be, and at 6.6 kg it is built like professional gear. That weight is the trade-off for the connectivity and the screen, and it is the clearest sign that this is a tool for gigging, not for the bedroom.
There are two, and both come from what the Prime 4+ is. First, the price: at around £1,499 it is far beyond what a beginner should spend, and the money only makes sense once you genuinely need standalone operation and four decks. Second, at 6.6 kg and with a large footprint it is heavy and bulky, overkill for a bedroom and a real consideration for transport. Neither is a fault, but together they mean the Prime 4+ is strictly a serious or working DJ's purchase, not a starting point.
Best for: the working, mobile or aspiring professional DJ who needs laptop-free reliability, four decks and balanced outputs. Not the pick for a beginner or a bedroom setup, where a laptop controller like the Pioneer DDJ-FLX4 makes far more sense.

No, and that is the point of it. The Prime 4+ is a standalone system that runs Denon's Engine OS on a built-in 10.1 in touchscreen and plays your music straight from a USB stick or SD card, with no laptop required. It also has built-in Wi-Fi for streaming services. This laptop-free reliability is why working and mobile DJs choose standalone gear.
For most beginners, no. At around £1,499 the Prime 4+ is a professional investment, and a learner is better served by a £99 to £280 laptop-based controller while they build their skills. The Prime 4+ makes sense once you are gigging, need four full decks and laptop-free reliability, or simply want to invest in gear you will not outgrow.
It has the connections a real venue needs: balanced XLR master and booth outputs, a separate zone output for a second room, two microphone inputs and two line/phono inputs for external players or turntables. That professional connectivity, plus four standalone decks and the large screen, is what separates it from the laptop controllers on our list.
The Denon DJ Prime 4+ is our best standalone DJ system because it delivers the thing working DJs most need, laptop-free reliability, alongside four full decks, a large touchscreen and the balanced outputs a real venue demands. It is held back only by its price and weight, neither of which is a fault so much as the cost of being a professional tool. For a gigging or mobile DJ it is in a class of its own here. If you are starting out, though, do not buy it: our best overall pick is the Pioneer DDJ-FLX4 and the budget choice is the Hercules Inpulse 200 MK2.
