If you are choosing between the Pioneer DJ DDJ-400 and the DDJ-FLX4 in India, buy the DDJ-FLX4 unless the price gap decides it for you. The FLX4 is the current model: it works with four DJ apps instead of two, runs rekordbox on iOS and Android devices, adds Smart Fader and Smart CFX for first-time mixers, and runs on USB-C. The DDJ-400 is the older rekordbox controller it replaced, and it still does the core job well.
On proaudiobrands.com in September 2026, the DDJ-400 is listed at ₹27,990 and the DDJ-FLX4 at ₹37,900. That is a difference of ₹9,910 for a single controller in each case.
Pick the DDJ-400 if you mix on a laptop with rekordbox, want the lowest entry price into the Pioneer DJ layout, and do not need a phone, Serato or Traktor. Pick the DDJ-FLX4 if you want software choice, mobile DJing, microphone audio in your live stream, or a controller that is still in AlphaTheta's current range.

Is the DDJ-400 discontinued?
Yes. On pioneerdj.com, AlphaTheta (the company behind Pioneer DJ) lists the DDJ-400 as an archived product in every region, while the DDJ-FLX4 is listed as active. The DDJ-400 was announced in June 2018; the FLX4 followed in November 2022 and took its place as the entry 2-channel controller.
Archived does not mean unsupported overnight. The DDJ-400 still has its product page, manuals and firmware tools on the Pioneer DJ site, and rekordbox continues to recognise it. What it does mean is that new features are aimed at the FLX4, and over the years software support for an older controller can narrow. If you plan to keep a controller for four or five years, that matters more than any single spec.
What stays the same
A lot. Both controllers share the same basic footprint: 482 mm wide, about 272 mm deep, and 2.1 kg. Both fit in a backpack with a laptop. Both are 2-channel controllers with jog wheels, tempo sliders, a 3-band EQ and trim on each channel, a crossfader, Beat FX, eight Performance Pads per deck, and a built-in sound card.
The audio section is also closely matched on paper. Pioneer DJ's manuals list the same 103 dB S/N ratio over USB, 0.005 % total harmonic distortion, and a master output of 2.1 Vrms into 10 kΩ for both units. In practice, a speaker system will not sound different between the two. Your speakers, cables and room decide the sound far more than the controller.
Connections are the same types too: one pair of RCA master outputs for powered speakers or an amplifier, a 3.5 mm stereo mini jack for headphones, and a 1/4 inch microphone input. Neither controller has a booth output or XLR master outputs, so for a proper PA you will usually run RCA into a mixer or use an RCA to 1/4 inch or RCA to XLR cable into powered speakers.
Both are bus powered from a computer. Pioneer DJ rates the FLX4 at DC 5 V, 500 mA on bus power and the DDJ-400 at DC 5 V, 500 mA, so a single USB cable to your laptop is enough in normal use.
Where the DDJ-FLX4 is different
Software choice
The DDJ-400 was built for rekordbox. Pioneer DJ later added support for Algoriddim's djay (djay for iOS and djay Pro for PC/Mac). That is the full list on its product page.
The FLX4 unlocks rekordbox, djay, Serato DJ Lite and Traktor Play for free when connected, and you can buy a Serato DJ Pro licence or subscription later. Note that djay Pro itself is a paid app. For a beginner this matters because DJ friends, YouTube teachers and DJ schools in India do not all use the same software. With the FLX4 you can follow the course you like without changing hardware.
Phones, tablets and Bluetooth
The FLX4 works with a PC, Mac, iPhone, iPad, or an Android phone or tablet. With rekordbox for iOS or Android you can connect by USB-C cable or by Bluetooth. Pioneer DJ's manual is clear that Bluetooth carries control data only: sound does not come out of the controller over Bluetooth, so in that mode you cable the phone's audio to your speakers separately. When using a phone, the FLX4 needs its own power from a USB power adapter or a 9 V mobile battery (the manual rates it at DC 9 V, 3 A on an adapter). Pioneer DJ also notes that with rekordbox for iOS on an iPhone or iPad connected by the included USB-C cable, sound can play from the iPhone or iPad itself, so you can start without external speakers. That option is not available on Android.
That is why the FLX4 has two USB-C ports: one for the device, one for power when there is no laptop to supply it.
Smart Fader and Smart CFX
Smart Fader automatically adjusts volume, bass level and BPM as you move the channel faders or crossfader, so two tracks blend smoothly even across genres. Smart CFX applies preset combinations of effects from one knob turn. Purists will switch Smart Fader off once they learn to beatmatch and EQ by hand, and that is the right approach. For a first house party, though, it lowers the chance of a train-wreck transition.
The DDJ-400's answer to learning is the Tutorial feature in rekordbox, which walks you through the controls on screen. Its mixer uses a FILTER knob per channel, where the FLX4 uses CFX knobs that default to the filter but can be assigned other effects in the software.
Microphone audio for live streams
On the FLX4, the microphone signal is mixed into the USB audio output. So if you stream a set from one laptop, viewers hear your mix and your voice without an extra interface, as long as no Bluetooth device is connected. On the DDJ-400, Pioneer DJ's manual states the mic sound cannot be recorded in rekordbox and cannot be sent to the computer's speakers, so streaming your voice needs a separate interface or route.
Pad modes
Both give you eight pads per deck. The DDJ-400 buttons select Hot Cue, Beat Loop, Beat Jump and Sampler, with Keyboard, Pad FX 1, Pad FX 2 and Key Shift on Shift. The FLX4 buttons select Hot Cue, Pad FX 1, Beat Jump and Sampler, with further modes on Shift. Pioneer DJ describes the FLX4 pads as back-lit rubber pads. Both cover what a beginner needs in the first year.
Class compliant, 48 kHz and security
The FLX4 is class compliant on PC and Mac, so no audio driver install is needed. It supports 44.1 kHz and 48 kHz sampling, which helps if you also stream or record video at 48 kHz. Both controllers have a Kensington security slot, a small but useful point for DJ academies and shared college society gear.
Which controller suits which DJ
Bedroom DJ learning on a laptop
Either works. If your budget is fixed at under ₹30,000 and you are happy with rekordbox, the DDJ-400 gets you the Pioneer DJ club layout for less. If you can stretch, the FLX4 gives you more room to change software later.
Mobile and phone-first DJs
The FLX4, clearly. The DDJ-400's product page lists djay for iOS, but not Android devices or rekordbox for mobile.
Streamers and content creators
The FLX4, because the mic goes out over USB with the music.
Future club DJs
Both share the layout logic of Pioneer DJ club gear, so the habits carry across. The real long-term goal is learning rekordbox library prep, cue points and beatgrids, which works on both. When you outgrow a 2-channel beginner controller, the step-ups on our site include the 4-channel DDJ-FLX6-GT, the DDJ-FLX10 4-channel performance controller, and for scratch DJs on Serato DJ Pro the DDJ-REV7. If you want a system that runs without a laptop, the XDJ-RX3 all-in-one is the booth-style option. You can compare the rest in our controllers collection.
Buying a DJ controller in India: practical points
Power and voltage
On bus power, the controller draws from your laptop, so the laptop charger is what meets the mains. Voltage fluctuation and power cuts are common in many Indian cities, so run the laptop and powered speakers from a UPS or a stabilised supply at gigs. Pioneer DJ warns that the FLX4 cannot run on bus power when the computer's USB port supplies too little power or when the computer has other devices connected. Use a direct port on the laptop, not a cheap hub.
Headphones
Pioneer DJ's FLX4 manual states that bus power will not work with headphones under 32 Ω or with a mono plug in the headphone jack. Most DJ and studio headphones meet that, but check before buying a very low impedance pair. A closed-back studio pair such as the Beyerdynamic DT 770 PRO 32 ohm blocks outside noise, which helps when cueing at a loud party. More options are in our headphones collection.
Speakers for home practice
Both controllers output on RCA, so any powered speaker with RCA or a matching cable will work. In a typical Indian bedroom, small powered monitors such as the Yamaha HS3 pair are enough for practice and keep neighbours on your side. For a bigger living room or small events, see our guides linked below.
Heat, dust and storage
Pioneer DJ specifies a tolerable operating temperature of +5 °C to +35 °C and 5 % to 85 % humidity with no condensation for both controllers. A summer terrace gig or a hot car boot can exceed that. Keep the controller in a padded bag or cover when not in use, because dust in faders and jog wheels is the usual cause of scratchy controls.
Warranty and service
Buy from an authorised dealer so the warranty is honoured in India and genuine service is available. Grey-import controllers can look identical but may not be covered locally.
Which one should you buy?
- Tightest budget, laptop plus rekordbox: the DDJ-400 at ₹27,990. It has the same core controls and audio figures as the FLX4 on paper.
- First controller you plan to keep for years: the DDJ-FLX4 at ₹37,900, because it is the current model with wider software support.
- DJing from an iPhone, iPad or Android device: the DDJ-FLX4.
- Live streaming with a microphone: the DDJ-FLX4.
- Want to learn on Serato or Traktor: the DDJ-FLX4.
- Already outgrowing two channels: skip both and look at the DDJ-FLX6-GT or DDJ-FLX10.
FAQ
What is the DDJ-400 price in India?
The Pioneer DDJ-400 is listed at ₹27,990 on proaudiobrands.com in September 2026. Prices can change with stock and exchange rates, so check the product page for the current figure.
What is the DDJ-FLX4 price in India?
The Pioneer DDJ-FLX4 is listed at ₹37,900 on proaudiobrands.com in September 2026. That is ₹9,910 more than the DDJ-400.
Is the DDJ-FLX4 better than the DDJ-400?
For most new buyers, yes. It adds Serato DJ Lite and Traktor Play support, phone and tablet use, Smart Fader, Smart CFX and mic audio over USB. The audio specifications Pioneer DJ publishes are the same for both, so it is not an upgrade in sound quality.
Does the DDJ-400 work with Serato?
Pioneer DJ's DDJ-400 page lists rekordbox and djay compatibility. If Serato DJ Lite or Serato DJ Pro is your plan, choose the DDJ-FLX4, which lists Serato support.
Do I need to buy rekordbox for the DDJ-400 or FLX4?
No. Pioneer DJ states that rekordbox performance features unlock when the controller is connected to your PC or Mac. Extra features such as Cloud Library Sync need a paid rekordbox plan.
Can I connect the DDJ-FLX4 directly to speakers?
Yes. It has a built-in sound card with RCA master outputs, so it connects to powered speakers or an amplifier with a single RCA cable. The DDJ-400 works the same way.
Which is the best DJ controller for beginners in India?
For most beginners the DDJ-FLX4 is the safer pick because it is current and supports four DJ apps. If budget is the deciding factor and you will use rekordbox on a laptop, the DDJ-400 still covers everything needed to learn mixing.
