Try it before you buy
We have the DDJ-FLX4 as a simulator in your browser: every control works and is explained with its page in the manual — no device, no sign-up. It is also the example device in the DJLearn learning path. The simulator needs a large screen: a desktop, a laptop or a tablet turned sideways.
Price range within the category
DJ controllers at DJLearn range from up to €100 to over €600. This product sits at €200 to €350. That is the middle of the category.

What the controls are called on this device
The example device in the learning path is the DDJ-FLX4. This table translates every control from the course to this device — with the page of the manufacturer’s manual where it appears. If a control is missing, the manual does not list it.Terms as printed in the manual — we evaluated the German edition, so the manual’s own wording is German.
| In the course | On the device | Manual p. |
|---|---|---|
| EQ high | EQ (HI)-Regler | 27 |
| EQ mid | EQ (MID)-Regler | 27 |
| EQ low | EQ (LOW)-Regler | 27 |
| Filter / colour | CFX-Regler One knob per channel for Sound Color FX — or for Smart CFX when the SMART CFX button is lit (pp. 27–28). Centre position = original sound. It works as a filter when a filter is selected in the software. | 27 |
| Tempo fader | TEMPO-Schieberegler | 18 |
| Jog wheel | Jog-Rad | 20 |
| Channel fader | Kanalfader | 29 |
| Crossfader | Crossfader | 29 |
| Headphone cue | Kopfhörer-CUE-Tasten (Kanal) | 28 |
| Headphone mix | HEADPHONES MIX-Regler | 28 |
| Master level | MASTER LEVEL-Regler | 26 |
| Performance pads | Performance Pads | 19 |
Where the filter would be, there is a CFX knob per channel, as on the FLX2 (p. 27); the SMART CFX button next to it (p. 28) switches what it controls. ⚠️ The manual only ever refers to deck 1 and deck 2.
What you still need
The device alone does not make an evening. What follows here comes from the connectors of your setup — for the devices whose manual is in our archive, with a page number.
For the build
RCA cable (2× phono)
The master output is an RCA socket. For active speakers with RCA inputs you need an RCA-to-RCA cable; if your speakers use jack or XLR, the other end has to match.
Check first
Jack adapter 6.3 to 3.5 mm
The headphone socket is the small 3.5 mm one. Many DJ headphones come with a 6.3 mm plug — usually an adapter is included or screwed on. Check before you want to play, not after.
USB power supply or power bank
On a phone or tablet the device does not draw its power from the source. The manual names a USB power supply or a mobile battery for this — neither is included.
Deliberately without prices: a cable price is the most short-lived figure a page can carry. This says WHAT is missing, not what it costs.
