DJ Cable Connection Guide NZ: Which Cable Do I Need?
Quick answer: to connect DJ gear, match the output on your controller or mixer to the input on your speakers. The most common NZ setup — a DJ controller with RCA outputs into powered speakers with XLR inputs — needs a dual RCA to dual XLR male cable. If your controller has XLR outputs, use two XLR male-to-female leads. Use the table below to find the exact cable for your setup.
Which cable do I need? (output → input)
| Your output (controller / mixer / source) | Your input (speaker / amp / mixer) | Cable you need |
|---|---|---|
| XLR (master out) | XLR | XLR male to female × 2 (left + right) |
| RCA (red/white) | XLR | Dual RCA to dual XLR male |
| 6.35mm (1/4") TRS jack (booth / master out) | XLR | TRS to XLR male × 2 |
| RCA | 6.35mm (1/4") jack | Dual RCA to dual 6.35mm TS |
| RCA | RCA | RCA to RCA stereo pair |
| 3.5mm headphone / aux (phone, laptop) | RCA | 3.5mm to dual RCA |
| 3.5mm headphone / aux (phone, laptop) | XLR | 3.5mm to dual XLR male |
| 3.5mm headphone / aux (phone, laptop) | 6.35mm (1/4") jack | 3.5mm to dual 6.35mm |
| 6.35mm (1/4") TRS stereo out | Two 1/4" mono inputs (left + right) | TRS to dual TS insert / Y cable |
| One XLR output | Two XLR inputs | XLR Y splitter (1 female to 2 male) |
| Laptop USB-C or USB-A port | DJ controller / MIDI (USB-B) | USB-C or USB-A to USB-B cable |
| Microphone (XLR) | Mixer mic input (XLR) | XLR male to female |

Know your connectors
XLR (3-pin)
The round, locking pro-audio connector. XLR carries a balanced signal, which cancels out hum and interference, so it's the best choice for longer runs from the DJ booth to PA speakers. Cables are male at one end (pins) and female at the other (holes): signal flows from the female end (source) into the male end (destination). Most powered PA speakers and higher-end controllers have XLR connections.
RCA (phono)
Red (right) and white (left) plugs, used on most entry-level DJ controllers, turntables, CDJs, home amps and hi-fi. RCA is unbalanced, so keep runs short (ideally under 3–5m) and use a well-shielded cable to avoid hum.
6.35mm (1/4") jack — TRS vs TS
Two versions look almost identical. TRS (tip-ring-sleeve, two black rings) carries a balanced mono signal or stereo headphones. TS (tip-sleeve, one ring) is unbalanced mono, like a guitar lead. DJ booth outputs and audio interface outputs are usually balanced TRS; use a TRS-to-XLR cable to keep them balanced into a speaker.
3.5mm (1/8") aux
The small headphone jack on phones, laptops and tablets. Handy for a guest playing from a phone or for background music, but it's a consumer-level signal — use it for backup, not your main output.
USB-B
The square USB plug on most DJ controllers, MIDI keyboards and audio interfaces. It carries control data and audio between the controller and your laptop — the other end is USB-C or USB-A depending on your laptop.
Balanced vs unbalanced: why it matters
A balanced cable (XLR, or TRS into XLR) carries the signal twice, one copy flipped. At the speaker the copies are combined and any noise picked up along the way cancels out. That's why balanced connections stay quiet over 10m or more. Unbalanced cables (RCA, TS, 3.5mm) have no noise cancellation, so they're fine for short runs but can hum or buzz over long distances or near power cables and lighting.
Rule of thumb: if your gear has a balanced output (XLR or TRS), use it. If it only has RCA, keep the cable as short as practical.
Common DJ setups and what to buy
1. DJ controller to two powered speakers
Entry-level controllers (most Pioneer DDJ, Numark, Hercules and similar) have an RCA master out. Powered PA speakers usually take XLR or combo XLR/1/4" inputs. You need one dual RCA to dual XLR male cable — 1.5m if the speakers sit beside the table, 3m if they're on stands. If your controller has XLR master outs, use two XLR leads instead.
2. DJ mixer to a PA system or venue desk
Use the mixer's XLR master outs with two XLR male-to-female leads. For long runs to a front-of-house desk, 5m XLR leads keep the signal clean.
3. Booth monitors
Most mixers send the booth output on 1/4" TRS jacks. Run two TRS to XLR male cables into powered monitors with XLR inputs. If the booth out is RCA and the monitors take 1/4" jacks, use a dual RCA to dual 6.35mm TS cable.
4. Turntables or CDJs into a mixer
Use a shielded RCA to RCA stereo pair from each deck into the mixer's phono (turntables) or line (CDJs) channels. Turntables also need their thin ground wire connected to the mixer's ground screw, otherwise you'll hear a hum.
5. Phone or laptop as a backup source
A 3.5mm to dual RCA cable plugs a phone or laptop into a mixer's aux/line input — the cable every DJ should keep in the bag for emergencies.
6. Phone or laptop straight into a PA
No mixer? A 3.5mm to dual XLR male cable runs a phone or laptop headphone output directly into powered speakers or a PA desk with XLR inputs — ideal for speeches, background music and small events. For a mixer or monitors with 1/4" line inputs, use a 3.5mm to dual 6.35mm cable.
7. Connecting the controller to your laptop
Most DJ controllers (Pioneer DDJ, Numark, Hercules, Traktor and others) connect with a square USB-B port. Newer laptops only have USB-C, so a USB-C to USB-B cable avoids a dongle — a loose adaptor is a common cause of dropouts mid-set. Older laptops use the USB-A to USB-B version. Keep the cable to 2m or shorter for a reliable connection.
8. Splitting one output to two speakers
An XLR Y splitter sends one XLR output to two speakers or inputs — handy for a mono PA, a sub plus top, or feeding a recorder. A TRS to dual TS insert cable splits a stereo 1/4" output into separate left and right jacks, or connects a mixer channel insert to outboard effects.
What length do I need?
- 1.5m: controller to speakers on the same table, decks to mixer.
- 2–3m: controller to speakers on stands either side of the DJ table.
- 5m+: DJ booth to PA speakers or a venue desk — use balanced XLR.
Buy for the real run plus a little slack, but don't coil up excess — long unbalanced runs pick up more noise.
Fixing hum, buzz and no sound
- Hum from turntables: connect the ground wire to the mixer's GND terminal.
- Buzz with laptop on charge: a ground loop — try unplugging the laptop charger, or plug all gear into the same power board.
- Thin or quiet sound from a 1/4" output: you may be using a TS cable on a TRS output (or the other way around) — match TRS to balanced outputs.
- Distorted sound: don't plug a speaker-level or headphone output into a mic input; use line inputs and keep gain at sensible levels.
- Only one side working: check both left and right plugs are fully seated and the master output is set to stereo.
- Controller dropping out: plug the USB cable straight into the laptop (no hub or dongle) and use a cable 2m or shorter.
Frequently asked questions
What cable do I need to connect a DJ controller to powered speakers?
Check the controller's master output. If it's RCA (red/white), use a dual RCA to dual XLR male cable for speakers with XLR inputs, or dual RCA to dual 6.35mm for speakers with 1/4" inputs. If it's XLR, use two XLR male-to-female cables.
Is XLR better than RCA for DJing?
Yes, for anything beyond a short desk run. XLR is balanced, locks in place and rejects noise, so it's quieter and more reliable on stage. RCA is fine for short connections at home or between decks and a mixer.
Can I use an RCA to XLR cable on a balanced input?
Yes. The signal stays unbalanced, but it works perfectly with powered speakers and PA inputs. Keep the run under about 5m for the best results.
What's the difference between TRS and TS cables?
TRS has two black rings on the plug and carries balanced mono or stereo; TS has one ring and carries unbalanced mono. Use TRS for balanced DJ booth and interface outputs.
Which way round does an XLR cable go?
The female end connects to the output (source, e.g. the mixer or microphone) and the male end plugs into the input (e.g. the speaker or mixer channel).
What USB cable do I need for a DJ controller?
Most controllers have a square USB-B port. Use a USB-C to USB-B cable for newer laptops and MacBooks, or USB-A to USB-B for laptops with full-size USB ports. Plug straight in rather than through a hub or adaptor for a stable connection.
Can I plug my phone straight into a PA speaker?
Yes. A 3.5mm to dual XLR male cable connects a phone or laptop headphone output to powered speakers or a PA with XLR inputs. Start with the phone volume low and raise it slowly.
