How To Clean and Maintain Your DJ/Audio Gear
How to Fix Cable Connection Problems
Faulty cables are a common culprit behind DJ equipment troubles, and they can quickly derail a well-organised event. A damaged XLR cable or a loose RCA connection might seem minor but can turn into a major hassle. The upside? Most cable issues give you a heads-up before completely failing.
How to Spot Bad Cables
If you’re noticing sound cutting in and out or audio only coming from one side, these are telltale signs of cable trouble. Such issues often stem from individual wire strands breaking due to physical strain or improper coiling. For example, moving or adjusting the cable might make the problem worse, causing the music to drop intermittently.
More severe damage can lead to total signal loss or one speaker going silent. Before blaming your mixer or other gear, double-check your cables – they’re often the root of the problem.
Changes in sound quality are another red flag. If your music starts sounding thin or loses its clarity, it could mean a shield strand is shorting to the hot or cold connector. This might make the audio feel like it’s missing its punch, even if the cable still looks intact.
Buzzing, crackling, or other noise issues can vary depending on the type of cable. For instance, unbalanced analogue cables like RCA connections may buzz loudly if the signal touches the ground during setup. Cracks and pops often point to damaged connectors that allow dirt or moisture to creep in.
When it comes to digital cables, the behaviour is different. Instead of gradual sound degradation, a broken digital cable will typically cause a complete signal loss. If your digital connection is still working, the cable is likely not the issue.
How to Fix or Replace Cables
Before diving into repairs, always unplug the cable from all devices to avoid any risk of shock or injury. You’ll need some basic tools: pliers, wire strippers, a heat gun (or hair dryer), heat shrink tubing, and a soldering iron with solder.
- Locate the damaged area. Inspect the cable carefully to pinpoint any visible damage. Use pliers to trim away the faulty section, leaving clean wire ends. If this leaves the cable too short, cut a replacement section to bridge the gap.
- Prepare the wires. Slide a piece of heat shrink tubing onto each wire end before you start. Strip about 1–2 cm of insulation from each wire using wire strippers, then slightly fray the exposed copper strands.
- Reconnect the wires. Match and twist the corresponding wires together – for audio cables, this means left to left and right to right. Solder the twisted connections to ensure a strong bond.
"For analog audio, soldering is an absolute must, otherwise the quality will degrade quite a bit"
– Yatri Trivedi, Backend Developer, Pythonista, and Linux Enthusiast, How-To Geek
- Secure the repair. Heat the soldered joint and apply solder to solidify the connection. Slide the heat shrink tubing over the repaired section and use a heat gun to shrink it tightly – this usually takes 10–25 seconds.
Following these steps can restore your cable’s reliability and keep your setup running smoothly.
How to Prevent Cable Problems
Preventing cable issues is far easier than fixing them, especially in Australia’s humid climate where moisture can cause corrosion and other damage. Taking a few simple precautions can save you from last-minute headaches.
- Use the over-under wrapping technique for coiling cables to avoid kinks and strain. Store them in a dry, well-ventilated area, and transport them in dedicated cases or bags to protect against moisture and physical stress.
- Stay organised. Use cable ties or Velcro straps to secure cables without overtightening, and leave service loops near connections to reduce tension. Labelling cables with coloured tape or tags can make setup quicker and help identify faulty ones in a pinch.
For outdoor events – especially during Australia’s wet season – go the extra mile. Use waterproof cable covers, avoid running cables through puddles or damp areas, and wrap delicate connectors in bubble wrap or foam. Never stack heavy equipment on top of your cables, as this can cause permanent damage.
Regular checks are also essential. Inspect connectors for cracks, look for cuts or kinks in the cables, and test all connections before each event. If a cable shows even minor signs of wear, replace it. It’s a small step that can prevent equipment failures during crucial moments.
How to Fix Faulty Faders and Knobs
Faulty faders and knobs can throw a DJ set into chaos without warning. Unlike cables, which often give you a heads-up before failing, issues with faders and knobs tend to creep up quietly but can be just as disruptive.
Faders often show signs of trouble through crackling noises, sudden signal drops, or complete failure. You might notice problems like audio bleeding from the muted side, sound cutting in and out during scratching, or panning issues where one speaker channel disappears when the fader is fully open.
Knobs, on the other hand, might feel loose, too stiff, or act unpredictably when adjusting EQ or gain controls.
The root of these issues often lies in the type of fader technology. Traditional carbon-track faders work by running the audio signal through a sliding contact on a graphite track, which can accumulate dust and grime, leading to poor contact. Magnetic faders, like those using Rane or Pioneer Magvel technology, rely on optical or magnetic systems to detect position, making them better suited for heavy use. Regular maintenance is essential to keep fader technology functioning smoothly and prevent unexpected failures during your performance. Let’s dive into how to clean and maintain these components to keep them in top shape.
How to Clean and Maintain Faders and Knobs
Before rushing to replace a faulty fader or knob, a proper cleaning might bring it back to life. Regular cleaning is especially important in Australia’s often dusty and humid environment.
Start by gathering the right tools: an audio-grade contact cleaner, lint-free microfibre cloths, and a can of compressed air. Avoid using household cleaners or water-based solutions, as they can damage sensitive electronics.
For faders, make sure your mixer is powered off completely. Remove the fader caps – some simply pull off, while others may need a gentle twist. Spray a small amount of contact cleaner into the fader slot, then move the fader back and forth several times. Allow the cleaner to evaporate fully (this usually takes 10–15 minutes) before putting everything back together.
Knobs follow a similar cleaning process. Remove the knobs (check for set screws if they don’t pull off easily) and clean the shaft using contact cleaner and a cotton swab. Rotate the shaft to ensure the cleaner reaches all contact points and clears away any visible grime.
To extend the life of your mixer’s components, make preventive maintenance a habit. After every use, wipe down your mixer – especially if you’ve been in a smoky or dusty setting. Store your gear in padded cases to protect it from damage and avoid sudden temperature changes that could cause condensation. A monthly deep clean, paired with a maintenance log to track service dates, can help you catch small issues before they escalate.
If cleaning doesn’t solve the problem, it may be time to replace the damaged parts.
When to Replace Broken Parts
If cleaning fails to restore performance, replacement is the next step. Persistent crackling, audio bleed, or unresponsiveness, even after thorough cleaning, are clear signs that a fader or knob needs replacing. For older mixers with multiple failing components, it might make more sense to upgrade to a new unit rather than repairing each part individually.
A practical rule to follow is the "50% rule": if the cost of repairs reaches half the value of the mixer, it’s usually more economical to replace the entire unit. This is particularly relevant for entry-level mixers, where repair costs can quickly outweigh the equipment’s worth.
Labour costs for repairs are often consistent, regardless of the mixer’s value. For high-end mixers, however, investing in quality replacement parts – especially those with warranty coverage – can be a smart choice.
In Australia, sourcing replacement parts requires some planning. While cities like Melbourne, Sydney, and Brisbane have specialised audio retailers, those in regional areas might need to rely on online stores. Aftermarket options like the Innofader, priced around $150, often provide better durability and performance.
If you’re comfortable with DIY repairs, replacing components yourself is an option. You’ll need tools such as a Phillips screwdriver, soldering iron, solder, and desoldering equipment. The process involves disassembling the mixer, desoldering the faulty part, soldering in the replacement, and reassembling the unit. If soldering isn’t your strength, professional repair services in Australia’s major cities can handle the job, often with warranty coverage for peace of mind. Taking these steps ensures your gear stays reliable, so your DJ sets go off without a hitch.
How to Fix Jog Wheels and Turntable Problems
Jog wheels and turntables are the backbone of any DJ setup, but they can sometimes throw a wrench in your performance. Unlike faders, which tend to wear out gradually, jog wheels often fail without warning. One minute everything’s fine, and the next, your scratching lags, or the track just won’t stop.
Common jog wheel problems include touch sensitivity issues, delayed responses, inconsistent movement, or even complete failure to register your input. You might experience tracks slowing down instead of stopping, stuttering during vinyl mode, or even a grinding sensation when turning the wheel.
Turntable troubles can show up as pitch drift, speed wobble, audio dropouts, or motor failures. These problems often stem from dirty contacts, calibration errors, or grounding issues with your power supply.
Modern DJ controllers are complex, and what seems like a hardware issue could just be a software glitch or an incorrect setting. Before jumping to conclusions (or costly repairs), try these troubleshooting steps.
Basic Care for Jog Wheels and Turntables
Check the jog wheel mode first. On controllers like the DDJ-FLX6, switching between CDJ and Vinyl mode (Shift + JOG CUTTER) can resolve lagging or unresponsive behaviour. For Pioneer SB3 controllers, make sure the "Vinyl" button is lit. The outer ring of the jog wheel adjusts track speed (pitch bend), while touching the top platter stops the track for scratching.
Reset your controller if changing modes doesn’t work. For example, with the Pioneer DDJ-RX, disconnect the USB, power it on while holding SHIFT + DECK 1 for 5 seconds, press SYNC on both decks for 3 seconds, and then reconnect.
Recalibrate your jog wheels to fix touch sensitivity issues. Most controllers auto-calibrate during startup, but this process can be disrupted if the platters are touched during boot-up.
"All of our capacitive touch platters go through a calibration cycle during the power on/boot-up sequence. During this calibration period (~20sec), it is recommended not to touch the platters as they are detecting/sensing various conditions of the environment and adjusting the touch algorithm as needed to provide the best experience for your environment." – addie, Engine DJ Community
For Denon Prime 2 controllers, avoid touching the platters for at least 20 seconds during power-up. If you’re using a Denon Prime 4, there’s a recalibration option in the console menu – again, keep your hands off the jog wheel surface during this process.
Fix grinding or noisy jog wheels by cleaning and lubricating them. Carefully disassemble the unit, remove the faceplate, and apply a small amount of conductive silicon grease between the ground finger and the rotary post.
"If it’s not conductive, you’ll lose your touch sensitivity on the jog wheels!" – photojojo, DJ TechTools
When reassembling, ensure the bushing is aligned and centred properly.
Test your power source and cables. Sometimes, grounding issues or interference can cause problems. Use a high-quality USB cable with ferrite cores on both ends to minimise interference.
Keep your firmware up to date. Outdated software can lead to lag or unresponsiveness. Follow the manufacturer’s instructions to install the latest updates. Along with proper mode settings, regular firmware updates are key to keeping your equipment running smoothly. If none of these steps work, it may be time to call in the experts.
When to Get Professional Help
If you’ve tried all the troubleshooting steps and the problems persist, it might be time to seek professional assistance. Persistent issues, such as motor failures or calibration errors, often require specialised tools and expertise to fix.
For major events where reliability is non-negotiable, professional DJ services can save the day. One Click Events, based in Melbourne, offers event packages that include DJ services, ensuring your celebration runs seamlessly without technical hiccups.
If your controller is still under warranty, contact the retailer or manufacturer before attempting any DIY repairs. Attempting fixes on your own could void your warranty. Be sure to document all troubleshooting steps before consulting a professional.
Professional intervention is especially necessary for internal motor problems, complex calibration errors, or multiple simultaneous failures, as these may indicate deeper electronic issues.

How to Fix Mixer Power Problems
A silent mixer can bring your performance to a halt. To get things back on track, start with the basics.
Just like checking cables and faders, ensuring your power supply is in good shape is crucial for uninterrupted operation.
How to Check Power Problems
- Inspect the power supply and adapter. A faulty adapter is often the reason a mixer won’t start. Try swapping it out with another compatible one to see if that resolves the issue.
- Examine the electrical outlet. Make sure the connection is tight and secure. Loose or unstable outlets can cause sudden shutdowns during use.
- Check the fuses. Look at the fuse in the plug and any internal fuses in the power supply. If you’re unsure how to do this, it’s best to consult a professional.
- Confirm voltage requirements. Refer to your mixer’s manual to ensure you’re using the correct voltage. In Australia, the standard is 230V. Using the wrong voltage can cause serious damage.
- Power cycle the mixer. Turn it off, wait for 30 seconds, and then turn it back on. This simple reset can often resolve minor internal issues.
- Use the same power source for all devices. Plugging all your audio equipment into one outlet helps avoid grounding problems and eliminates unwanted hum caused by ground loops.
- Watch for warning signs. Flickering lights, sudden shutdowns, or popping sounds could point to internal issues. If you notice these, contact a technician immediately.
If none of these steps work, it’s time to call in a professional. Continuing to use a malfunctioning mixer can lead to further damage. Let a qualified technician diagnose and fix the internal problems.
Maintenance Tips for Australian DJs
Australia’s varied climate creates unique challenges for DJ equipment. Whether you’re dealing with the humid tropics of Queensland or the dry heat of the Outback, your gear is constantly exposed to temperature changes, moisture, and dust. Without proper care, these conditions can wreak havoc on your equipment. Here are some practical tips to help keep your setup running smoothly, no matter where you are in Australia.
Regular Maintenance Tasks
Keeping your equipment in top shape requires consistent upkeep. Here’s how to stay ahead:
- Clean your gear monthly to prevent dust buildup, especially if you’re in arid regions. Use compressed air to clear out mixer channels, fader slots, and ventilation grilles. Dust can lead to overheating and even component failure, particularly during those scorching summer months when temperatures soar past 35°C.
- Inspect your cables every two weeks, as Australia’s intense UV radiation can wear down cable sheathing faster than you might expect. Look for fraying or cracks, especially at connection points. Store cables in protective cases and avoid leaving them in direct sunlight or inside hot vehicles.
- Lubricate moving parts quarterly with contact cleaner. In northern Australia, where heat and humidity are common, controls like jog wheels and pitch faders can become sticky or unresponsive. A little lubrication goes a long way in keeping things smooth.
- Check grounding connections regularly. Dry conditions can lead to static electricity buildup, which can damage your gear. Make sure all your equipment shares the same earth connection to avoid ground loops and electrical issues.
- Acclimatise your equipment when moving between temperature extremes. For example, if you’re going from an air-conditioned venue to a hot outdoor event, let your gear sit for at least 30 minutes to prevent condensation from forming inside.
Equipment Checks Before Events
Routine maintenance is essential, but pre-event checks can save you from last-minute disasters. Here’s what to focus on:
- Test all connections the day before your event. This step is especially critical for outdoor gigs, where backup options might be limited. Run through your entire setup, from turntables to speakers, to catch any issues early.
- Confirm power requirements with venue staff. Some older Australian venues may have inconsistent power supplies. Bring a multimeter to check voltage levels, as fluctuations outside the standard 230V range can damage sensitive electronics.
- Pack backup cables and adapters for every connection type. Australian venues often feature a mix of old and new equipment, so having RCA, XLR, and 6.35mm jack cables in your kit can be a lifesaver.
- Check the weather forecast for outdoor events. Summer storms can appear out of nowhere, so keep weatherproof covers and contingency plans handy. Even indoor venues can pose challenges if they lack proper climate control during extreme weather.
- Bring portable fans or cooling solutions for hot-weather events. Mixers and amplifiers can generate a lot of heat, and high temperatures can push components beyond their safe operating limits.
