Small speaker system for sale

Continuing my general clear-out, it’s time to sell my last speakers. I used to run a sound system, and what’s for sale now was the “small” rig, or as a DJ monitor rig at larger events. It’s a bit home-brew, so I’m not expecting to get much for it, but the components are high quality and it sounds good.

The bass units

The bass units are 12″ ATC drivers that were originally specified for Hill Audio M4s. The boxes have good casters, sturdy grilles, wooden skids and can be stacked as shown above to make a neat little bass reinforcement unit. The drivers are 12Ω and wired in parallel, making each cabinet 6Ω.

They have two 4 pole Speakon connectors on recessed back plates, and the drivers are wired between the A terminals. The B terminals on both connectors are looped together. I usually drive these boxes either with one channel of a Crest Audio (CA) CA9 per box, or in parallel combined onto a single CA12 channel.

The mid-top units

The mid-top units can be pole mounted as shown above. They comprise of a Motorola Piezo and a Beyma 10″ G-200 on a passive cross over. The Beyma is an astonishingly accomplished driver, which means these little tops can be used as full range cabinets. These mid-top units present an 8Ω load.

These mid-tops also have two 4 pole Speakon connectors on recessed back plates, and the drivers are wired to the B terminals. I usually drive these boxes with a CA6.

How powerful is it

Well, technically I suppose the tops are 200W RMS each and the bins about 600W each. A CA6 on the tops can deliver 400W to each top, and a CA9 around 800W to each bin. You could probably call it a 2K system if you wanted to think about it like that.

What’s it like to use?

The rig is fairly manageable – I can pick up and stack or load the bass units by myself. It’ll all fit inside an estate car. The casters on the bins make it all easy enough to trundle around.

How much do you want?

It’s very hard to value these things. £450?

Where is it?

At my house in Woking, Surrey.

Are you selling amps / signal processing too?

I’ll probably look to sell some amps and signal processing once the speakers are sold, but shifting the speakers is my priority as I want the space.

Pioneer DJM 2000 firmware update to version 3 – nearly a Nexus!

This article details the benefits of updating the firmware on a Pioneer DJM 2000. It’ll also explain the differences between a DJM 2000 running the latest firmware, and a DJM 2000 Nexus. It should be very useful if you are trying to decide whether to buy a DJM 2000 or a DJM 2000 Nexus, or if you already have a DJM 2000 and want to better understand the benefits of upgrading the firmware.

An introduction to the Pioneer DJM 2000

I recently acquired a DJM 2000 running version firmware 1.27. It’s about 5 years old, but in good condition. Still a very nifty piece of kit. My last mixer was a DJM 500 and the game has really moved on. From a purely non-musical perspective, consider that it has a touch screen and 6 network ports!

So a four channel DJ mixer. It can support turntables on two of the channels, and all channels support analogue and digital line in. It can perform the duties of a network hub between up to four CDJ devices, and even connect to two computers for seamless transitioning between DJs at a live event. It has a send/return loop and a midi interface. There’s a huge amount of potential with all this, which I won’t go into now, but suffice to say this hardware is ready to combine traditional live DJ duties with more creative musical experiences normally restricted to audio studios.

From the top view then, this is more or less a traditional four channel mixer with an effects unit shoved in between channels 2 and 3 above the cross fader. So what does that touch screen do?

It handles administration, midi control, settings etc. At first it seems bizarre that a mixer needs this, but much as we now take games console internet updates as being completely usual these days (remember the initial weirdness of the PS3 being online?!), it makes sense. But it also allows for some live DJ uses:

7 band cross fader

Yes – chop two tracks together in seven chunks of the audio spectrum. Easy high-hat or kick drum swapping right there.

Live effects control

Use one finger to quickly control the base frequency and oscillation period of any of the built in effects.

Updating the firmware

See my guide on updating the DJM 2000 firmware. If your DJM 2000 is still running version 1.x, you’re in for quite an upgrade!

Benefits of firmware version 3

DJ benefits

  • Beat Slicer – a brilliant tool that allows the DJ to sample and remix on the fly. Great for creatives.
  • Improved side-chain effect – add a whole bunch of filters to the built-in side-chain and control these with a single finger on the touch screen. I saw a good example of this in use where the gate effect was triggered by the existing (old) track, and applied to the incoming (new) track. This fade in effect sounds great!

Engineering benefits

  • Peak Limiter – billed to “eliminate distortion and clipping even at club volumes”, that’s certainly good news given some of the DJs I’ve worked with…
  • Auto Standby – turns itself off after 4 hours of inactivity.

CDJ / Rekordbox benefits

  • Quantize effects – if you’re using Rekordbox, the mixer can use the BPM information to ensure that all the effects (including the awesome beat-slicer!) are locked in time with the underlying track.
  • Sync master – using the DJ link, the DJM 2000 can optionally enforce exact BPM matching between any or all CDJ 2000 NXS players.

What’s better about the Nexus?

All statements from here onwards assume we are comparing a DJM 2000 with firmware version 3.20 with a DJM 2000 Nexus running the same firmware. So far as I can tell, there are no feature differences. That makes sense, right? The differences must all be in the hardware.

The are some cosmetic changes. The three Effect Frequency potentiometers in the middle of the mixer have silver knobs on the Nexus. The row of beat selectors beneath them are lit by white LEDs on the Nexus (red on the Mk1). Meh.

In functional terms, the Nexus sports Pioneer’s “P-Lock” fader caps which cannot be easily removed and therefore are more likely to stay in place during enthusiastic use. Whether or not the Nexus also has the more durable fader assembly that sits at 90 degrees to the surface of the mixer so as to be less prone to damage due to spills and dust, I don’t know. Either way for studio use, neither of these advantages concern me.

The Nexus also has higher quality digital converters on its output stages. The Nexus has a 32 bit D/A converter. I can’t find that specification for the Mk1 so perhaps it is only 24 bit. Both sample at 96 kHz, have <0.004% distortion and have a 107 dB signal to noise ratio.

Conclusion

I’m entirely satisfied with my acquisition of a DJM 2000 Mk1 now that I’ve upgraded it to firmware version 3.20. The hardware improvements that come with the Nexus are mainly cosmetic, with only the improved D/A converter being something I might like – but that’s on a theoretical level; I can’t fault the sound as it stands.

I don’t have any CDJ players yet. The Sync Master feature suggests that if I do acquire some, I’m going to want to dig deep and get the CDJ 2000 Nexus players.

The whole topic of whether features like Sync Master and Quantise actually take the talent out of DJing is an interesting one. I can beat match. I’ve got a load of music on vinyl and I enjoy using my Technics. However I’m keen to focus on creating new blends and cuts. The longer I have to spend on the technicalities of beat matching, the less time and therefore enjoyment I’m going to derive from the more creative side of things. That’s my excuse for now, anyway!

Pioneer DJM 2000 / Nexus firmware update – how to

Note: I’ve done this using Windows 10 in January 2016.

Before we start here, if you want to know more about the DJM 2000 in general, take a look at my in-depth look at the mixer as a whole.

Begin by getting the mixer to display your current version. To do this, while the mixer is on, press and hold the Live Sampler button to the left of the touch screen.

Pioneer DJM 2000 version 3.2

Choose “Version Number” and it’ll display it. Naturally I didn’t take a photo before the upgrade when I was on version 1.27, but here’s the end destination – version 3.20!

Download the latest firmware updater – available for both PC and Mac. Just in case it is ever useful, I’m got a mirror copy of the Windows firmware updater for version 3.20 here.

Extract the zip file. Then we have to establish some kind of communication between the PC and the DJM 2000.

All the guides I’ve read suggest that the DJM 2000 should be connected directly to the Ethernet port of the PC you are using. Apparently it has its own DHCP server and will create a private network if you set your PC to look for a DHCP server there. I tried this and couldn’t get it to work. I’d like to think I know my arse from my elbow in that realm at least.

So instead I connected the DJM’s “Computer 1” port to my LAN while the mixer was off. I then held down both the beat effect and remix effect on/off buttons while switching the mixer on. My router accepted a DHCP request from the DJM and assigned it a local IP address. I could see that it was listening on port 58003. The mixer’s display said it was waiting to receive an update.

Then I ran the executable file in the downloaded zip file. I permitted network activity on any network to that application. It detected the mixer and uploaded the new firmware. The mixer presented a bar chart on its display which tracked progress.

DJM 2000 firmware update

After that, I turned it off and on again as instructed, and hey presto! Version 3 was loaded.

Now you’re on the latest hardware, I bet you’re wondering what you’re missing out on by not having a DJM 2000 Nexus! The difference might not be as great as you’d expect. Check out my summary of the situation.
