A small USB controller for big shows

21/10/2017 Leave a comment

There has been lots of talk in BMX forums where some DJs are saying that small controllers do not look “professional enough” for big shows. If it is not the stigma that goes with smaller vs bigger controllers, they say that the sound from the small, USB-powered controllers is not strong enough and sounds weak. I am here to tell you this…bullshit. First and foremost, you, the DJ, are hired for what you can do. Small controller, big controller, it do not mean shit. Secondly, about the sound from USB-powered controllers. Well, there is a grain of truth in that. That is why I always hook up my small DDJ-WeGo through a DI box. This allows me to use the quality XLR inputs on a sound desk and my small, USB-powered controller sounds absolutely fantastic. So all the more guys…get a good DI box. It is very essential.

Alctron DI120 dual passive DI box

19/10/2017 Leave a comment

I saw this Alctron dual-channel DI box for sale on Taobao and i thought that it would be a great addition to my arsenal of sound tools. the SM Pro DJDI is still working fine but as i said before, I need to have another one in my audio rental box for use by clients. I at first wanted the DI box made by Palmer but one Palmer can buy three of these DI boxes and also if it gets abused during rental, I will not feel the pinch. I do not know what it sounds like or it’s performance, but I am willing to give it a try. Not too bad for $40.

Whirlwind PodDI

19/07/2017 Leave a comment

I have seen it too often when I am troubleshooting installs. Some idiots always try to sum two stereo outputs into one, to convert to a mono signal. Rane has an excellent article on their website  named Why Not Wye. Every installer worth his salt NEEDS to read this and commit it to memory.

If however, you need to sum a stereo output to a mono input, get one of these Whirlwind PodDIs. I have never tried nor owned this piece of equipment above but if it is from Whirlwind, I would trust it. You can always build your own and the Rane website gives a schematic diagram on how to do so. From Whirlwind’s website, this is described as:

The podDI is a single output summing direct box. Use it to connect CD and MP3 players, computer sound card outputs, DJ mixers, etc. to professional equipment with balanced inputs such as a mixing console. Accepts stereo inputs and sums them into a single mono output.

This would be a great addition to the DJ toolkit. Sometimes, you cannot always get two XLR channels on a soundboard for your controller for example. The channels all may be used up or maybe all they can spare is one channel. I might get one of these. It looks like something very useful

Extron BUC 202

06/04/2017 Leave a comment

I have an old Extron BUC 102 and it is a great-sounding “DI box” for it’s use. This is the newer model that replaced it, the BUC 202. It has the same functions at the older BUC 101, which is to convert unbalanced audio to balanced audio and vice versa. The only difference is that this model has a built-in power supply whereas the older one needed an external Extron power supply. I suppose the only thing I like about these boxes are it’s versatility in converting balanced to unbalanced and vice versa.  For all other uses, an inexpensive, passive DI box will do the job just as well.

Radial ProD2 stereo DI box

14/03/2017 Leave a comment

I have an SM Pro DJDI stereo DI box that I am very happy with. It has been through so many events with me and makes my controller sound totally great all the time. But now that it is getting old, I decided to get a new DI box for my controller. I thought of getting the Palmer stereo DI but decided to get something that sounds even better. That is when I chanced upon this Radial ProD2 stereo DI box and I think that is the next one I am going to get. According to what I got from Radial’s website:

The Radial ProD2 is a compact stereo direct box developed specifically to address the needs and challenges of interfacing a stereo keyboard to a professional audio system. This passive DI features two independent channels with separate inputs and thru-puts for the artist’s stage amp and two fully isolated outputs for the PA system.

At the heart of the design are two high performance Eclipse ET-DB2 transformers. These deliver 20Hz to 20kHz performance with less than 1.5dB deviation above 18kHz and are able to withstand tremendous signal levels without distortion. Unlike active circuits that overload when the signal exceeds the rail voltage, transformers saturate. This creates a pleasing effect that naturally rounds out the tone, acting like a subtle limiter which is particularly advantageous when interfacing the ProD2 with digital pianos, samplers and drum machines that can produce excessive dynamics. Transformers are particularly adept at eliminating hum and buzz caused by ground loops.

As with all Radial products, the ProD2 is built tough to handle the rigors of professional touring. A 14-gauge steel ultra rigid i-beam skeleton frame eliminates opportunity from outside stress to flex the sensitive PC board and cause premature solder joint failure. The innovative book-end design creates a protective zone around the connectors and switches further increasing lifespan. And a full bottom no-slip pad adds mechanical isolation and electrical insulation to further reduce opportunity for noise.

The Radial ProD2’s warm sound, legendary build quality and compact design have made it the most popular stereo direct box made today.

Radial DI boxes are legends in the audio world and I dare say that this one will suit me well. One thing I like about their transformers within the DI box is that they are encased in cases with Faraday shields. They are a little pricey but I think you get what you pay for…and that is excellent sound

Yamaha MG12XU mixer at an event

12/12/2016 Leave a comment

I was the DJ cum soundman at a wedding a couple of days back and the audio company supplied me with this mixer for the whole event. Very nice sounding mixer, like most Yamaha mixers are. Hooked up my trusty DDJ-WeGo to my SMPRO DJDI DI box, and from the outputs to input channels 3 and 4 of the Yamaha mixer and I was set for the night. I did not see the need to use the Denon DN-4500 dual CD decks as I already had my controller, even though they were hooked up to two of the stereo channels. It was a good wedding and everything went smoothly. Looks like Yamaha have really improved on their mixers.

Microphone briefcase

12/11/2016 Leave a comment

While at a gig a couple of weeks back, I happened to chance upon this microphone briefcase that was used by the audio rental company. I thought to myself that this was a novel idea, keeping all the mics and DI boxes in one box, with lots of padding protecting the microphones. I do not have that many mics but I will be getting some more when I expand my audio inventory and a case like this is what I might get.
