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

SM Pro DJDI DI box in action at an event

31/10/2015 Leave a comment

I snapped a picture of my DJ setup at an event recently and in the bottom right corner, you can see my SM Pro DJDI DI box that was converting unbalanced, high impedance-d signals from my DJ controller and sending it to the house mixer. I utilized two channels of the house mixer for my controller but I can say that the signal was loud, clear and most importantly, not distorted. All DJs should have a DI box like this in their arsenal because it just works and people will not suffer from listener fatigue.

Palmer PAN04 stereo DI box

20/09/2015 1 comment

I was taking a look at this DI box the other day and was wondering about it. It is made by Palmer in Germany and it looks to be a pretty good DI box, judging from the rave reviews that I have been reading online. Do not get me wrong…there is nothing wrong with my SM Pro DJ DI. As a matter of fact, it is functioning great. But in my line of work, I have to check out what other companies offer

I have no idea what transformers are installed in this DI box but I have been led to believe that Palmer makes their own transformers. German engineering at its best I feel. It is three times the cost of my current DJ DI but being made in Germany, and I trust “zee Germans” for most of their stuff. Do not get me going on about Volkswagen Golf gearboxes…that is all. According to their website:

The PAN-04 consists of a housing containing the equivalent of two PAN-01s, making it a dual channel passive DI box. This „stereo” configuration makes it ideally suited for use with certain keyboards and devices which have several outputs.ive DI box. Jack input with parallel „THRU” output, transformer balanced XLR output. Attenuable input sensitivity, can handle both line level and speaker level signals.

I am seriously thinking of getting one in the future to augment my current SM Pro DJ DI. The price is not too bad too!

ROLLS DB24 Stereo Direct Interface

13/08/2015 Leave a comment

Just the other day, a month back, I came across this very nice looking DI box for sale in a forum. The seller was asking $70 for it. It looks pretty good, what with the connections that this box is able to take, anywhere from a 1/8″ stereo mini phone jack to a pair of RCA inputs. I must say that I am stoked to see a DI box with the works, even with a set of attenuators, just like the SM Pro DJDI one I bought two years ago. This is what ROLLS says on its website about this wonderful-looking product:

Introducing the new DB24 Stereo Direct Interface. This unit is a two channel isolation device designed to connect high impedance devices to low impedance. The unit is completely passive, and utilizes Rolls proprietary audio transformers for superior sound. A heavy-duty steel chassis was chosen to provide maximum reliability when used in demanding live sound reinforcement applications. A variety of inputs are provided including stereo and mono 1/4″, stereo RCA, and stereo 1/8″ (3.5mm). The DB24 is an ideal impedance matching device for connecting any unbalanced stereo signal to a balanced system. Consumer audio equipment such as CD players, DVD players, MP3 players, etc., may be easily connected to a professional audio system.

Looks pretty good. If it was not for the fact that I already have a great stereo DI box in the SM Pro, I would snap this up.

SM Pro DJDI DI box

07/09/2013 7 comments

I think I have found my ideal direct-inject (DI) box. This is the one. It is a stereo DI box or you can use it as a dual DI box for dual inputs. I installed this in a club today and I must say this SM Pro lives up to its reputation…nice and clear and I might add, punchy sound. And all this is going for about $45. According to their website:

DJs, keyboardists, computer musicians take note: The direct box you’ve been waiting for is here! Sporting two channels, the DJDI easily and inexpensively solves the problem of converting unbalanced signals into balanced output suitable for use with mixers, PAs, recording consoles, and more. Continuously variable rotary input signal attenuator allows the DJDI to accommodate virtually any source signal level; passive design means clean, quiet, uncoloured operation with no power required.

Yep. This is the one for me.
