Modified Denon DN-X300

When I was looking to purchase my first deejay mixer, I intended to find a durable, high quality unit that I could use for both scratching and club music. The Denon DN-X300 was a perfect choice; not only was relatively inexpensive compared to other 10 inch, 2 channel mixers, but it also had all the features I was looking for (3 band EQs, AUX input, mic channel, and adjustable crossfader curve). I ordered it new from, a fantastic site for discount deejay equipment.

After doing some research on the Denon DJ forums here, I learned about the "paperclip mod", a clever way to fix the fader lag by wrapping each fader posts with a paperclip. The first step is to remove all the knobs and fader caps from the mixer, and unscrew the faceplate as shown here.

Next, the fader is removed from it's metal retention bracket. It simply unplugs from the mainboard.

The DN-X300 uses a Penny & Giles fader, which is a nice step up from standard VCA faders in terms of feel and quality. The paperclip is bent and cut to fit snugly around each fader post.

With the paperclip mod completed, the fader is reconnected and placed back inside the mixer.

With the mixer opened, I decided to modify the source select switches as well. By bending back the metal tab (as done on the switch on the left), you change them from 2-way "phono-line" switches to 3-way "phono-line-mute" transform switches. This allows you to transform the line inputs on and off just like a Rane TTM-56 (or similar).

A final photo with the mixer re-assembled. It works great, and the mods have greatly improved the scratch performance of my sets!
