Pros:
The DJ Console has a low latency.
Large, touch-sensitive jog wheels with which it is very possible to make transitions.
4 decks, which I have never needed.
Additional microphone jack for announcements in mixing or radio shows.
Lighting, very useful in low light conditions.
Cons:
Requires a computer to function.
No possibility to connect an external CD player or turntable.
Faders have a lot of leeway.
Bad processed Pitchfader which is is almost impossible to adjust the BPM good. Beginners use anyway the simple sync buttons.
Mediocre sound card. During normal desktop operation virtually no adjustment. Since I had just got something like NEN equalizer.
No full Virtual DJ software. Only Virtual DJ LE. (Very limited functionality)
Only a support for Virtual DJ and Traktor Pro. Programs like Magix Digital DJ 2 must be manually adjusted on the controller. Requires a lot of time and patience.
The neutral point of the EQ Poties might still have a little stronger resistance.
After 2 years of use, it is clear that there are signs of wear. When I left my volume fader completely to 0, so down, sit, then the volume and little wriggling up and down. But that's not a problem if you do not press the Fader all the way down.
My conclusion: that time for 250 Bought. Bin thus largely satisfied. For the price of 160 strong buy recommendation. As the controller is written only conditionally recommendable for professionals as well as very little effects are present and they are also not well adjusted.
