Comments about Numark C3USB DJ Mixer with USB:

I liked the faders, they felt like pro equipment. The EQ was ok I would have prefered a graphic eq. When you plug in your computer the levels are very low, I had to jack the sliders way up to hear anything compared to the analogue inputs. Maybe I'm doing something wrong, I don't know but I had the Behringer USB mixer and the USB input was nicer and the level was the same as the analouge. I wished the Behringer had two USB inputs I would have never returned it.

The Numark is a great mixer; they know how the pro works in today's world I would buy it for the price. I will be buying a VJ mixer in the future I'll be using the current mixer for it's USB inputs since the VJ mixer doesn't have this. Buy this mixer if you want to get into the DJ game with limited money. 1 Luv...
Nice Faders:
Could have included some DAW sofware for recording to your computer.
Good value for the money

Hissing and Hum

By Robert Smith

from Ohio

Comments about Numark C3USB DJ Mixer with USB:

I love this mixer except for the hum and the hiss I get from it. I have no computer hooked up to it yet and it is noisy. I thought the USB wouldnt do this but I guess I was wrong.

Mixer has a hum, do not buy

By Steven Marimberga

from Undisclosed

Comments about Numark C3USB DJ Mixer with USB:

I have a complete new system with this mixer as now the Achilles heel. The low hum is present with nothing turned up. I have tried ground lifters, new cords, and even a different mixer. The hum is only present when I use this mixer. I have all new Mogami speaker cables running to QSC kw151. Absolutely no hum without the mixer, but a hum when the mixer is connected. I sent it back for service, and the same sound when I get it back. The service department did not fix anything. Also, you can hear the movement of the main slider in the speakers, even if nothing is on. Still sounds the same after the service. Another note, is that I tested this mixer with no audio components plugged in and just the mixer to the speakers. The hum is present. When I disconnect the mixer and turn up the gain on the powered speaker, not hum or his. This is a low audio quality mixer in my opinion. I took a risk thinking it would be good, because I wanted to run two laptops via USB. I learned my lesson and I am asking for a full refund for a defective product that they can not fix. I would not waste your money on this mixer. Purchase a Denon, it cost more, but it works.
Love the idea of connecting two laptops via usb
Build is good, but the hum is not
Good price, but it does not work

Dont buy this if....

Comments about Numark C3USB DJ Mixer with USB:

you plan on trying to use 2 laptops at once via usb. I bought this to replace another numark usb mixer that was giving me problems when i had 2 laptops connected, and this one does the same thing brand new from the box. As soon as you connect a 2nd laptop, it starts squealing, hissing , and popping. I have a message into numark tech support and if they have a solution, i will update this review. I'm concerned though that this is an inherent issue with their usb mixers.

Great Mixer

By Dave. S

from Modesto, Ca

Comments about Numark C3USB DJ Mixer with USB:

This is a great mixer for the price. I would say more than likely the person who rated this earlier that was having audio problems. Had a ground loop issue coming from his laptop power supply. Something that can be found out simply by unplugging the power supply of the laptop when checking out. If that is the case the HumX is fix that problem. Totally a laptop issue not a mixer problem
