Thanks to its central mixer section, the CDM-4000 offers great command with 2-band EQ, Gain Control and an array of inputs and outputs for connecting external tools like monitors, microphones, amplifiers, headphones and recording devices.

What case would fit the cdm4000?
A shopper on Nov 1, 2017
BEST ANSWER: I bought a case thru PSSL. I think it's a Gemini case, especially made for this unit. I actually had to talk with a rep @ PSSL & they found it for me. I will say everything about it is great - except the back panel plug ins are a little close & it takes a bit of maneuvering to get the plugs in place. I actually drilled the 2 holes for my XLR plugs & I put a strip of thin foam under the two sides of the unit. But it's perfect for travel for the unit !

Great Mixer Combo
Pros: Very portable,easy to use,Good price,Versatility,Lightweight
Cons: Usb No Song Titles

I've been a mobile DJ for 16 years and I've used this mixer the last couple of months for all of my special occasions which primarily consist of weddings, birthday parties, and corporate events. It's very easy to use and it works well with laptops, iPad, CDs, and USB flash drives. The only negative thing I have to say about it is the fact that the USB drives do not display track titles which can slow you down if you're trying to mix, which is why I only gave four stars. I basically use my iPad and laptop with this mixer and it definitely gets the job done for me. It's very easy to transport and it looks sharp. I plan on purchasing another one to use with my second setup in the very near future. Great mixer and great price, especially if you're on a tight budget.

Gemini CDM4000
I had a different player and a cd tray doesn’t work anymore. Unfortunately I don’t have the warranty because it was given to me. I’ve used my Gemini player and I love it. The only 2 bad thins that I see is that when you hook up a flash drive to the usb connection you have no control over what song is next. It would be nice if you can choose what you play instead of having to browse until you find what you want. The other is when you try to fast forward to the right part of the song you want to start it takes a long time. I would buy the next version if that can be an option.

Product review
It would be nice if there was another model similar with a jog wheel time to better and had some sound effects would buy it in a heart beat. a very good product, durable, lightweight and easy to move. Perfect for a mobile DJ set up. However the only downfall is a lack of sound effects and abilities to truly scratch.

Great CD/ MP3 player
I purchased the Gemini CDM 3700-G back in 2009 and it still works like the day I brought it. Great price, well made unit. I still use mine every now and then. This unit can be used as a stand alone or with Serato, Mixvibes, VDJ, etc... great for back up unit. I do recommend a case for this unit.
