What is the solution when I get no sound in DJ Console MK2 headphones?

If you hear no longer DJ Console MK2 Deck A and Deck B in headphones preview mode, then you may have upgraded DJ Console MK2 drivers to the last release (2.cmk2.2007) but you have forgotten to update your version of VirtualDJ.
To restore a proper preview mode, you must
- either install VirtualDJ 3.4.1 ,
- or switch in ASIO mode (run VirtualDJ in mode "Equalization on audio inputs").

Is Mobile DJ MP3 compatible with rechargeable batteries?

You can power Mobile DJ MP3
- either with 2 pre-charged batteries (C type / LR14) (Alkaline or zinc carbon batteries)
- or with 2 rechargeable batteries (C type / LR14) (Nickel-Metal-Hydride (NiMH) or Nickel-Cadmium (NICAD or NiCd))
The only difference is the operation time, which is longer for alkaline batteries.

It is not recommended to power Mobile DJ MP3 with 1 rechargeable battery + 1 pre-charged battery since their operation times are different and their voltage are different (1.5v for the pre-charged battery versus 1.2v for a rechargeable battery).

How long can I mix with Mobile DJ with the same 2 batteries?

Battery lifetime depends on your battery model
- alkaline batteries capacity is the highest (up to 7500 mAh)
- carbon zinc batteries capacity is lower than alkaline
- rechargeable batteries have the smallest capacity (up to 3000/4000 mAH per charge, but you can recharge them).

Mobile DJ consumes over 300mA with LCD backlight on, but not much as soon as the LCD switches off.

Mobile DJ should provide continuous mixing for
- 15 to 25 hours with 2 fresh rechargeable batteries (akkus)
- 30 to 50 hours with 2 good alkaline batteries.
It may be shorter with old batteries and longer with excellent batteries.
