Mobile DJ communicates with its USB dongle in a proprietary 2.4 GHz protocol: it uses neither WIFI nor Bluetooth. Mobile DJ proprietary protocol operates at a base frequency of 2.407GHz, and when it detects noise in its frequency, it moves by steps of 250KHz to the next noise free frequency channel.
The dynamic frequency adjustment lets Mobile DJ adjust to 2.4 GHz wireless networks (WIFI, Bluetooth) so that
- Mobile DJ doesn't interfere with wireless networks,
- and the wireless network doesn't interfere with Mobile DJ.
You should place Mobile DJ USB dongle at 2 feet or more from any other 2.4 GHz transmitter (WIFI, Bluetooth or audio/video proprietary transmitter) to get a good transmission range, since if they are closer, both systems will continuously jump from 1 frequency to another to avoid each other disturbance, and such continuous channel changes reduce the transmission range.
For the same reason, you should place a WLAN device at least 2 feet away from another 2.4 GHz device (Bluetooth, audio/video transmitter..) to optimize the range of your WLAN network.

MegaSeg is a DJ mix software in Mac OS.
1) In MegaSeg, if you use the Discrete Output Mode, and select both Hercules outputs using the Aggregate device output, then you can use DJ Console MK2 headphones selector to select the various cue modes.
2) But MegaSeg default mode is different, since instead of the left and right decks being hardwired to one output, MegaSeg has a "Preview" button to route either deck to a 2nd output for cueing or previewing. In this mode, both decks would output to a single output device (on a single stereo channel), and then you can press Preview and switch either deck to a 2nd output to cue (like the built-in headphone jack). This function is mapped to the cue button on the DJ Console MK1, and now the Audio source select on the DJ Console MK2. As the audio source select is also on this button, it means you must push this button twice to toggle the Preview mode.

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").

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).

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.

Mobile DJ Mix software includes an AutoCue function in the analysis of the sound track to :
- define a Cue In point (Cue In = the moment where the song playback starts in a DJ mix, which is the moment where the software detects a regular beat)
- define a Cue Out point (Cue In = the moment where the song playback ends in a DJ mix, which is the last point where the software detects a regular beat)
The analyzes of the Cue In / Cue Out point is in general
- relevant for music with a fixed beat and for dance / techno / country / rock music,
- irrelevant for music with changing rhythms, as for example classic music, pop songs starting with vocal solos, slow electronic music and in general music whose rhythms are far from techno/dance...
The solution for the music tracks with bad cue points is for the user to define one's own Cue In / Cue Out points:
1) load the music file
2) browse in Mobile DJ Mix software (with the slider over the waveform) at the point of the waveform where the user wants to place the Cue In point
3) Click on the "In" button of Mobile DJ Mix software on the deck where the song is loaded (left and right of Automix button on the software screen), to define the point which will be the Cue In point,
4) Click on the button with a triangle down on Mobile DJ Mix software to set the Cue In point,
5) browse in Mobile DJ Mix software (with the slider over the waveform) at the point of the waveform where the user wants to place the Cue Out point (the end of the music playback)
6) Click on the "Out" button on the deck of Mobile DJ Mix software where the song is loaded (left and right of Automix button on the software), to define the Cue point will be a Cue Out point
7) Click on the button with a triangle down on Mobile DJ Mix software to set the Cue Out point
8) Once the Cue In and the Cue Out points have been saved for the music track, save the Playlist with the button "Save".
If the user doesn't save the playlist after changing the cue points, the new cue points won't be saved.
