2. Is the audio input to the [AUX IN] and [MIC] terminals set to an appropriate level?
Set the audio level input to the respective terminals according to the connected devices.
3. Are unbalanced signals being output from the [MASTER OUT 1] terminal with a monaural cable?
With unbalanced outputs, the sound will be distorted unless the output is set to an appropriate level.

This unit’s track information may be in a language not supported by the connected DJ software. Refer to the DJ software’s operating instructions for the range of languages the DJ software supports.

Files in MP3 and AAC format support ID3 tags for embedding track information, so artist names, album names, etc., can be read out from the files and displayed. Files in WAV and AIFF format, on the other hand, do not support ID3 tags, so artist names, album names, etc., cannot be read out from them. To display the track information in this case, the information must first be edited at the “Edit” option. Note that with the Import from iTunes function, the file information in the iTunes library is browsed, so the track information is displayed even for files in WAV and AIFF format.

When the Key Lock function is turned on, key control processing is performed to keep the key constant, so the sound quality changes. This change in sound quality is normal for the product's specifications. This is not a malfunction.

The problem may be one of the following:
-There is a disconnection in the USB cable connecting this unit and the computer.
-The USB cable was disconnected while this unit's firmware was being updated. (When the power is turned on, the Deck A Loop Out indicator lights.)

If multiple USB devices (such as a mouse, keyboard, etc.) are connected to the same USB bus system on the computer or to a USB hub, Virtual DJ Limited Edition may not operate properly due to problems in the USB bus bandwidth or conflicts between the USB devices.
In such cases, changing the USB ports used for connection can sometimes improve the problem.

Virtual DJ LE does not include a function for saving samples. Samples can be saved when you upgrade to Virtual DJ Pro .

The master volume and headphones volume knobs on the computer screen cannot be operated from the controller. Normally use with the knobs set at the maximum setting (turned fully clockwise).

Are the master volume and headphones volume knobs on the computer screen set to the maximum setting (turned fully clockwise)? Use with them set to the maximum setting (turned fully clockwise).

When the 4-deck layout is set, decks [C] and [D] are not displayed on the [EFFECTS] panel.

When the same effect is selected for decks [A] and [B] and the effect is not turned on for both decks, the parameter for the opposite deck may change when a parameter operation is performed. When the effect is turned on for both decks [A] and [B], the parameter only changes for the deck that is operated.

This error message appears if Virtual DJ is launched before the DDJ-ERGO is running.
