Please observe the following advice. correct wrong Illustration 4.1: Speaker stand insertion Slightly raise the speaker as shown in Illustration 4.1, this will enable you to align the angle. Take care: if lifted to high, the speaker will be taken out of the flange and thus be loosened! After lowering the speaker down ensure the flange locks in place.

  • Page 12: Avoidance Of Ground-Loops

    4.2.4 Avoidance of Ground-Loops If for instance two audio components bearing a different grounding potential are connected, low- frequency interference currents may superimpose a voltage drop on the audio signal. These dif- fering ground potentials may stem from the individual earthing of each component. The interfer- ence signal will appear with the magnitude of the difference between the grounding potentials.

  • Page 13: Connecting Sources And Setting The Input Sensitivity

    4.3 Connecting sources and setting the input sensitivity The VL3x0 features universally usable inputs. Depending on the intended application, e.g. micro- phones or Keyboards the individual channel sensitivity is set by the illuminated mode buttons (2) and (5) (→ see Illustration 2.2). At the same time this setting also tailors the sound control impact to the connected source (e.g.
  • Page 14 Connection possibilities and input modes This section explains the modes and properties of the individual channels. Channel 1 Mode „MIC“ • → Suitable for microphones and low level sources This mode offers a maximum gain of 50 dB which can be set via the channel volume control. Mode „P48“...
  • Page 15 Channel 2 – Instrument / Line / Mic Though Channel 2 offers universally usable inputs its key function is instrument and line-level amplification. For this purpose it is equipped with two 6,3mm jacks. As the gain of XLR I ranges up to 20 dB the amplification of most standard microphones is also feasible.

    5.1.7 Usage of playlists Playlists have the form of text files and define the playing order with line-by-line file names with or without path destination. The format “.m3u” and “.pls” is supported. If provided a playlist in the current playing folder the USB player will exclusively access its playlist items, thus remaining files in this folder and its sub folders are skipped.

    5.1.8 Folder change when using playlists If you trigger a folder change while a playlist is active the next folder starting from the path of the playlist is being accessed. This way you may skip the remaining playlist items. 5.1.9 Creating playlists When creating playlists please make sure the path destinations match the actual folder structure of your USB storage device.
