    Use the following type of fuse: 6.3 A 5x20 Make sure the TEX150-LCD/S switches are in the “OFF” position. The exciter features two switches: one built into the VDE base for the mains power supply cable, which cuts off mains power completely, and the second is located on the front panel and bypasses the machine’s switching power supply.

    From the “Fnc” menu, enable power delivery. 5.3 Settings and calibration The only manual adjustments required for the TEX150-LCD/S are those related to the levels and the audio operation mode. The back panel of the device features a trimmer for each exciter input; the labels indicate which trimmer refers to each input.

  • Page 12: Software

    TEX150-LCD/S To adjust the input sensitivity level, remember that the preset menu contains the instantaneous modulation level and that an indicator reads a level of 75 kHz. For a correct adjustment, we therefore recommend you apply to the machine input a level equal to the maximum level of your audio program and adjust the related trimmer until the instantaneous deviation coincides with 75 kHz.
  • Page 13 TEX150-LCD/S The bar to the right of “Mod” indicates the modulation progress in real time; the broken bar indicates the maximum nominal modulation of 75 kHz (100%).
