    Inputs and outputs can be routed in multiple configurations to meet any requirements. The LMS206 can be controlled or configured in real time on the front panel or with the intuitive PC/Mac GUI accessed via the USB interface. Software upgrade for CPU and DSP via PC keeps the device current with newly developed algorithms and functions once available.

    Do not connect the unit to your computer before installing the software and the USB Driver. Please refer to installation instructions in this manual. When connecting the LMS206 to the amplifiers, mute the DSP outputs (or turn down the amplifier’s volume knobs) until you configure your processing. Loudspeakers may be damaged due to a wrong setup.

  • Page 11 May2019 4.6 Diagram of a typical setup With illustrative purposes, a diagram of a LMS206 working as audio manager in a typical setup is shown above. The audio processor is used for splitting the stereo signal coming from a mixer in two zones for different public. In fixed setups, is common that these two zones have different acoustical properties so different audio gear is expected.

    LMS206 May2019 11 ANNEX For bell parametric filters (PEQ), the bandwidth definition differs among the different DSP manufacturers. For this reason, it is difficult to successfully copy filter settings between different processors. The frequency span of the filter is defined by either the bandwidth or the Q factor.
  • Page 29 The dB/2 method always sets the bandwidth as one-half of the peak gain, so the definition works no matter what the peak gain is. Amate Audio LMS206 uses the dB/2 method, because it keeps the bell shape independent from the peak gain.
