Amplifi er Considerations
The TFM series loudspeakers are optimized for use with the LAB GRUPPEN PLM+ series amplifi ers or LAKE LM series controllers used in combination with
LAB GRUPPEN FP amplifi ers. A full range of DSP settings to suit any confi guration are provided for download on the TURBOSOUND website. The use of
third party amplifi cation and processing is only advised using the matrix of manual settings as well as the limiter calculator provided on the TURBOSOUND
website. TFM series loudspeaker enclosures should be driven by high quality power amplifi ers designed for true professional use. Power amplifi ers should
be capable of delivering long term broadband power equal to half the loudspeaker’s peak power rating at its stated nominal impedance. The use of
underpowered amplifi ers must be avoided as heavily clipped signals can cause permanent loudspeaker damage. Limiters, crossovers and equalisation
points must be set in accordance with the settings provided on the TURBOSOUND website. This will ensure the optimum sound quality and long-term
reliability as well as protection from damage.
Neutrik speakON NL4 locking input connector(s) are provided, allowing options for input and link, passive, and bi-amp operation.
