Page 50/82 NEXO A NALOGUE PSTD C ONTROLLERS8.4.1 Read before useThe Analogue TDcontroller is designed to be used with its proper set of speaker cabinet. They are notinterchangeable. Its main functions are:• To optimize the response of the system• When operating with the SubBass system (optional), splitting the stereo (2 channel) signal into 2frequency bands (PS and dedicated SubBass system)• Active protection of the cabinets by dynamic audio signal processing (Temperature andDisplacement servo control)• Reduction of amplifier overload (Peak limiter function)Analogue TDcontrollers also feature:• Stereo operation (2 independent channels) for the main system• Global switchable output level• Adjustable level on the SubBass channel• High CMRR input stage and High current drive output• Compensation of power compression effects on the system response curve.The Analogue TDcontroller is designed to be inserted between the Audio source (console, preamplifier,etc.) and the power amplifier.8.4.2 Front PanelMost front panel functions and indicators are located inside 2 distinct windows: left-hand areas relate tofunctions and indicators dedicated to the optional Sub-bass section, while right-hand window containsindicators concerning servo control operation for the S12 cabinets.For more technical details about servo control operation and internal electronic processing, please referto section “TDcontroller REFERENCE GUIDE.” Page 53.Turning the LS channel Overlap / CrossoverPushing the CONFIGURE buttonmodifies the high pass filtering. Itdoes not affect the sub output, whichwill always be a filtered sub signal.(This is therefore not a Sub on/offbutton). In the « Overlap » position,PS is exploited to its maximumcapability.This position should be used if the system is being used without a Subbass. It can also be used with theSubbass; In this case, there will be a boost in the crossover area. The « Cross over » position isgenerally recommended when using the Subbass.
