8.4.1 Read before use
The Analogue TDcontroller is designed to be used with its proper set of speaker cabinet. They are not
interchangeable. 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 2
frequency bands (PS and dedicated SubBass system)

Active protection of the cabinets by dynamic audio signal processing (Temperature and
Displacement 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 Panel
Most front panel functions and indicators are located inside 2 distinct windows: left-hand areas relate to
functions and indicators dedicated to the optional Sub-bass section, while right-hand window contains
indicators
concerning servo control operation for the PS cabinets.
For more technical details about servo control operation and internal electronic processing, please refer
to section “TDcontroller REFERENCE GUIDE.” Page 53.
Turning the LS channel Overlap / Crossover
Pushing the CONFIGURE button
modifies the high pass filtering. It
does not affect the sub output, which
will always be a filtered sub signal.
(This is therefore not a Sub on/off
button). In the « Overlap » position,
PS is exploited to its maximum
capability.
This position should be used if the system is being used without a Subbass. It can also be used with the
Subbass; In this case, there will be a boost in the crossover area. The « Cross over » position is
generally recommended when using the Subbass.
