Turning the LS channel Overlap / Crossover
This position should be used if the system is being used without a LSub. It can also be used with the
LSub; In this case, there will be a boost in the crossover area. The « Cross over » position is generally
recommended when using the LS400.
Adjusting the LSub level (Sub Level)
The potentiometer adjusts the level of the LSub
channel, a range of 12 dB allows a variety of
configurations and application conditions to be
accommodated. Center position of the knob is
calibrated for 1 LSub used with 2 distant PS.
Amplifier & Protection indicator
The bicolor green/red AMP LED indicates signal
presence at the sense input of the concerned
channel, allowing visual confirmation of the return
connection of the Sense cables from the amplifier
output. The LED is flashing red, when the Peak
limiter is acting, reducing excessive peak voltage or
levels capable of overloading the channel amplifier.
The yellow VLF LED indicates that displacement
protection for the LSub are engaged on the SubBass channel. The temperature protection is not
monitored.
On each side of the PS main system window, yellow TEMP and DISP LEDs indicate when protection has
been activated (temperature or displacement control) for the LF (the HF drivers temperature protection is
not monitored).
Peak Limiter adjustments
The Analogue TDcontroller features two independent peak limiter trims (one for the LSsub amplifier
section, one for the PS amplifier section), which allows the peak limiter to be set to limit the maximum
power of the amp (without affecting the protections threshold). The peak limiter has no real cabinet
protection functions; it must be tuned to avoid overdriving the amp that in turn can generate obvious
clipping noise.
To set the peak limiter to the correct value, either turn the trimmer clockwise until the red LED lights at the
same time as the amp's clipping LED, or use the graduation (power value given for 8 load).

Pushing the CONFIGURE
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, the PS is exploited
to its maximum capability.
