Lowpass Filter - Signat FURY 400 2x65 W Bedienungsanleitung

4.3.5 Filter
If the FILTER switch is shifted to 'LPF', the input signal will pass the low pass crossover. If the
FILTER switch is shifted to 'FLAT', the signal will not pass the low pass crossover.
If the FILTER switch is shifted to 'HPF', the input signal will pass the high pass crossover. If
the FILTER switch is shifted to 'FLAT', the signal will not pass the low pass crossover.
When the input signal has been already filtered in an earlier stage (e.g. subwoofer output of
the head unit or another amplifier), this switch has to be shifted to the 'FLAT' position.
4.3.6 Highpass filter
Only the higher frequencies can pass, if a high pass filter is chose.
Move the FILTER switch into HPF position to use this filter. The crossover frequency (HPF) is
variable from 50 Hz to 250 Hz and can be individually adjusted. Turn CW to set to a higher
frequency, CCW to set to a lower frequency.
4.3.7

Lowpass filter

The low pass filter passes the deeper frequencies only.
Move the FILTER switch into LPF position to use this filter. The crossover frequency (LPF) is
variable from 50 Hz to 250 Hz and can be individually adjusted. Turn CW to set to a higher
frequency, CCW to set to a lower frequency.
4.3.8 Power indicator
The LED indicator at the side panel provides a visual indication of the switched on status of
the amplifier. If the LED indicator doesn't light up, the amplifier has been shut off.
4.3.9 Protection
The LED protection indicator PROT provides a visual indication of an existing problem;
therefore the protection circuitry has protected the amplifier by shutting it down. Turn the
system off and correct the problem before turning the system back on.
Thermal protection: the amplifier will shut down if its temperature exceeds a safe operating
level. The amplifier will remain off until it is cooled down to a safe operating temperature.
Take care! The exterior of the amp may get too hot to touch before shutting down.
Overload: the amp will shut down if the electrical current demands exceed a safe level (this
can be caused by too low impedances or by an incorrect input level adjustment).
Short circuit: the amplifier will shut down due to a short circuit condition (this can be caused
by a poor insulation, by a damaged voice coil etc.)
D.C. offset protection: the amplifier will shut down due to an unsafe DC offset condition at
the amplifier output. Further damage of speakers will be avoided.
