LINKING OF INPUT SIGNAL TO AMPLIFIER
The Cutoff and Crossover Filters
The amplifier incorporates:
–
high-pass fourth-order cutoff filter (signal slope
–
2
4 dB/oct.);
–
fine-adjustable second-order low-pass crossover filter (signal slope
–
1
2 dB/oct.).
The high-pass fourth-order cutoff filter is used for elimination of signal LF components
which cannot be reproduced by the speaker system.
The basic model has the high-pass cutoff filter set to 45 Hz.
The low-pass crossover filter is used to limit the amplified frequency range to be
compatible with the subwoofer application.
The cutoff point of the low-pass filter can be set by the control knob within the range
of 80 Hz to 350 Hz.
Built-in Parametric EQ
The EQ provides the parametric correction of the amplifier frequency response.
The correction is effected in three points with adjustment of the respective Q value and
boost/cut parameters. The EQ is preset by the manufacturer as requested by the customer.
The customer-required parameters are shown on the label pasted on the amplifier
casing.
