HORN SPEAKER
To operate the product according to the EN 54-24 standard, an equalizer has to be inserted into the signal path, which has a
frequency response as specified in the following table.
Since horn type speakers should not be driven with full power below their low end response, adding a high-pass filter 200
Hz/-3 dB with a 6 dB/octave slope is recommended (shelving filter).
