Commentary
Left and right independent 33 elements, stereo graphic equalizer with fine adjustment at 1/3 octave.
The 16 Hz-25 kHz band is divided into 33 left and 33 right bands, and the center frequency of each band is designed according to the 1/3 octave step, which is the basic of audio.
By adding 16 Hz and 25 kHz to the 31 bands of an advanced spectrum analyzer, the array of 33 sliders draws a frequency curve as it is.
Semiconductor inductors are used for each band filter.
It is equipped with a variable range switch that can be selectively used : ± 12 dB for large changes in frequency characteristics, and ± 3 dB for delicate characteristics.
Equipped with an equalizer position switch for easy equalization recording.
Equipped with a characteristic switch that can obtain inverse characteristics of the set frequency.
In addition to the black model, there is also a silver model.
