EQ-3231 double 31 segment pattern equalizer


● It is equipped with independent high-pass filter and low-pass filter to cut off excess frequency to reduce power consumption. Independent gain range switching key is convenient for different needs. Due to structural reasons, different sites have different frequency propagation characteristics, which are closely related to the objective volume of the site, materials and furnishings; ● Different materials have different degrees of reflection and sound absorption, and the reflection and sound absorption of sounds of different frequencies are also different, resulting in uneven transmission of the site, and even howling due to standing waves, which requires an equalizer;

    It is equipped with independent high-pass filter and low-pass filter to cut off excess frequency to reduce power loss, and independent gain range switching key is convenient for different needs. Due to structural reasons, different sites have different frequency propagation characteristics, which are closely related to the objective volume of the site, materials and furnishings;

    Different materials have different degrees of reflection and sound absorption, and the reflection and sound absorption of sounds of different frequencies are also different, resulting in uneven transmission of the site, and even howling due to standing waves, which requires an equalizer;

    Equalizer can be generally divided into the following sections of adjustment: 20Hz-60Hz. This section of frequency often gives people a very loud feeling. For example, thunder is a strong feeling in music. If it is raised too high, it will be turbid. 60Hz-250Hz, this frequency includes the fundamental tone and the main tone of rhythm tone type, which forms the balance characteristic of timbre structure. The strong tone is full, the weak tone is thin, and the strong; 250Hz-2KHz part, which includes low frequency overtones and low pan harmonics of most musical instruments; 2KHz-4KHz part, this frequency belongs to intermediate frequency, if it is raised too high, it will cover up the identification sound in the speaking voice, resulting in slurred speech; KHz-5KHz part, which is a frequency band with telepresence, affecting the clarity of language instruments; 5KHz-16KHz part, this frequency band controls the brightness, clarity and brightness of the sound;

    The setting of the equalization bypass switch, whether the 30MM equalization fader is used, and the high-precision middle device that can be locked in the middle make your adjustment in any frequency band truly become a higher professional control;

    The cut-in delay electronic switch can avoid sudden sound, each section can be improved and attenuated by 12dB, the signal-to-noise ratio better than dB is lower than 0.003 of total harmonic distortion, the safer external power supply completely eliminates AC interference, and the maximum practical starting point is from the user's safety, starting from the product itself as much as possible, and reducing potential electrical hazards;

    The biggest feature is a feedback howl indication function. When howling occurs, the LED of the corresponding frequency is lit, which is very convenient to use.
