Lo-D HGE-6500

Commentary

This is a 10-band graphic equalizer that allows you to freely control the sound quality according to the condition of the room and the preference of the sound so that you can enjoy making your own sound.

For the center frequency, the audio frequency band is divided into 10 bands with 1 octave intervals using 1 kHz as the reference frequency, and sound quality control is possible.

The conventional coil type has disadvantages such as that the electrical characteristics change depending on the quality of the material, the coil size becomes larger as the frequency decreases, and the dynamic range changes when the iron core is small.
For this reason, a semiconductor inductor with a large dynamic range is used in the resonance circuit to realize a performance with a large dynamic range over the whole circumference fraction.
In addition, an IC (HA-1457) is used for the flat amplifier which is important at the same time as the resonance circuit.

The level control of the slide-type volume is continuously variable within ± 10 dB at each center frequency.

Built-in muting circuit.

Equipped with an equalizer switch.
