SONY SEQ-555ES

Commentary

This graphic equalizer is equipped with an automatic sound field correction function and can create a sound field reference with one touch operation.

Equipped with an automatic correction function that measures up to 16 points of the frequency-response at the microphone location using the attached microphone and the built-in ピクノイズ generator and makes it flat (average value).
You can store up to four types of characteristic patterns. You can store up to four types of characteristic patterns that are adjusted according to your favorite sound quality or genre such as vocals, jazz, and pops.
Memory can be called up with one touch.

It is equipped with a real-time analyzer display, and the sound energy of the sound field picked up by the microphone is divided into 10 bands when the sound field is corrected, and the sound energy of both the left and right channels of the program source is divided into 10 bands when the equalizer is corrected, and the levels are displayed on a bar graph.
The display range is 13 steps from -60dB to 14 dB.

The left and right independent 10-band electronic equalizer uses a newly developed ASP-IC and allows accurate equalization by simply pressing the UP-DOWN button.
The adjustment range of the equalizer is ± 12 dB in 2 dB steps and ± 6 dB in 1 dB steps.
