Commentary
A 10-band graphic equalizer that can control the 32Hz-16kHz band.
You can freely adjust it according to the sound characteristics of the listening room and your preference.
The resonance circuit, which greatly affects sound quality, uses a semiconductor inductor circuit that uses an operational amplifier without using a coil.
It is equipped with a spectrum analyzer using a large FL display, and a total of 11 bars, 10 bars for each band and one bar for a total display, blink.
You can use Lch, Rch, and L + R independently, and the display level can be adjusted by volume.
You can operate the recording system and monitor system independently.
It also uses a -6dB attenuator to prevent clipping when over-input is applied, and an EQ IN/OUT switch to pass the equalizer.
Equipped with a character switch that reverses correction only by switching the switch.
