Victor SEA-100 Graphic Equalizer Vintage audio, Victor's first graphic equalizer. Modern graphic equalizer circuits use semiconductors for simulated inductors, without using coils, but this unit is equipped with real coil components. White noise and sine waves of the corresponding frequencies were input, and the boost/cut effects of each frequency adjustment were confirmed. There are scratches, dirt, rust, etc. on the exterior. Although it is working, it is a very old device, so please understand that it is non-refundable and non-returnable. - Brand: Victor - Model: SEA-100 - Input Impedance: High/Low Switch - Frequency Adjustment: 60Hz, 250Hz, 1kHz, 5kHz, 15kHz - Connection Terminals: RCA Output Terminals, Input Terminals - Power Supply: AC100V 30W - Accessories: None Thank you for viewing.
