Model with 12-band graphic equalizer for L/R channels, supporting 2-channel output. Brand: Victor - Model: SEA-G90 - Function: Graphic Equalizer - Number of Output Channels: 2 channels - Frequency Band: 16Hz〜32kHz I confirmed a maximum change of ±12dB for each L/R band. There is no crackling. REC select operation has also been confirmed. However, the tape 1 and tape 2 buttons for line output do not return when pressed, so there is no output. Therefore, this item is considered junk, and returns are not accepted. The exterior has some scratches on the right side. It is difficult to see in the photos. There are footprints from a previous amplifier on the top. ※Please note that the output of each band was confirmed simply using the free software Wavegene and Wavespectra, and is only a simple check, so no guarantee can be made. Shipping will generally be done on weekends, so please understand. Thank you for viewing.
