Orban 622B (Vintage Parametric EQ) This is a type of EQ that has a rather bold effect, and its appeal lies in the analog texture that cannot be replicated by plugins. This unit has XLR connectors added to the input/output terminals, making it easier to handle. 【Condition】 ・Power on and sound output confirmed ・EQ function is working ・Overloads and oscillates when the level is increased. ・A slight signal from 1ch leaks into 2ch. (Slight crosstalk is present.) Due to the above reasons, this item is sold as junk. 【Appearance】 ・Signs of use and minor scratches commensurate with age ・Please check the photos Recommended for those looking for repair, parts, or collection. ------- I re-checked the operation because I had a question. I apologize for my amateur assessment, but the sound from 1ch leaking into 2ch is only very slight. Regarding the issue of overloading and oscillating when the level is pushed, if you search YouTube for the model number of this unit, you will find videos with similar sounds, and it seems to be an original specification.
