Description
Product description[Sansui] AU-?907NRA ?Used? The Ultimate ?-X balance circuit doubles the current margin of the driver stage compared to conventional models, achieving A-class operation with excellent dynamic characteristics, wide range, and high speed. The final stage is equipped with the NM-LAPT with a Pc (collector loss) of 200W suitable for high power amplification, which was used in the power amplifier B-2302, and the current margin during actual operation is improved, resulting in excellent playback. is possible. **Product specifications**Effective output (10Hz to 20kHz, (Both channels operate simultaneously) 190W+190W(6?) 160W+160W(8?)

We do not accept returns due to mistakes in the specification description, so please check the product specifications and images again on the manufacturers page before bidding.Product condition Used item in average condition condition comment Used item.Manufactured around 1998. There are scratches and scratches on the entire exterior, and it is in good condition for the model year. There is quite a lot of dirt on the top plate. I did some simple cleaning, but the dirt was not completely removed. There is a very strong cigarette smell coming from the unit. The operation is good, there are no problems with each input and output, and there are no large scratches or noises in the volume or tone. The subsonic button is recessed, but you can press it with the tip of your fingernail without any problem. Only the main body is included. *For older audio products, we have confirmed that they work as long as there are no audible differences or defects. We have not confirmed the exact output ratio using an oscilloscope. Please note that unless the sound is obviously strange, deterioration of internal electronic parts such as slight scratches or poor contact will be affected by the model year and will not be covered by the warranty.
