Thank you for viewing this product from among many others. This time, I am listing a Pioneer A-30 integrated amplifier / power amplifier. I was using it as a power amplifier using the AV amplifier pre-out. Since amplifiers with main-in and power amplifier direct inputs are becoming rare, this is a valuable unit. I am listing it this time because I am changing my system. There are various amplifiers such as ONKYO, DENON, YAMAHA, SONY, and Marantz, but Pioneer amplifiers are faithful to the original sound. It is recommended as an amplifier for audio and theater use. Please check for scratches and scuffs as they are present from use. I was using it as a power amplifier with AB speaker output. The included accessory is a 3-pin universal cable. Please feel free to ask if you have any questions. Please understand that a conversion may be necessary as it is a 3-pin cable. The following is the official description.
