Amcron CTs600 ② 2-channel power amplifier. No accessories are included, but it was in use until recently, so there are no operational issues. The CTs series, especially the 2-channel models, have a high damping factor of over 3000, making them excellent for driving large systems. The sound output is lively and drives anything you play, and the unit itself is relatively lightweight, making it an easy-to-use amplifier. This particular unit has some distortion in the rack-mounting bracket, but it can still be mounted in a rack, so it's not a problem. Thank you.
