This is an AV amplifier. It can connect to a considerable number of devices. It can also connect to a subwoofer. It can connect to two sets of main speakers, A and B. It has two optical inputs, as shown in the third photo. The power cord is included, as shown in the fourth photo. The remote control is included, as shown in the fifth photo. Although I haven't checked all functions, CD and AUX work normally. The remote control is in good working order. This amplifier is a full digital amplifier.
