This is an analog mixer from Mackie. Only the main unit and adapter are included. There is some dullness on the metal parts. Power-on confirmed. While there doesn't seem to be any crackling, the phantom power operation has not been confirmed as I do not own a condenser microphone. Please purchase with the understanding that this is a used item. Product Overview: A compact 8-channel analog mixer incorporating Mackie's quality, performance, and technology. Equipped with a 3-band EQ on all channels. Features a rugged metal chassis and high-quality components. The proven Mackie preamps provide high headroom and low noise, delivering high-quality sound.
