Comes with a proper power supply. However, be aware that Channel 1 is not working and one of the rack ears is bent.

Using this Rolls RA163 distribution amplifier is easy. First, connect it to the proper power supply that comes with it. When setting it up, keep in mind that Channel 1 is not functioning, so you'll need to rely on the other channels. For the bent rack ear, you can still install it but be extra careful during the installation process. To maintain it, keep it in a dry and clean place. Regularly check the connections to ensure they are secure. If you notice any other issues, it's best to consult a professional.
