The cabinet is black with white lettering. Knobs are black aluminum. The PR41 is compatible with most any component with line level outputs, like CD player, tuner, tape recorder, etc, and with most power amplifiers, tube or solid state. Most power amplifiers have an input impedance in the range of 10KOhm to 100KOhm. The PR41 can also drive any of our electronic crossover networks.
