Cooling fan speed is controlled by temperature sensors attached to the interior of the extruded aluminum cooling tunnel. The fan is normally off. When needed, the fan will automatically switch on, and speed is increased as needed for additional cooling. • Fully Discrete Design The MCC204 has a fully complimentary double balanced amplifier design and is identical to that found in McIntosh’s leading home amplifiers. • Balanced Inputs with Pass Through The Balanced Inputs cancel out interferenc
