- Liner Notes
The output signal of the MC2205 passes through an output transformer, which is designed to match the output terminal of any impedance so that the maximum output is obtained for all frequency signals regardless of the output terminal. This transformer also protects the speakers in the event of an amplifier failure. When a DC component is mixed into the output, the transformer eliminates the component and prevents damage to the speakers. To prevent overloading of the output transistor, the output signal is always monitored by a Macintosh proprietary monitoring circuit. This circuit becomes high impedance when the output level exceeds the rated value, but this has no effect on the output. When the output reaches its maximum value, the monitoring circuit limits the signal supplied to the output transistor to prevent shorting of the output of the amplifier or damage to the output transistor. This monitoring circuit monitors the plus and minus sides of the output signal separately.
