QAA-5415-70 and QAA-5415-25 Amplifier Wiring
QAA-5415-70 quad 15 watt amplifier has four 15 watt amplifiers. Each amplifier has one Class B 15 watt supervised
speaker circuit. Each circuit is wired such as to provide one separate speaker zone. The QAA-5415-70 may be
wired as Class A by using a QAA-4CLA Class A converter, see Figure 15. The QAA-5415-25 is the same quad
amplifier as the QAA-5415 but instead of 70 Volts it is 25 Volts.
