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 62. The QAA-5415-25 is the same quad amplifier as the QAA-5415 but instead of 70 Volts it
is 25 Volts.
