Remark:
1. "*", Measured by pulse signal.
2. "**" Class D + AB, PWM Modulate power supply + Class AB analog topology.
3. The amplifier's PSU operates as a non-resistive load, so the calculation "Volts x Ampere=Watts" would not be correct.
4. All specifications are subjected to change without notice.
