The maximum continuous undistorted average power of 68W under the rated operating voltage also has a relatively complete overvoltage, overcurrent and overheat protection function. The most valuable thing is that it has the function of automatically resisting the current impact when the switch is turned on, so that the speaker can be safe work.

• 68W Cont. Avg. Output Power into 4Ω at VCC = ±28V
• 38W Cont. Avg. Output Power into 8Ω at VCC = ±28V
• 50W Cont. Avg. Output Power into 8Ω at VCC = ±35V
• 135W Instantaneous Peak Output Power Capability
• Signal-to-Noise Ratio ≥ 92dB
• An Input Mute Function
• Output Protection from a Short to Ground or to the supplies, via Internal Current Limiting
• Output Over-Voltage Protection against Transients from Inductive Loads
• Supply Under-Voltage Protection, not Allowing Internal Biasing to Occur when |VEE| + |VCC| ≤12V, thus Eliminating Turn-On and Turn-Off 0.004%. Transients
• 11-Lead TO-220 Package
• Wide Supply Range 20V - 94V
