Anleitung Zusammenfassung
The recovered audio signal will pass a digital as well as an analog filter stage to eliminate out-of-band components and is amplified to the maximum output power of 40 W to drive a speaker unit. By receiving the signal in a digital format, noise and quality losses that are inherent with conventional analog systems are avoided. The Model 1040 receiver/ amplifier will apply forward error correction to the received signal in order to maximize reception robustness. A built-in voltage step-up converter will lift the internal voltage to approximately twice the supply voltage when a larger output swing is required. The Model 1040 receiver/ amplifier will enter a Power-Down Mode if no valid signal is received. It will return to active mode when a valid signal is detected. © 2000 Amphony January 2000 1 2.4 GHz Digital Audio Receiver/ Amplifier Model 1040 Reference Data PARAMETER CONDITIONS MIN. TYP. MAX.
