Fixed-pressure power amplifier and fixed-resistance power amplifier
Vibration Absorber
Pressure-tuning and resistance-tuning differ in output form:
1. The set pressure is not a fixed voltage but rather a constant voltage output format, which requires the rated voltage of the load to be fixed. Constant-voltage amplifiers are connected in parallel with multiple constant-voltage speakers, as long as the total power does not exceed the total power of the constant-voltage amplifier.
2. The fixed resistance power amplifier requires a constant load resistance output. In a fixed resistance power amplifier, if the load impedance changes, the power output will correspondingly change. A 8 ohm, 10 OW fixed resistance power amplifier connected to a 4 ohm load will output nearly 200 W.
Differences in Application:
For large spaces where sound quality isn't a high priority, constant voltage is used. Conversely, constant impedance is used for transmission limitations that can only cover distances up to 100 meters, so it's typically employed in smaller spaces where the sound quality is significantly better. Generally, broadcast systems utilize constant voltage output, while sound systems use constant impedance output.
