Abstract
An amplifier circuit is disclosed suitable for feeding a loudspeaker system having plural drivers. The amplifier circuit has an output stage and plural output connectors such that there is an output connector for each driver, wherein the output stage is connected separately to each output connector for independent connection to each driver. A method of feeding a loudspeaker system having plural drivers with an amplifier circuit having an output stage is also disclosed.
Claims18
An amplifier circuit in a single audio power amplifier suitable for feeding a loudspeaker system having plural drivers, said amplifier circuit having:
- a) a final output amplification stage with a low output impedance controlled output and
- b) plural output connectors such that there is an output connector for each driver, wherein said low output impedance controlled output of the final output amplification stage is connected separately to each output connector of the audio power amplifier via a separate damping output inductor for independent connection to each driver.
A method of feeding a loudspeaker system having plural drivers with an amplifier circuit in a single audio power amplifier, said amplifier circuit having a final output amplification stage with a low output impedance controlled output, said method comprising:
- providing said amplifier circuit with plural output connectors such that there is an output connector for each driver;
- and
- separately connecting said low output impedance controlled output of the final output amplification stage to each output connector of the audio power amplifier for independent connection via a separate damping output inductor to each driver.
An amplifier circuit configured to feed a plurality of drivers of a loudspeaker system, the amplifier circuit comprising:
- a single output amplification stage configured to output a controlled output having a low output impedance;
- a plurality of output connectors, each output connector configured to connect to a respective driver of the loudspeaker system via a separate cable;
- a plurality of damping output inductor circuits having a one-to-one correspondence to the plurality of output connectors, each damping output inductor circuit being connected to a corresponding output connector, wherein each damping output inductor circuit is connected to the single output amplification stage via a respective connection, and wherein the respective connections between the single output amplification stage and the damping output inductor circuits are separate from one another.
