ABSTRACT:
A headset with an active crossover network is provided. The headset is coupleable to a first audio source using a wired connection and to a second audio source using a wireless connection. A controller is used to determine whether the first, or second, audio source is coupled to the active crossover network which, utilizing either analog or digital filtering, divides each channel of the incoming audio signal into multiple frequency regions sufficient for the number of drivers contained within the headphones of the headset. The output from the network's filters is amplified using either single channel or multi-channel amplifies. Preferably, gain control circuitry is used to control the gain of the amplifier(s) and thus the volume produced by the drivers. More preferably, the gain of the gain control circuitry is adjustable. The headset includes a power source that is coupled to the amplifier(s) and, if necessary, the network's filters. The power source can be included within some portion of the headset or included within the wireless interface. Alternately, an external power source can be used, for example one associated with the audio source.
