Title:
AUDIO AMPLIFIER WITH LOCAL INTERFACE SYSTEM
Document Type and Number:
WIPO Patent Application WO2004112425
Kind Code:
B1
Abstract:
An audio amplifier includes a local interface system and an audio processing system. The local interface system may include a panel mounted display and a user input device. The local interface system may be utilized to locally configure and control the audio amplifier. In addition, when the audio amplifier is connected with a network, the local interface system may be utilized to configure and/or control other network connected devices from the audio amplifier. The audio processing system may process an audio input signal and provide an audio output signal. The audio output signal may be amplified in a power stage that includes a switching amplifier output stage. The audio processing system may dynamically configure the processing to optimize the frequency response of the power stage. The audio processing system may also receive gain commands from the local interface system or over the network to adjust a gain of the audio input signals.
