Patent ID: 8571237

Claim:
A multimedia system, comprising: an audio power amplifier expansion card operably connected to the multimedia system and having a circuit board including (i) at least two audio channels; (ii) an audio power amplification circuit for amplifying audio power to at least 20 W RMS per channel; and, (iii) an onboard cooling system; wherein, the expansion card operably interfaces with a motherboard of a computer; a studio controller operably connected to the expansion card for receiving and processing input audio data, the studio controller having a receiver of audio data from one or more sources; a mixer of the audio data from the one or more sources; state selectors for controlling audio data input and output; and, a field-programmable-gate-array (FPGA) or application-specific-integrated-circuit (ASIC) microprocessor; and, a peripheral amplifier extension card operably connected to the system, the extension card comprising a second circuit board having (i) at least three audio channels; (ii) an audio power amplification circuit for amplifying audio power to at least 20 W RMS per channel; and, (iii) an onboard cooling system; wherein, the extension card operably interfaces with the motherboard of the computer and the expansion card; and the multimedia system comprises at least 5 audio output channels.
