Abstract: An integrated cinema amplifier comprises a power supply stage that distributes power over a plurality of channels for rendering immersive audio content in a surround sound listening environment. The amplifier automatically detects maximum and net power availability and requirements based on audio content by decoding audio metadata and dynamically adjusts gains to each channel or sets of channels based on content and operational/environmental conditions. A power supply stage provides power to drive a plurality of channels corresponding to speaker feeds to a plurality of speakers. The amplifier has a front panel having an LED array with each LED associated with a respective channel or group of channels of the multi-channel amplifier, and a control unit configured to light the LEDs according to display patterns based on operating status or error conditions of the amplifier.

Abstract: A method is provided, including: defining a plurality of frequency bins; sending, during a training phase, a test signal at different amplitude levels to one or more speakers, and gathering resulting test voltage (V) and current (I) points for the different amplitude levels and for each frequency bin; for each frequency bin, applying a linear regression algorithm to the gathered test voltage and current points for the different amplitudes to obtain a reference electrical impedance of said one or more speakers; sending, during a monitoring phase subsequent to said training phase, an audio signal to said one or more speakers, and gathering resulting new voltage and current points to obtain an operating electrical impedance for said one or more speakers for each frequency bin, determining a deviation between the operating and the reference electrical impedance, and, if the deviation exceeds a defined tolerance, reporting the deviation to a user.
