The AMX-3981 is an advanced, high quality audio processor which embeds up to eight (8) AES signals into a 3G/HD/SD video signal. Each AES input can accept different sample rates, or even asynchronous audio, and will be resampled at 48 kHz by a sample rate converter, which can be manually or automatically disabled in the presence of non-PCM audio. The AMX-3981 can simultaneously process up to 32 channels of audio (16 channels from the discrete AES inputs, and 16 channels of embedded audio). Functions include downmixing, proc amp, channel shuffling, mixing and loudness measurement. Options include automatic loudness control (ALC) and dynamic processing (limiter, compressor and expander). The AMX-3981 generates audio/video fingerprints (via an iControl option) to detect and measure lip sync errors in a broadcast facility.
