PMC PMC6 - Signal Flow

SIGNAL FLOW
Audio enters the monitor via an XLR connector which can accept analogue
or digital AES3 signals. Analogue signals pass through a low-noise, low-
distortion balanced input with variable gain staging, followed by a high
performance 24-bit 96kHz ADC. The digital input accepts 16- or 24-bit AES3
signals up to 192kHz. The crossover, user-control functions and non-invasive
driver protection systems are implemented in a powerful 32-bit DSP engine
before being distributed to independent 24-bit 96kHz D-A converters. The
signal path is completed by dedicated state-of-the-art Class-D power
ampliers directly coupled to each drive unit, reducing frequency response
irregularities and inter-modulation distortion.
* The diagram shows 4 channels of amplication, as used in the PMC6-2 and PMC8-2 models.
