Introduction
Key Digital
®
KD-MAX8x8 is an 8x8 matrix of analog and digital audio. Inputs and outputs support
balanced or unbalanced analog audio on a 6-pin phoenix connector while digital PCM audio
up to 5.1 channels is supported on RCA connectors. Analog and digital outputs may listen to
independent selections of the connected audio sources and each output features a digital signal
processor for volume, muting, 3-band EQ, balance, and delay. Systems greater than 8x8 may be
achieved using multiple units.
