Now you can customize sonic performance just like the pros. MCACC (Multi-Channel Acoustic Calibration System) provides built-in test tones that allow you to fine-tune your speakers’ channel level, delay, and even their placement in the room, for optimal sound reproduction. The VSX-D814-K powers six channels with an equal 100 watts (even a dual surround back speaker) and features advanced surround processing, with DTS-ES Discrete, DTS 96/24, Dolby Digital EX, and Dolby Pro Logic IIx decoding. Its sophisticated, heavy-duty construction utilizes one compact circuit board for all digital signal processing for exceptional purity, plus a double-precision Motorola 48-bit DSP engine that’s used in top theaters worldwide. The VSX-D814-K is ready for DVD-Audio and SACD next-gen audio, and provides the convenience of Advanced Quick Setup, a full complement of inputs, outputs, and terminals, and a new pre-programmed LCD remote. Also available in silver (VSX-D814-S).
