11.2 Channel Full 4K Ultra HD AV Pre-Amplifier with HEOS Music Streaming Technology
For those building the ultimate home entertainment system, the AV7704 is a no-compromise 11.2-channel AV processor and pre-amplifier, designed for use with high-quality external power amplification or active speakers. It takes on board all the latest features, including Dolby Vision compatibility, unparalleled 3D surround sound decoding and HEOS music streaming, but dispenses with the internal amplification, allowing all the design and engineering within to be dedicated to producing the purest possible sound, and avoiding any possible interference from powerful amplifier sections creeping into the delicate digital and analogue signal sections. It’s long been common audiophile practice to separate pre-amplifier and power amplifier sections in this way, allowing power supplies and circuit layouts to be optimised for their specific purposes. The AV7704 even enhances audio quality by delicately handling all signals via the Marantz's own current feedback HDAMs preamp, before passing them to the high-quality 11.2 channel XLR or 11.2 RCA outputs and separate power amp. The absolute purist.
