Sophisticated Engineering

With 11.2 channel pre-outs on both conventional RCA sockets and balanced XLRs, the AV7705 is designed to work alongside high-quality external power amplifiers like the Marantz MM8077, MM7055 and MM7025. Not only is it a superb AV processor, the AV7705 is an extraordinary analogue preamplifier with an HDAM circuit board. Using Marantz-proprietary HDAMs, the preamp section of the AV7705 provides optimal channel separation, minimum crosstalk and enhanced signal to noise ratio for precise detail resolution and stereo imaging, while the ELNA capacitators of the analogue section ensure exceptional power and dynamic ability.
