It provides 16 inputs in total—nine analog and seven digital—including balanced and unbalanced line-level connections, two configurable phono inputs, USB, HDMI ARC, and McIntosh’s proprietary MCT connection.\u003c\/p\u003e\n\u003cp\u003eBoth phono inputs can be independently configured for Moving Coil or Moving Magnet cartridges, with selectable gain from 40 dB to 64 dB in 6 dB steps. This allows two turntables or tonearms to remain connected while accommodating cartridges with very different output levels.\u003c\/p\u003e\n\u003cp\u003eThe digital section is housed in McIntosh’s DA2 Digital Audio Module, built around a Quad Balanced eight-channel 32-bit DAC. Its USB input supports DSD512 and DXD up to 384 kHz, while coaxial and optical inputs support PCM up to 24-bit\/192 kHz. HDMI ARC provides a direct connection for compatible televisions, and the MCT input accepts SACD and CD audio from compatible McIntosh transports.\u003c\/p\u003e\n\u003cp\u003eThree sets of balanced and unbalanced variable outputs provide flexibility for complex systems. The Main output and Output 1 incorporate adjustable high-pass and low-pass filters for bi-amping, with level trim available on Output 1, while Output 2 can operate in stereo or mono for a second system or powered subwoofer connection.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\n\u003ch4\u003e16 Analog and Digital Inputs\u003c\/h4\u003e\n\u003cp\u003eNine analog and seven digital inputs allow the C55 to accommodate an extensive collection of source components.

Gain is selectable at 40, 46, 52, 58, or 64 dB, providing compatibility with cartridges covering a broad range of output levels.\u003c\/p\u003e\n\n\u003ch4\u003eUpgradeable DA2 Digital Audio Module\u003c\/h4\u003e\n\u003cp\u003eThe included DA2 module uses a Quad Balanced, eight-channel, 32-bit DAC and provides seven digital inputs. Its modular construction allows the complete digital section to be replaced if McIntosh introduces a compatible future module.\u003c\/p\u003e\n\n\u003ch4\u003eHDMI ARC\u003c\/h4\u003e\n\u003cp\u003eAn HDMI Audio Return Channel input allows a compatible television to feed audio directly into the C55. Supported Dolby and DTS multichannel formats are converted to two-channel audio for playback through a stereo system.\u003c\/p\u003e\n\n\u003ch4\u003eEight-Band Analog Equalizer\u003c\/h4\u003e\n\u003cp\u003eAn eight-band analog equalizer provides ±12 dB of adjustment at each frequency band for tailoring tonal balance to recordings, loudspeakers, or room acoustics. The equalizer can also be bypassed.\u003c\/p\u003e\n\n\u003ch4\u003eFlexible Output Configuration\u003c\/h4\u003e\n\u003cp\u003eThree stereo sets of balanced and unbalanced variable outputs can operate simultaneously. Adjustable high-pass and low-pass filtering on the Main output and Output 1 supports bi-amplified systems, while Output 2 can be configured for stereo or mono operation.\u003c\/p\u003e\n\n\u003ch4\u003eProcessor Loop\u003c\/h4\u003e\n\u003cp\u003eAn analog Processor Loop provides unbalanced Send and Return connections for inserting an external equalizer, room-correction processor, tape deck, or other signal-processing component into the system.\u003c\/p\u003e\n\n\u003ch4\u003eNetwork Control\u003c\/h4\u003e\n\u003cp\u003eA network connection allows key functions to be controlled through the McIntosh Connect app, including volume and input and output selection.
