Nine analog inputs include balanced and unbalanced line-level connections plus two independently configurable phono inputs, while the included DA2 Digital Audio Module adds seven digital inputs and high-resolution playback up to DSD512.\u003c\/p\u003e\u003cp\u003eBoth phono inputs can be configured for Moving Coil or Moving Magnet cartridges, allowing the C2800 to accommodate two turntables or tonearms without requiring an external phonostage. Gain is adjustable from 40 dB to 64 dB in 6 dB steps, while cartridge loading can be tailored over a wide range of resistance and capacitance settings.\u003c\/p\u003e\u003cp\u003eThe DA2 Digital Audio Module uses a Quad Balanced, eight-channel, 32-bit DAC and provides two coaxial, two optical, USB, MCT, and HDMI ARC inputs. Coaxial and optical inputs support PCM up to 24-bit\/192 kHz, while USB supports DSD512 and DXD up to 384 kHz. The MCT connection provides a secure digital path for high-resolution SACD audio from compatible McIntosh transports, and the complete DA2 module can be replaced should McIntosh introduce a future digital module.\u003c\/p\u003e\u003cp\u003eThree sets of variable balanced and unbalanced outputs give the C2800 considerable flexibility in more complex systems. The Main output and Output 1 include adjustable high-pass and low-pass filters for bi-amping, with level trim available on Output 1 to match amplifiers of different gain. Output 2 can operate in stereo or mono and can be used for a second audio system or powered subwoofer connection.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003ch4\u003eVacuum Tube Preamplification\u003c\/h4\u003e\u003cp\u003eThe C2800 uses three 12AX7A tubes and one 12AT7 in its analog circuitry, with the tubes visible through a glass panel in the top of the chassis.\u003c\/p\u003e\u003ch4\u003eTwo Configurable Phono Inputs\u003c\/h4\u003e\u003cp\u003eBoth phono inputs can be independently configured for Moving Coil or Moving Magnet cartridges. Gain is selectable at 40, 46, 52, 58, or 64 dB, allowing the C2800 to work with a wide range of cartridge outputs.\u003c\/p\u003e\u003ch4\u003eUpgradeable DA2 Digital Audio Module\u003c\/h4\u003e\u003cp\u003eThe included DA2 module incorporates 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 a compatible future McIntosh module becomes available.\u003c\/p\u003e\u003ch4\u003eHDMI ARC\u003c\/h4\u003e\u003cp\u003eAn HDMI Audio Return Channel input allows compatible televisions to feed audio directly into the C2800. Multichannel Dolby and DTS audio can be converted to two-channel playback for use through the stereo system.\u003c\/p\u003e\u003ch4\u003eFlexible Output Configuration\u003c\/h4\u003e\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\u003ch4\u003eProcessor Loop\u003c\/h4\u003e\u003cp\u003eAn analog Processor Loop provides 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\u003ch4\u003eBass and Treble Controls\u003c\/h4\u003e\u003cp\u003eElectronic bass and treble controls provide adjustment in 1 dB steps and can be bypassed independently for each input.\u003c\/p\u003e\u003ch4\u003eHigh Drive Headphone Amplifier\u003c\/h4\u003e\u003cp\u003eThe front-panel headphone output incorporates McIntosh High Drive circuitry and Headphone Crossfeed Director technology for dedicated headphone listening.\u003c\/p\u003e\u003ch4\u003eNetwork Control\u003c\/h4\u003e\u003cp\u003eA network connection allows operation of key functions through the McIntosh Connect app, including volume and input and output selection.
