Signal to noise ratio reaches 100 dB at high level and volume is handled by a digitally controlled balanced attenuator accurate to 0.1 dB, with electromagnetic input switching, fully regulated power supplies and an R-core power transformer behind it. Maximum balanced output is 16 V RMS.\u003c\/p\u003e\n\n\u003cp\u003eSixteen inputs cover nine analogue and seven digital. Three balanced, four unbalanced and two phono inputs sit alongside the factory-installed DA2 digital module, which adds two coaxial, two optical, USB with DSD512 and DXD support, an MCT connection for McIntosh transports, and HDMI ARC for television audio. Both phono inputs are configurable as moving coil or moving magnet with gain selectable at 40, 46, 52, 58 or 64 dB. Three sets of variable balanced and unbalanced outputs can run simultaneously, with adjustable high-pass and low-pass filters for bi-amping and a third output configurable as mono or stereo for subwoofers or a second room.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#0F527F;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThree 12AX7A and one 12AT7 vacuum tubes\u003c\/li\u003e\n\u003cli\u003eTubes visible through a glass top panel\u003c\/li\u003e\n\u003cli\u003eTwo phono inputs, each switchable MM or MC\u003c\/li\u003e\n\u003cli\u003ePhono gain selectable at 40, 46, 52, 58 or 64 dB\u003c\/li\u003e\n\u003cli\u003eUpgradeable DA2 digital module with quad balanced 32-bit DAC\u003c\/li\u003e\n\u003cli\u003eUSB supporting DSD512 and DXD 384 kHz\u003c\/li\u003e\n\u003cli\u003eHDMI ARC input for television audio\u003c\/li\u003e\n\u003cli\u003eThree sets of variable balanced and unbalanced outputs\u003c\/li\u003e\n\u003cli\u003eAdjustable high-pass and low-pass filters for bi-amping\u003c\/li\u003e\n\u003cli\u003eThird output configurable as mono or stereo for subwoofers\u003c\/li\u003e\n\u003cli\u003eDigitally controlled balanced attenuator accurate to 0.1 dB\u003c\/li\u003e\n\u003cli\u003eRoon Tested, Control4 and Crestron Home certified\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color:#0F527F;\"\u003eWarranty\u003c\/h3\u003e\n\u003cp\u003eThis product comes with a 3-year manufacturer warranty.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#0F527F;\"\u003eWhy Consider the McIntosh C2800\u003c\/h3\u003e\n\u003cp\u003eThe output section is what distinguishes the C2800 from a conventional tube preamplifier. Three sets of outputs running at once, two of them with adjustable crossover filters, means a bi-amped system, a pair of powered subwoofers and a second room can all be driven from one preamplifier without outboard crossovers or splitters. The trim control on Output 1 then matches levels between two different power amplifiers, which is the practical obstacle most bi-amping attempts run into. Add two independently configurable phono inputs and a full digital section, and the C2800 is the control centre of a system rather than simply a volume control with tubes.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIdeal For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBi-amped systems using two different power
