McIntosh C2300 Owners Manual

More from McIntosh:

The C2300 tube preamplifier delivers a new level of performance and value. Potent engineering enhancements combine with smart, user-programmable features to deliver a truly extraordinary audio preamplifier.

The two phono preamplifiers, moving coil and moving magnet, are both 12AX7A tube based. Programmable Load and Resistance is selectable by remote control so the adjust- ments can be made from the listening position.

Bass and Treble controls are also adjustable by remote control. Individual tone settings and mono/stereo may be stored in memory for each of the 8 inputs. Tone Bypass may also be assigned which completely removes the tone controls from any designated input.

The C2300 is both beautiful to look at as well as listen to. The custom top cover features a silk-screened glass window which reveals a unique, slant-mount tube array. With its classic McIntosh glass faceplate, twin blue output meters and ergonomically pleasing rotary controls, the C2300 is poised to serve as the centerpiece of any fine music system.

EIGHT PROGRAMMABLE SOURCE SELECTIONS
All eight source elections accommodate unbalanced inputs while four of the either also accommodate balanced inputs. Any of 12 standard names can be assigned to a source selection and the panel display can be customized to indicate only available sources.

SILENT ELECTROMAGNETIC SWITCHING
Signal routing is accomplished through digitally controlled electromagnet switching devices. Precision switch contacts, isolated from environmental contamination inside inert gas-filled glass tubes, provide the most reliable, quietest and lowest distortion switching
possible.

VRV (VARIABLE RATE VOLUME) DIGIALLY CONTROLLED ATTENUATOR
The output attenuator controls volume over 214 steps of .5dB each with accuracy within .1dB. The volume vs. rotation rate varies as preamplifier gain varies and attenuation changes occur at eh zero crossings of the audio signal to prevent audible artifacts during adjustment.
