Performance Features

  • Balanced Inputs and Outputs
    One pair of balanced high level inputs and balanced outputs for all six outputs.
  • Precision Tracking Variable Rate Volume Control
    Volume levels are controlled by a new multi-stage precision digitally controlled attenuator system with a tracking accuracy of 0.1dB. Levels change in 214 individual 0.5dB steps. The variable rate volume control circuitry provides an ideal rate of change with control rotation.
  • Tone Control with Assignable Bypass
    The bass and treble control circuit elements can be removed from the signal path of any selected input.
  • Alphanumeric Fluorescent Display
    The multi-function front panel display indicates the source selection and volume levels. The setup mode selections and adjustments are also displayed. The display intensity is fully adjustable.
  • Electromagnetic Input Switching with Level Trim Adjustment and Title Reassignment
    Digital logic integrated circuits drive electromagnetic switches on all inputs and operating functions for reliable, noiseless, distortion free switching. All eight inputs on the C45 can be matched in level, so that there are no abrupt changes in volume levels between the different inputs. Any of the eight inputs can have their input title reassigned to match the sources in the system.
  • Power Control Output and Trigger Assignment
    A power control connection for convenient turn-on of McIntosh power amplifiers, source components and accessories included. Two of the power control outputs may be assigned to activate when a given input is selected.
  • Multichannel Inputs
    There are two six channel inputs that are assignable for sources such as DVD-Audio player, audio CD player, super audio CD player and satellite receivers.
  • Moving Magnet Phono Input
    There is a precision phono preamplifier for moving magnet cartridges.

  • Optional External keypad Sensor Input
    There are provisions for connecting an external keypad and sensors which allow for enjoyment of your McIntosh system from other rooms in your home.
  • Fiber Optic Solid State Front Panel Illumination
    The illumination of the front panel is accomplished by the combination of custom designed fiber optic diffusers and light emitting diodes. This provides even front panel illumination, together with extra long life LED technology.
  • Glass Front Panel
    The famous McIntosh illuminated glass front panel ensures the pristine beauty of your C45 will be retained for many years.
