"Introduction The new McIntosh C46 Audio Control Center offers a highly refined combination of useful operating features with totally transparent electronic performance. For example you can take advantage of the eight-band equalizer to achieve the finest possible reproduction of digital source music as well as valuable music from earlier recording technology. Combine a C46 with a McIntosh Power Amplifier and you will enjoy a system of unparalleled performance.
• Balanced Inputs and Outputs
One balanced high level Input and three balanced Outputs are provided.
• Precision Tracking Volume Control
Volume levels are controlled by a new Multi-Stage Precision Digitally Controlled Attenuator System with a tracking ac- curacy of 0.1dB. Levels change in 214 individual 0.5dB steps.
• Variable Rate Volume and Balance Control Selection The C46 Control Center’s Volume and Balance Control Cir- cuitry provides an ideal rate of change with control rotation.
• Eight Tone Controls with Assignable Bypass
The Tone Controls provide 12dB of boost or cut at center frequencies of 20, 35, 70, 150, 300, 600, 1200 and 4000Hz. When a Tone Control is in the center or flat position, all Tone Circuit Components are removed from the Signal Path of any selected input.
• Alphanumeric Fluorescent Display
The Multifunction Front Panel Display indicates the Source Selection, Volume and Balance Levels. Setup Mode Selec- tions and Adjustments are also displayed. The display inten- sity is fully adjustable.
• Electromagnetic Input Switching
Digital Logic integrated circuits drive Electromagnetic
Switches on all Inputs and operating functions for reliable, noiseless, distortion free switching.
• Input Level Trim Adjustment
All eight Inputs on the C46 can be matched in level, so there are no abrupt changes in volume levels between the different Inputs.
• Record Monitor Function
There is a Record Monitor Function for checking the progress of a recording from any of the eight inputs.
• Title Reassignment
Any of the eight Inputs can have their Input Title reassigned to match the sources in the system.
• Two Signal Processor Loops Separate front panel switched Signal Processor Loops are provided for the listen and record circuits.
• Precision Parts
Only the finest precision 1% tolerance resistors are used throughout.
• Low Distortion
Distortion levels of all types are less than 0.002%. Music is amplified with total transparency and accuracy.
• Moving Magnet Phono Input
There is a Precision Phono Preamplifier for Moving Magnet Cartridges.
• Remote Control
The C46 includes a Remote Control that allows remote op- eration of the Front Panel Controls and Push-buttons.
• Optional External Sensor Input
There are provisions for connecting External Sensors, which allow for enjoyment of your McIntosh System from other room(s) in your home via the Remote Control.
• Output Switching
Front panel Output Push-buttons control two Switched Outputs that allow sending signals to two separate Power Amplifiers.
• Fiber Optic Solid State Front Panel Illumination
The Illumination of the Front Panel Nomenclature is accomplished by the combination of custom designed Fiber Optic Light Diffusers and Light Emitting Diodes (LEDs). This provides even Front Panel Illumination, together with the extremely long life LEDs." - McIntosh
