About the CR12/MC7108 Companion Products

The McIntosh products shown at right are logical companions for the CR12/MC7108. Separate
literature is available. Check with your McIntosh dealer for any late additions. McIntosh speaker
systems are also covered in detail in separate literature.

WK2, WK3, WK4 Keypad Controllers and R649 IR Sensor. 

The wall-mount, illuminated keypads

enable pushbutton operation and include IR sensors that relay commands from handheld
remotes. The CR12 can accommodate as many as four keypads or IR sensors in each of its four
zones. (See the separate McIntosh System Accessories literature for more on keypads and IR sensors.)

RCT3 Remote Translator. 

The Translator allows non-McIntosh components to be operated with

a McIntosh IR remote or keypad controller. It connects to the data outputs on the CR12. 

HC1 Home Controller. 

The HC1 connects to the CR12’s HOME data output and allows remote

operation of other home devices such as lights and movie screens.

PC3 AC Power Controller. 

The PC3 provides a total of 14 AC outlets (11 switched, 3 unswitched)

for automatic AC control of zone amps, audio sources, and video components. It connects to a
multipin jack on the CR12.

PC4 AC Power Control. 

The PC4 provides five AC outlets (four switched) for turning non-

McIntosh components on and off automatically when it is connected to the power control output
of a Control Center or Integrated Amplifier.

MR7084 AM/FM Tuner with RAA1 Remote AM Antenna. 

Likely to be the most-used source in

a multizone system, the MR7084 tuner is a thoroughly engineered broadcast monitor that reveals
the upper limits of AM and FM performance. The optional RAA1 antenna can be positioned away
from sources of interference (e.g., TV sets, fluorescent lights) for greatly improved AM quality.

MX132 A/V Control Processor. 

A single cable connection between the MX132 and

the CR12 integrates a McIntosh home theater and multizone system. This lets the two systems
share one group of source components. (The MX132 has a built-in AM/FM tuner and is supplied
with the RAA1 antenna, obviating the need for the MR7084.)

CR12/MC7108

Companions

acts literally at the speed of light, producing absolutely no audible side effects. An amplifier
with Power Guard will actually deliver clipping-free output well above its rated power.

Sentry Monitor

®

current protection. 

Sentry Monitor continually senses the voltage and

current of the output stage and confines it to a safe limit. Sentry Monitor does not limit
power output.

Thermal Cutout. 

If the cooling air is blocked and the power transistors become too hot, 

thermal cutouts protect against overheating until the amp cools.

Turn-On Delay.

This circuit delays operation for about two seconds after turn-on in

order to avoid any pops or thumps generated as other equipment turns on.

Soft Start inrush protection. 

Thermistors in the power transformer act as a cushion

against inrush current, eliminating component stress during turn-on. Soft Start is one of
many design details that contribute to the remarkable longevity of McIntosh equipment.

ost consumer electronics products are necessarily viewed
as short-term investments because either they don’t last

or they quickly become obsolete in some way. 

Coincidentally

,

manufacturers supply a steady stream of “new-and-improved”
products that you can buy. 

Again.

Behind every McIntosh is a fifty-year heritage of excellence,

proudly carried forward by every employee. No production

lines, no “price-point” engineering, no planned obsolescence.
McIntosh equipment is made to sound better and last longer. 

When McIntosh products are presented to customers, the

criteria they have been conditioned to overlook – reliability,
longevity, craftsmanship, ease-of-use, adaptability, pride of
ownership – suddenly leap to the top of their list.

The choice becomes clear: 

There is nothing like a McIntosh.
