General:

1. Read all the safety and operating instructions, contained
in this owners manual, before operating this equipment.

2. Retain this owners manual for future reference about
safety and operating instructions.

3. Adhere to all warnings and operating instructions.

4. Follow all operating and use instructions.

5. Warning: To reduce risk of fire or electrical shock,
do not expose this equipment to rain or moisture.
This unit is capable of producing high sound pressure
levels. Continued exposure to high sound pressure
levels can cause permanent hearing impairment or
loss. User caution is advised and ear protection is
recommended when playing at high volumes.

6. Caution: to prevent electrical shock do not use this
(polarized) plug with an extension cord, receptacle or
other outlet unless the blades can be fully inserted to
prevent blade exposure.
Attention: pour pevenir les chocs elecriques pas
utiliser cette fiche polarisee avec un prolongateur, une
prise de courant ou un autre sortie de courant, sauf si
les lames peuvent etre inserees afond ans en laisser
aucune partie a decouvert.

7. For added protection for this product during a lightning
storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and dis­connect the antenna or cable system. This will prevent
damage to the product due to lightning or power line
surges.

Installation:

9. Locate the equipment for proper ventilation. For ex­ample, the equipment should not be placed on a bed,
sofa, rug, or similar surface that may block ventilation
openings; or, placed in a built-in installation, such as a
bookcase or cabinet, that may impede the flow of air
through the ventilation openings.

10. Locate the equipment away from heat sources such as
radiators, heat registers, stoves, or other appliance (in­cluding amplifiers) that produce heat.

11. Mount the equipment in a wall or cabinet only as de­scribed in this owners manual

12. Do not use this equipment near water; for example,
near a bathtub, washbowl, kitchen sink, laundry tub, in
a wet basement or near a swimming pool, etc.

13. Do not place this product on an unstable cart, stand,
tripod, bracket, or table. The equipment may fall, caus­ing serious injury to a person, and serious damage to
the product.

Connection:

14. Connect this equipment only to the type of AC power
source as marked on the unit.

15. Route AC power cords so that they are not likely to be
walked on or pinched by items placed upon or against
them, paying particular attention to cords at plugs, con­venience receptacles, and the point where they exit from
the instrument.

16. Do not defeat the inherent design features of the polar­ized plug. Non-polarized line cord adapters will defeat
the safety provided by the polarized AC plug. If the
plug should fail to fit, contact your electrician to re­place your obsolete outlet. Do not defeat the safety pur­pose of the grounding-type plug.

17. Do not overload wall outlets, extension cords or inte­gral convenience receptacles as this can result in a risk
of fire or electric shock.

Care of Equipment:

18. Clean the instrument by dusting with a dry cloth. Un­plug this equipment from the wall outlet and clean the
panel with a cloth moistened with a window cleaner. Do
not use liquid cleaners or aerosol cleaners.

19. Do not permit objects of any kind to be pushed and/or
fall into the equipment through enclosure openings.

CR12 Front Panel Sensor Disabling

If the CR12 is interconnected with a McIntosh C39 or
MX130 A/V Control Center, and both components are lo­cated together, the internal front panel IR sensor must be
disabled. This avoids interference problems caused by
sending IR commands simultaneously to the front panel
sensors of BOTH units.

1. Remove the top cover of the CR12.

2. With the CR12 front facing you, locate a small slide
switch on the large vertical circuit board near the top of
the right side behind the front panel.

3. Move the switch to the Right.

Installation

The CR12 can be placed upright on a table or shelf, stand­ing on its four feet. It also can be custom installed in a
piece of furniture or cabinet of your choice. The required
panel cutout, ventilation cutout and unit dimensions are
shown.

Always provide adequate ventilation for your CR12.
Cool operation ensures the longest possible operating life
for any electronic instrument. Do not install the CR12 di­rectly above a heat generating component such as a high
powered amplifier. If all the components are installed in a
single cabinet, a quiet running ventilation fan can be a defi-

nite asset in maintaining all the system components at the
coolest possible operating temperature.

A custom cabinet installation should provide the follow­ing minimum spacing dimensions for cool operation. Allow
at least 1-1/2 inches (3.8cm) above the unit so airflow is
not obstructed. Allow 17-1/2 inches (44.5cm) depth behind
the mounting panel, which includes clearance for connec­tors. Allow 1-1/8 inches (2.9cm) in front of the mounting
panel for knob clearance. Be sure to cut out a ventilation
hole in the mounting shelf according to the dimensions in
the drawing.
