Performance Features
Important Information, Connector Information, Introduction and Performance Features
•
Patented LD/HP Technology
The McIntosh Loudspeaker Element features the patented
LD/HP motor structure. This design, when compared to
conventional Loudspeaker Elements, reduces distortion
significantly. It also increases power handling and
efficiency.
•
Large Woofer with Integral Heat Sink
Massive dual magnets with thick front and back plates pro-
vide an incredible heat sink for the voice coil. The voice
coil itself is wound on a 3" diameter aluminum bobbin to
further aid in the dissipation of heat. The ability to dissi-
pate heat greatly improves the driver’s capacity to perform
at high power levels and not suffer from power compres-
sion.
•
Rigid Woofer Framework
A black powder coated, die cast aluminum basket is used
as the framework for the driver. Such framework is neces-
sary to keep the driver’s moving components aligned dur-
ing the long excursions a subwoofer can produce.
•
Shielded Magnetic Field
The XLS112 may be used in Home Theater Installations
near a television receiver or monitor without causing the
television image to degrade. McIntosh has designed special
shielding around the magnetic structure of the XLS112’s
Loudspeaker Element to prevent interference.
•
High Power and Low Distortion
The XLS112’s 400 Watt Amplifier has very Low Total Har-
monic Distortion (THD). This 0.07% THD rating com-
bined with the low distortion of the McIntosh LD/HP
Driver provides exceptionally smooth and clean low fre-
quency response.
•
Power Guard
The patented McIntosh Power Guard circuit prevents the
XLS112’s Amplifier from being over driven into clipping,
with its harsh distorted sound that can also damage your
valuable Loudspeaker.
•
Remote Power Control
The turn-on method uses a standard McIntosh Power Con-
trol jack to receive a turn-on signal from a McIntosh Con-
trol Center. The alternate turn-on method for the XLS112
utilizes signal-sensing circuitry.
•
Signal Sensing Circuitry
In addition to the McIntosh Remote Power Control feature,
the XLS112 utilizes signal-sensing circuitry. This signal-
sensing circuitry is beneficial when the XLS112 is to be
located at a great distance from the pre-amp and running an
additional Power Control Cable for remote turn-on is not
feasible.
•
Phase Switch
The Phase Switch can be set to 0
0
or 180
0
to avoid phase
cancellation.
•
Balanced and Unbalanced Inputs/Outputs
Balanced connections guard against induced noise and al-
low long cable runs without compromising sound quality.
•
Variable Low Pass Filter
The variable Low Pass Filter selects the low frequencies
sent to the XLS112’s Power Amplifier when used with a
full range source signal. This filter can be switch out of the
signal path in Home Theater Systems.
• Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage protection
circuits ensure the XLS112 will have a long and trouble
free operating life. Built-in Thermal Protection Circuits
guard against overheating.
• Heavy Duty Power Supply
The XLS112 incorporates a regulated Power Supply, spe-
cial R-Core Power Transformer and extra large filter ca-
pacitors. All together these design features ensure stable
noise free operation even though the power line varies.
•
Gold Plated Input Connectors
The XLS112 Input Connectors are gold plated for superior
corrosion resistance and high electrical conductivity.
•
Special Enclosure
The XLS112 Enclosure is a combination of thick extruded
aluminum metal sides and rear panel with a textured black
powder coated finish. The front, top and bottom of the en-
closure is made from thick MDF covered with a thermal
vacuum formed durable surface also in a textured black
finish.
