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 00 or 1800 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.
