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

or 180

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.
