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.
·
Power Guard
The patented McIntosh Power Guard circuit prevents the
PS112’s Amplifier from being overdriven into clipping,
with its harsh distorted sound that can also damage your
valuable loudspeaker.
•
Flared Acoustic Bass Port
The Acoustic Bass Port in the PS112 has Flared Front and
Rear openings to eliminate air movement noise.
•
Shielded Magnetic Field
The PS112 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 PS112’s
Loudspeaker Element to prevent interference.
•
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 PS112 uti-
lizes signal-sensing circuitry.
•
Low Distortion
The PS112’s Amplifier has very Low Total Harmonic Dis-
tortion. This THD rating combined with the low distortion
of the McIntosh LD/HP Driver provides exceptionally
smooth and clean low frequency response.
•
Bass Enhance
The Bass Enhance Switch provides a Low Frequency Bass
Boost for use with video sources to enhance the impact of
low frequency sound effects.
•
Phase Switch
The Phase Switch can be set to 0 0 or 180 0 to avoid phase
cancellation.
•
Sub Frequency Filter
The variable Sub Frequency Filter selects the low frequen-
cies sent to the PS112’s Power Amplifier when used with a
full range source signal.
•
Hi-Pass Filter
The variable Hi-Pass Filter selects the midrange and high
frequencies sent to the Hi-Pass Out Jacks for use with an
external power amplifier and loudspeakers.
·
Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage protection
circuits ensure the PS112 will have a long and trouble free
operating life. Built-in Thermal Protection Circuits guard
against overheating.
•
Gold Plated Input Connectors
The PS112 input connectors are gold plated for superior
corrosion resistance and high electrical conductivity.
