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
PS112s 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 PS112s
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 PS112s 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 PS112s 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.
