General Notes
1. The following Connecting Cable is available from the
McIntosh Parts Department:
Power Control Cable Part No. 170-202
Six foot, 2 conductor shielded, with two 1/8 inch stereo
mini phone plugs.
2. For additional connection information, refer to the owner’s
manual(s) for any component(s) connected to the PS112.
3. In the event that the PS112 over heats, due to improper
ventilation and/or high ambient temperature, the protection
circuit will activate. The Front Panel Power Guard LED will
continuously indicate ON and the audio will be muted. When
the PS112 has returned to a safe operating temperature,
normal operation will resume.
4. The PS112’s Power Control will
function with 5 to 20 volts
applied to the Power Control
Input. Use a 1/8 inch stereo mini
phone plug to connect to the
Power Control Input. Refer to
figure 1.
5. To avoid damage, do not connect
the speaker level output
terminals from any receiver,
amplifier or integrated amplifier to the inputs of the PS112
Powered Subwoofer.
The McIntosh PS112 Powered Subwoofer is designed for
Home Theater and Music Reproduction. It has a 12 inch
LD/HP
1
woofer, a 400 watt amplifier and built-in high and
low pass filters.
The PS112 Powered Subwoofer’s performance is
equivalent to the quality of McIntosh’s legendary line of
Amplifiers, Preamplifiers, Signal Processors, Signal
Sources and Loudspeakers, without imparting distortion or
coloration of its own. It also complements the capabilities
and the remarkably low distortion of McIntosh Power Am-
plifiers.
Many of today’s loudspeakers are designed only for
Home Theater applications. Not so with the PS112. It is
also designed for the accurate reproduction of the low fre-
quencies contained in music. Motion picture sound effects,
explosions, and vehicle crashes require a wide dynamic
range and high sound levels. These sounds are such that a
speaker system having moderate distortion would repro-
duce them with little audible difference. This is not true
with the reproduction of music. Music is by nature and
definition harmonious. To reproduce it accurately, all forms
of distortion, both harmonic and intermodulation, must be
kept to a minimum. This has been the result of the design
of the new McIntosh PS112 Powered Subwoofer. Each
component in the device has been carefully designed for
durability, efficiency, and above all, low distortion. The
McIntosh PS112 Powered Subwoofer will reproduce music
accurately and function as an excellent Home Theater Pow-
ered Subwoofer.
