Introduction

The McIntosh PS2K Powered Subwoofer is designed

for Home Theater and Music Reproduction. It has

a four 13 inch LD/HP woofers, each powered by its

own 500 watt amplier, plus built-in High and Low

Pass Filters and two Parametric Equalizer Filters for

subwoofer room correction.

The PS2K Powered Subwoofer complements the

capabilities and the remarkably low distortion of

McIntosh Power Ampliers and loudspeaker systems.

Each component in the PS2K has been carefully

designed for durability, eciency, and above all, low

distortion. The McIntosh PS2K Powered Subwoofer

will reproduce music accurately and function as an

excellent Powered Subwoofer.

Safety First

Please read the safety instructions included in a

separate document called Important Additional

Operation Information Guide.

Safety Cover

The PS2K is factory equipped with a clear safety

cover on the rear surface. Do not remove this cover

for any reason, and never make any other electrical

connection to the terminals inside.

PS2K

Important Information

1. The following Connecting Cable is available from

the McIntosh Parts Department: Power Control

Cable Part No. 170202 Six foot, 2 conductor

shielded, with two 1/8 inch stereo mini phone plugs.

2. The PS2K’s Power Control Input will function

within a 5 to 20 DC Voltage range. The Power

Control Output will only send a signal if a source is

connected to the Power Control Input.

3. To avoid damage, do not connect the speaker level

output terminals from any receiver, amplier or

integrated amplier to the inputs of the PS2K

Powered Subwoofer.

4. The PS2K needs to be connected to a dedicated

circuit with AC outlet. The type and size of the

dedicated AC circuit with outlet needs to be in

accordance with the local electrical wiring codes.

Always contact your McIntosh dealer and certied

electrician for additional information and assistance.

Note: 20 Amp, 120 volt AC circuit for use in the United States and

Canada only.

Packing and Unpacking the PS2K

Warning: The PS2K is very heavy. Please refer to

Unpacking instructions located in a envelope

attached to the shipping crate. Be sure to have the

appropriate manpower available to handle safely.

The PS2K is nished in a highly polished but durable

paint. However, it can be scratched, so please ensure

all sharp objects like rings, belt buckles, watches,

etc are removed prior to handling. Also please note

the PS2K has no protective covers or grilles over the

woofers. So please ensure not to reach and grab the

product woofers.

Once removed and placed in your listening area, the

protective lm may be removed by slowly peeling

o, all around the speaker. Also remove the protec-

tive rubber ring on the metal base.

cking the PS2K is the reverse of unpacking, so

please be sure to save all instructions and materials.

Performance Features

• Woofers with Patented LD/HP

Technolog y

The McIntosh Low Frequency Loudspeaker

Elements feature the patented LD/HP Magnetic

Circuit Design. This design, when compared to

conventional Loudspeaker Drivers, reduces distor-

tion signicantly. It also increases power handling

d eciency.

The die cast basket has an open air area under the

voice coil/spider assembly to prevent displacement

noise. The carbon ber cone with a corrugated

rubber surround has a six layer high temperature

voice coil and is rigid to perform as a near perfect

air piston.

All together these advances in woofer design

construction and materials produce the very

important rst several octaves of music, with

a high degree of accuracy and superb transient

response. This performance level rivals woofers

twice the size of the PS2K woofer.

• Gold Plated Input Connectors

The PS2K Input Connectors are gold plated for

superior corrosion resistance and high electrical

conductivity.

• Low Harmonic and Intermodulation Distortion

The PS2K Loudspeaker System is capable of

reproducing the full dynamic range of a symphony

orchestra with very low audible distortion of any

kind.

• Sealed Enclosure

The PS2K uses acoustic suspension design

techniques. This type of loading was pioneered

decades ago, and uses a linear air spring of the

enclosure to keep distortion low, suspension under

control at all times, and provide an extended low

frequency output below resonance.

• Large Woofer with Integral Heat Sink

Massive dual magnets with thick front and back

plates provide 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 dissipate heat

greatly improves the driver’s capacity to perform

at high power levels and not suer from power

compression.

• Rigid Woofer Framework

A black powder coated, die cast aluminum basket

is used as the framework for the driver. Such

framework is necessary to keep the driver’s

moving components aligned during the long

excursions a subwoofer can produce.

• Rigid Woofer Cone

The PS2K uses custom designed unied carbon

ber cone, dust cap, and coil mounting technology.

This provides exceptional cone rigidity to assure

no cone breakup under the most demanding

conditions. Additionally, the corrugated style cone

suspension provides extended linear cone travel

over most woofer designs.

• High Power and Low Distortion

The PS2K’s four 500 Watt Ampliers have very

low Total Harmonic Distortion (THD). This 0.05%

THD rating combined with the low distortion of

the McIntosh LD/HP Driver provides exceptionally

smooth and clean low frequency response.

• Power Guard

The patented McIntosh Power Guard circuit

prevents the PS2K’s Amplier from being over

driven into clipping, with its harsh distorted sound

that can also damage your valuable Loudspeaker.

• Signal Sensing Circuitry

In addition to the McIntosh Remote Power Control

feature, the PS2K utilizes signal-sensing circuitry.

This signal sensing circuitry is benecial when the

PS2K 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 Control

The continuously variable phase control provides

precise adjustment for the subwoofer phase.

• Balanced and Unbalanced Inputs/Outputs

Balanced connections guard against induced noise

and allow long cable runs without compromising

sou nd quality.

• Sentry Monitor and Thermal Protection

McIntosh Sentry Monitor power output stage

protection circuits ensure the PS2K will have

a long and trouble free operating life. Built-in

Thermal Protection Circuits guard against

overheating.

• Parametric Filter

The Parametric Filter provides simple peak or dip

ltering to the subwoofer output for room eect

correction. These lters may be used to indepen-

dently from any other room correction methods.

• Signal Pass Through

Signal Pass through is used for easy chaining of

one PS2K to another.

Dimensions

The following dimensions can assist in determining the best location for your PS2K Powered Subwoofer.

A Note on Placement:

It is important to keep your McIntosh unit out of direct sunlight and only use

appropriate gentle cleaners because the Organic Anodize can become discolored

over time.

While most products will maintain their classic dark features for their lifetime,

some situations can accelerate discoloration. The most pervasive culprit is UV

light, especially light directly from the sun, or high intensity spotlights. Even

high intensity short-term exposure can result in discoloration.

Chemicals can also alter the nish of the Anodize. Aggressive cleaners will take

their toll over time and actually etch away the Anodize nish.

Installation

Locating the PS2K

The optimal method for selecting speaker locations

includes the use of a real time spectrum analyzer

(RTA) operated by an experienced system installer.

An uncompromising installation would take into

consideration the oor, wall and ceiling coverings,

the type and placement of furniture and can even

include the architectural design of the room and its

construction materials. Frequencies 80Hz and below

reproduced by the PS2K Powered Subwoofer are

non-directional and will sound best located toward

the front of the room and away from corners. It is not

necessary to aim the front of the PS2K directly at the

listener.

A. LOW PASS FILTER

allows for an adjustable

cut-o frequency between 40Hz and 100Hz to the

subwoofer

. This setting is typically set to match the

HIGH PASS FILTER setting below.

The LOW PASS FILTER is always used if

nnected to Left and Right Inputs. To apply the

LOW PASS FILTER the TYPE Switch must be set

to SUB.

B. HIGH PASS FILTER allows for an adjustable

cut-o frequency between 40Hz and 100Hz from

the normal left and right loudspeakers. This lowers

distortion, prevents overloading the left and right

loudspeakers, and provides optimal blending with

the Subwoofer output.

To use the HIGH PASS FILTER, connect the L and

R ou

tput of a pre-amplier or integrated ampli-

er to the left and right inputs of the PS2K and

nnect the L and R outputs of the PS2K to your

power amplier(s) and set the crossover frequency

depending on the size and or specications of your

loudspeakers. Suggested settings would be 40 Hz

for very large loudspeakers like a XRT 2.1K or

XRT 1.1K, 60 Hz for medium size loudspeakers

such as a XR100, or 80 Hz for smaller speakers

such as XR50.

If setting the PS2K for Home Theater use, the AVR

ll typically have these settings internal. If this

is the case, then no L or R connection or setting is

required on the PS2K.

C. PHASE Knob sets the acoustic output phase

to provide optimum blending into your system

relative to its input. This knob is to help avoid

phase cancellation (characterized by a loss of bass

information) between the PS2K and any other low

frequency producing speaker in the system. Careful

listening while turning the PHASE knob will help

you determine if this eect will be benecial to the

system.

D. LEVEL Knob sets the gain / balance of the

subwoofer’s output to match the rest of the system.

Start with the LEVEL Knob in the center position

d perform the system level calibration on the

A/V Control Center or Surround Decoder for the

subwoofer level. If the subwoofer level can not be

set, adjust the PS2K’s LEVEL Knob to provide

adequate range during calibration.

E. STEREO INPUTS and OUTPUTS

Stereo Inputs are used in a two channel music

stem, or any system where a pre-amplier

or AVR is not applying LOW or HIGH PASS

FILTERs to any loudspeaker output channel. In

this case, connect the pre-amplier or AVR Left

and Right outputs to the PS2K Left and Right

Inputs.

Stereo outputs are used to connect to Left and

ght amplier inputs of an Integrated amplier,

AVR, or Left and Right loudspeaker amplier after

the HIGH PASS FILTER is applied. Never connect

the speaker level outputs of an AVR or 2 channel

integrated amplier to the Stereo inputs of the

PS2K.

F. MONO INPUTS

If connected to the output of another PS2K or other

bwoofer, then select SUB on the TYPE Switch.

If connected to the LFE output of a pre-amplier

r A

VR that has the ability to apply a custom lter

setting, then select LFE on the TYPE Switch.

G. MONO OUTPUTS connect to the input of another

PS2K or other subwoofers in a system. When the

TYPE Switch is set to SUB the output will be the

sum of both the stereo and mono inputs and the

internal LP lter of the PS2K is applied.

If connected to the subwoofer output of an

tegrated amplier then select SUB on the TYPE

Switch.

H. PARAMETRIC EQUALIZERS provide adjust

ments for room eect compensation. The lters are

plied only to the subwoofer output. The available

lter adjustments are Frequency, Bandwidth, and

Level.

The best way to set the parametric lters is with

e use of a spectrum analyzer and a noise source.

This will allow pinpoint accuracy of the settings.

However, if unable to use such a sophisticated

instrument, one may play typical music and listen

for boominess or lack of output in music or other

signal material.

Troubleshooting the Parametric Filter

If there is a lack of output, set P1 lter’s level to

B position.

If a boomy sound is heard, set P1 lter’s level to

B position.

Set bandwidth to center position. Now play the

gnal material and adjust the frequency control

until a correction is heard. Adjust the frequency

knob until it is centered on the eect. Next, adjust

the level control until the sound is more uniform.

Further adjustment of the bandwidth control

localizes the correction to only that band where the

action is desired.

The P2 lter may be adjusted in a similar manner if

e sound output is boomy or lacking character.

Note: 1. Each filter is fully independent of the other, so one

may be adding and the other subtracting from the

nominal output of the PS2K, or both adding or both

subtracting.

2. Both Parametric filters can be bypassed by placing

their LEVEL control to 0dB.

I. Input TYPE Switch

If receiving audio with lters already applied to its

gnal, set switch to LFE.

If receiving unltered audio, set type to SUB.

PS2K

J. POWER CONTROL IN and OUT

Connect a Power Control Cable to the INput from a

ntrol Center or Preamplier to automatically turn on

the PS2K when the Control Center or Preamplier is on.

Connect a Power Control Cable to the OUTput to send

e signal to additional subwoofers or other McIntosh

components to automatically turn them on as well. For

the OUTput to function, a source must be connected to

the Power Control INput

K. LOGO Switch controls the Logo lighting for home

theater purposes.

L. METER Switch controls the PS2K’s Meter Lighting

On/O. When in the ON position, the PS2K will also

accept power control signals to control the Meter

lighting.

M. POWER Switch

When set to the OFF position, the PS2K can only be turned

on b

y a Remote Power Control signal. When set to the ON

position, the PS2K will stay on depending on the position of

the AUTO ON/OFF switch. Using an active Power Control

signal will disable this circuitry.

N. AUTO ON/OFF Switch

When set to ENABLE, the PS2K will time out with the

sence of audio after 30 minutes. If Audio is detected, the

PS2K will trigger back ON. Using an active Power Control

signal will disable this circuitry.

O. CIRCUIT BREAKER should never activate under normal

conditions. If the breaker does activate, the tip of the breaker

will pop out. Reset the breaker by pushing in on the tip.

P. AC Input is used to connect the PS2K to an AC outlet.

Typical AVRs or AV processors will apply custom subwoofer lter settings.

Connect an AVR, Subwoofer, or LFE output to the mono subwoofer input of

the PS2K. The TYPE Switch should be set to LFE.

Home Music System Connection

Connection to a pre-amplier or music processor / integrated amplier is

made from the subwoofer output to the mono subwoofer input of the PS2K.

• If the pre-amplier or music processor has an available adjustable

crossover setting, use it and set the TYPE Switch to LFE. If the

pre-amplier or music processor does not have a adjustable setting, set

the TYPE Switch to SUB.

How to Connect

The McIntosh PS2K Powered Subwoofer may be turned On or O by two dierent

methods. The preferred method is to utilize the Power Control Signal from a McIntosh

A/V Control Center or Audio Control Center. If the Power Control Signal is not avail-

able, the PS2K has built-in signal-sensing circuitry which will automatically turn-on

e Powered Subwoofer.

1. Connect a power control cable from the McIntosh A/V Control Center or Audio

Control Center Power Control Out Jack to the McIntosh PS2K POWER CONTROL

IN Jack.

2. Connect a power control cable from the McIntosh PS2K POWER CONTROL OUT

Jack to the McIntosh Power Amplier Control In Jack.

Notes: • If two or more McIntosh PS2K Powered Subwoofers are being used in the same system, connect the

POWER CONTROL OUT from the first PS2K to the next PS2K POWER CONTROL IN Jack and

then onto the McIntosh Power Amplifier.

• The PS2K’s Power Control Input will function with 5 to 20 Volts DC applied.

• The PS2K Power Control output requires connection of a switched Power Control input to function.

3. Connect a Balanced Audio Cable from the McIntosh A/V Control Center or Audio

Control Center Subwoofer Out to the McIntosh PS2K MONO INPUT(S).

Notes: If two or more McIntosh PS2K Powered Subwoofers are being used in the same system, connect a

second Audio Cable from the first PS2K MONO OUTPUT(S) to the next PS2K MONO INPUT(S).

4. Connect the PS2K power cord to an active AC outlet.

Connection Diagram: Chain

To connect multiple PS2Ks to an A/V Processor in a single system use the following connections:

• The TYPE Switch should be set to SUB, this allows for signal path to go through the system’s LOW PASS FILTER.

• The LOW PASS FILTER should be set to the L and R loudspeaker’s rated low frequency point. This is typically 40 Hz for large loudspeakers, 60 Hz for medium

size loudspeakers, and 80-100 Hz for small loudspeakers.

• The HIGH PASS FILTER should be set to match the LP lter setting used above.

Connection Diagram: Two Channels

Home Music System Connection

Connection to a pre-amplier or music processor / integrated amplier

without a dedicated subwoofer output is made from the Left and Right

line level outputs to the Left and Right inputs of the PS2K. Using this

method allows ltering of low frequencies from the normal Left and

Right loudspeakers in your system, thus relieving them of the low

frequency burden and reducing their distortion and optimally blending the

output of the subwoofer and loudspeakers.

• The LOW PASS FILTER should be set to the L and R loudspeaker’s

rated low frequency point. This is typically 40 Hz for large loudspeak-

ers, 60 Hz for medium size loudspeakers, and 80-100 Hz for small

udspeakers.

• The HIGH PASS FILTER should be set to match the LP lter setting

used above.

Note: More than one PS2K may be chained in a music system setup. In this case, follow the

chain from the first PS2K to the second as described previously and set the TYPE

to SUB. Set the LP filter to match the lead PS2K and adjust parametric filters as

necessary for smooth performance.
