Introduction from the Technical Director

How can a loudspeaker be made to sound more natural? This is the question that drives our endeavour day-in, day-out. We’re

motivated by the quest to eliminate distortion from the most important element in your audio system. How far we’ve come can

be measured by the sound of Platinum II: the most accurate and beautiful loudspeakers Monitor Audio has ever made. Supported

by painstaking analysis and a lifetime of listening, their evolution has rened our technologies, inspired new discoveries and

achieved advances in every area of design - electrical, mechanical, magnetic, acoustic and aesthetic. The result is a speaker

range of exceptional quality, dedicated to raising your emotional contact with music and lm sound in all its natural glory. Built

by audio lovers, for audio lovers, Platinum II provides our answer to the primary challenge of speaker design. To the big question

we simply reply “like this”!

Technical Director

Company History

Since 1972, Monitor Audio’s near fanatical commitment to quality in every aspect of loudspeaker design coupled with its willingness

to innovate has inspired global recognition and acclaim. Daring to challenge design orthodoxy has been its signature approach.

When Monitor Audio launched its R852MD loudspeaker – the rst model to

incorporate a metal dome tweeter - it caused quite a stir. Until that time,

most metal domes were single-metal types made from copper or titanium

and virtually all sounded unconvincing. The R852 used an aluminium-

magnesium alloy dome and sounded signicantly better and smoother

than all of its single-metal rivals. It also incorporated ferro-uid damping/

cooling of the metal voice-coil former and a vented voice coil mechanism

for better heat dissipation. These radical design elements formed the basis

for successive generations of C-CAM® metal domes.

By consistently rening and applying the technology, Monitor Audio has

become the world’s foremost proponent of metal dome drivers. Monitor

Audio designs everything in house at their world headquarters in England,

so that it can optimise the incomparable blend of virtues that makes

Monitor Audio loudspeakers unique: clean, dynamic sound, superior build quality and innovative design. Because they share a

philosophy of excellence and a consistency of quality and voicing, loudspeakers of dierent types: on-wall, in-wall, oor and

stand-mounting, may be used together to create the perfect acoustic blend for any room.

In the strength and depth of Monitor Audio’s evolving product portfolio, the ideal of a universal whole-house loudspeaker brand

nds true expression. Decades of accumulated expertise and knowledge have rened the rare mix of innovation, reliability and

sheer performance that has propelled the brand to global status and on which acionados of music and movie sound have come to

rely.

PLW215 II Technology

The PLW215 II has been designed to produce wall-shaking bass using the best

technologies available to our team of designers and engineers. The sealed cabinet

houses a vibration-cancelling driver conguration featuring 2 x 15” sub woofer drivers

with an inverted surround, triple suspension, and a single layer edge wound, vented

voice coil, to enable a massive 42mm (peak to peak) of excursion. Drawing power

from the Hypex supply, each driver has its own 700w RMS Hypex amplier providing

a combined 1400W RMS power output. Controlling all of this is our bespoke, in house

designed, 172MHz DSP Core. The DSP can handle 3500 instructions per sample, with

139dB of dynamic range and 56-bit double precision processing all dynamically

updated by an 80MHz MCU. The Wolfson Microelectronics (Cirrus Logic) ADC & DAC @

24bit/48KHz (WM8786 ADC & WM8740 DAC) handles all of the important conversions.

The DSP is set by our proprietary application, SubConnect. It can be used straight

out of the box, being set by the control panel on the top of the sub woofer, or more

advanced settings can be adjusted using the application. Refer to page 11.

One of the features of the DSP is the room calibration. This, again using our own algorithms, measures the room acoustics and

smooths out any major peaks and troughs found in the room creating as a smooth a response as possible before applying the preset

equalisation curves. That can also be customised in the application. Refer to page 15.

Real Wood Veneers

Just like a human ngerprint, no two trees are identical. Each wood grain has an

exclusive aesthetic beauty that tells a story of a lifetime of growth. We use only

the highest quality natural wood veneers, hand selected and pair matched from

sustainable sources. Platinum II speakers are hand veneered after the cabinet

structure is made, and then coated with 11 layers of clear gloss piano lacquer.

These traditional techniques ensure close grain matching, and invisible veneer panel

joining. The exquisite grain denition and rich colour variation provided by our Santos

Rosewood and Natural Ebony veneers make a statement of quality, while blending

naturally with any interior style or decor. Each cabinet is a unique and natural work

of art!

Because of this, Monitor Audio Ltd. is unable guarantee that the veneer on dierent

pairs of speakers will be identical in colour or grain denition. We can only assure you

that the very best raw materials have been selected and applied.

Please refer to page 21 for advice on care and maintenance.

Amplier

1. USB Connector

This is provided to update the rmware and settings of the PLW215 II in conjunction with the SubConnect application (refer

to page 11). A USB cable is not included, please use the appropriate USB A to USB B cable.

2. RS232 Input

For use with home automation systems through a conventional RJ45 connector. Please refer to page 16 for the wiring

conguration and set up protocol.

3. 12 Volt Trigger Input ~ Centre Pin = +12Vdc.

For external power control from AV amplier/receiver to the PLW215 II (lead supplied), and to toggle between dierent

presets depending on set up via the SubConnect application (refer to page 11). The default setting controls the power. This

12 volt signal comes from the source amplier and supplies the PLW215 II with a signal to perform a predetermined action:

either to power up/down or to switch presets. When used to power PLW215 II up or down, the trigger is a very energy ecient

method of power control. The auto o timer and signal sense will not operate when the 12V trigger is connected.

4. IR (Infrared) Output

For use when controlling other IR devices via the PLW215 II. Connect the PLW215 II with a second device using a mono 3.5mm

jack connector and control the second device with its remote via the PLW215 II. This is ideal when the device is out of sight

or in another room.

5. Line Level Inputs (Stereo Left & Right)

For connection to a 2 channel/ stereo amplier system. Connection should be provided by a pair of high-quality signal cables

from the pre-out section of an amplier. Note: Cable lengths should not exceed 10 metres to avoid interference from other

electrical appliances.

6. RCA Line Level Outputs (Stereo Left & Right)

To be used to feed additional sub-woofers or power ampliers from the PLW215 II by ‘daisy chain’ type connection. The

outputs are link-out only connections and do not provide any form of ltering or amplication. There must be a signal on the

stereo input for the linked outputs to work.

7. LFE Input (RCA Type)

This input is to be used when connecting the PLW215 II to an AV amplier/ receiver. When using the LFE input, the crossover

function in the menu/ set-up is not used. This is due to the crossover function being controlled by the source to which it is

connected. Input between LFE and Stereo input is switched automatically.

8. LFE Output/ Link (RCA Type)

To be used to feed additional PLW215 IIs (or another sub woofer) by ‘daisy chain’ type connection. The output is a link out

only connection and does not provide any form of ltering.

9. Balanced LFE Output (Male XLR Type)

To be used when connecting to the balanced input on an additional sub woofer or amplier. This is the best method of

connection when using long runs of cables (over 10m, up to 100m). A balanced connection provides a much better (almost

noise free) method of connection over analogue audio type connectors.

10. Balanced LFE Input (Female XLR Type)

To be used when connecting to the balanced output on the amplier. This is the best method of connection when using long

runs of cables (over 10m upto 100m). A balanced connection provides a much better, almost noise free method of connection

over analogue audio type connectors.

11. Voltage Selection Switch

Factory preset to suit the voltage of the country of origin. This should not be adjusted.

12. IEC Mains Power Connector/Fuse Location

The PLW215 II is supplied with a three-pin mains input socket for connection to the mains supply. Use ONLY the appropriate

IEC mains lead provided with the product. Also tted is an external mains fuse. If a fuse blows during operation a spare fuse

is provided within the fuse holder for replacement. If you wish to change the fuse, you can do this by removing the IEC mains

lead and carefully levering out the original fuse from its holder below the IEC mains input socket (12a, opposite). If the fuse

blows again it is advisable to seek help from an authorised service agent. DO NOT attempt to re-t a further fuse as this could

result in serious damage to the amplier unit.

13. Mains Power Switch

Mains ‘rocker switch’ providing overall power o and on/ auto. In the on/auto mode, the unit will turn on when an input signal

is sensed or the control dial/ power button on remote is pressed. It will turn o after 20 minutes (default setting) when the

signal is removed (source turned o). Alternatively, using the 12V trigger (see above) to control the power by turning the

source on or o.

Positioning

The PLW215 II should be sited in the most suitable position,

preferably not directly in the corner of a room as this may cause

excessive bass boom. The optimal position is along the front

wall in the centre of the front left and right speakers. Obviously

this isn’t always going to be possible in all instances, so as

close to the optimum is advisable. Once a desirable position is

achieved it is important to check if the cables are long enough

to reach comfortably without being under tension. Leave the

PLW215 II unplugged until you are happy with its location and

the feet have been tted.

Never connect or disconnect any of the input connections

with the PLW215 II switched on.

Once in position, you should t the feet/ spike assemblies in

accordance with the guidelines below. Once the feet have been

tted, connect the signal cable(s) and mains cable and turn on

at the main switch.

Spiked Foot Fixing For Carpeted Floors

The spiked foot assembly incorporates a spike for use on

carpeted oors and also, a soft polymer pad (for use on wooden

or tiled oors).

Please ensure there are no hidden wires under the carpet, or

trailing mains leads that could be damaged by the spikes.

The foot comes fully assembled for use on carpeted oors. All

that is required is xing into the cabinet. This is achieved by

simply screwing the feet fully into the 4, threaded inserts in the

underside of the cabinet. If your carpet has a very thick pile,

remove the soft polymer pad from the foot to ensure the spike

goes right through the carpet onto the oor. Place the cabinet

in your desired location, and check that it is level on all sides.

If it is slightly uneven, unscrew the foot at the lowest point

and check again. Continue this process until the cabinet is fully

level. Use the locking nut on the foot to x it in place and to

stop any unwanted vibrations.

Spiked Foot Fixing For Wooden/Hard

Floors

For use on solid oors or where spikes are inappropriate, it is

possible to use the foot without the spike insert. To use the foot

in this manner carefully grip the knurled portion of the spike

and rotate anti clockwise to unscrew the spike fully.

You may nd it easier to rst remove the polymer pad to gain

more purchase on the spike.

The pad should be replaced before carrying out the levelling

operation previously described.
