A message from Peter Thomas –

Peter Thomas

Owner & Chief Designer

“

Our sole aim while designing loudspeakers is to recreate the true essence of an artist’s

intention, combining the ultimate level of sonic resolution with solid engineering principles.

We believe that the same loudspeaker can be used throughout the entire audio chain,

from composer to studio or lm stage, post-production or mastering and then, nally,

the consumer. Our unswerving passion for getting it right has made this goal possible.

Thank you for choosing PMC products. It is now time for you to read the user guide, install your new twenty series speakers, and realise just how much you’ve been missing.

Page 5

Over two decades PMC has earned an

unrivalled reputation for creating the

world’s nest professional loudspeakers.

Simply put, our loudspeakers provide a

reference for the world’s highest prole

productions and events. They are found

at every stage of the creative process,

from conception to recording and

broadcast and, of course, in the home.

Our client list reads like a who’s who of the

sonically aware, with Prince,

Stevie Wonder, Robbie Williams, Coldplay,

Brian May, Universal, Sony, Dreamworks,

Deutsche Grammophon and the BBC

among the makers of movies and music.

Our loudspeakers were used in the

production of Titanic, Man of Steel, Skyfall,

WALL-E and during broadcasts of both the

Beijing and the London Olympics.

ology

turn signicantly reduces distortion. A spin-off

from the lack of distortion is that the upper

bass and midrange detail is not masked by

harmonic distortion residing in the very low

frequencies. The result is PMC’s characteristic

transparent midrange and fast, attacking

bass notes, all reproduced with outstanding

clarity.

A further advantage of the transmission

line approach is a cabinet that produces a

higher volume and greater bass extension

than a ported or sealed design of a similar

size, even if identical drivers were used.

Moreover, as the loading on the main driver

is maintained at all volumes, the frequency

response also remains consistent regardless

of listening level.

Casual late night listening or analytical studio

sessions can be conducted without the need

for high volumes to achieve maximum bass

response. A characteristic that is especially

suited to both the home enthusiast and

recording professional alike.

‘No other technology provides such a huge, rich room lling sound’

Technically speaking

PMC’s

(Advanced Transmission Line)

enclosures have taken loudspeaker design

to the highest level.

A PMC transmission line design utilises

sophisticated cabinet construction,

proprietary drive units and patented

absorption materials and techniques.

The benets are enormous compared to the

relatively simple sealed and ported models

currently available elsewhere.

The bass driver is placed at one end of a

long tunnel (the transmission line), which is

heavily damped with absorbent acoustic

material. This material is specied to absorb

the upper bass and higher frequencies that

radiate from the rear of the bass driver.

The lowest frequencies, which remain in

phase, then emerge from the large vent at

the end of the line, which essentially acts as

an additional driver. One advantage to this

approach is that the air pressure loading the

main driver is maintained, thus controlling the

driver over a wide frequency range, which in

All PMC loudspeakers are hand-built in the U.K. using individual

components that are matched to our reference model; this includes

the structural integrity of every cabinet and the testing and recording

of each component. This guarantees it will be within our strict tolerances

and ensures your purchase sounds identical to the original design.

Each completed loudspeaker then undergoes a set of objective and

subjective measurements - frequency response sweeps ensure that

the design meets our exacting performance criteria, and then listening

tests are conducted against the reference model using a wide variety

of material, from a benchmark BBC speech test to classical music,

pop and rock.

Unpacking

Please retain your packaging for future use as all PMC

cartons are durable, reusable and can be employed

to safely transport your loudspeakers should they be

relocated or returned for servicing.

Much of the packing is constructed from recyclable

materials, so if you are to dispose of it please do so in an

environmentally friendly manner.

Packing materials can pose danger to animals, the

young and vulnerable. Ensure these items are kept or

disposed of safely.

Resonance absorbing plinth installation

guide for oorstanding models

Resonance damping plinths and spikes enhance the performance and

stability of the oorstanding models in the range. The plinths attach to the

base of each speaker using M8 bolts. The twenty series spikes are reversible,

with spike or ball tips for use on either carpeted or more sensitive hard

ooring.

Tip

Carefully invert the loudspeaker so that its base is uppermost. Take care not to damage the top of the loudspeaker when it is upsidedown, the use of a soft cloth or square of carpet is suggested.

Position the plinth on the bottom of the loudspeaker so that its large curved edge is to the rear (same face as 4mm terminals/sockets). Ensure that the corresponding inserts in the base of the cabinet are aligned with the rebated holes in the plinth.

Locate the large M8 bolts and tighten them gently using the allen key

supplied until the heads of the bolts are ush with the plinth’s surface. Once the bolts are ush carefully tighten each bolt by half a turn

N.B. Do not over tighten. Over tightening will reduce the effect of the resonance absorbing material

Fully thread each spike with one of the supplied lock nuts. The spikes can then be attached to the plinth; they should point upwards whilst the cabinet is inverted.

Caution: the spikes are sharp and should be treated with great care

and may damage hard ooring if in direct contact

N.B. You have the option of using the ball tips for use on more sensitive

ooring

Re-invert the loudspeaker so that the spikes and plinth are at the bottom.

Once in position, level the loudspeaker by adjusting each spike in turn.

The nal step is to tighten each spike’s lock nut with the spanner

provided; this will ensure that the spike and loudspeaker are as rigid as possible.

Tip

Plugging them in

Caution

To avoid potential damage, please ensure that your power amplier(s) or receiver

is turned off before connecting or disconnecting your loudspeakers.

Cable & connectors

When selecting cables for use with your twenty

series loudspeakers, ensure that their

construction is of a high enough standard to withstand the rigors of everyday use

and that they are suitably terminated. While bare wire can be accommodated

by the twenty series binding posts, we recommend the use of either spade lugs or

4mm ‘banana’ plugs in order to maintain an electrical connection of the highest

integrity and avoid the possibility of short circuits. Please consult your dealer for

more information regarding cable lengths and termination options.

Polarity + & -

It is of vital importance to observe the polarity markings and maintain

positive-to-positive and negative-to-negative connections from amplier

or receiver to the loudspeaker. The twenty

series terminals are colour-coded to

aid in their identication, positive terminals are red, negative terminals are black.

Page 15

Standard / Single wiring connection

This is the most common, using a single cable with two conductors.

Connect using any of the two pairs of RED+/BLACK- terminals. Ensuring the

twenty

series terminals and gold linking bars are secure and the binding posts are

nger tight.

Advanced connection / Bi-wiring & Bi-amping

twenty

series models with four binding posts can be bi-wired or bi-amped.

By loosening all four rear binding posts, the gold linking bars can be removed

thus enabling separate signals to be fed to the low (Woofer) and high frequency

(Tweeter) drivers. Ensure the binding posts are re-tightened after the bridging bars

are removed. Both bi-wiring and bi-amping require the use of two lengths of cable

per speaker. Bi-amping requires two separate ampliers; one for each driver.

Please consult your dealer regarding the benets and the correct procedure.

The twenty.26 can also be bi-wired, bi-amped, tri-wired or tri-amplied. By loosening

all six rear binding posts, the linking bars can be removed so separate signals can

be fed to the LF (Woofer), MF (50mm Dome) and HF (Tweeter) drivers. Ensure the

binding posts are re-tightened after the linking bars are removed.

Both bi-wiring and bi-amping use two lengths of cable per speaker, tri-

wiring and tri-amping use three lengths per speaker. Bi-amping also

uses two separate ampliers; tri-amping uses three, one for each driver.

Please consult your dealer regarding the benets and the correct procedure.

When loudspeakers are new they will take time to reach their full potential.

It is often debated whether any solid-state equipment, such as CD players

or transistor-based power ampliers change with use, but the characteristics

of mechanical devices such as loudspeakers do alter and improve their

performance signicantly after a short ‘running in’ period.

The science is simple; as the soft material surrounding the dome or woofer

cone is exed it will eventually reach a point where it has optimum compliancy

allowing the drive unit to move more freely. This translates to greater accuracy

and speed of attack in the bass region and the mid and high frequency

produces a far more vivid audio picture. This short ‘running in’ period takes

approximately 50 hours of normal use.

50+ hours to run-in

With their unique

Advanced Transmission Line design, wide dispersion, ultra

low distortion and smooth bass roll-off, PMC loudspeakers are more forgiving of

difcult room conditions and placement constraints than conventional designs

- you will be able to achieve a superb sound throughout the room with little

effort. We do encourage you to spend some time experimenting in your own

room in order to achieve the very best results. Remembering that small changes

in location can often inuence system performance.

Room shape, size, construction and interior decoration vary immensely and

therefore inuence sound in different ways. The following guidelines are

suggestions for the starting point to locate your new speakers. Fine-tuning of their

positioning can start from here.

Tip

Positioning

Page 19

Tip

• Place the speaker so the front face is slightly forward of any large object

that protrudes into the room - this could be a replace, bookcase

or television for example.

See stereo set up diagram

• Ensure that stereo pairs of loudspeakers are equidistant from the listening

position.

• It is best to position the front left/right pair (and centre channel loudspeaker

if you have a surround system) at the same height, usually at ear-level when

seated at the listening position.

If any of the speakers are mounted above or below ear level, then angle the

speaker towards the listening position.

• The distance between your left/right speakers and the listening position

should ideally create an equilateral triangle. As a general rule, the width

of the audio picture will be narrow if the speakers are too close together. If

they are too far apart the picture will be wide but there will be less central

denition

Use a well recorded vocal track to judge the ideal spot.

• To further enhance the audio picture or soundstage the speakers can

be angled/toed-in’. Start with the speakers angled so they will cross

approximately 50cm (2ft) behind the listening position. (See stereo set-up

diagram) Varying this angle will also subtly affect the vividness of the audio

picture, so again experiment.

A simple well recorded band with vivid vocals will help to achieve the best

position

Positioning

Tip

Page 20

Bass / LF (Low Frequency adjustment)

Solid boundaries (i.e. walls, ceilings and oors) reect sound and help to contain

it within a room. They make a speaker sound louder the closer they are to them,

especially in the low frequency (bass) region.

This diagram shows the areas, that if a speaker is positioned, will either increase

or decrease bass - The darker the shading the more bass will be heard.

Placing the speakers in the corners will generate the most bass, and in the centre

of the room, the least bass.
