At PMC, we believe that music is what really matters; it’s what moves us and

gives us the passion for what we do. The company was founded because there

wasn’t a loudspeaker that was transparent enough to convey all of music’s

expressive power – and we knew we could remedy this.

One of our core beliefs has always been that the same loudspeaker can be used

throughout the entire audio chain, from composer to studio or lm stage, through

post-production and mastering, right to the listener at home. Discerning listeners

all over the world agree. Our designs are involved in every link of the music-

making chain, from the recording studio to listening at home, which means we

know exactly how to present music as transparently as possible, just as the artist

intended. This knowledge, combined with our love for music, drives us to create

products that you listen through rather than to. We want you to share the thrill of

the original recording because there is nothing like the emotional impact of true

musical communication.

Loudspeakers are where science meets art; we understand the science so that

you can connect with the art.

Oliver Thomas, Head of Design

Contents

Read these instructions and keep them in a safe place for future reference.

Heed all electrical safety warnings, including any on the loudspeakers themselves.

Tip

Do not use the loudspeakers near water.

Tip

Tip

The cabinet should only be cleaned with a dry, lint-free, cloth. Do not use solvents,

abrasives, waxes or liquids as they may be detrimental to the nish.

Tip

Tip

Four soft, self-adhesive feet are included with the twenty5.C. These can be

attached to the base of the unit to provide vibration-free operation.

Floor spikes are sharp; treat with great care during installation and use.

Tip

Tip

Do not install near any heat sources such as radiators, ovens or other equipment

that produce excessive heat.

Tip

Tip

Unplug this product from both source and power during electrical storms, or when

unused for extended periods of time.

Tip

Tip

Packing material can pose danger to the young and vulnerable. Ensure these

items are kept or disposed of safely.

Tip

Tip

High volume audio signals, however short their duration, have the potential to

cause hearing damage. Use care when setting the system volume level to ensure

playback sound pressure levels remain within safe comfortable limits.

Do not attempt to service the equipment. There are no user serviceable parts

inside. Please refer all servicing to PMC authorised personnel.

Servicing is required when the apparatus is damaged, exposed to moisture,

or exhibits a distinct or sudden change of operation or audio performance.

Tip

PMC has made efforts to provide accurate installation information and good

quality xings. PMC will not be held responsible or liable for injuries or property

damage – direct, indirect or consequential – arising out of use or inability to use

this product safely and properly.

Tip

Tip

twenty5 loudspeakers contain very powerful magnets and therefore may have

a detrimental effect if left in close proximity to magnetically sensitive items.

Do not use the Laminair vent as a grip to lift the loudspeaker as this may result in

damage.

TM

Advanced Transmission Line

Tip

Tip

The source of PMC’s legendary natural and wholly

realistic sound is the Advanced Transmission Line

(ATLTM) bass-loading technology.

ATL

TM

is an ingenious design which uses energy

generated by the bass unit in a much more

intelligent and efcient way than speaker designs

based on ported or sealed boxes.

In ATLTM loudspeakers, the highly braced cabinet

is lined with a multitude of custom-designed

acoustic materials that absorb all but the very

lowest frequencies. These are guided to exit from

a vent on the front-panel, extending the low-

frequency response and creating the impression

of a far larger speaker with an extra, ultra-high

quality bass unit.

ATL

TM

improves more than just the bass response:

because the low end is clean and clear it doesn’t

mask the rest of the music. Vocals in particular,

are beautifully projected and ultra-vivid.

ATL

TM

loudspeakers offer another benet. The ATLTM

bass extension does not change with volume

level – so even when listening quietly the bass

sounds balanced and well dened.

This cross-sectional view of the twenty5.24

loudspeaker shows the ATL

TM

cabinet

arrangement and the unique Laminair

TM

vents

‘Nothing else comes close to the clarity, timing, and dynamics.’

Taking ATL

TM

to the next level

With the launch of the twenty5 series, loudspeaker audio performance has been taken to the

next level with the addition of the Laminair

TM

aerodynamic vent.

The ATL

TM

design involves air moving under pressure at high speeds, and PMC’s Head of Design,

Oliver Thomas was able to apply aerodynamic principles transferred from his previous industry,

Formula 1 to the ATLTM concept.

The result is the unique LaminairTM aerodynamic vent which creates an even smoother, laminar

airow at the exit from the transmission line.

Tip

Tip

This innovative solution

reduces turbulence and

drag at the ATLTM vent,

reducing resistance,

increasing efciency,

eliminating air noise, and

provides bass with supreme

timing and the ultimate

dynamic range.
