Technically speaking

PMC's ATL™ (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 benefits 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 specified 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

Pure diagram of a maze-like structure with no text, numbers, or symbols

twenty 22 cross section showing ATL™

turn significantly 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 filling sound'

Our meticulous attention to detail

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.

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 floorstanding models

Resonance damping plinths and spikes enhance the performance and stability of the floorstanding 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 flooring.

1 Carefully invert the loudspeaker so that its base is uppermost. Take care not to damage the top of the loudspeaker when it is upside-down, the use of a soft cloth or square of carpet is suggested.
2 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.
3 Locate the large M8 bolts and tighten them gently using the allen key supplied until the heads of the bolts are flush with the plinth's surface. Once the bolts are flush 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
4 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 flooring if in direct contact

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

5 Re-invert the loudspeaker so that the spikes and plinth are at the bottom.
6 Once in position, level the loudspeaker by adjusting each spike in turn.
7 The final 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.

Compact loudspeaker set up

The compact twenty series models are designed to offer exceptional clarity while taking up minimal space, either on stands or within audio/video furniture.

Connections

Caution

To avoid potential damage, please ensure that your power amplifier(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 amplifier or receiver to the loudspeaker. The twenty series terminals are colour-coded to aid in their identification, positive terminals are red, negative terminals are black.

Plugging them in

Connecting to an amplifier

twenty:21 twenty:22 twenty:23 twenty:24 twenty:C

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 finger 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 amplifiers; one for each driver.

Please consult your dealer regarding the benefits and the correct procedure.

Advanced connection / Bi-wiring & Bi-amping

The twenty.26 can also be bi-wired, bi-amped, tri-wired or tri-amplified. 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 amplifiers; tri-amping uses three, one for each driver. Please consult your dealer regarding the benefits and the correct procedure.

Running in or breaking in

Analog clock face showing 10:30 (no text or symbols beyond hour and minute hands)

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 amplifiers change with use, but the characteristics of mechanical devices such as loudspeakers do alter and improve their performance significantly after a short 'running in' period.

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

Positioning

With their unique ATL™ Advanced Transmission Line design, wide dispersion, ultra low distortion and smooth bass roll-off, PMC loudspeakers are more forgiving of difficult 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 influence system performance.

Room shape, size, construction and interior decoration vary immensely and therefore influence 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.

Positioning

- Place the speaker so the front face is slightly forward of any large object that protrudes into the room - this could be a fireplace, bookcase or television for example.

Tip 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.

Tip 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 definition

Tip 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.

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

Fine tuning for perfect bass

Bass / LF (Low Frequency adjustment)

Solid boundaries (i.e. walls, ceilings and floors) reflect 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.

5.1 Systems

The twenty series has been designed for perfect multi channel music or movie playback and the following diagrams display the ideal layout for the speakers.

Tip

No doubt the constraints of room size and shape will vary the distances from the listener to the speakers. Therefore use of the time alignment function of your surround processor will be important.

Tip

The guidance given in the ‘Stereo set up and ‘Fine tuning for perfect bass’ also apply to the set up of a surround system.

Note

7.1 Systems

In a system capable of full 7.1 Dolby® Digital Surround EX™, DTS® ES™, Blu-ray™ or HD DVD™ playback there will be two sets of surround speakers. The first pair should be positioned at 100° and the second set at 150°. (The centre is considered 0° while directly to the rear of the room is 180°). See Ideal 7.1 surround set up diagram.

Service

We are confident your twenty loudspeakers will afford many years of trouble-free listening of the highest order. But in the unlikely event that one or more requires repair, our unique manufacturing procedure, wherein the precise value of each component together with the response of the system as a whole is recorded, will ensure that any replaced parts will exactly match the performance of those originally included within each individual loudspeaker.

For any issues that might arise or for advice and service requirements, the primary point of contact should be your knowledgeable and authorised PMC dealer/distributor.

If you do not have a local representative please see www.pmc-speakers.com and click on 'where to buy'.
