Introduction
The wafer™series of in & on-wall loudspeakers are a true breakthrough and encompass
PMC s award-winning professional monitoring heritage in a slim and elegant design,
ideally suited to match modern d cor and lifestyles.
PMC products are to be found in every demanding environment, from broadcast and
major film scoring to CD and DVD mastering. No other manufacturer can rival the
accumulated technical knowledge and high level of engineering excellence PMC has
developed over many years at the peak of professional monitoring. This expertise has
been encapsulated in the development and production of the PMC consumer range.
The wafer
™
series is ideal for stereo or all channels of a surround system. The wafer™has
been engineered with an identical tonal balance and similar dispersion characteristics
to all PMC models, thereby any combination will afford seamless integration and a
perfect audio picture. The professionally proven TLE1 active subwoofer can also
partner any of the range to provide the ultimate in low frequency power and
musicality.

Closing the loop between the studio and the home
The DB1+ ATL
TM
The ATL
TM
Approach
PMC 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 main 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 main driver.
The lowest frequencies, which remain in phase, then emerge from the large vent at
the end of the line, which essentially acts as a second 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 turn significantly reduces distortion.
A spin-off from the lack of distortion is that the upper bass and midrange 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 with
outstanding clarity. A further advantage of the transmission line approach is a cabinet
that produces a higher SPL and lower 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. Neither casual late night listening nor prolonged monitoring
sessions have to be conducted at high volumes to achieve maximum bass response,
a characteristic that is especially suited for both the home user and recording
professional alike.

Our 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.

General Usage Guidelines
Read these instructions and keep them in a safe place for further reference.
Heed all electrical safety warnings, including any on the loudspeakers
themselves.
Do not use the loudspeakers near water.
Clean only with a dry, lint-free, cloth.
Do not install near any heat sources such as radiators, ovens or other
equipment that produce excessive heat.
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 comfortable limits.
Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way or exhibits a distinct or sudden
change of operation or performance.
The wafer
™
series is not magnetically shielded, please ensure that they are
positioned at least 1 metre/3 feet away from items that could be damaged by
stray magnetic fields. Conventional glass tube (CRT) televisions and computer
monitors together with media such as floppy discs, cassettes and videotapes
are particularly susceptible.
PMC has made efforts to provide accurate installation information and good
quality fixings, PMC Ltd / PMC USA LLC cannot 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.

PMC s TT Technology™also allows for steerable image techniques which utilises
both tweeters to tilt the direction of the sound - a perfect solution if the wafer-iw

is placed much higher or lower than the listening position. It can also come into
play in some large environments when ceiling mounted. This mode should be tried
if the prime listening position is in no way directly below the wafer

but some 20
feet further forward or behind. Experimentation is best in this circumstance,
as room acoustics will play a large role in the result (see diagram below).

H-Line ATL
™
The ultra-shallow H-LineTM interior of each
cabinet is divided to create a long chamber,
which is in turn lined with special acoustic
materials. The result is an expansive, dynamic
soundstage, with the type of deep bass one
would only expect from a speaker many
times the size.
StealthBaffle
™
Standard in-wall and on-wall designs are
compromised by the large surface area of
their front baffle that surrounds the drive units.
This detrimental effect is best compared with
cupping your hands around your mouth whilst
speaking. PMC s acoustic specialists have
developed a unique, structured, absorbent
surface that prevents these unwanted
characteristic sound waves being reflected.
The drive units behave as though in free space
and concentrate pure, untainted audio
directly into the listening space.

Safety instructions
Instructions detailed in this manual assumes the installer has the required skill and
knowledge of the tools, local building and fire regulations and is aware of the
environment within which the speakers will be installed. If in doubt, consult a
qualified professional.
Before attempting to make the wall cut-out by using the enclosed template, ensure
your actions do not detrimentally affect the structural integrity of the building nor disrupt
any hidden services or other installations. E.g. power, pipe work, air conditioning, signal
cable etc.
This wafer
™
may contain nuts.
Before embarking on the installation ensure the kit is complete.
Check list
1 x Printed card positioning template.
1 x Perforated grille. (paintable)
1 x Grille removing hook
1 x Paint/dust mask (Within the grille - remove before operation)
1 x Cabinet including 8 concealed spring lugs and integrated paintable bezel/frame
Ensure correct orientation for optimum performance. (See pages 12,16 &17)
Produce the wall cut-out using the supplied template. (See Safety instructions
before taking action)
Check inside the cavity for obstructions that will impede the spring lugs on the
sides of the cabinet.
Tighten up the spring lug bolts that correspond with the spring lugs intended for
use until they appear fully from rebate in the sides of the cabinet. It is ideal if all 8
can be utilised, but if there is obstructions e.g. studwork etc. The recommended
minimum is 4.

Note the wall thickness, and tighten the spring lug bolts so the spring lugs move
close to the position they will remain once the cabinet is secured. This will avoid
aching arms and swearing.
Ensure the unused spring lugs are returned to their rest position and do not
protrude from the cabinet rebate. Failure to do so may result in rattling.
Connect loudspeaker cables (See connections, page No.18)
Install the cabinet through the prepared hole ensuring the cable are safely inside
the cavity. The spring lugs should click into place and temporarily secure the
cabinet from falling out from the opening.
Tighten the appropriate number of spring lug bolts required until the bezel/frame
and cabinet are fully secure.
Make any adjustments to the wafer
™
control switches - Vertical, Horizontal,
HF+, HF- etc
Remove the Dust/paint mask if painting is complete and there is no risk from dust.
Gently press the grille into place.
Removal of the wafer-iw
TM
from the wall
To remove the wafer-iw“from the wall/ceiling. Remove the grille starting from one
edge using the grille removing hook. Slacken all 8 spring lug bolts; this will retract
the lugs into the rebate freeing the cabinet. Do this operation gently.

Connections
To avoid potential damage, please ensure that your power amplifier(s) or receiver is
turned off before making or breaking any loudspeaker connections.
When selecting cables for use with your PMC loudspeakers, ensure that their
construction is of a high enough quality to withstand the rigours of everyday use and
comply with local regulations.
Bare, tinned, or 4mm banana plug terminated cable can be accommodated by the
wafer-iw
“
sprung binding posts.
To use the spring terminal function - push the terminal lightly until the two 4.3mm holes
of the inner and outer housings correspond. Place the cable through the hole and
release the terminal. Then test the cable is secure and there is no loose cable strand
protruding that may cause shorting.
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 wafer-iw“.
The wafer-iw
“
terminals are colour-coded to aid in their
identification, positive terminals are red, negative
terminals are black.
Customisation
Both the bezel & grille can be repainted to match the desired interior scheme.
When painting ensure the paint is applied as a thin coat and does not reduce the
pore size of the grille. Failure to do so will inhibit the performance of the wafer-iw
“
.
While painting, or when there is dust in the atmosphere, leave the Paint/Dust mask
in place not forgetting to remove it before operation.
NB: Do not attempt to paint the main cabinet or front baffle of the wafer-iw
