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.

The DB1+ ATLTM
The ATLTM 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.

wafer-iw ™ control
- High frequency adjustment
Fine adjustment for perfect definition.
The wafer-iw“sports a three position tweeter level control to ensure a perfect tonal
integration into even the most difficult environment.
FLAT
The FLAT setting is perfect for the majority of installations.
HF-
Rooms with very little soft furnishings, like kitchens, can emphasise the high frequency,
so a reduction may be desirable by moving the switch to the HF- position.
HF+
Conversely a very heavily furnished absorbent room or if the wafer-iw“is placed
behind a perforated projector screen may need a small high frequency boost to
improve definition. Set to the HF+ position.
