Important
!

Our sole aim while designing loudspeakers is to recreate the true essence of an artist’s intention,
combining the maximum possible 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. We
also think that a well designed loudspeaker should be able to excel regardless of the audio genre,
and reproduce spoken word, rock, pop, or classical music with the same precision and accuracy.
Our unswerving passion for getting designs right has made this goal possible.
Thank you for choosing PMC products. Please read this user guide and install your new main
monitors according to the advice you’ll nd in the following pages.

Read these instructions and keep them in a safe place for future reference.
Heed all electrical safety warnings, including any on the loudspeakers themselves.
Do not use the loudspeakers near water.
Sufcient clearances and free ow of air are required around the control1200 and the
power2400.
Do not attempt to open 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.
Unplug this product from both signal source and power during electrical storms or when
unused for extended periods of time.
Packaging material can pose danger to the young and vulnerable. Ensure these items are
stored or disposed of safely.
PMC main monitors can produce sound pressure levels in excess of 120dB. Long-term
exposure to high levels of sound has the potential to cause hearing damage. Use care
when adjusting the system volume to ensure sound pressure levels remain within safe and
comfortable limits.
PMC main monitors contain very powerful magnets and therefore may have a detrimental
effect on nearby magnetically-sensitive items, such as CRT (tube-style) televisions or monitors,
and media such as oppy discs, cassettes and videotapes.
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.
The control1200 and the power2400 can produce hazardously high outputs, installation must
be carried out by trained staff.
PMC has made efforts to provide accurate installation information and good quality xings.
However, 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.
This product may contain nuts.

Introduction
Together, our MB, BB and QB reference monitor series comprise the world-class PMC Main Monitor
range — a trio of fully active three-way studio designs combining custom PMC-designed drivers,
Class-D electronics, carefully engineered DSP control and the company’s proprietary ATL ™bass-
loading technology to deliver the ultimate in power and precision, with forensic levels of detail.
The range’s combination of its highly damped, low-resonance cabinets and unique AT L™technology
ensures that unwanted mid-range energy is absorbed, while bass output is substantially extended
whilst having insignicant harmonic distortion. Every element of the design is carefully considered to
maximise transparency and resolution, all the way down to the absorbent material on the front bafes,
which reduce reections for improved dispersion and denition, allowing instruments and vocals to be
reproduced more vividly and with greater presence and clarity than ever before.
The drivers are bespoke PMC creations, with the HF and mid-range drivers common to all three designs.
The 34mm soft-dome tweeter is the most sensitive direct radiating tweeter available anywhere, with a
proven track record for delivering neutral, uncoloured high-resolution audio.
The perforated acoustic lens extends the response beyond 25kHz and controls dispersion to ensure
perfect integration with the highly efcient, low-distortion 75mm soft-dome mid-range driver through
the crossover region.
The MB and BB series feature extremely powerful, custom-tailored Radial bass units, renowned for their
dynamic response and thermal efciency — a 12-inch driver on the MB3, a 15-inch on the BB6 — while
the QB1-A features a quartet of individually matched PMC 10-inch piston drivers for the last word in
accurate, near-instantaneous transient response. Perfectly integrated with the ATL ™, these deliver
the clean, extended bass for which PMC is renowned, accurate all the way down to 20Hz (17Hz on
the BB6).
The 19-inch rackmount, externally housed electronics provide cutting-edge, ultra-low distortion
Class-D power amplication, with a DSP-based crossover providing perfect driver optimisation and
integration, as well as a non-invasive protective limiting system.
Remote control facilities enable the user to calibrate the system level and equalisation, as well as
select between analogue and AES3 digital inputs, and recall personal equalisation presets.
All of PMC’s Main Monitors are available as XBD-A versions, which feature a second bass driver in a
separate powered cabinet, increasing the available LF headroom of the system by 3dB. The XBD-
Active cabinet can also be used as a stand-alone subwoofer or LFE monitor if desired.
