Page 4 A message from Peter Thomas – arguably the world’s smartest loudspeaker designer and a truly obsessive audiophile. “ Peter Thomas Owner & Chief Designer Our sole aim while designing loudspeakers is to recreate the true essence of an artist’s intention, combining the ultimate level of 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 film stage, post-production or mastering and then, finally, the consumer.

Page 7: General Usage Guidelines
General Usage Guidelines 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. Do not install the loudspeakers near heat sources such as radiators, ovens or other very hot equipment, or in unventilated soffits or enclosures.
Page 8: Introduction
Introduction The IB2S-Active Series builds on PMC’s world-class monitor design pedigree, combining the finest drivers available with the unique (Advanced Transmission Line) bass loading principle, Advanced Transmission Line sophisticated Class-D amplification, and ultra-precise DSP control. The bass is loaded by PMC’s unique (Advanced Transmission Line) technology.
Page 9: Unpacking And Care
Unpacking and Care IB2S-Active Series monitors are packed in heavy-duty protective cartons. Please retain these to ensure that they can be transported safely if the need arises in the future. If you dispose of the packaging please do so in an environmentally responsible and safe way. Inside the packaging you will find: IB2S-ACTIVE IB2 XBDS-ACTIVE XBDS-ACTIVE...

An important benefit of the ATL approach ™ is that the air pressure inside the cabinet, loading the bass driver, is maintained.
Page 11: System Description
System Description The electronic heart of the IB2S-Active Series roll-off rates, optimising the contribution of is a powerful DSP stage which operates at a each driver, minimising distortion, and providing fixed sample rate of 192kHz. The balanced a flatter and more natural balance over the analogue line input level is conditioned by a widest possible listening area.
Page 12: User Eq Options
User EQ Options The IB2S-Active Series master cabinet remote control unit has facilities for five user-configurable equalisation presets, each of which can be named for easy recognition (eg. Frank, Geoff etc). These DSP-based user-equalisation options include LF and HF shelf responses, as shown in the graph above, each adjustable over a range of ±8dB in increments of less than 1dB, with fixed knee frequencies of 200Hz and 5kHz, respectively.
Page 13: Connections
Connections Caution To avoid potential damage, please ensure that the signal source is turned off before connecting or disconnecting your active loudspeakers. Connections The rear panel of the IB2S-Active Series carries various connectors for audio, control and mains power. Audio The electronically-balanced analogue audio input and the AES3 digital input accept 3-pin male XLR connectors, wired with Pin-1 screen (ground), Pin-2 signal positive (hot), and Pin-3 signal negative (cold).
Page 14: Running In
Running-In When brand new, PMC loudspeakers will take a short period of use before they reach their full potential. This is because the mechanical and acoustical characteristics of the bass, midrange and treble drive units alter slightly after manufacture as the flexible elements in their construction relax and reach their optimum compliancy.
Page 15: Applications And Accessories
Applications and Accessories Applications The large-scale performance of IB2S-Active Series monitors makes it appropriate wherever a clean, neutral and powerful presentation is required. Typically, IB2S-Active Series monitor loudspeakers are used for high-power midfield monitoring for music and speech recording and mixing, outside broadcast vehicles, radio on-air studios and television sound control galleries, home theatre and high-end domestic hi-fi, project music studios, post-production and editing suites, quality monitoring, music mastering, and A&R evaluations.
Page 16: Positioning
Positioning With their unique cabinet design, wide dispersion, ultra-low distortion, and smooth bass Advanced Transmission Line 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.
Page 17 When initially positioning the loudspeakers, ideally they should be located at two of the three points of an equilateral triangle, with the listener at the third. If the monitors are spaced too far apart the stereo image will be wide but central definition will be impaired. Use a well recorded vocal track to judge the ideal placement.
Page 18 Positioning (Cont.) Speaker Orientation The IB2S-Active Series is designed to be used upright to ensure optimum stereo imaging, tonality and amplifier cooling. Around the crossover frequencies each adjacent pair of drive units are inherently reproducing the same audio signal (although PMC designs employ steep crossover filters which minimises this), and so there are inevitably two sources of sound.
Page 19 Bass Response IB2S-Active Series monitor loudspeakers can produce significant bass energy below the frequencies at which they become omnidirectional. As a consequence, it is important to consider the effect of the boundaries of the listening room when placing the monitors. The use of plinth modules can assist in fine tuning the in-room bass response.
Page 20 Fine tuning for perfect sound Surround Sound Systems 5.1 Systems The IB2S-Active Series monitor has been designed for perfect multi-channel music or movie playback. The following diagrams indicate the ideal speaker layouts. The constraints of room size and shape will often force some loudspeakers to be placed closer or further from the listening position than is ideal.
Page 21: Operational Controls
Operational Controls The IB2S-A Active Series monitor is configured and controlled via the supplied remote control panel which has an LCD display with two rows of up to 16 characters each, plus four push buttons and a rotary control. The top push button accesses the configuration menu, with a back button to exit.

Page 34: The Pmc Range
The PMC Range The PMC range of professional monitors currently spans 22 different models, from the enormous BB5 XBD-A flagship system down to the diminutive DB1 passive speaker. However, every monitor is designed with the same care and attention, using shared families of drive units, crossover designs and amplifiers.
